tppImage Picture.Data not saved in template

rbuser

Hello All

D5, RB 6.03

We have a report explorer ( incl designer ) in our main app which correctly
saves image data to the .rtm file as Picture.Data ( ftAscii ). This is an
Image ( not a DBImage )

We also have a report 'dump' utility which simply extracts all the templates
from a database and saves them as .rtm files for distribution purposes. This
utility just uses a report component. If the database template contains an
image, it does not appear to be saving the Picture.Data to the template
file, why is this ?

I have noticed that the image data is only missing if the image is in the
detail band and is saved correctly when the image is in a header or footer
band.

There is nothing in RB to prevent the image data from being saved. This is
most likely a database issue.

If you are using the BDE, try increasing the MaxBlobSize setting. Image data
will increase the size of the report. You can save the report to an .rtm
file and use Windows Explorer to check the size of the .rtm file. That will
give you an idea of how big the template is.

Thanks Nard

Perhaps I didn't explain clearly but the image data is fine within the DB
templates, it's only when it's saved to the .rtm file. Saving to file via
the explorer is fine but the when the dump utility does a
Template.SaveToFile, there isn't always a Picture.Data section for the
image. i.e. examination of the .rtm via notepad or re-loading the template
into the report explorer shows an 'empty' image.

Try creating a very simple, minimal example that demonstrates this behavior.
Use only standard Delphi components, ReportBuilder, and perhaps paradox
tables. E-mail in zip format to support@digital-metaphors.com and we can run
here in the Delphi debugger.

Hi Nard

I discovered that the images were saved OK if they were in .bmp format but
not in .jpeg.
Adding jpeg to the uses clause solved the problem. It would have been useful
to get a warning/exception about this somewhere rather than simply to drop
the picture data.
