print picture of signature

rbuser

Hallo,

we want to print a scanned signature on our reports,
but it seems to be quite grainy.
has this something to do with the dpi of the graphic-file ?
(it is a quite high-quality jpeg, which looks ok on screen)

Any ideas how to ensure that it looks good in print ?

thanks,
Nenad

Hi Nenad,

One thing you can try is to set the DirectDraw property to True. Also
stretching or shrinking the image may affect the quality, you may want to
use an imaging product to resize the image before adding it to the report.

Hi,

i have set DirectDraw to true,
Autosize to true
and changed the picture to .bmp.
Still it looks bad on the printout.

As a test i have overwriten part of the image (in an image-editor) with some normal text (in Arial)
this text looks also like it is processed in some way before printout
(grainy, antialiased)

Is there a way to print the picture as it is ,
without the RB (or the printer-driver ?) changing it ?

thanks,
Nenad

Nenad,

Which version of ReportBuilder and Delphi are you using? What type of
printer are you printing to? Do you get this behavior on all printers and
with all bitmaps? In all of our tests, image displayed and printed with
ReportBuilder are of the same quality as any other application.

ReportBuilder essentially draws an image directly to a canvas via Windows
API commands. If you intend to print this picture, the use of the printer
driver is necessary. Be sure your printer is capable if printing a high
quality picture and that your printer driver is up to date.
