Members

DrvEnablePDEV
Pointer to a function that returns a PDEV structure, which is a logical representation of a physical display device, to the GDI.
DrvDisablePDEV
Pointer to a function that notifies the driver that the GDI no longer needs a particular display device.
DrvEnableSurface
Pointer to a function that creates a drawing surface and associates it with a PDEV.
DrvDisableSurface
Pointer to a function that notifies the driver that the GDI no longer needs a particular drawing surface.
DrvCreateDeviceBitmap
Pointer to a function that creates and manages bitmaps.
DrvDeleteDeviceBitmap
Pointer to a function that deletes a device bitmap.
DrvRealizeBrush
Pointer to a function that creates a brush with parameters that are specified by the GDI.
DrvStrokePath
Pointer to a function that renders a drawing path.
DrvFillPath
Pointer to a function that fills a drawing path with a brush.
DrvPaint
Pointer to a function that paints a specified region with a brush.
DrvBitBlt
Pointer to a function that performs general bit-block transfer, with clipping and masking.
DrvCopyBits
Pointer to a function that sends a GDI-created print band to a printer driver.
DrvAnyBlt
Pointer to a function that performs bit-block transfer, with stretching or transparency.
DrvTransparentBlt
Pointer to a function that performs bit-block transfer, with transparency.
DrvSetPalette
Pointer to a function that sets the display device's palette.
DrvSetPointerShape
Pointer to a function that sets the pointer to a new shape and updates the display.
DrvMovePointer
Pointer to a function that moves the pointer with a guarantee that the GDI will not interfere with the operation.
DrvGetModes
Pointer to a function that lists the display modes that are supported by the display device.
DrvRealizeColor
Pointer to a function that maps an RGB color onto the closest available color that is supported by the device.
DrvGetMasks
Pointer to a function that gets the color masks for the display device's current mode.
DrvUnrealizeColor
Pointer to a function that maps a color in the display device's format onto an RGB value.
DrvContrastControl
Pointer to a function that enables software adjustment of the display hardware's contrast.
DrvPowerHandler
Pointer to a function that handles POWER_UP and POWER_DOWN notifications.
DrvEndDoc
Pointer to a function that sends any control information that is needed to finish printing a document.
DrvStartDoc
Pointer to a function that sends any control information that is needed to start printing a document.
DrvStartPage
Pointer to a function that sends any control information that is needed to start printing a new page.
DrvEscape
Pointer to a function that retrieves information from a device that is not available in a device-independent DDI. This function is the same as Windows-based desktop platforms, except that Windows CE does not support the DrvDrawEscape function.
DrvGradientFill
Pointer to a function that fills a rectangular region with a background color that is interpolated from color values specified at the vertices.
