Hey guys! Ill try to make myself clear ! Im encountering the following issue:
whenever im trying to use an image as a wallpaper for htc sense it`s been displayed somehow blurry (i guess it doesnt have anything to do with the transparency settings) .
I`ve tried to use the same image for lock screen and sense screen. The result is that in lock screen it looks very sharp and in sense screen its blurry!
Any ideas ?
What dimensions do you use? I noticed the animated ones are 480 x 696...
i didnt care much about the resolution ... i just used to download wallpapers and use them! Eventually, i tried to crop the images to 800/480 but that didnt seem to be a solution!
Are you trying to say that its something similar to that "contact pics thumbnails problem" ?
On a second thought, im encountering the same problem even if i use the stock set of images ! Another thing is that if im using the default ANIMATED wallpapers things seem to be ok ! So the problem occurs only when im using the "weather wallpaper"
Well, if the picture is anything else than the required dimensions (the word "resolution" is actually inaccurate), the system will try to either shrink or magnify it, a process which can cause various artifacts, including the blurry effect you are describing.
I would try an image with the dimensions I quoted in my previous post to see if that looks all right.
thanks! im gonna try now and tell you the result
nothing new ! Still the same problem! Wallpapers in lock mode are displayed correctly, the ones in weather mode are blurry!
Strange... I may try it myself this evening if I have the time.
*update* ... aften another day of "testing" i guess its all because HTC sense. Ive installed SPB mobile shell and things are ok there, so, luckily its not a problem with the display!
It's because HTC Sense compresses the wallpaper into this random format and stores it somewhere...
umm ... and what should i do about it ?
I started to get very annoyed with this problem.
When I use opera, and enter a web page with lots of images (eg. lifehacker.com), I can't seem to zoom in enough to have clear, NON-choppy, images. It seems like the more I zoom pass the double-tap, images just gets worse and more pixellated.
Is there something I am doing wrong? Is there a fix to this?
I've applied the tweak where I can see whole webpages instead of "zoomed-in" versions that came stock.
Don't know if this is the problem causer.
AFAIK, double-tap sets "zoom level" to 100% (1 image pixel= 1 screen pixel), any more is enlarging and inevitably leading to choppy images.
EDIT: Actually, double-tap seems to already be more than 100%, a 200pix wide image on my gallery is rendered as 350 pixels on screen after a double-tap.
hi guys, when i goto crop my pics, they crop fine, but im left with a tiny picture..
how do i resize the pic to full screen...
this is one of the biggest problems about the x10,i have loads of pictures but most come out all small or fuzzy using the crop,why se didnt just allow full screen wallpaper is beyond me,however there are a few apps in the store that allows full screen wallpapers however must force close a lot and piece of advice dont use justpics it freezes the phone completely i learned it the hard way,if you find a better way to use full pics as wallpaper please let me know thanks
Bloody JOKING...
Yeah it seems there's some seriously dumbass software issues with the wallpaper option on the X10.
It seems there is no straight forward to way to simply select picture (either one you've take or one upload from cpu/bluetooth) and set the whole/full image as phone's background.
Cropping is forced and as far as i can tell MAX image is 2 THIRDS OF SCREEN!!
Ok this is kinda bugging the me to no end. Nothing is WRONG with the screen, as this only appears in certain places.
Here's what I mean: When I start up settings, or anything that darkens the background, you can see these lines: http://imgur.com/eCELgov,yPD8mMK#0 in the first image. You would also see ripples only around the jelly beans, but you can only see it in the ES Image Viewer window in the Recent Apps. But when I go back to my homescreen, the lines disappear. And this only happens with certain parts of apps or the settings, as I changed my brightness down to low as possible, and no lines or ripples.
I'm on Rastakat 4.4.2, and this is a recently bought tablet which has been working fine so far.
EDIT: This is probably a way better example: https://www.dropbox.com/s/a3r7gz5wjlwvq92/Screenshot_2014-01-01-17-30-16.png

Hi, Duskye...
It's always tricky judging these things from a screenshot... but it looks like you have light bleed due to screen lift on the right hand side of the screen.
I have a little light bleed myself on my Nexus 7, though nowhere near as bad as yours. I've taken the back of my Nexus 7, and I've noticed a screw is missing that should clamp the screen tightly to the frame, and thus allowing light to bleed from underneath. It's never really been a major issue for me, as it's only really noticable when the screen is really dark.
