Image_Read_Multi

Node​

Node Description​

Ingests and processes an image file

Takes multiple images as input, processes via user-defined function, and stores a dict of processed images to the storage bucket

Node Attributes​

  • input_multi_image
    • File extension for valid image files submitted. For example, filling in this attribute with "*.bmp" will only allow files with the extension .bmp to be uploaded.
  • output_table_image_info
    • Metadata table displayed on Table Head in Ganymede UI.

Notes​

In the execute function, returning NodeReturn(tables_to_upload={'image_info': df}) would render the DataFrame df in the Flow Editor if Table Head visualization is enabled.

Example​

The example Node configuration captures PNG files and would render image_info_tbl in Flow Editor if Table Heads are enabled

  • image: *.png
  • image_info: image_info_tbl
