jpeg image quality in Opera - Touch Diamond2, Pure General

I've noticed that the quality of jpegs is very low in Opera. If I compare an online image through Opera on my TD2 with the same image on my desktop PC with IE the difference is huge. Is there a setting in Opera for this?

If you're using 3G it's worth checking whether your network is compressing images it sends to your phone. I believe most do in the UK. You could contact them and get this changed if it's the case.
If you're using wifi and home broadband perhaps it's the UA (User Agent) setting for Opera telling websites which have mobile content available to send out small versions of pictures? It's just a thought...
I think I've noticed this too but haven't bothered to sort it out yet.

Thanks for the reply Pete_S. Yes, I'm using 3G mostly. I've just researched it a bit more and you're right, my network (o2) are compressing the images. The work-around for this, changing the APN user name to 'bypass', no longer works. Seems I'm stuck with it until somebody finds another work-around

solved!

Thought i'd post a follow up to this problem (yes, better late than never). It seems the o2 'bypass' workaround does still work but i had to toggle airplane mode on, then off, for it to kick-in. Seems a reset wasnt enough.
Anyway, image quality is now much improved, without the horrible compression.

Viewing a jpg image in PIE rather than downloading

If I put in an URL which ends .jpg rather than gives a webpage address, PIE asks me if I want to download the image and open it after downloading.
What I actually want to do is VIEW the image, without having to click "Yes" and then having to wait while it fires up the Picture Viewer.
Can I change this behaviour?
Can nobody help?
I tried exactly the same thing on an Orange E200 (very old Smartphone!) and it works perfectly - image displays straight away in the browser, no prompt for "download and open file".
I just want to be able to see the jpg directly in PIE, and refresh if I want. Easiest way of viewing my webcam!
timetex - don't know about the specific question, but why not just knock up a tiny bit of html just holding the jpg <img> and address. That way, you refresh the html page, not the jpg? This will also allow you to resize it to fit your screen etc as well.
V
Good suggestion, vijay, and if it was a computer generating the jpg, or I had control over it, that would be the first thing I'd look at.
However, its a camera. To be specific, an IP Network Camera I've got setup on my home network. It has its own built in webserver and makes use of an ActiveX plugin to "stream" video over http:// connection - so using my desktop PC, I just put the IP address of my router (or my domain name) into the browser, and the ActiveX / WebCam does the rest.
However, PIE will not accept the stream.
I've found a website detailing how to access specific data from the camera using either cgi commands or this function I'm using - the ability to view a single jpg image using a http://xxx.yyy.zzz/CamImg.jpg address.
As I said, this works fine on my Orange E200, but not in PIE on the MDA Pro. Annoying.
I guess I could get the camera to FTP the image to my hosted webspace and generate some HTML to view it there, but this just seems a silly way to do it, and rather wasteful of my bandwidth, as it would have to keep sending regular FTP just in case I wanted to view it (permanently overwriting the same filename every second or so) whereas if I connect directly to the camera, I automatically get the current image.
I could always stick a html file on my webspace and have THAT load the image.... hmm, I guess that could work?

This is something I really need !
Does anyone know if there are any chance to
display active X content ??
I'm not sure I understand
Surely the jpg must have an address that you're typing into PIE. In notepad on your PC (or pocket word etc if you're feeling adverturous) just knock together some html to display the image.
The html page will exist on your PDA, eg \storage\VJTestPage.html, and you just load that every time you want to see the updated jpg from your camera:
Paste this into notepad and change the urls for your jpg
Code:
<html><head>
[url="http://www.penny-arcade.com/images/2005/20051012l.jpg"][img]http://www.penny-arcade.com/images/2005/20051012l.jpg[/img][/url]
</head></html>
This assumes of course that the jpg's url is static, ie doesn't change.

Thats a nice workaround Vijay, to be sure.
But it fails to address the fundamental problem that is PIE's failure to view image files rather than download them.
Is there no way to alter a setting in PIE to VIEW jpgs rather than download them? The reason it's sooo irritating is that we don't want to keep all the images we want to view, eg browsing a forum thread with a frinds holiday photos in, you don't want to keep the photos, just see them!
Why can't it do this?
Do all the other pocket browers do this? I haven't tried Opera, and minimo is less use than a truckload of dead rats in a tampon factory!
Has anyone found a way round this?
you might try using the search button of the forum. It might help.

Web browsing: what are all the options right now?

