Image Resizing Grows Up (or Down)

Rsizr is a new, Flash based image processing site that does just one thing - it resizes an image. However, as well as allowing you to select the standard, lossy resizing algorythm it also offers the ability to use a new one called “seam carving”. Seam carving analyses the image content and divides it into slices of interesting and uninteresting bits. If you're reducing the size, it can remove uninteresting sections and keep the detailed bits intact and. vice versa, if enlarging, then it can insert slices that match the colour and texture of the surrounding area. For example, the follwoing image is followed by one I reduced vertically using the new algorythm…



It's pretty obvious that the process used above has removed a lot of the flat areas from the background and left the detail. Another nice touch is the ability to paint over an area and either preserve or remove it during the operation, which means you get to decide what is and what isn't interesting.

Rsizr can process JPEG, GIF or PNG images and save as JPEG or PNG. It doesn't allow you to load images from photo sharing sites like a lot of the other image manipulation tools do but it does what it does pretty well and maybe that functionality will follow in time.
