Description: ------------ --- From manual page: http://www.php.net/imagick.tintimage --- comparing the results of convert *input* -fill red -tint 130 *output* with $im->tintImage ("red", 130); The resultant images do not match Test script: --------------- $im = new Imagick ("some_file.jpg"); $im->tintImage ("red", 130); $im->writeImage ("some_file_tinted_red.jpg"); Expected result: ---------------- Image should be tinted red Actual result: -------------- Image is darkened only, as if the value "1" had been given to convert after the -tint command.

Thanks for reporting. This is fixed in master and will be released in 3.4.0RC3 Note. The scale is different for Imagick. On the command line, the normal range for the strength or opacity is 0-100. For Imagick the range is 0-255. i.e. the equivalent of: convert TintTest.png -fill red -tint 40 tint_red.png is: $imagick = new Imagick("./TintTest.png"); $imagick->tintImage ("red", "rgba(102, 102, 102, 1)"); $imagick->setImageFormat('png'); $imagick->writeImage("./TintTest_imagick_40.png"); To use strength values above the normal range, you may need to have ImageMagick compiled with HDRI enabled, as it is possible that pixel colors outside the normal range of 0-255 could be clamped by ImageMagick.
