black images

rbuser

Hi

I am using Delphi 6 with ReportBuilder 9.03

Sometimes it happens with reports that the images on a report a completely
black.
Sometimes it goes ok, and a few minutes later it goes wrong and the image
turns black.

We have this problem with several customers with several users on various
computers.

Any idea?

Hi Andre,

This is not a known issue for RB 9.x. We had problems with black images
with earlier versions of ReportBuilder (pre 7.04) however they were fixed
with some enhancements to our image processing logic. Are you only seeing
black images when printing reports? Be sure your users are using the latest
printer drivers. Also, try having them turn the Transparent property off
for any images and see if that helps (some printers cannot handle
transparent images well).

Hi Nico,

Thanks.
It happens when previewing, printing and when creating a PDF file. The
bigest problems we have is with PDF files.
Our software generates a lot of documents to PDF and sometimes (with
different customers and computers) the images are black.

The transparant option was already turned off. I put DirectTrue to true now.
Mayby that helps.

Also be sure you have checked your application for memory leaks.

Hi Nico,

Thanks,
Setting the DirectTrue property to True did not help.
Memory leaks are difficult to find. I am not sure when it happens. At the
begin of the day or at the end. I can imagine it has something to do with
this. If you running out of memory, that then ReportBuilder has no resource
to load the image.
On my computer is never happens. But I have 2GB and I run the program for a
short period of time to test the software. I never work with it like my
customers do.

Any suggestions to find memory leaks?

Hi Andre,

Try taking a look a the memory manager such as FastMM. This is a free
memory manager and works well with Delphi.

Thank Nico,
I going to have a look at this.
I just adjusted our software in a way that it check if the image is black.
If so it will automatically retries 10 times to build up the document. If
the image is still black the user gets a message. In this message I will
mention also the amount of free memory.
Hopefully this helps to solve this quickly for now.
