Size adjustment is available for standard implementation of metafiles, bmp

and jpeg.

It is not available for icons.

There are several different gif implementations, you can test them yourself.

This code scales the current image (in the position of caret) to 100 x 100:

// minimal code:

if rve.CurItemStyle in [rvsPicture, rvsHotPicture] then

begin

  RichViewEdit1.SetCurrentItemExtraIntProperty(rvepImageHeight, 100, False);

  RichViewEdit1.SetCurrentItemExtraIntProperty(rvepImageWidth, 100, True);

end;

  OR

// if you want these operations to be undone as one operation:

if rve.CurItemStyle in [rvsPicture, rvsHotPicture] then

begin

  MyRichViewEdit.BeginUndoGroup(rvutModifyItem);

  MyRichViewEdit.SetUndoGroupMode(True);

  RichViewEdit1.SetCurrentItemExtraIntProperty(rvepImageHeight, 100, False);

  RichViewEdit1.SetCurrentItemExtraIntProperty(rvepImageWidth, 100, True);

  MyRichViewEdit.SetUndoGroupMode(False);

end;

PS: for other readers: this code requires a last version which is currently

available only for registered users.
