|ContainerField||the container field to inspect|
Returns types or error.
DescriptionReturns the list of objects in the container field.
FileMaker stores a copy of the image in the container field as a JPEG if the image is not already of that type. That is why you will always see JPEG in the list of Types, even if the image in question is a PNG. This function will have "FILE" in the list of types if the image has File inserted into it.
Some of the allowed types include "TIFF", "PDF ", "PNGf", "GIFf", "BMPf", "EPS ", "PICT", "FILE" and "JPEG".
"ZLIB" is the type used by compressed containers.
