Display Image with Pixels 1:1 ? - Nexus 7 (2013) Q&A

I'd like to display some 1920 wide test images such that the pixels map 1:1, how is that possible?

I was having this issue too opening Chrome, searching for 1200x1920 images, then opening the original image but it would never show up 1:1 nor even save as 1:1

Maybe there's a better/easier way but after some brief searching I tried the first app I could find called Perfect Viewer. After playing around a bit I got it to display an image and I found that when you zoom in it will show the scale percentage and snap at 100% to allow 1:1 display. I used it for a gamma test image and it worked fine.

Thanks that worked , bit of a strange app, but for testing 1:1 mapping great solution.

Wallpapers with TouchFlo running

I cannot seem to find the answer to what i have a question on, i see so many cool wallpapers and i dont know how to get them to run on my HD whilst TF is active. Seems I can only get my today screen to reflect the photo i select if i turn OFF touch flo, no good. Support? Thanks
Set the wallpaper via the setting menu on TouchFlo3D rather than the settings for the Today screen.
yes, bt doing so yeilds a low quality picture. any idea how we can set a high resolution pic (800x480) as the background to actually use the screen's full potential?

it is possible but the only way of doing it is a complex hack which is rather time consuming and the results are not perfect. if you would like me to write up the instructions i will do so when i get back on my pc. (browsing on my phone atm) the hack involves inserting pngs into system files and hex edits.
I've created a theme with a high quality wallpaper which you can find here

please help

Hi,
I've recently read a thread which is aimed to show people how to apply backgrounds image for all tabs, but there are several steps that I found quite confusing:
If there is a .png file @ 512x512 resolution,
How can I achieve steps below:
- remove 54 px from top
- remove 50 px from bottom
- increase width by 56 px, you should notice the empty area on the right
- resize the picture to 512x512 px, allow distortion
any help will be gateful!
If there is a .png file @ 512x512 resolution[/QUOTE]
the original image must be at 480x800, otherwise of course 512+56<>512

thanks, but whatever the resolution is, how can i remove or increase pixel of the image from various sides and what tool that i should have picked up for the procedure?
photoshop or gimp

I have Photoshop CS3 installed on my PC, should I use 'image size' option within the 'image' tab to cut pixel?
image size doesn't cut but resizes. better play with canvas size, or by cutting with the crop tool

Thanks, it works for me, but I think I might got something wrong cos the final display on my phone shows a tiny slim line of blank pixel on the right hand side
anyway, I really appreciate your regarding
you have blank pixels since, in my opinion, 56px right is too much. See my tiny tutorial here. It leaves the black hole at top, since i did it b4 the new edit, but the widht is always the same

Optimised Wallpapers

I have put together a collection of wallpapers that are optimised to work with the Galaxy Nexus resolution. I have tried to give some choice and they all look great on my Galaxy Nexus. I have added the original link in the description for those who would like a different crop.
http://imgur.com/a/efWeX/
For those wanting to create their own the images they need to be 1440x1280.
Did not see any existing thread for this. Let me know otherwise.
I was coming here specifically to post on this topic when I noticed your thread.
I don't think 1440x1280 is the optimal size. When you go to select an image as a wallpaper, the selection box is slightly larger than the two rectangles which presumably represent the area that is visible on screen.
With this in mind, it seems as if wallpapers optimised for the Galaxy Nexus should actually be 1440x1280 + some extra black space, so that the actual image squarely fits in the are provided.
Otherwise it would seem that you're taking a 1440x1280 image, cutting off the edges, and then stretching it back up to 1440x1280, resulting in a less clear image (which is a shame on such a gorgeous screen).
Just something I've been wondering about. Feel free to comment or correct me.
Thanks, this is great. Quick question, how would I go about changing the resolution of pictures I already have?
Sorry for my ignorance on this subject.

if your pictures are too small then you DON'T want to change them as they'll just get ruined. upscaling destroys digital images.
your best bet is to just find new wallpapers to use. Luckily for me i've always downloaded 1600x1400+ wallpapers so i'm good.
i am curious though, does the stock wallpaper picture still pixelate the images and ruin gradients? i know my nexus one does that and i downloaded quickpic to get around it. but i have noticed on my tablet wallpapers look good.
If you use something like quickpic it will select the whole image, the built in Gallery app will show you a guide however I find that it does use the whole image at the ratio.
If someone can suggest a better resolution I would appreciate it, otherwise this is the best I have found so far.
I don't have a Nexus (yet), but if someone with root could check the file /data/system/wallpaper_info.xml, there should be a line reading as follows:
<wp width="something" height="something" name="" />

Which should give the actual expected resolution.

