Hi All,
I'm using this tag to grab an image file uploaded by an end user through
a "file" form field.
I want to convert it to jpg and resize it if necessary (borrowing from a
CFDJ article.
Three issues:
1) I keep seeing in the HOF list archives that developers are using an
ACTION="iml", though I can't find documentation for that attribute
anywhere in the CFX_Image docs (v1.6.6.9). What does this Attribute do?
2) If I need to do a two-step process, for example, resizing the image
AND converting the file to another format, should I first resize, then
park the output in a temp directory, then in the second step, grab the
image from the temp directory then output to the final directory?
3) After the conversion/resizing process, I want to grab the full file
path, then write this info to a database. How do I get the final image
name and CFSET as a variable, so I can do a db insert.
I've attached my code below (note that I'm Cfincluding this, so that db
inserts won't be listed here):
Thanks,
Mark
