How I can to resize a Image with software?

Not mouse!
Image->Resize(150%);

Inserting an image resized to 100x100, as an editing (undoable) operation:

Code: Select all

rve.TopLevelEditor.BeginUndoGroup(rvutInsert);
rve.TopLevelEditor.SetUndoGroupMode(True);
if rve.InsertPicture(...) then
begin
  rve.SetCurrentItemExtraIntProperty(rvepImageHeight, 100, True);
  rve.SetCurrentItemExtraIntProperty(rvepImageWidth, 100, True);
end;
rve.TopLevelEditor.SetUndoGroupMode(False);

Resizing the image at the caret position, as an editing (undoable) operation:

Code: Select all

if rve.TopLevelEditor.GetCurrentItem is TRVGraphicItemInfo then
begin
  rve.TopLevelEditor.BeginUndoGroup(rvutModifyItem);
  rve.TopLevelEditor.SetUndoGroupMode(True);
  rve.SetCurrentItemExtraIntProperty(rvepImageHeight, 100, True);
  rve.SetCurrentItemExtraIntProperty(rvepImageWidth, 100, True);
  rve.TopLevelEditor.SetUndoGroupMode(False);
end;

Adding an image to the end of document, when generating it (not undoable)

Code: Select all

rv.Clear;
<add something before the image>
rv.AddPictureEx(...);
rv.SetItemExtraIntProperty(rv.ItemCount - 1, rvepImageHeight, 100);
rv.SetItemExtraIntProperty(rv.ItemCount - 1, rvepImageWidth, 100);
<add something after the image>
rv.Format;
