无法在Windows环境中将带Imagemagick的图像与机器人框架进行比较 [英] Failed to compare images with Imagemagick with robot framework on Windows environment
问题描述
我正在使用Imagemagick来比较Windows环境中的两个屏幕截图。
或者,使用以下新命令:
magick输入.png ... output.png
而不是:
convert input.png ... output.png
所以,如果您知道如何将配置变量 IMAGE_COMPARATOR_COMMAND
更改为 C:\\程序文件\\ ImageMagick -7.0.7-Q16 \\magick
,你可以不用重新进行拖延ImageMagick。
I am using Imagemagick to compare two screenshots in windows environment.

If you want to use the "legacy" convert
command with ImageMagick v7, you need to click the option during installation of ImageMagick that says "Install legacy tools".
Or, use the new command which is:
magick input.png ... output.png
rather than:
convert input.png ... output.png
So, if you know how to change your configuration variable IMAGE_COMPARATOR_COMMAND
to C:\\"Program File"\\ImageMagick-7.0.7-Q16\\magick
, you can do it without re-installing ImageMagick.
