Terabyte Image Cropper

Note: This project is no-longer under active development. Consider using the now built in cropper.

A simple Image cropper with flexible validation.

Features

• Upload your JPG, if it's too big jCrop will appear so you can crop your image
• Flexible Validation for dimesion, filesize, filename
• Shrinks the raw image to fit your browser to make cropping very large images easy.
• The uploaded image is cropped asynchronously in the edit page.
• The uploaded 'raw' file is overwritten with the cropped file when you click 'crop'.

Usage
Regex validation is performed against a string of this format:
IsValidSize:true|Width:200|Height:100|Length:400|Extension:.jpg|Name:blah.jpg
Therefore to validate the image is the correct size, use this regex:
.*IsValidSize\:true.*

Configuration (optional Web.Config entry)
<add key="ImageCropperIgnoreMissingFiles" value="false"/>

Known Issues & Limitations

• Does not work with "Media"
• Only works with .jpg files.
• cropper fails to initialise if not on the 'loaded tab' see forum post[1] for details:
• Only works with files in jpg format see forum post[1] for details
• Has issues with some characters in the filenames, see forum post[2] for discussion.

Roadmap (wish list)
I'd like to add the option to fix one dimension of the crop and allow th user to select the other, eg: fixed width variable height.
