Some graphic "Transparency" problem after recompile

#1

Hi to all,
i have recompiled whole Frogatto, on MAC OS X 10.6.6, afer a CLEAN SVN Download, but i have strange transparency problem on some graphics;
Seems that the problem is related to some PNGs images transparency color index number?? PNG Supports?? or what??
Please let me know what’s wrong!!

I have used as SDL’s Frameworks:
SDL 1.2.14
SDL image-1.2.10
SDL mixer-1.2.11
SDL ttf-2.0.10

#2

Can be a kind of PNG support that, for some case, has been disabled?

Resolved!
Talking with Crimson_Penguin on the Mirc, we understand that the problem is the SDL_IMAGE version.
Infact i have used the latest one 1.2.10 but in the official release of Frogatto is used the 1.2.6
So using the SDL_IMAGE 1.2.6 all works correctly.
Other SDL stuff (main SDL, mixer and ttf) the latest releases are OK!
I suppose that Crimson_Penguin + Sirp (and other Frogatto’s Stuff) will works to understand that … no?? :slight_smile:

The curious thing is that in the latest 4 release (prior to the one used in the official) there are many fixes particularly for the MAC OS X.
I paste the latest 3 releases changelog:

1.2.10:

  • Fixed bug loading multiple images

1.2.9:

  • Fixed alpha premultiplication on Mac OS X and iPhone OS
  • Fixed checking for IMG_Init() return value in image loaders

1.2.8:

  • Added support for uncompressed PCX files
  • Added IMG_Init()/IMG_Quit() to prevent constantly loading and unloading DLLs
  • Added support for ICO and CUR image files
  • Added ImageIO loading infrastructure for Mac OS X
  • Added UIImage loading infrastructure for iPhone / iPod Touch

Thanks and Bye to all

Hi to all again …
i check also with SDL_Image 1.2.7 and works correctly too!
The problem there is when use version =>1.2.8

so, i suppose, that one of these features/fix is the problem …

1.2.8:

  • Added support for uncompressed PCX files
  • Added IMG_Init()/IMG_Quit() to prevent constantly loading and unloading DLLs
  • Added support for ICO and CUR image files
  • Added ImageIO loading infrastructure for Mac OS X
  • Added UIImage loading infrastructure for iPhone / iPod Touch

What you think about??
See later …

After Jetrel remove correctly the ICC Profile from Font Sheet image, finally we solved the problem.
The problem is then, as Crimson_Penguin tells initially, the Profile managed by new sdl_image version that shift the colors then the transparency color.
Thanks to all!!

Image with only update Font Sheet image (need now to fix all the other images).

ONE MAN TOPIC! :smiley:

Problem completely solved using simple the wonderful ImageMagick.
After different attemps i found in the command-line “-strip” the solution.
The command “-strip” can be used both for Convert and Mogrify
i use Mogrify to change directly the original image.
so …

mogrify -strip *.png

I convert all images and tested with SDL_image 1.2.10 and all is OK!
Now if anyone of the Frogatto’s Staff wanna do this and put on SVN (sure … if this is considered necessary!)
See later…

I didn’t have ImageMagick installed anymore since upgrading my OS, so instead I turned to the OS-included “sips”, and wrote this little one-liner to remove profiles only from images that have them (and thereby not mark everything as changed and have to upload it again):

Crimson_Penguin, the script works perfectly too!
