ImMagick

RMagick replacement which uses ImageMagick directly by constructing chainable commands with value placeholders. It basically delegates to the command-line tools, so constructing commands is similar to how you would work with those. The code itself is nothing fancy, it just gets the job done by providing a simple DSL-like construct.

Here are a couple of examples:

cmd = ImMagick::convert.from(:source).resize(:w, :h).grayscale.to('thumbs/thumb-%03d.jpg') cmd.run(:source => 'images/logo.png', :w => 100, :h => 100).save(7) # => thumbs/thumb-007.jpg

img = ImMagick::Image.file('images/logo.png') img.crop_resized(200, 200, :south)

puts img.inspect => "images/logo.png -resize 200x207 -gravity south -crop 200x200+0+0 +repage"

img = ImMagick::Image.file('images/logo.png') img.crop_resized(:w, :h, :g) # width, height, gravity placeholders

puts img.inspect(:w => 200, :h => 300, :g => :south) => "images/logo.png -resize 291x300 -gravity south -crop 200x300+0+0 +repage"

img.save('output/crop-resized-img.jpg', :w => 200, :h => 300, :g => :south)

cmd = ImMagick::convert do |c| c.background(:black) c.fill(:white) c.font('./unionbd.ttf') c.pointsize(40) c.size('300x') c.gravity('west') c.caption(:placeholder) end

puts cmd.inspect(:placeholder => 'FooBar') => "-background black -fill white -font ./unionbd.ttf -pointsize 40 -size 300x -gravity west caption:'FooBar'"

cmd.run(:placeholder => 'FooBar').save('output/foo-bar.png')
