Canvas X Draw contains important features that allow you to analyze an image’s pixel values and measure various image properties: Image Data Viewer tool, View Data command, and Image Measurement command.
You can quickly view raw data within an image object using either the Image Data Viewer tool or View Data command. These tools are designed so you can quickly view image data “on the fly”. In addition, you can copy this data to a .txt file or spreadsheet application for further analysis.
