Subject: imagemagick: expand test.sh coverage
X-Git-Url: http://git.99rst.org/?a=commitdiff_plain;h=b0536d3ff62bdb635ef8cb0d469e6d90004e4cba;p=openwrt-packages.git

imagemagick: expand test.sh coverage

Exercise more of the toolchain on top of the existing PNG/JPEG/BMP,
resize, pixel-sampling, grayscale and composite checks: TIFF round-trip,
PPM and GIF encoders, crop, 90-degree rotate, horizontal append, the IM7
'magick' driver and in-place mogrify.
