Qt ：libpng warning: iCCP: known incorrect sRGB profile警告信息之解决方法

1、从ImageMagick的官网下载压缩包，地址： http://www.imagemagick.org/script/binary-releases.PHP

根据平台下载相对应的压缩包，如Windows下载ImageMagick-7.0.4-0-portable-Q16-x64.zip

2、把下载完的压缩包解压到e:/Programs/ImageMagick

3、在Qt的资源文件夹下（Qt调用资源的目录）新建 ImageMagick-Fix-PNG.bat 文件

打开后编辑内容：

@echo off
echo ImageMagick fix libpng warning: iCCP: Not recognizing known sRGB profile ......
echo Search PNG in subdirs and process ...
set fn=E:\Programs\ImageMagick\convert.exe
for /f "tokens=*" %%i in ('dir/s/b *.png') do "%fn%" "%%i" -strip "%%i"
pause

4、保存，单击打开，警告消除！