I've been using VGA hack for a while against Pocket IE and really like the way it renders pages. But I hate the way VGA Hack works with almost everything else.
Can VGA Hack (or similar) be applied to specific apps only? Say PIE, Word and Excel only?
Failing that, what rival browsers exist?
Opera mobile and opera mini. Never used either and will try them out, but I never use the "1 column" mode in PIE and basically want pages to be as close as possible to a VGA desktop computer. I want framed sites to render well in particular.
Tabbed browsing *would* be nice but I certainly don't care that much.
Faster page rendering would be a real bonus. A couple of sites I visit (say http://www.todayonly.co.uk ) seem to take forever in PIE.
So, what else is there? There's some Japanese browser too, iirc, but how stable is that? How good is the rendering?
Opera is definitely the one you want. Works flawlessly with VGA, automatically and intelligently scales framed pages to display nicely, and will switch to classicl desktop view at a quick click. It even allows your device to identify as a desktop computer when querried by a page.
I disagree.
Pie+ for me is the most stable and feature packed browser. Not really a browser as such but a load of extensions to Pie.
In my view Netfront 3.3 is also a good option. Specially the fact that it supports Flash which Opera doesn't.
By the way I have also tried Mini Opera and in fact am writing this post using mini opera. Give it a try
Regards
Please check out the Web Browser category ( http://www.pocketpcmag.com/blogs/index.php?blog=3&cat=61 ) on my blog (the later articles have also been cross-posted to the General forum here at XDA-Dev) - it answers ALL your questions. It's really woth checking it out because, based on the info there, you will be able to make an informed decision on which browser to choose.
just try opera 8.6 version it will surely solve ur problem.
I have to Second the Netfront Suggestion
I have used a number of IE addins, and I used Opera during the Beta testing process. I find the in the end I keep coming back to Netfront. I like it enought that I finally did purchase a copy. It renders well in VGA. It has a number of layout formats so you can get a desktop like experience. What I like to use is the following.
Virtual resolution: 800x600
Zoom: 75%
Rendering: Smart-Fit
I also like to set quick render. This causes the page to display in a text layout while the browser retrieves the images and other layout information. This way if you just need a link from the page, you can click it before the whole page is drawn. This can be annoying though if you are trying to read the page because as soon as the browser was retrieved everything, it redraws the whole page, inturupting your reading. For me, this has not been a problem, but Netfront is flexible enough to suit most tastes.
They do offer a short free trial. I suggest checking it out.
Update:
OK, tried Opera for a few days and really, really liked it. However, sometimes it seems like it just doesn't respond at all. When it works, it great. When it's slow, it unusable. Basically, for features it's spot on but for responsiveness I've had to rule it out entirely.
I'm trying Netfront now and so far I'm hugely impressed. Accurate, rapid page rendering and seems to do everything it is supposed to do. I'll give it a week or so before I decide but it certainly looks like a bargain to me (under GBP£20 iirc - the price of a good sandwich)
still mostly happy with netfront,but how do you turn off the irritating way is fills the screen with the focused frame? Nice feature for 240x240 screens, but for vga it just slows me down.

I'm not sure what you're referring to, but you can always change the rendering mode.
To disable focus on frames navigate to "menu / tools / browser settings/ misc (tab) and uncheck box "enable smart frame operation"
This box is checked by default. With this box checked netfront fills the whole screen with a particular frame you have tapped upon.

Let me disagree. It's mostly with other Web browsers (most notably, NetFront) that seem to "freeze" when writing to (comparatively) slow (say, flash ROM-based) storage.
Of course, it's worth relocating the Opera cache (see my tutorial at http://www.pocketpcmag.com/blogs/index.php?blog=3&p=916&more=1&c=1&tb=1&pb=1 ), but also make sure you only relocate it to a well-optimized card.
By the way do u know that how can i change the location of cache (PIE) on to the storage card ?

Yeah. Please read for example http://www.pocketpcthoughts.com/articles.php?action=expand,42768
I think Opera for PPC works only with an acceptable speed if you relocate the cache NOT to a faster card BUT to virtual memory card.. there is a driver which does that. I'm greatly impressed with it..

Opera slower then the PIE?

Hey @ all,
i just tested a little around with my Advantage and 3.5G and found out that my Opera is never faster then 120Kbyte/Second... then i was wondering if this is the same on my WLAN. I ve got a 3.5 MBit DSL and tried first with Opera again 100-120 Kbyte/Second. After i tested with PIE. 450-540 Kbyte/Second...
Do i have to change some settings?
Thanks for your help
Kind Regards,
CoDeX2k
I've had a similar experience, and now use PIE over Operah. No idea why its like this!!

