How to enhance image-quality => oPrinter:SayImage ?
Posted: Mon May 19, 2014 06:12 PM

Hello,

is it possible, to get a better image-quality using oPrinter:SayImage

I added a print-solution and noticed a bad image-quality.

The image on screen ( JPG 1500 x 2300 )

The image on print-preview
the size is calculated to fill a DIN A4
oPrinter:SayImage( 260, 150, oDrawImg, nImgWidth * 0.83, nImgHeight * 0.83 )

Since 1995 ( the first release of FW 1.9 )

i work with FW.

If you have any questions about special functions, maybe i can help.

Hi.
I have a JPG file, so I must use the sayimage method.
The strange thing is that if I print directly there is no problem.
That blurry effect appears only in the preview window.

I made just now a test. I've opened the file in the temp directory, where windows places
the EMF files. The file is correct, with no problem at all.
Maybe that effect is made by the EMF viewer in the preview window.

Please try using oPrn:PrintImage(...)

Code (fw): Select all Collapse

function PrnImage()

   local oPrn

   local nRow     := 500
   local nCol     := 500
   local nWidth   := 352 * 5
   local nHeight  := 450 * 5
   local lStretch := .t.

   PRINT oPrn PREVIEW
   PAGE
      oPrn:PrintImage( nRow, nCol, "c:\fwh\bitmaps\olga1.jpg", nWidth, nHeight, lStretch )
   ENDPAGE
   ENDPRINT

return nil
