Lockscreen wallpaper... again

Hi,
I've been playing around transferring files onto my phone, but I just can't get my lock screen to look right.
1. Does anyone know what the exact dimensions of the lockscreen image should be? I read 320x480 somewhere, but this isn't correct. I've also tried 360x380, 340x480. Maybe it's 345x480? I want to get this right because...
2. Whenever I set an image onto the lock screen, the phone seems to compress the image really badly and I see loads of jpg artifacts on the parts that should be solid colour. I'm hoping that if the image is the right size, it won't convert/re-sample/re-compress the file.
Any ideas?

The stock ones are 320 x 455, and I've had good results using those dimensions for my own images.

Im sure i read that converting your image to a png and using that instead of the png file gave better results also. Not 100% on that though lol

.png gives better quality than jpg.

320x455 px is the right size. But everytime you set wallpaper, HTC software it re-compress as JPEG in tragical quality. PNG or JPEG, that makes no difference.
Will be nice software like Wallpaper Set & Save for lock screen wallpaper. But I can't find something like that.

Not my experience. My own images are usually desktop 'papers resized and/or cropped to 320x455 and saved as JPEGs, and provided I ensure the green 'crop box' is expanded to encompass the entire image when selecting the lockscreen they look just as good as the originals.

I've tried many images. At most (as you) cropped or resized desktop wallpapers. I prepare the correct size and copy to phone. I keep JPEG at 90 to 100% of quality and also convert it to PNG. And every image was resampled during setting up as lock screen wallpaper. Everytime its quality goes rapidly down. Even I used exactly the same way like you.
It is not good visible on landscape wallpapers with. But on artifical images it's very big problem. It blurs every contrast line on image.

Here you go.... see what you think. View attachment lockscreen.zip
Not perfect, but it was a rush job. Resized from 1280x1024 to ???x455, then cropped to 320x455. Saved as JPEG @ 100% for use. Photoshop Elements 7 used. If I had more time I'd probably play with the sharpening to compensate for the downsizing.

Also having this issue with this image..

I have problems with all images. But on this it's good visible. And as Shluggity's screenshots shows, it's not only my problem. I think it's not good

I'm not sure what's going on but there's definitely some sort of degradation visible, a softening of the edges. I honestly haven't seen it in my own wallpapers, but I haven't used images like this with lots of thin sharp 'light beam' effects. Maybe original image res is a factor, maybe screen dpi, maybe something completely different... If I have time tomorrow I'll do some tests.

how does wallpaper set and save work? maybe the wallpaper directory is similar to the lockscreen directory?

Have you tried HeroLockWall? (Market)

sadly this seems to be the only way to have high quality wallpapers on the hero... the app works fine, but the wp has to be reapplied after every reboot...

You can put them in Rosie.apk with Metamorph, then they are crisp and fine.

well, as rightfood thaught us you can put them in your sense app file. but that needs a rooted phone and is "hacking" to some degree, so actually wp s&s would be the more "regular" way. and yes, it is sad that there is the need for third party apps, but that's the way it is...

oh,.. i dont want to root my phone yet... :\

lag delete please

hum i found a strange thing...
i downloaded that "Backgrounds" app available on market and when i apply a background with the app the background doenst loose quality...
but if i download that same background from "Backgrounds" app and apply it manually...the background looses quality again...
what a weird thing... err

i use backgrounds and wallpaper plus available from market
work fine for me

Please try with some more higher resolutions other than 72 dpi.
The official HTC Hero page says this:
"Display: 3.2-inch TFT-LCD touch-sensitive screen with 320x480 HVGA resolution"
Which means the correct dimensions are 480x320.
Since it's HVGA, so you need to experiment with some more resolutions to try out which one is best...
And do let us know...

erm, no.
that would end up with the picture being not only pixelated, but stretched as well. the display is 480 pixels high, so creating a wallpaper that is 320 pixels high would just chuff everything up.
The wallpaper changes slightly as you go from one homescreen to the next, as it is actual;ly LARGER than the screen. The general rule is 640x480 (yes it should be landscape, even though the screen is portrait), and from what i think i read in other places, you should use PNG files and not JPG files for the background.
but creating a 480*320 file to use as background will just make things worse.
But yeah, i think using the higher DPI in the wallpaper is something to look at.

