Corel.PRG - EMF bug

Corel.PRG - EMF bug

Postby Davide » Wed Nov 19, 2008 4:00 pm

Hello all,

I noticed that ImportWMF() places the image in different positions if Preview is enabled or not. Looks like Preview adds an additional margin on top-left corner.

Please try the sample Corel.prg - The result is in the 2 PDF's below:
http://www.2shared.com/file/4310298/b8cea73f/preview.html
http://www.2shared.com/file/4310311/809ffa4/nopreview.html

As you can see the text is in the same coordinates, while Invoice.EMF is not.

How can we fix this bug ?

Thanks,
Davide

Corel.PRG - EMF bug - Solved (perhaps)

traced back the problem in Printer.prg method ImportWMF():
Code: Select all  Expand view
   if ! ::lMeta
      SetViewOrg( ::hDCOut, -::nXoffset, -::nYoffset )
   endif

By commenting those lines, the problem gets cured, but it seems to be intentional.

Why the offsets should be considered only if Preview is disabled ?
Antonio ?

Davide,

We implemented the Method ImportWMF() for a FWH user that needed it. Probably in his case it was required as he was satisfied with the results.

We can modify that code, no problem.

I just checked that it's so since at least FW24 (2003). Don't have older versions still installed to check.

I would suggest to comment those lines in the standard lib however because most often a client uses the preview to place the text inside a form (like Corel.prg). At the end of the job the result is different if preview is disabled.

Davide,

I assume that most FWH users use EMF files instead of WMF ones.
But I may be wrong.

Maybe you can just change the PRG there for your own use.

the problem affects both (effectively I experienced it with an EMF) as method ImportWMF() is used to import either WMF's or EMF's

P.S. I'm already using a custom Printer.prg. Just wanted to contribute a bug fix
