Tif Images - GraphicEx Example

rbuser

Nico, it will be very hard to break out what we are doing in our program.

Can you send to me the example that you are testing with for the GraphicEx
for tif images?

That would give us an actual example to examine.

Thank you.

Hi Bill,

Are you able to see the TIF file using the demo browser that comes with the
GraphicEx package?

What is the AV you are receiving? The second time I installed GraphicEx on
my computer, I was able to get an AV claiming "The compression scheme is not
supported for TIF/TIFF files". Is this the AV you are getting? If not, it
is probaby because I am not using a proper Tiff file (I'm converting a JPEG
with PaintShop Pro). I receive this AV when using ReportBuilder and the
GraphicEx demo browser as well so it is not RB specific. Would it be
possible for you to send me a copy of the TIF image that you are trying to
load into the report? Then I could have a closer look at what exactly needs
to happen. Thanks.

I am not getting a compression scheme error. I am getting an "Invalid
image. Cannot generate report." error. But the error is pointing back to
GraphicEx.

Further, investigating the GraphicEx.pas file reveals that most tif
compression schemes are not supported including the one I need which is
Group 4. This was confirmed by trying to use the GraphicEx browser on the
tif directory. Uncompress tif files showed up fine.

So the next question is "What are people using to print tif files with Group
4 compression?" which is used quite extensively. I will post as a new
question to the newsgroup to catch a possible answer.

What does DM suggest?

I am now looking at the ImageLib components that we already own and see if
that is a possibility. I will reveal my results when completed. And tell
Tom and Nard hello. Are they both in Colorado where it is cool in the
summer. This Texas heat is a killer now.
Thank you looking.

Hi Bill,

ReportBuilder supports image libraries that descend from TImage such as
GraphicEx. After searching the Internet, I was unable to find anything for
Group 4 compression of Tiff files that descends from TImage. You might try
posting a question on the Borland groups asking for a product that could
help.
