Hello,

This is impossible to implement directly. But you can get the sizes of CAD images. For TsgDXFImage, TsgDWGImage, TsgSVGImage and TsgCGMImage:

Code: Select all

var
  vRect: TFRect;
...
begin
...
  vRect := TsgDXFImage(sgPaintBox.Picture.Graphic).Extents;
  ImageWidth := vRect.Right - vRect.Left;
  ImageHeight := vRect.Top - vRect.Bottom;
...
end;

<b>Note</b>:
the returned values are in inches if:

Code: Select all

TsgDXFImage(sgPaintBox.Picture.Graphic).CurrentLayout.PlotSettings.PlotPaperUnits = 0 

else in millimetres.

For TsgHPGLImage:

Code: Select all

     ImageWidth := TsgHPGLImage(sgPaintBox.Picture.Graphic).MMWidth / 100;
     ImageHeight := TsgHPGLImage(sgPaintBox.Picture.Graphic).MMHeight / 100;

<b>Note</b>:
the returned values are the 100-th shares of millimeter

Hello,

They can get sizes of the drawing only when it has been loaded. Knowing sizes of the drawing and sizes of sheets they can select acceptable format of the sheet for printing.

Could you please explain in detail what tasks are standing before you for we'd find the easiest way to solve them.