Wallpaper question

All,
Where should I put my images that I would like to use for wallpapers? Even with the stock images, I noticed that depending on what menu I used to set the wallpaper, some were resized strangely.

Thanks!

where you put them shouldn't impact the image size. you can put wallpaper images anywhere really. i put them in /media/wallpaper on my sdcard.

I tried saving images from websites using the built in browser and then set them as wallpaper, but that didn't work.
I downloaded Opera Mini from the market and then I could properly save images and set them as wallpaper.
Maybe there is a setting for the native browser that allows for proper saving, but I could not find it. Anyway, Opera is a pretty decent bowser so I'm perfectly happy using it.

Thanks for the tip. But, I'm trying to use my own pictures - not web images.

1200x1024 is the proper size for two screens. 1800x1024 for 3. you could try resizing before setting as wallpaper to see if that works for ya. make sure you expand the box to take up the entire image when selecting it or it will mess up the sizing.

Thanks. Happen to know the right size for 1 screen? is it 600 x 1024? (seems to be if my math is correct)
But, what I'm more curious about is where to put the files. Seems there is a /media/wallpaper on my sd and my internal. Which should I use? I want it to show up in my "wallpaper".
Also, happen to know if it is safe to delete the stock pictures / wallpapers. Some of them are downright ugly.
Thanks!

don't know about deleting the stock images. you could try... i doubt it'd hurt anything, but just to be safe, make sure you nandroid first.
ya... i've never done a single screen, but that is the right math... 600 per screen.
either place will work. i've loaded them in both locations and they work in either.

I had the same problem, solution is to download coveroid. Any wallpaper you want will just go into the coveroid download folder, and then set the wallpaper from inside coveroid. For some reason the non-default launchers cause issues with setting wallpapers, but coveroid seems to fix this.

1200x1024 is the correct size for 5 pages. When you slide from one page to another the background doesn't move by full 600 pixels. It only moves by 150 pixels.
The built-in gallery function scales the pictures in an ugly way when cropping for use as wallpaper. It's a conflict between 3 screens of the B&N Nook and 5 screens of the typical Android launcher.
I followed the sticky with tips and downloaded the Wallpaper Set & Save app. It lets you navigate for pictures through directories and sets them as wallpaper while preserving the resolution if correct to begin with. I'm very pleased with it. My wallpaper now looks correct.

Thanks for the help!
I hope to have some cool wallpapers soon. It helps to have a Pro photographer in the family.

[Q] Removing aspect constraints for wallpapers?

Hey guys. For a while I was using a wallpaper that was actually two wallpapers, half on one side half on the other side, and 2 homescreens. What this did was let me have a "different" wallpaper for each homescreen.
I am completely redoing my homescreens with widgets and to make it overal more informational/functional. I will now have a total of 4 screens, I might stick to 3 screens if I get rid of my calender/agenda widget.
The problem I'm having is when I make a wallpaper with 3 or 4 images of the same size as the screen, when I go to set it, it forces me to select an area based on that aspect ratio... I want to get rid of it, so I can use a wallpaper that's 3 or 4 "screens" wide, and use 3 or 4 homescreens. That way when I scroll over screens it has a different background.
Is this possible? with either forcing the picture manually somewhere? or with an app of some sort?
Thanks in advanced for any input!

You just need to shrink the image down to the right size.

Thats the point... I don't want to have to make it the aspect ratio it wants me to. I have a picture the size I want, but when I want to use it, it cuts off extra on the side that I put there on purpose in an effort to make it appear that I have a different wallpaper for each homescreen.

Its not the size that you want if its cutting off the sides.... lets toss some logic into this.
There is a live wallpaper that does what your looking for, its called multi live wallpaper or something similar to that.

How do you know what size I want. I'm telling you what size I want. And I want it for a reason. Try reading through both my posts.. I can't see how o can dumb up my goal any more that what it is...

I've already told you what you need to do. Use it or don't, I don't care.

