Export to metafile not producing correct output for BDS2006

rbuser

Hello,
I'm looking at exporting reports to EMF. When I run your sample app
from the following url I get correct output using delphi XE but the
output is 'squashed' when using BDS2006. Is there some way to get the
correct output with delphi 2006 or is this a bug?

Hi Will,

Which version of Reportbuilder are you using? In my testing with Delphi
2006 and RB 14.05, the exported EMF file is scaled correctly when
running the example in the RBWiki article.

Nico,
I'm using 14.05. On further investigation it seems this has nothing
to do with delphi edition but something to do with the pc it's running
on. I have delphi XE installed on windows 7, this works fine. I also
have bds 2006 on an XP virtual machine hosted in virtualbox on the
windows 7 pc. The XP VM produces squashed output using the binary from
either delphi edition. Windows 7 produces the correct output from
either delphi edition.

Regards,
Will.

Hi Will,

We have not heard of this issue with exporting metafiles with Windows
XP. How are you viewing the metafiles? Are you able to try on a
separate XP machine rather than a virtual machine?

Can you send a simple project in .zip and the good and bad image results
for m??

Hi Will,

This is interesting. So the image is only incorrect when created on the
virtual machine.

ReportBuilder leverages Delphi's TMetafile object to create the metafile
images of the pages and the size of the image is calculated inside the
TppMetafileDevice.InitializeImage routine (ppImageDevice.pas).

Perhaps you could trace into this routine on your Win 7 machine and your
virtual XP machine and see if there is a difference in Width and Height
values.

Do you by chance have a default printer installed on your virtual
machine? If so, what is the print resolution of the driver set to?
