print job size using screen resolution

rbuser

Why does that size of a print job dramatically increase when the user
changes his/her screen resolution?

Eg The size of my print job (includes images) is much smaller <1 mb when I
am running 16bit colour Display Properties on my computer but is increased
to 20mb when I change to High colour!...

Can I control this file size from within Reportbuilder?

PS The quality of the printout is the same in both examples.

Hi James,

We have never seen (or noticed) this behavior before. Which version of
ReportBuilder / Delphi are you using. Which model printer are you using?
We are constantly trying to improve our image rendering code so once I get
the information on your printer, I'll try installing the driver and see if I
can track down the problem.

The problem appears to be with the Colour component in Delphi and is the
same for all of the standard report writer programs. (and all versions
Delphi regardless of the output device )

Colour selects the 'colour depth' from the users current Windows setting,
and this is dramatically increasing the print job size but does not effect
the output quality.

So I want to be able to set the colour depth programmatically when producing
the report...any ideas?

Hi James,

I'm a little unclear about what you mean by the Delphi Color component. Is
this a property somewhere that is sets the color depth? I believe Delphi is
forced to change all your images to the current windows color depth setting
before showing them to the screen. This is the way bitmaps are rendered to
the printer as well. Therefore you may need to change your windows color
depth to get a smaller print job.
