Introduction

TDwgPreview is a Delphi 2 component (also available as D3, D4, D5 and D6 component) that displays an AutoCAD drawing's preview. This is possible for AutoCAD R13, R14, R2000/2002 and R2004 drawings only.

AutoCAD 13 supports previews in BMP and WMF format. So does TDwgPreview.

AutoCAD 14 always saves previews in BMP format.

AutoCAD 2000/2002/2004 always saves previews in BMP format.

Properties

As you can see, even at design time the TDwgPreview component accepts a Filename and displays a preview. The Revision property will be set accordingly.

If Inverse is True, the background is set to black, otherwise the background is white. Inverse and Stretch also work at design time.

The Result property will show whether the drawing file contains a preview in BMP format (rBmp), WMF format (rWmf), both formats (rBmpWmf), or none (rNone). If a drawing contains both a BMP and a WMF, you can set the Result property to your preference before setting Filename.

If Stretch is set to False, Height and Width reflect the size of the preview.

 

Events

There is not much to say here.
