include an image in a TppRichText?

rbuser

Is it possible to place an image inside of an TppRichText at runtime?

I'm copying some rtf which includes an image into a ppRichText via the
LoadFromRTFStream method. But the image doesn't appear.

Is there a workaround for this?

Thanks,

Jason

Article: ReportBuilder's RichText architecture
----------------------------------------------

The RichText in ReportBuilder is a wrapper around Delphi's TRichEdit which
in turn relies on Windows.To use some of the more advanced features of
Windows RichEdit, see the topic on InfoPower RichEdit Support below.

In general Windows RichEdit supports the type of formatting that you can do
using WordPad.



InfoPower RichEdit Support
---------------------------
InfoPower from Woll2Woll Software is a popular database add-on product for
Delphi. InfoPower's TwwRichEdit components support the Windows RichEdit2
format. This format allows the rich text data to contain embedded bitmaps
and OLE objects. For more information please see http:\\www.Woll2Woll.com.

ReportBuilder includes a component that enables the TppRichText and
TppDBRichText controls in ReportBuilder to use the formatting capabilities
of InfoPower's TwwRichEdit when rendering RTF data. The ppWWRichEd.pas unit
located in the ..\RBuilder\InfoPower directory defines a TwwDBRichEdit
descendant and then registers the class with ReportBuilder. This enables the
TppRichText and TppDBRichText controls in ReportBuilder to use the
formatting capabilities of TwwDBRichEidt when rendering data.


WPTools Support
----------------
WPTools is a collection of components used to edit and print formatted text.
With its own RTF engine, WPTools offers numerous features not supported by
the standard Windows RichEd20.dll. This control lets you use tables,
paragraph frames, headers and footers etc. Using the optional ReportBuilder
support units for WPTools 2.x, you can print the enhanced WPTools features
(justified text, tables, graphics...) within your ReportBuilder reports. For
more information please see http:\\www.wptools.de.

TRichView
----------
TRichView is a suite of native Delphi components for displaying, editing,
and printing hypertext documents. Documents can contain tables, pictures,
and images. TRichView is available from www.trichview.com. There is a
wrapper for available for using TRichView inside ReportBuilder, see
http://www.digital-metaphors.com/Subpages/Downloads/CompanionRCL.html or
http://www.trichview.com/resources/

Nard,

I happen to have the InfoPower suite installed, so that's what I installed.

However, even after installing the resulting packing into Delphi, it
still doesn't copy over images with the RTF. I did notice that this
package doesn't actually have any components in it.

Do I have to do something in particular to make the TppRichText use the
TwwDBRichText properties?

Thanks,

jason

Nard,

I did get the InfoPower wrapper installed. I can insert images in the
RTF box at design time.

But I can't seem to put images in at runtime. I've tried the load from
LoadFromRTFStream method, but it still doesn't work. I'm copying RTF
from a TStringList, and if I do a TStringList.SaveToFile('test.rtf'),
the test.rtf file will have the rtf text and the image.

But if I try to copy the RTF from that same string list to a pprichtext,
it won't work. All the images are removed.

Any ideas?

Try separate tests using TppRichText.LoadFromFile, LoadFromRTFStream,
RichTextStrings and setting the TppRichText.RichText property (which is of
type string). Those all should work.

I tried all of those methods, they all seem to strip out the image.

Are you including ppWWRichEd in the 'uses' clause of your app?

I just added it, but no difference. The image is still stripped out.

Nard,

My mistake. I didn't have the ppWWRichEd in the Uses clause.

I added it and it worked great with the image!

Thanks so much for your help on this.

Jason
