copied!<p>A few thoughts and some code. </p> <p>What differences do you see? How can you tell it's width first? I don't see a case where the end result should be a different size, if it's a quality problem an example might help.</p> <p>It doesn't look like the api exposes a way to stretch one way and then another but we can certainly make a method or two to give it a try. There are two approaches below, the first, <strong>two_step_resize</strong> resizes in one direction and the the other. The second, <strong>resize_with_rotate</strong> rotates the image, resizes it, and then rotates it back. </p> <p>For the examples I ran it through I don't see any oddness in either solution. </p> <pre><code>require 'RMagick' #Change the size in two steps, height first then width def two_step_resize(img, filename, max_x, max_y) x = img.columns y = img.rows #make sure it's a float w/ the 1.0* ratio = (1.0*x)/y new_y = max_y new_x = ratio * new_y if (new_x > max_x) new_x = max_x new_y = new_x / ratio end # do the change in two steps, first the height img.resize!(x, new_y); #then the width img.resize!(new_x, new_y) #save it, with the least compression to get a better image res.write(filename){self.quality=100} end #spin the image before resizing def resize_with_rotate(img, output_filename, max_x, max_y) res = img.rotate(90).resize_to_fit(max_y, max_x).rotate(-90) res.write(output_filename){self.quality=100} end img = Magick::Image.read(filename).first two_step_resize(img, "2-step.jpg", 100, 200) img = Magick::Image.read(filename).first resize_with_rotate(img, "rotate.jpg", 100, 200) </code></pre>
