Cropping image with ImageScience
- by fl00r
ImageScience is cool and light. I am using it in my sinatra app. But I can't understand how can I crop image with not square form and how can I make thumbnail with two dimensions.
As I found on ImageScience site:
ImageScience.with_image(file) do |img|
img.cropped_thumbnail(100) do |thumb|
thumb.save "#{file}_cropped.png"
end
img.thumbnail(100) do |thumb|
thumb.save "#{file}_thumb.png"
end
img.resize(100, 150) do |img2|
img2.save "#{file}_resize.png"
end
end
I can crop thumb and resize thumb only with ONE dimension but I want to use two, as in RMagick. For example I want to crop 100x200px box from image, or I want to make thumbnail with width or height not bigger then 300 (width) or 500 (height) pixels.
