Hi,

I am using the following code to open RTF file from a memory stream:

      RichViewedit1.Clear;
      RichViewedit1.LoadRTFFromStream(MyStream);
      RichViewEdit1.Format;

The RTF files that I am opening contain pictures. I have noticed that by default the pictures are not scaled to 100% (original size).

Is there an option to automatically scale all pictures in an RTF file to 100% prior to being displayed to the user?

Thanks for your time

Do you want to ignore picture scaling specified in RTF and display all pictures in their original size?

Use the following procedure:

Code: Select all

procedure ResetPicSize(RVData: TCustomRVData);
var i,r,c: Integer;
    Table: TRVTableItemInfo;
begin
  for i := 0 to RVData.ItemCount-1 do
    case RVData.GetItemStyle(i) of
      rvsTable:
        begin
          Table := TRVTableItemInfo(RVData.GetItem(i));
            for r := 0 to Table.RowCount-1 do
              for c := 0 to Table.ColCount-1 do
                if Table.Cells[r,c]<>nil then
                  ResetPicSize(Table.Cells[r,c].GetRVData);
        end;
      rvsPicture, rvsHotPicture:
        begin
          RVData.SetItemExtraIntProperty(i, rvepImageWidth, 0);
          RVData.SetItemExtraIntProperty(i, rvepImageHeight, 0);
        end;
    end;
end;

Call:

Code: Select all

      RichViewedit1.Clear; 
      RichViewedit1.LoadRTFFromStream(MyStream); 
      ResetPicSize(RichViewEdit1.RVData);
      RichViewEdit1.Format;
