Use
Use in params and variables blocks to define the data type of a parameter or variable. The data type can be selected when defining fields, global variables, and component variables.
Description
Use the image data type for fields that contain images from the database, glyphs, disk files, or third-party filters.
No arithmetic operations can be applied to this kind of data.
It is not possible to directly compare two
parameters, variables, or fields that use the data type raw or
image—they will always evaluate to True. An alternative is to
calculate and compare a hash of the data. For more information, see Comparing raw or image Data.
