With Ctrl+V, images can be pasted:

1) if the Clipboard contains RichView Format

2) if the Clipboard contains RTF

3) if the Clipboard contains bitmap.

You can easily modify images in cases (2) and (3).

For (2), it can be done with RV_AfterImportGraphic (I was wrong in my

previous reply, this variable is defined in RVFuncs unit).

For (3), it can be done in OnPaste event (paste image from the Clipboard

itself, modify it and insert in the RichViewEdit).

I created a demo:

http://www.trichview.com/support/files/pastewatermark.zip

It draws "pasted" in the top left corner of all pasted bitmaps.

As for (1), the only way to modify images is pasting data to the hidden

editor, modify all images in it, then insert in the main editor. But I do

not think it's necessary, because this format is copied to the Clipboard

only by TRichView.
