LizardTech MrSID .SID File Description


The LizardTech MrSID filter imports .SID files.


File Description

The MrSID (pronounced Mister Sid) is an acronym that stands for multiresolution seamless image database. It is a file format developed and patented by LizardTech for encoding of georeferenced raster graphics. Unlike many other file formats, any rectangular region of the image can be quickly extracted from the file without decompressing the entire file. A region can be specified for import in the MrSID Import Options dialog, or the image can be imported as a read-only image. Each of these options decreases the import time for large MrSID files.
