cfpdf - action - thumbnail

Description

cfpdf action thumbnail doesn't create thumbnails. Tested cfdocument and cfpdf "addWatermark" and they function properly. Tested code on cfml server and it functions correctly.

My code:

<cfpdf action="thumbnail" source="test.pdf" pages="1" imagePrefix="Cover" format="png" scale="50" resolution="low">

Environment

Windows, Lucee 5

There is another incompatibility with ACF. If the imagePrefix is not defined, lucee saves the images with the full file name with extension from source pdf i.e test.pdf_page_1.jpg But it is in ACF saves the images files without extension of source pdf i.e test_page_1.jpg
So In lucee: test.pdf_page_1.jpg
In ACF: test_page_1.jpg

I added a fix and testcase to this incompatibility in the above PR.

The action extractText also missing to close the PDFReader.
I've added a fix to close the PDFReader after the actions are finished.

Thanks for testing --I’ll get you a repro case, but regardless we can tell just from looking at the code that the PDFREader is not being closed which needs to happen, so the fix shuold be very obvious regardless slightly smiling face Also, the OS/filesystem in use may affect how the files are locked. I was running the code from a CommandBox Task Runner on Windows

thanks for pointing out the bug in this implementation.

unluckily I can't reproduce the source file locking issue with the cfpdf thumbnail in my local. After done action=thumbnail, I can able to rename/delete/move the source file via file explorer or cffile. Also, the testcase deletes the source file after the tests ran.

Could you please share the test code and which scanerio the file locks occurred? slightly smiling face
