ImgSource_GetList({protocol}) ➔ sourceList

protocol	Text	Restrict image sources to this protocol.
sourceList	Object	The result image source list represented by a 4D object.

Return a list of the available image acquisition sources as a 4D object.

Image Acquisition Protocols

Key	Description
TWAIN	The TWAIN standard. Available on all platforms, supported mostly by scanners.
IC	Image Capture, the standard image acquisition framework on macOS.

The names of the properties in the returned object are the ID’s of the sources. The value of each property is an object containing information about the source. The properties of the source information object are described in the following table.

Image Source Properties

Note

This method is a wrapper for the ImgSrc_GetList_JSN plug-in method. It returns a 4D object instead of a JSON object serialization.
