How do I disable the libpng warning? (python, pyga

问题:

When I run my program it gives me the following warning:

libpng warning: iCCP: known incorrect sRGB profile

I know why this is caused, the sRGB is what it wants, but I use adobe photoshop RGB.

Just wondering if there is any code to disable the warning. It doesn't affect my program. It's just annoying.

Any help would be greatly appreciated!

(Please don't ask me to show my code, my code has nothing to do with this situation)

回答1:

well, you can ignore the warning. I am using ImageMagick for image resizing, and for some png file, the following code will throw exception: iCCP: known incorrect sRGB profile `' @ warning/png.c/MagickPNGWarningHandler/1830

Blob ablob(cont.data(), cont.size()); // cont is the png file content.
Image image;
image.read(ablob);
image.resize( Geometry(100, 100) );

As it says, it's just a warning, you can put the image.read(ablob) in a try{}catch{} block, and ignore the exception. The object image now contains the integrated png data, and can be manipulated correctly.