I believe Android limits the maximum resolution to 2x width of screen resolution. I'm not sure as I have no experience with other screen sizes and Android. Increase would require some depth of code manipulation that may result in more RAM use than would be practical.
I'm talking out of my ass here, but really, if Google thought the idea would have been practical, they probably would have implemented it to begin with, or in one of the many updates Android has had.
Maybe request the author of whatever 3rd party launcher you like make it an option. I'm sure the launcher programs can be written at the very least to place images over the home screen.

MultiPicture Live Wallpaper
This will allow you to have a different picture for each screen.

You could also try something like Flikie. I am not sure if it will manage images greater than 960x800 in resolution. Never tried it. Might be worth a shot

Went with the Live Wallpaper thing. Thanks for that input!

HOW TO apply a 1024x600 hd wallpaper

this will blow your mind on how crystal clear the wallpapers can be when we use native 1024x600 resolution. this is not some blown up 480x800 blurry wallpapers we always see to acheve wallpaper scrolling wich I always have off cus it lags my scrolling

enjoy the most unreal wallpaper on your nook. if u have adw select landscape oreintation only . because potrait kills the wallpaper

Or just check the long-standing steps posted in the OP of a stickied thread in this very forum There is a quick & dirty solution there, but also my steps to get a pixel-perfect wallpaper.
http://forum.xda-developers.com/showthread.php?t=889951
PS: 1024x600 is too small. You need a bigger image than that if you want to have it move in the background a keep an un-stretched image. We use the same size as the Galaxy, which is 1200x1024. That seems to give me the best results.

that method involves cropping the picture. my method SHOWS THE WHOLE 1024x600 picture (no croping)and its a tottaly diffrent way of the one that's posted on there. and I also mentioned I dont like having the wallpaper scroll at a cost of performance. if u wanna do it your way by all means I'm just sharing my way of doing things. cheers

Well you only need to crop the image if it's not the right size already, which is true of any method of setting a wallpaper, including yours. Not to mention that your method breaks in 50% of supported orientations Hardly "tottaly diffrent..."
And I have no idea what performance hit you are seeing from having a scrolling wallpaper. I've had no issues at all on Android 2.1 or 2.3, both at stock or with an OC'ed kernal. I mean, you're of course welcome to use whatever settings you want, I just dont know what performance hit you're talking about.
Either way, this just seems like a bunch of extra steps to accomplish the same thing that has been posted previously, just with less functionality. I dont mean to sound malicious; I just dont understand what advantage you're offering people.

wow I have to spoon feed u an understanding of what i acheved. read and read again. u get a 1024x600 native wallpaper on your nook on landscape. no chopping or visible blockyness. if u want a wallpaper that scrolls your method is prob good I never tryed it. but since I DO NOT have my wallpaper scroll I like to have the WHOLE picture visible and none of it hiding on the sides

Thank you so much
You are a genius cowballz69!!! Not only did this solve my problem and keep me from having to crop, resize, etc, etc, it also allowed me to have random wallpapers, different size wallpapers, etc. And they all scale excellently and look wonderful on my Nook Color! I was even able to mess around with the program settings and get an accpetable workaround for the wallpapers in portrait mode. (I have the mirror effect above and below the image, looks nice.) Thanks again!

Is this 1-1 pixel mapping when done either way?
I haven't even tried putting a wallpaper on other than the defaults yet, too busy exploring other NC features.

I tried every single method out there, this was the only one that really came out nice and crisp. Thanks man.
After reading up, i also tried ES File Explorer's Wallpaper function and got very good results, not as good as your method, but i would prefer to not run a live wallpaper if possible and got good results. I hope a surefire solution to this wallpaper situation shows up for the nook one day. I force the nook to landscape btw.

I just tried Wall Switch with 1024x600 wallpapers and it still insists on cropping and otherwise adjusting the pics.
edit:
On the subject of the thread, I'm kind of surprised that this hasn't been fixed yet. Usually you guys jump on wallpapers and themes right after root.
I don't understand why the settings aren't built in that will allow us to just go choose a 1024x600 image, apply it in the correct orientation, and not let it move no matter how the screen is tilted. I don't want my wallpaper to scroll or change at all. That seems like it should be easy to do.
