Autodesk Map and AutoCAD support for compressed TIFF format images.

The AutoCAD Map's MAPIINSERT (Map>Image>Insert...) command (or Insert>Image in AutoCAD, _IMAGE) supports only some of the compression schemes available in TIFF raster file format and doesn't support the CMYK color scheme. The following table lists the TIF V6/6.0 subformats (for monochrome .tif files) and their support in Autodesk Map 3D 2005/2006 and AutoCAD 2005/2006 (and 2007 and higher):

Format	File Size (sample)	Autodesk Support
Uncompressed TIFF	1.082.018 bytes	YES, full
Uncompressed multipage TIFF	2.164.036 bytes	Partial, only first page
ZIP-compressed TIFF	180.678 bytes	no (displays as 'gray noise'); YES since A2007
RLE-compressed TIFF (Huffman)	158.330 bytes	YES, full
Packbits-compressed TIFF	317.262 bytes	YES, full
LZW-compressed TIFF	195.794 bytes	no (US version only*); YES since A2007
JPG-compressed TIFF	3.719.647 bytes	no (displays as 'color noise'); YES since A2007
CCITT3-compressed TIFF (1Dim, Group 3 Fax)	160.938 bytes	YES, full
CCITT3-compressed TIFF (2Dim, Group 3 Fax)	132.719 bytes	no; YES since A2007
CCITT4-compressed TIFF (Group 4 Fax)	92.632 bytes	YES, full
16-bit grayscale TIFF	196.632 bytes	No, some yes, since 2012
48-bit color TIFF	329.632 bytes	No

NOTE: For the US versions installed from network deployment: copy the files ielzwdec80.dll and egifrd80.dll from AutoCAD CD '\ACADFeui\Program Files\Common Files\Autodesk Shared' to the 'C:\Program Files\Common Files\Autodesk Shared' folder.

You may also consider using ECW or SID compressed raster file formats in Map and higher AutoCAD versions. For raster file format conversion (incl. batch conversion) you can use e.g. the IrfanView freeware viewer (www.irfanview.com).
