Image display properties:
1 = Show image
2 = Show image when not aligned with screen
4 = Use clipping boundary
8 = Transparency is on

Clipping state: 0 = Off, 1 = On

281

Brightness value (0 - 100; default = 50)

282

Contrast value (0 - 100; default = 50)

283

Clipping boundary type. 1 = Rectangular, 2 = Polygonal

91

Number of clip boundary vertices that follow

14

Clip boundary vertex (in OCS)
DXF: X value; APP: 2D point (multiple entries)
Notes:
1) For rectangular clip boundary type, two opposite corners must be specified. Default is (-0.5,-0.5), (size.x-0.5, size.y-0.5).
2) For polygonal clip boundary type, three or more vertices must be specified. Polygonal vertices must be listed sequentially.
