Rescomp problem

Hi,
I'm having a few issues with rescomp at the moment.
If I want to use the SPRITE function in my gfx.res file, like so:
Code: Select all
IMAGE gamelogo "res/logo2.png" -1
IMAGE bgcity "res/city.png" -1
SPRITE flappy_sprite "res/flapspr2.bmp" 6 6 -1 5
(including an empty line on the end)
I get the following error:
Code: Select all
Packed with APLIB, original size = 3456 compressed to 452 (13.0787 %)
Resource: SPRITE flappy_sprite "res/flapspr2.bmp" 6 6 -1 5
--> executing plugin SPRITE...
Error: Image res/flapspr2.bmp use color index >= 64
IMAGE resource require image with a maximum of 64 colors.
make: *** [gfx.s] Error 1
rm gfx.s
Process terminated with status 2 (0 minute(s), 0 second(s))
0 error(s), 0 warning(s) (0 minute(s), 0 second(s))
I did check the amount of colors, and i'm using the same palette as I use in logo2.png and city.png.
I tried using both .bmp and .png files.
This is the palette i'm using:
I even tried using the "remove unused colors" function in mtPaint, but when I save it then, rescomp just crashes...
Any ideas?
Thanks in advance!

Indeed that should work. Is it possible to post a link of your image somewhere ? I would like to understand why rescomp is complaining.
Also the rescomp crash is not expected as well, it would be nice to have all the problematic images so i can fix it
rescomp currently only support 4bpp or 8bpp BMP or PNG images but i guess that is the format you are using.

Try to up your palette entries to 256 that should works

Hi Stef,
Here you go:
BMP version -
PNG version
The BMP version will raise that error, and with the PNG version, rescomp just crashes...

Oh, and this is what i get when trying to compile using a .png file:
Code: Select all
compressed 2455 -> 277 bytes (71% done)
compressed 3456 -> 452 bytes (100% done)
compressed 3456 -> 452 bytes (13%) in 0.00 seconds
make: *** [gfx.s] Error 255
rm gfx.s
Process terminated with status 2 (1 minute(s), 6 second(s))
0 error(s), 0 warning(s) (1 minute(s), 6 second(s))

I think i might have found the problem.
Normally, i use Photoshop with a Genesis palette to create my images. Then i save it to PNG, open it in mtPaint to tweak it (the palette, etc) and save it again.
However, if you save it using compression, it'll raise the error and/or crash.
I just saved it without compression, opened it in mtPaint, resaved it with the right palette, and now it works

Ok, i was just trying to find out the issue with the BMP file and i discovered that the file does indeed contains a single pixel with value set to 0xD0 (file offset = 101503) so it explains why the file did not worked ! I guess one of the tool used to save the file had corrupted it...
I will check the PNG file now, as even compressed it should not crash :-/
Edit: Oh the PNG had the same issue ! a single pixel set to 0xD0, same address... oh weird as again the header file reference a 16 entry palette only. It looks like you used a software which generate corrupted images :-/
I also fixed a very stupid issue in rescomp with empty animation detection
I will upload it soon (directly on SVN).

I should note that I created a whole new PNG file, so it's possible that the PNG I created earlier might contain that same pixel.

Probably Photoshop then. It kind of sucks for pixeling. :p

Stef,
This might be a dumb question, but is there a way i can "fix" those broken PNG's?
I tried copying part of the content to a new PNG file, but it keeps giving me issues.
Or do i have to recreate the whole sprite sheet?
Thanks in advance!

Actually i used gimp to edit it, just converted to RGB then back to indexed mode, saved and it's done. Final image was ok.
But you should use the last version i uploaded as i fixed an issue with empty sprite detection (which was giving error with your images).

Stef,
The new Rescomp version works perfectly
Here's the result. The bird sprite is of course animated
