Printing ImageEn Images in End User Designer

rbuser

I am using D7.1 with BDE, RB 7.04, and ImageEn 2.1.5.

Has anyone tried printing non BMP images in ReportBuilder? It doesn't seem
to work.

Hi Issac,

Which type of images are you trying to print? ReportBuilder natively
supportes bmp, jpeg, and gif image formats and with the use of GraphicEx
Delphi addon, numerous other formats are available.

---------------------------------------------------------------------
Article: ReportBuilder Image Support
---------------------------------------------------------------------

ReportBuilder natively supports .bmp, .jpeg, .wmf, .ico image formats.

ReportBuilder has an open architecture that supports any TGraphic
descendant.

For example, ReportBuilder ships with a freeware component called GIFImage
that can be used with ReportBuilder to print .gif images. (see the main
report demo app for an example.)

There is another freeware component called GraphicEx that
supports several additional formats - including tiff, targa, and autodesk.

It can be downloaded from:

http://www.lischke-online.de/Graphics.php


ReportBuilder can easily support TGraphic descendants
with a simple register call.

Below is the code to our ppGIF.pas unit which
'uses' and registers the freeware GIFImage component.

ppUnRegisterGraphicClass(TGIFImage);

end.

Thanks for the info, but I can't seem to get jpegs to display. The Image
GraphicType only allows for BMP, Icon, and Metafile. Is there something that
I am missing?

Try adding ppJPEG to the uses clause.

Thanks. That worked great.

Is there a way to have the DBImage component autosize?

nardmoseley

The TppImage has an autosize feature, but the DBImage does not - perhaps
something we can add to a future release.

The TppImage resizes the bounds of the control to match the size of the
picture. Try adding some similar code to the Band.BeforePrint event:

uses
ppPrnable, ppCtrls;

if (myDBImage.Picture.Width > 0) and (myDBImage.Picture.Height > 0) then
myDBImage.spSetBounds(myDBImage.spLeft, myDBImage.spTop,
myDBImage.Picture.Width, myDBImage.Picture.Height);

Thanks. I would really like to see DBImage.Autosize available in a future
release.
