Linking to Jpeg Image stored in Database

rbuser

I have a report which links to an image field in a TDataSet. When this
is a bitmap then all is well, but it won't even open the report if it
is a JPEG.

What's the best way to handle this?

Thanks

For RB 12, set DBImage.GraphicType to AutoDetect and it will automatically
determine the graphic type by analyzing the stream header.

For prior versions, set DBImage.GraphicType to JPEG and include ppJPEG in
the uses clause of the project.

Thanks. I am using 11. Is there a way to default this when an DBImage
is created. At the moment it throws an exception when an image field is
dragged onto the designer and then when you do any actions until the
type is set to JPEG.

I have tried setting the GraphicType to JPEG in the
Designer.OnComponentCreate which is half way there but it still throws
an exception before this event is called.

I recommend updating to RB 12. The DBImage.GraphicType defaults to
AutoDetect. Download a trial version and give it a try.

Using the OnComponentCreate would have been my other recommendation.

Well, yes that would be an option but as this is a sytem that I'm doing
for my daughter's Ph.D that is the expensive option as I won't get to
charge it on to a client :-)
