DevOpenDC Parameter - lType

lType (LONG) - input

Type of device context:

OD_QUEUED

A device, such as a printer or plotter, for which output is to be queued.

Certain restrictions apply for this device type;

OD_DIRECT
A device, such as a printer or plotter, for which output is not to be queued.
OD_INFO
A device, such as a printer or plotter, but the device context is used only to retrieve information (for example, font metrics). Drawing can be performed to a presentation space associated with such a device context, but no output medium is updated.
OD_METAFILE
The device context is used to write a metafile. The presentation page defines the area of interest within the picture in the metafile. See OD_METAFILE_NOQUERY.

Certain restrictions apply for this device type;

OD_METAFILE_NOQUERY
The device context is used to write a metafile.

Functionally, this device type is the same as OD_METAFILE, except that querying of attributes is not allowed with a presentation space while it is associated with an OD_METAFILE_NOQUERY device context. If querying of attributes is not required, OD_METAFILE_NOQUERY should be used in preference to OD_METAFILE, since it gives improved performance.

Certain restrictions apply for this device type;

OD_MEMORY
A device context that is used to contain a bit map. The hdcComp parameter identifies a device with which the memory device context is to be compatible.
