Can I save an existing image to LizardTech’s MrSID or ER Mapper’s ECW format?
While AutoCAD Raster Design 2009 does not currently allow saving to MrSID or ECW image format, you can directly edit these MrSID and ECW images. By saving the changes or edits (such as cropping and highlighting areas of interest) to JPEG 2000 format, you retain the multiresolution advantages of small file size and fast performance with high visual image quality.
