Description

TGraphicField represents a graphics field in a dataset.

TGraphicField encapsulates the fundamental behavior common to fields that hold graphic data. Graphics fields are a form of binary large object (BLOB) field where the data includes a BLOB header describing the encoding of the graphical value.

If you use the Fields editor at design time to create a persistent field component for the graphics field, you can access it by name at runtime. When using dynamic field components, you can access the TGraphicField instance using the dataset's Fields property or FieldByName method.
