I believe the description for imagick::COMPOSITE_MINUS is incorrect. It states:



"Subtracts the source from the target"



But according to ImageMagick's documentation:



"The original method name 'Minus' is a synonym for 'Minus_Dst' meaning 'minus the destination'"



And defines "Minus_Dst" as:

"Src - Dest"



So the description of "imagick::COMPOSITE_MINUS" should be "Subtracts the target from the source"

The `COLOR_OPACITY` doesn't exist if you are using ImageMagick lib 7 or newer version!



Here is the c source code:



#if MagickLibVersion < 0x700

    IMAGICK_REGISTER_CONST_LONG("COLOR_OPACITY", PHP_IMAGICK_COLOR_OPACITY);

#endif



There isn't any information about it anywhere (or I didn't find it)! So, if you want to use it, use the 6 version of lib! You can see the current installed version of lib with this command:



$ identify -version
