Hi,
Does anyone know what is the difference on how ImageEn save its content to the database vs. ImageLib?
I am having problem with image saved by ImageEn (BMP works fine but other like JPEG, GIF, PNG, etc) does not work when Reportbuilder by Digital-Metaphors try to render it on the report (return with invalid image error code 53).
Any suggestion is greatly appreciated.
I am using these components in Delphi 7 and Delphi XE8. The reason for the switch is because ImageLib is no longer in business.
Thanks,
Vinh,

Hi

I'm not sure why ReportBuilder should be so picky about a standard such as JPEG, but I would try changing the JPEG parameters such as:

http://www.imageen.com/help/TIOParams.JPEG_OptimalHuffman.html
http://www.imageen.com/help/TIOParams.JPEG_Progressive.html
http://www.imageen.com/help/TIOParams.JPEG_ColorSpace.html
http://www.imageen.com/help/TIOParams.JPEG_DCTMethod.html

e.g.

ImageEnView1.IO.IOParams.JPEG_OptimalHuffman := True;
ImageEnView1.IO.Save...

ImageEnView1.IO.IOParams.JPEG_DCTMethod := ioJPEG_IFAST;
ImageEnView1.IO.Save...

Hi,
My apology for our dump mistake in code. The short story is we have a line of code at runtime to tell ReportBuilder the image type to load and for whatever the reason the image extension save by ImageEn is different than what ReportBuilder is expected in the GraphicType property so it failed to load.
To solve this problem, we set the GraphicType property in ReportBuilder to "AutoDetect" and program is working as intended.
Thank you,
Vinh,
