Problem with gradient: IM 7.0.7-37 on Windows 10

Post by GeeMack » 2018-05-31T17:18:18-07:00

Using ImageMagick 7.0.7-37 Q16 x64 HDRI with Windows 10 and running this command...

Code: Select all

magick -size 2000x2000 gradient: gradtest.png
Produces this image...

Image

The top approximately 1% of the image is a gradient from white to black, and everything below that is pure black. This image is 2000x2000, and the gradient covers about the top 20 pixels. If I make the image 100x100, only the top single row will be white, and the remainder of the image is black.

If it's of any help, the same happens in Manjaro Linux. I'm using ImageMagick 7.0.7-37 Q16 x86_64 2018-05-30.
