This class is used to create objects that contain data describing image properties

Syntax

class PropertyItem {
  public:
    PROPID          id;
    ULONG           length;
    WORD            type;
    UNALIGNED VOID* value;
};

Data Members

  • id
    A PROPID value identifying the type of property.

    This value should be one of the PropertyTag Values.

  • length
    A ULONG value identifying the length, in bytes, of the data associated with the property identified by id.

  • type
    A WORD value identifying the data type for the property's value.

    This value should be one of the PropertyTagType Values.

  • value
    An UNALIGNED VOID pointer to an array of data values associated with the property identified by id. Function and method calls that use this structure as a parameter can fail if the value pointer is not unaligned.
