Really sweet image cropper, modifiable via user drag and click input
Further instructions to get this to work as follows->
1. The cfImageCropper zip doesn’t contain all the files you need.
2. The docs refer to the optional scriptSrc attribute which points to the required javaScript docs you need; those files are in the lib folder of David Spurs’ jsCropperUI-1.2.0.zip.
3. The test.cfm demo file holds the key to the last missing piece: cropper.css. Todd’s test page points to the lib/ folder for it and David has it in the main directory. Certainly it can go anywhere but I dropped in the lib folder for the test and all was right in the world of cropping castles.
So to sum up; Your lib file should contain these 7 files:
builder.js,
cropper.js,
dragdrop.js,
effects.js,
prototype.js,
scriptaculous.js
cropper.css.
