fixing 'libpng warning: iCCP: known incorrect sRGB profile' appears in Pygame.

Libpng warning: iCCP: known incorrect sRGB profile.

Some .png images used in pygame may get the warning read as "libpng warning: iCCP: known incorrect sRGB profile". To solve this I have searched and found the solution by using ImageMagick. After installing, single file can be fixed by calling convert <in_img> -strip <out_img>, but to make it fixes every wanted images in path we'll need to modify just a little bit.

Create .bat file contains the following code and place this .bat in the folder that want to be fixed and run to finish it out.

@echo off
ping -n 2 127.0.0.1 > nul

echo this batch will convert ".png" using -strip option from ImageMagick.
echo please make sure you place a batch file in the right location.

ping -n 1 127.0.0.1 > nul

for %%i in (*.png) do identify %%i
for %%i in (*.png) do convert %%i -strip %%i
for %%i in (*.png) do identify %%i

echo finish..

ping -n 2 127.0.0.1 > nul
set /P user_input=Press any key to terminate...

Thanks.I didn't install ImageMagick. After running .bat in the working environment and pressing Enter, there is no Libpng warning: iCCP: illustrates incorrect sRGB profile.

Make sure when you're installing ImageMagick to select "Install Legacy Utilities (eg. convert)
and it will work!

What should we write in the command line to run the file? Sorry if this sounds silly but I have never worked with .bat before

I use GIMP to fix this problem. Open the image that is causing the problem. Then go to Image -> Mode -> Assign Colour Profile, and chose RGB Workspace. And export the "new" image.
