 CONSTRUCTOR(
	fileName AS STRING,
	width AS LONG,
	horizontalResolution AS REAL8,
	height AS LONG,
	verticalResolution AS REAL8,
	units AS ImageResolutionUnits
)

Parameters

fileName

Type: SystemString
Image file name with full or relative path.

width

Type: SystemInt32
Image width in pixels.

horizontalResolution

Type: SystemDouble
Image horizontal resolution in pixels.

height

Type: SystemInt32
Image height in pixels.

verticalResolution

Type: SystemDouble
Image vertical resolution in pixels.

units

Type: DXFReaderNETImageResolutionUnits
Image resolution units.

The name of the file without extension will be used as the name of the image definition.

This is a generic constructor for all image formats supported by AutoCAD, note that not all AutoCAD versions support the same image formats.

Note (this is from the ACAD docs): AutoCAD 2000, AutoCAD LT 2000, and later releases do not support LZW-compressed TIFF files, with the exception of English language versions sold in the US and Canada.
If you have TIFF files that were created using LZW compression and want to insert them into a drawing you must save the TIFF files with LZW compression disabled.
