great finding in print preview
Posted: Wed Sep 25, 2013 12:14 AM

Meanwhile I was testing some changes in Class TMetaFile (tmetafil.prg) I found that if I comment out this section of code, the print preview is incredibly much better!

I do appreciate your tests and comments, thanks!

Code (fw): Select all Collapse

METHOD Paint() CLASS TMetaFile

   local nVStep, nHStep

   if ::hMeta == 0
      if File( ::cCaption )
         ::hMeta = GetEnhMetaFile( ::cCaption )
      elseif ! Empty( ::cCaption )
         Alert( "Could not find the Metafile," + CRLF + "please check your TEMP environment variable" )
      endif
   endif

   if ::hMeta != 0

        ::Shadow()

        SetMapMode( ::hDC, MM_ANISOTROPIC )

        /*
        SetWindowExt( ::hDC, 100, 100 )
        if ::nVRatio == nil
           ::SetCoors()
        endif   
        SetViewportExt( ::hDC, 100 * ::nXZoom, 100 * ( ::nYZoom / 2 ) * ::nVRatio * ::nWidth() / ::nHeight() )
        nHStep = ( ::nWidth() * ( ::nXZoom - 1 ) ) / 9.8 
        nVStep = ( ( ::nWidth() * ::nXZoom * ::nVRatio ) - ::nHeight() ) / 10.3
        SetViewOrg( ::hDC, -::nXorig * nHStep, -::nYorig * nVStep )
        */
              
        PlayEnhMetaFile( ::hDC, ::hMeta, ::hWnd, .f. )

   endif

return nil

Antonio,

I tried your suggestion by commenting out the section you suggested.
Unfortunately, I can't see any difference.

What difference should we notice?

Thanks.

Michel,

Do your previews look like the Acrobat PDF previews ? We have to do more tests to find on what printer object instructions that makes a real difference. Here the improvement is outstanding, I will post some screenshots.

Could you please post a screenshot to see how it looks there for you ? thanks

Antonio,

Here is a screenshot without your change in the preview :

Here is a screenshot WITH your change in the preview :

I'm very sorry, but I can't see any difference.

Your opinion?

Michel,
for me it seems as you use bold in the first report.
The 2nd is much clearer.
Best regards,
Otto

Michel,

I don't know yet what printer actions may affect my proposed change, but here in some specific tests, there is a big difference. I will try to post some screenshots asap.

I am doing more tests and I will report here my findings, thanks