I did not do any benchmarks but I did find PIE faster. I have been using it over Opera and even Vueflo is set for PIE.
Maybe we need to tweak some settings in Opera as I do find the multiple tabs very useful.
Is there such a thing as tweaking the MTU or otherwise for individual applications on the Athena? Maybe Opera is slower because it processes the HTML differently and tries to adjust it for the screen while IE doesn't do as well of a job. Let me know if I'm wrong here.
Edit: I'm going to read through these to find out if there is anything that can be done. But I can't yet until later tonight or maybe this weekend. If you guys give it a go, let us know what you find if anything.
http://www.opera.com/support/service/customization/
its, I think Opera is definitely MUCH MUCH slower than IE. This is not just in loading itself , in fetching data, in displays, but also in accepting input from the keyboard. Opera is unable to cope with the high speed typing using TenGo software keyboard, whereas IE has no problem coping.
I'm sticking with IE from now until this problem is addressed in future version.
As per suggestions in this thread I tested PIE.
Oh my god (OMG for all you netizens) it is h o r r i b l e. It doesn't render anything correctly.
And I do not find that Opera is slower, but that could be due to the service providers crappy Edge (only ~160 kbps).
Opera renders pages quite nicely although sometimes it misses things, but overall it it is much more pleasurable to surf using Opera.
Strange, i also found Opera better, and the speed is not slower than IE as well.

Not much but here they are:
- Menu/Windows/....defaults.
- Menu/Display/, select Load images, Fit to screen, Landscape. Go to Zoom and selectd 90%. Found that putting it on 90% pages load better and faster on my end.
- Menu/Tools/, General tab: uncheck Jump to page content, check Block pop-ups, Minimum font size 10. History tab: 2000KB, Network tab: All SSL and TLS checked, all Proxy left blank, Misc tab: All checked but Use grab and scroll. I found that checking grab and scroll slowed down the browser.
I'm planning on trying to optimize it more if at all possible maybe sometime this weekend. Also planning on possibly optimizing some registry entries for communicating via Internet. If there is an equivalent MTU setting like on PC's then that needs to be optimized because if you're going from GPRS to WiFi or 3G the settings won't be the same.
Edit: One more thing, if you didn't know about the opera.ini file here is a little info on that. I'm working on figuring out the best settings for this as well. Since I don't know when I'll have time to finalize this here is the info so you guys can look into it yourselves and not have to wait on anyone. ;-)
The file is located on your device at:
\\Application Data\Opera\opera.ini
You can find most of the preferences defined here:
http://operawiki.info/OperaINIFiles
I haven't had a chance to find where in the registry you can find connection optimization data but I know there are programs out there that you can setup profiles for each connection type, GPRS/WiFi/3G/etc...I wonder if these programs allow you to setup MTU's and other settings. Can anyone provide info on this?
Today when I used my Opera it was okay
It appears that our units are having erratic sluggishness at times. Most of the time it is fast but for no apparent reasons things started freezing up.
I'm begining to suspect this might be due to compaction thread activities going on, where the file system just simply takes up most of the available resources.
I thought the following information might be useful in order for us to understand what is really going on with our device.

What does everyone else think?
Everynow and then when I click on a URL in an email etc Opera does not launch. The wait cursor spins and spins to no end. I then try to start Opera myself using its icon ... same result. I close all running applications wondering if this is memory related and try Opera again ... no difference. So in short I've had it with Opera for now so I want to go PIE way.
Does anyone know how I can change the system default such that each time I click on a URL PIE opens up instead of Opera?
Thanks a lot for all your help.

Opera Mobile 10 Beta is now out on Winmo, Anyone tried it on the HD2 yet ?

http://www.mobiletechworld.com/2009/11/18/opera-mobile-10-beta-available-on-windows-mobile/
Did anyone try it on the HD2?
ooh thanks for the tip, downloading and trying now.
First impression: Wow it loads up quick. Probably at least 1 third of the time of 9.5
It uses HTC keyboard rather than the Opera one as in Mini 5.
Just tested loading engadget on 10 and 9.5 and they came out about the same, around 16 sec on low strength wifi connection.
Tried testing a few sites and if anything 10 might be slightly slower at downloading and rendering, only by a second though and I might not be timing that accurately. Overall though it's much faster to load so one benefit there.
Note: Just realised I've been doing above tests with Opera Turbo off. doh. Re-testing with new sites now.
OK, with turbo on, thinkbroadband.com loads just under 5 seconds on Opera 10 and on 9.5 it's just under 9 seconds.

