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.
This tool is part of Alteryx Intelligence Suite. Intelligence Suite requires a separate license and add-on installer to Designer. After you install Designer, install Intelligence Suite and start your free trial.
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.
