Image Analyzer

Overview

The Image Analyzer is a replacement for the Image Graph in CCStudio 3.x and earlier. It has been integrated starting with CCStudio v4.

The main goal for the Image Analyzer is to:

• Address known issues with the existing CCStudio Image Graph
• Add support for more formats
  • Extensible to support new user defined image formats
• Various usability enhancements

The Image Analyzer is currently available with all releases newer than CCSv4.

FAQ

Question: Can you save the image to the host PC in a file?

Answer: This is currently not possible with Image Analyzer. However, you can use the Memory View’s Save feature to dump target memory to a file. Save it either as Raw or Coff format since Image Analyzer cannot read the .dat format.
