How to assign a bitmap image to TppImage component at run time?

rbuser

Hi,

I have a TppImage in the report, I try to call
Image1.Picture.BitMap.LoadFromStream(...), but it can't be compiled.

What am I wrong?

Thanks

Hi William,

Where are you getting the initial image from? Is it on a database or in a
memory stream of some sort? If the image is in file, try using the
LoadFromFile method. If the image already exists on a form perhaps, try
using the TppImage.Picture.Assign method to assign the TppImage to the
original.

Hi, Nico

I have a signature bitmap save in the windows registry, and defined a
report function (registered through raRegisterFunction) to get the bitmap
image from registry and save it into a Variant variable, but next step is
how to assign this variable into the TppImage?

Thanks

William

Hi William,

The LoadFromStream function is not natively included in RAP. You will need
to create a pass-thru function to handle this case. For information on
creating RAP pass-thru functions, please see the ReportBuilder Developer's
guide.
