Can you please let me know how to select image coordinates of the pdf files? or draw the box above the images?

I can able to find an only the images found or not.Using the below codes.

'Check Image Found or not

FileName = "c:\pdf\VBJavaScript.pdf"
h = QP.DAOpenFile(FileName, "")
p = QP.DAFindPage(h, 1)
Call QP.FindImages
imlist = QP.DAGetPageImageList(h, p)
imcnt = QP.DAGetImageListCount(h, imlist)
If imcnt = 0 Then
MsgBox "No Images"
Else
MsgBox "Image Found"

Hi!

Again... QP isn't great help in doing the described things.
Additional "FindImages" is buggy with memory-errors on bigger files.

What you can do with QP is to unencrypt the file and save it again unprotected. Then you can load the content into a stream and analyze it. You'll find there all objects with coordinates and much more. To access content QP offers few functions...

Best regards,
