Use Image Profile to extract helpful information from images. The information includes base data, like the image's size and number of channels; Exif data, which is metadata; and a summary of helpful metrics for each channel in the images, like the total number of pixels.

Tool Components

Image Profile has 2 anchors:

  • I anchor: Use this anchor to input the images you want to profile. 
  • O anchor: Use this anchor to pass the images you've profiled, as well as their profile information, downstream.

Configure the Tool

To use this tool...

  1. Drag the tool onto the canvas.
  2. Select the column that has the image you want to create a profile for.
  3. Choose what profiles to create. You can Select All profiles or Only Include Selected Profiles.
  4. Run the workflow.