Thank you for letting us know. It looks promising.
Does multitouch work naturally like in original 9.7 version included in hd2?
What I mean is, does the multitouch gesture zoom in the web page (enlarging the textsize etc) or does it zoom in the window (like non-supported applications manually added through registry)?
Thank you.
I think it's 9.5 included with HD2, but no, the multitouch isn't working in 10 beta.
Also need to find a way to replace it as the default browser...
Edit: Updated tests above with turbo on
Edit 2, I was wrong, it is 9.7 sorry.
No auto-rotation like in 9.7 either.
Another noticeable difference is the page updates way quicker. E.g. browsing my rememberthemilk.com tasks page on 9.7, there's a lot of the checked pattern when swiping around the page. On 10 there is none at all.
@ Biffy
Thank you for your quick response.
Is the executable named as "OperaL.exe"?
If not, did you try to rename it? This might restore multitouch gestures and auto-rotation
Will check the OperaL.exe, but won't I need to move it to the overwrite the default folder maybe?
Also tried swiping around engadget.com, in 9.7 it's not hard to get a bit of the checker pattern even after the page is loaded. On 10 I can't seem to get any and think it may be smoother overall too.
Edit: Renamed exe to OperaL.exe but now no pages seem to load...
It's nice to see the tab limit has been increased from the tiny amount on 9.7
I'm not sure if this new version will be work good with our htc hd2... because the opera version by default are optimised for our devices, not likely the beta version of opera.
(omg sorry for my poor english)

I don't think that it is necessary to have it in the same location. But it may be necessary for the executable to have the same filename, window name & class name (you can check the last 2 using a task manager, but the filename is the easiest to start with).
You can increase the maximum number of tabs in version 9.7.
See the tips & tricks thread or type opera:config in your opera mobile
Just trying to sort out my wifi problem, as no connections were working. Then will retry as OperaL.exe
I knew about the tabs in 9.7 but it's still nice in 10 it's better by default, one less thing to have to tweak.
My connection is working again after a reset, don't know what happened there...
Renaming to OperaL.exe hasn't changed anything. The default executable is Opera9.exe, would it be worth trying that, or something else?
Edit: Opera9.exe doesn't help either. Guess it's not going to be such a simple fix.
Got to say, I like the way the interface is heading.
Not too worried about the lack of HD2-centric optimisations, that will surely come later.

Hopefully there will be a solution, so that Opera 10 will remain optimized for our device.
I think the thing I miss most is the auto-rotation. As it makes zoom un-necessary on lots of pages.
Pinch & zoom doesn't work, either auto rotate and no much differences from 9.7, better ui, opera turbo and little more.
and opera turbo loads faster yes, but it is a ****ty compressor that makes the images looks like crap.
I still with 9.7
been playing with Opera 10 this morning - FAST.
i guess you either love or hate Turbo, but I love it.
The only issue I am having is that the links from the sense browser page still open in 9.7, but 10 has made itself default for mail links, so a little muddled.
Turbo got better .. it can play animated gifs now for example (it couldn't before). But you can;t set image quality, and the default quality is very bad.

Does Opera 9.7 compress images?

Is it my imagination, or does the default Opera installation compress pictures even when turbo mode is switched off in the opera:config settings? If so, is there any way to stop it doing it?

It's not your imagination mate. This has bugged me for a long time. I can open a fullscreen image on my PC and it looks great, but on my device (whatever it is - not just HD2), a fullscreen image in Opera looks blocky and low res (well, not low - just too low for my liking).
I don't think an answer has been found for this yet. I'd love to know how to "fix" this.

They aren't compressed in IE - just Opera. Besides, it still does it when I use Wifi.
I'm not on O2 and this happens to me. It's not a problem if I access the internet on my laptop using my phone as a modem either.