You can drag the edges of the box to make it bigger - there still seem to be corners left out but I was able to get the top / bottom / side edges of the selected area out to the edges of my image.
I made a couple of darkish fractals at 1440 x 1280, in an attempt to extend battery life without going entirely black.

Thanks! So that should mean it does include the 96px soft-button area (also meaning the lower 96px of the wallpaper will not be visible). As soon as VZW decides to launch the damn thing I'll give it some testing, but I'm pretty confident the 1440 x 1280 is correct.
Just thought I'd report back with my experiences.
I've been making some wallpapers and experimenting over the last few days, and I'm very confident that the correct wallpaper size is 1440x1184 ie. you have to remove the 96 pixels taken up by the soft buttons to get things to work nicely.
If you use this size wallpaper, the selection box will be completely filled, without leaving out any parts.
yeap

Someone may be able to assist me here, but my absolute most HATED part of Android is the wallpaper selector. I can never actually set a picture I want as wallpaper because of the poxy blue line crop/selector which refuses to actually ever take in the full image.
I've used photoshop to resize a photo to the dimensions for the screen and it's still too big for the photo selector. Am I missing something very elementary here??
**EDIT**
I just made an image which was 100 pixels high as an acid test and when i tried to set IT was wallpaper it was tiny and shrunk, but so was the selector box and I STILL couldn't select the whole image. What the heck am I doing wrong!??

Have you tried 1440 x 1184 as a size? Then if it doesn't select the whole thing first time try dragging the edges of the box.

I'd love to see some from these. I also wish for a NASA respository.
Okay, now that I actually HAVE a Nexus, I can say with certainty that 1440 x 1280 (not 1184) is the correct wallpaper resolution. 1440 x 1184 is not the same aspect ratio as the crop box; however, you can add 96 blank pixels along the bottom of a 1440 x 1184 image (making it 1440 x 1280) and it fills the crop box, and the bottom 96 pixels don't show on the home screen due to the software buttons.
Would post a preview pic, but I need to post more first, I guess

[Q] Samsung TabPro 10.1 Resolutions & Laggs

Hey!
I received my tabpro and i notice so much lag in games like simpsons tapped out. My girlfriend has Tab 3 and it runns perfectly. Is it about the resolutions, since i have 2560x1600. Is there any way to lower my resolution or do I have to install custom ROM.
And why my homescreen resolution is not that 2560x1600. My image is 2560x1600 and it looks nice in gallery but after i use it as my wallpaper on homescreen it gets blurry.
I thought this tablet is powerfull in games and so on. But i am very disappointed. All help is needed so help me to to get clean rom or just help to lower my resolutions.
Any suggestions?
I'd like to know this aswell.

It should be possible to change the resolution of an app with "app settings", an XPosed Framework module. (root required)
When you set an image as your wallpaper it gets zoomed in (as it has to fit screen and scroll horizontal), therfore, the pixels of the image won't match pixels on the screen anymore and get re-calculated, making the picture blurry.

2560x1600 wallpapers in portrait orientation?

Anyone recommend where I can find 2560x1600 wallpapers in portrait mode? Easy to find in landscape, but that doesn't fully make use of the 8.4 resolution (since its cropped). If I use a landscape image, whats the minimum resolution image I need to maintain a 2560x1600 cropped image? So far the link below are the only photos I found in portrait 2560x1600:
http://regex.info/blog/2010-11-28/1671
I tried Chainfires 500 Firepaper app, but gave up. It doesn't let me save the images since the photos don't belong to him/his app (barrowed from 500PX).
try 4walled don't know the exact resolution you should go for, though.
edit: try 2560 x 3200