If, as you say, your device is new, I wouldn't waste time in trying to fix it yourself... you should get a refund/repair or replacement.
Also, if you have bad screen lift, the screen itself can be prone to easy cracking/shattering as it's not tightly clamped in the frame.
Screen lift/light bleed issues where a significant problem last year (I mean 2012, I forget, it's 2014 now) when the first batches of the N7 came out... but I thought those early production problems had now been ironed out.
One thing you could try... purely as diagnostic... is download from Google Playstore any one of the many testcard apps. They run the screen through a variety of coloured background's... including black... if there is no uniformity across the screen in black, then it's almost certainly screen lift. And you have a hardware problem.
And if this is the case, you should seek redress under warranty.
Good luck.
Rgrds,
Ged.
This happens on _all_ parts of the screen, it's not just that side, and, like I said, this only happens in certain parts, like say if the jellybean wallpaper had jellybeans falling from the top, I would only see those ripples _on_ the jelly beans, and the ripples move along with the jellybeans if they were in any other postion, and no where else. And I should probably mention this: This was not apparent when I had 4.1 on this. This only started happening when I installed Kitkat.
And this is probably me being uninformed, but if this a hardware problem, then how come you are able to see the problems from a screenshot it took from the device itself?
I don't think there is anything wrong with your screen. You are seeing quantization artifacts due to the "dimming". The degree to which you observe this depends on the original image.
For instance, look at your screen on Settings...Display.
All those subtle horizontal bands at the bottom of the screen are not intentional, but due to the fact that a "gradient" painted with a limited number of values will show intensity steps at each value transition, so long as your eyes can resolve that intensity difference. And this effect is always most pronounced at low intensity values.
For instance, "grey" values always have equal R,G, and B intensities, e.g.:
RGB
000 = black
111 = grey1
222 = grey2
...
254,254,254 = grey254
255,255,255 = white
So for instance the "intensity" difference between grey3 and grey4 is
I(grey3) = sqrt(3^2 + 3^2 + 3^2) = 5.196
I(grey4) = sqrt(4^2 + 4^2 + 4^2) = 6.928
(6.928 - 5.196)/5.196 * 100 = 33%
whereas the difference in observed intensity between grey240 and grey 241 is only 0.42%
You won't notice quantization effects in bright images, but you will when the same image is dim.
@Duskye Is this a live wallpaper we are talking about? There are lots of (ahem) "optimizations" that can be made (for instance sub-sampling) which sacrifice image quality for speed, so it is reasonable to believe that a software update could change things. Did you fool with any of the rendering or live wallpaper options in Settings... Developer Options?
PS Ged: When someone takes a "screenshot", they are not literally taking a picture of the screen, but dumping color values from a framebuffer. So it is not possible to capture "bleed" with a screenshot; you would have to use an actual camera for that.
Nope, that's just the regular default jellybean wallpaper, though it does this with any wallpaper.
And the only dev options I touched were USB Debugging, nothing else.
EDIT: I installed Carbon, which latest release is Jelly Bean, and the lines are not as apparent, in fact they're all gone from settings, there isn't even any ripples anymore.
EDIT2: I took a photo with Carbon as well, and made a side by side of the Rastakat and Carbon pictures: http://i.imgur.com/bk6ElGq.png

Well, there you have it - it's not hardware.
There are other possibilities as well - .JPG image files are partial DCTs (Discrete Cosine Transformations) on 8x8 pixel blocks. They are "partial" in the sense that compression is achieved by dropping high-frequency coefficients of the transform in each block. While all of this is standardized in the JPG format, there is no reason why a rendering method needs to compute the full image for display using all the coefficients - in the name of rendering speed. Similarly, when you "assign" the wallpaper, I believe the source file is copied to a standard location. It is possible that it is also down-sampled at that point in time, esp. if the original image was stored as a high-quality JPG image file (little to no compression).
Anyway, you get the idea - any or all of this can be affected by the ROM build.
Hi everyone
I reduced the resolution to 1080p using adb everything works well except of 2 things
Screenshots which is not full screen just part of it is being captured
And app switcher is showing a part of the thumbnail of the app like it's zoomed in for the upper left part of the app.
Is there anything i could do to slove this problem?
