cannot create jpeg from pdf

Hi

This now works. Sorry but I may have been using the wrong version of the dll file before which may have explained why is wasn't working.

I also had to fix a fault in the WPViewPDF1 unit. For TWPPDFViewOption it had values of wpPageSelection and wpPageMultiSelection but the code referred to wpShowPageSelection and wpShowPageMultiSelection.

Regards

Stephen

Hi,

I made a test right now - it works. Please try the latest setup (V1.46.5) suince it includes a change inn the make JPEG procedure. Maybe it was a problem there. If this does not help please send me PDF.

Sorry, I should have been clearer. I am already doing this, e.g.

WPVIEWPDF1.LoadFromFile('C:\TEMP\wPDFMan.PDF');
ret := WPVIEWPDF1.CommandStr(COMPDF_MakeJPEG, '1=C:\TEMP\wPDFMan.jpg');

ret is -1 and no file is created

when I do

ret := WPVIEWPDF1.CommandStr(COMPDF_MakeEMF, '1=C:\TEMP\wPDFMan.emf');

ret returns 1 and the file is created

Hi,

you need to specify the page number:

"1=c:\pageone.jpg"

in the file name parameter.

I am using WPViewPDF 1.46 and trying to create a jpeg file using the CommandStr(COMPDF_MakeJPEG, filename) method and I always get a -1 result. Using COMPDF_MakeEMF works fine.