Its not that because images look the same on all networks and even Wifi.
Looking at this thread in Opera 9.7, Opera 10 beta, and IE they actually all look the same! My Bagpuss avatar looks really blocky. Maybe that's something to do with my network settings? I have a t-mobile branded phone, stock ROM.
Next time I'm near a WiFi hotspot I'll see if it makes any difference.
I was wondering, could this be at least partly to do with the scaling algorithm used for zooming?
Shasarak said:

I could believe that scaling would make the image look a bit crappy (very technical term there ), but with Opera it does look exactly like an image that's been reduced in size and then had its size increased again. Even a bad shrink of an image would look better than Opera does at 1/2 the image's full size.
I do hope this thread comes to some conclusion about this, unlike previous threads that have just disappeared. Fingers crossed!
Sorry I always thought it was just O2 alone
I agree that its to do with the crappy zooming in opera, as in IE zooming to 100% give a nice picture
In the interests of making sure we're all on the same wavelength, would someone like to post a link to an image which particularly exhibits the problem? If you are saying that (when browsing on an HD2) Pocket Internet Explorer makes the image look okay, but Opera 9.7 doesn't, then, again, could you link to an image which makes that difference especially clear?
For example, looking at this thread on my HD2, my avatar picture looks very blocky, but it looks equally blocky using PIE - it's only using a desktop PC browser that makes it look good. That could just be an oddity of this particular forum, I guess, or it could be that there's a problem with my network settings rather than with Opera.
Am I allowed to use links to images on photobucket.com? Given that the sole reason that site exists is to allow people to deep-link to it, hopefully that'll be okay.

This is actually slightly worse than it appears on screen as I've used BSBTweaks to do the screenshots, and it takes screenshots in JPEG format. If someone can tell me an easy way to take HD2 screenshots in .bmp or .png format, I can redo them.
HD2 is rendering in 16bit, your PC is rendering at 32bit. Simple as that. Open the same webpage on the iPhone and you'll see (it renders in 32bit..).

Definitely not "as simple as that". I've edited my post above to include images captured from desktop IE with my PC running in 16-bit colour. You can see they're almost indistinguishable from the 32-bit versions. Certainly no signs of macro-blocking.
I thought it was a long established fact that operators throttle JPEG images to help save bandwidth.
I am pretty sure T-Mobile do. Try saving an image from either IE or Opera on your mobile device and then view it on your PC.
Now visit the same page (with the same pic) and save it directly from your PC and compare the two.
The one off your mobile device will look gash in comparison to the one form your PC as the Bagpuss pics have already shown.
EDIT:
Those who say they are having the same issue over WiFi, are you sure the images are not just cached?
Here's a test image which I made. To make this, I opened up the PNG version of my avatar picture (as captured from IE) then saved it as a JPEG file using a quality factor of 20%, then zoomed it 200% using the crudest form of scaling available (i.e. scaling without filtering). This looks not unlike what I'm seeing in Opera and PIE; the question is whether it's the browser that's doing it by itself, or the website.
The block-effect is caused by resampling as a JPEG with very low quality factor. You can see this isn't at all the same kind of artefact as you get simply by reducing the colour depth. It looks to me as though something is resampling the JPEG images when viewed on the HD2. This is what Opera Mobile is supposed to do in Turbo mode, but not when turbo is switched off.

EDIT: And yes, as Syphon Filter says, it could be T-Mobile doing this in my case. I don't have access to wifi at the moment so I can't see if that makes any difference.
Could we get some feedback from people using different carriers as to whether you're seeing the same thing?
Oh, that's interesting: browsing this thread on my HD2 again, and the re-sampling only happens on JPEG images, not PNG's.
EDIT: after clearing out my Opera cache and then connecting via ActiveSync rather than the phone's data connection, I'm now not seeing any compression artefacts on my avatar picture. So this is starting to look like it is T-mobile's fault (although I suppose it could still be Opera sensing whether it is downloading data over 3G or over ActiveSync and changing its behaviour accordingly - it's odd that it seems to make no difference whether I have turbo mode switched on or off in the preferences; but then again, as far as I know there isn't any turbo mode in IE, and I see compression there too).

Yes mate - I've had this same issue with 3 winmo devices now (Touch Diamond, Touch HD & now the HD2).
Should have tried this before: directly saving the JPEG image from Opera rather than trying to use screenshots.
Here's the version that's displayed when browsing over ActiveSync:
And here's the one fetched over the data connection:

No question that there's some JPEG resampling going on.
Opera's risibly poor upscaling algorithm is making things even worse, though!
I am convinced this is an operator data connection issue, it may or may not be being compouned by the poor JPEG rendering/scalings issue of Opera.

I suspect you're right - the fact that the same thing happens in Opera and in IE is suggestive. I can't think how to test for this, though. The images don't get resampled in Skyfire, but that could easily be because T-Mobile doesn't recognise the traffic between Skyfire and the Skyfire server as a JPEG image.
If it is the carrier's fault, is there any way one could conceal from the carrier that one is fetching a JPEG?
