Overview

Let the server resize, crop, and process your images without sacrificing speed or scalability. Use HTML, ASP.NET, ASP, PHP, Flex, or Flash ... Just add the desired behavior to the URL with "?width=100" or "?format=jpg". Supports scaling, cropping, rotating, flipping, stretching, padding, borders, transparency, jpeg, png, gif, bmp, tiff, and psd formats. Used by dozens of commercial CMS systems and hundreds of web sites, this module has an unparalleled satisfaction rate and incredibly quick support. And on top of everything else, it's free.

Features

Command Reference

  • width, height - force the width and/or height to certain dimensions. Whitespace will be added if the aspect ratio is different.
  • maxwidth, maxheight - fit the image within the specified bounds. (Most often used)
  • crop=auto - Crop the image the the size specified by width and height. Centers and minimally crops to preserve aspect ratio.
  • crop=(x1,y1,x2,y2) - Crop the image to the specified rectangle on the source image. You can use negative coordinates to specifiy bottom-right relative locations.
  • rotate=degress - Rotate the image.
  • bgcolor=color name| hex code (6-char). Sets the background/whitespace color.
  • stretch=fill - Stretches the image to width and height if both are specified. This is the only way to lose aspect ratio.
  • scale=both|upscaleonly|downscaleonly - By default, images are never upscaled. Use &scale=both to grow an image.
  • flip=h|v|both - Flips the image after resizing.
  • sourceFlip=h|v|both - Flips the source image before resizing/rotation.
  • paddingWidth=px & paddingColor=color|hex. paddingColor defaults to bgcolor, which defaults to white.
  • borderWidth=px, borderColor=color|hex.
  • format=jpg|png|gif
  • colors=2-255 - Control the palette size of PNG and GIF images. If omitted, PNGs will be 24-bit.
