Adding a picture with specific size (like HTML)

Post by EugenioAndres » Mon Sep 12, 2005 3:46 am

Hi,

Is there a way to insert a picture into a TRichView giving it a specific size, independently of the pixels in the image file itself? - like in HTML, when a width and heigth are specified.

Thanks in advance.

Sounds like you should do the resizing prior inserting the image though you may want to check out the various attributes associated with pictures in TRichView/Edit.

Document generation:

Code: Select all

rv.Clear;
..
rv.AddPictureEx(...);
rv.SetItemExtraIntProperty(rv.ItemCount-1, rvepImageHeight, 100);
rv.SetItemExtraIntProperty(rv.ItemCount-1, rvepImageWidth, 100);
...
rv.Format;
Inserting picture:

Code: Select all

if rve.InsertPicture(...) then begin
  rve.SetCurrentItemExtraIntProperty(rvepImageHeight, 100, True);
  rve.SetCurrentItemExtraIntProperty(rvepImageWidth, 100, True);
end;
This example is simple, but not very good, because user can update all these 3 operations (inserting, changing height, changing width) in 3 steps, calling Undo 3 times.
The code below solves this problem:

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);
