MAXIMUM PIC SIZE TEST ON PSP!!!! 56K WARNING!!

Yeah, I was just thinking that what is PSPs maximum image size before something happens. I have managed to make a 32767x32767 image  (posted below) and if someone could test that by saving it to ms0:/PICTURE and see what happens.

Oh: The image cannot be displayed because it contains errors (in properties on the window).


*Froze Nero Photosnap trying to Save/Open it

That's odd. It's supposed to be completely white, because if it would contain even a few colours, it would take 127.9MB instead of 908KB. I couldnt up it to PhotoBucket or anywhere else so my friend lended his bandwith a bit for me. It's made with Paint Shop Pro 7 which's maximum image width height are exactly 32767 pixels.

Re: MAXIMUM PIC SIZE TEST ON PSP!!!! 56K WARNING!!

Anybody know why the maximum width/height is exactly 32767 pixels? Maybe you Jeffy? You told us why the maximum lenght of a post was like 5w436346363 characters big_smile

I used that pic as my avatar today at coolpsp forums...The site doesn't have avatar restrictions. I removed it pretty fast, though. Firefox lagged alot!

32768 = 2^15
Same as the other one, we start counting at 0 and not 1 so it 32767.

32767 is the largest positive integer value that can be formed with 16 bits


I'm pretty sure images could be bigger than that. In theory it could be infinitely big but in practice it's limited to hardware lol.

Who needs a 32767x32767 image anyway?

Well I was thinking if you had a very good computer with 3GHZ CPU and 2GIG RAM, you could also maybe copy-paste a few of these 32000 px images, so you would get bigger one. You might need professional photoediting software or so, because Paint Shop Pros and Photoshop Elements at least get stuck with 32767 pixels.

UPDATE: My friend just IM:d me and told that with Paint Shop Pro he was able to make a pic, which height was 99999 pixels and width 1 pixel, but it was only possible if the picture was in TIFF format. That's odd.

Re: MAXIMUM PIC SIZE TEST ON PSP!!!! 56K WARNING!!

It should be possible to make it a lot bigger. But I guess photo editing software and even your operating system put a limit on that. And for a reason I guess...

Re: MAXIMUM PIC SIZE TEST ON PSP!!!! 56K WARNING!!

Ok, I had my PSP plugged in the PC today (I was making NorPortal VI5ION, which is ready, I'll just upload it) and I tranferred this pic to the PSP and tried to open it but it shows up as "Unsupported Data" Sony has probably tried to fix any buffer overflow exploits, but this might work with lower firmwares causing the PSP to freeze.

Well if you wanted a picture that cover the entire moon, then you'd need a pretty big moniter to view it shocked1
