Group codes Description

100

Subclass marker (AcDbRasterImage)

90

Class version

10

Insertion point (in OCS)
DXF: X value; APP: 3D point

20, 30

DXF: Y and Z values of insertion point (in OCS)

11

U-vector of a single pixel (points along the visual bottom of the image, starting at the insertion point) (in OCS)
DXF: X value; APP: 3D point

21, 31

DXF: Y and Z values U-vector (in OCS)

12

V-vector of a single pixel (points along the visual left side of the image, starting at the insertion point) (in OCS)
DXF: X value; APP: 3D point

22, 32

DXF: Y and Z values of V-vector (in OCS)

13

Image size in pixels
DXF: U value; APP: 2D point (U and V values)

23

DXF: V value of image size in pixels

340

Hard reference to imagedef object

70

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

280

Clipping state: 0 = Off, 1 = On

281

Brightness value (0 - 100; default = 50)

282

Contrast value (0 - 100; default = 50)

283

Fade value (0 - 100; default = 0)

360

Hard reference to imagedef_reactor object

71

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.

24

DXF: Y value of clip boundary vertex (in OCS) (multiple entries)
