Need help using ImageCrop()

  • November 10, 2015

I have passed an image and crop values to my form action page. I want to crop the image and then save it to disk. the imagecrop() function s returning an error: The result of the method ImageCrop cannot be assigned because it does not return a value.


Here's what I've tried:

<cfset myImage = ImageReadBase64("#form.xBase64PhotoString#")>

<cfset myImage=ImageCrop(myImage,Val(form.x),Val(form.y),Val(form.w),Val(form.h))>

<cfimage source="#myImage#" destination="c:/workgroups/webdata/badgecards/#BadgPhotoName#" action="write" overwrite="Yes">

The imagecrop is a new process for this existing template. The bse64 and cfimage/destination lines work fine.

Thanks in advance.

Lyndon

    The error message tells you what the problem is. The ImageCrop function does not return a value. Don't try to assign a non-result to a variable. In other words, remove "myImage=" from the problem line.

      Perfect!

      That was in the examples; I couldn't see the forest for the trees I guess.

      Thank you
