RBuilder 12 + Delphi 7 + PNG support

rbuser

Hi!

I have read about new DBImage autodetect feature. It's great!!

But... does it support PNG format?

The single 'Image' component (not DBImage) supports PNG files, but DBImage
just let me choose from AutoDetect, Bitmap, JPG, Gif, Icon and Metafile.

Thanks!

Delphi 2009 VCL and later included built-in PNG support. ReportBuilder for
Delphi 2009 and later display a DBImage GraphicType for PNG.

For Delphi 7 you must be using an add-on component for PNG support. The
ReportBuilder help topic for DBImage.GraphicType says

"Any TGraphicClass descendant can be registered and used with the DBImage
component. For an example of registering a TGraphicClass with ReportBuilder,
see the ppJPEG or ppGIF unit."

So if you need to create myPNG.pas unit and register that with
ReportBuilder. Run-time registration is achieved by simply referencing the
unit in the 'uses' clause of your project. Delphi design-time registration
is achieved by installing a package.

Going forward, hope you will be upgrading your Delphi 7...
