PCD Source File Format

All plotter device characteristics are specified using the following format:

keyword { value }

where keyword is one of the PCD source file keywords and value is a quoted string or numeric value. For example, the following statement specifies that the plotter supports color:


ColorCap {1}

Keywords are described in the following table.

Quoted string representing a displayable device name (31 characters max.)

"HPGL/2 Plotter"

DevicePelsDPI

One DWORD-sized value representing the device's effective DPI. For more information see the upDevicePelsDPI member of GDIINFO.

The default is zero, causing GDI to calculate a value.

DeviceSize

Two DWORD-sized values representing maximum paper size, in x and y coordinates of 1/1000 mm units.

A y value of 25400 (1 inch) or less indicates the device accepts variable paper lengths.

FormInfo

A form description for each form supported by the plotter. For more information, see the Form Descriptions section that follows this Table.

None.

HTPatternSize

One of the HT_PATSIZE_-prefixed constants that identify standard halftoning patterns.

InitString

Quoted C-language string representing commands sent to the printer by the driver's DrvStartPage function.

NULL string.

MaxCopies

Maximum number of copies per page that the device can render.

1

MaxPens

Number of pens (32 max.)

8

MaxPolygonPts

Maximum number of points to define a polygon to be stroked or filled.

128

MaxQuality

Number of quality levels (4 max.)

4

MaxScale

Maximum scale size. 0-10000 (100 is 100%)

100

Two DWORD-sized values representing the paper tray width and height, in 1/1000 mm units.

{-1,
-1}

PlotDPI

Two DWORD-sized values representing a pen plotter's x and y resolution, in dots per inch.

{1016,
1016}

PlotPenData

A pen description for each pen. For more information, see the Pen Descriptions section that follows this Table.

None.

0=Byte alignment is not required.

0

RasterCap

1=Raster device

0=Pen device

0

RasterDPI

Two DWORD-sized values representing x and y resolution, in dots per inch.

For raster plotters, this is the raster resolution.

For pen plotters, this is the ideal resolution the GDI supplies to an application.

{300,
300}

RollFeedCap

1=Device has roll paper source.

0=No support.

0

ROPLevel

ROP_LEVEL_0 = No RasterOp support.

ROP_LEVEL_1 = Rop1 support.

ROP_LEVEL_2 = Rop2 support.

ROP_LEVEL_3 = Rop3 support.

ROP_LEVEL_0

RTLMonoEncode5

1=HP Raster Transfer Language (RTL) Monochrome Compression Mode 5 is supported.

0=No support.

0

RTLMonoFixPal

RTL Monochrome palette only.

0=White, 1=Black

0

RTLMonoNoCID

1=In RTL Mono mode, CID commands are not required.

0=In RTL Mono mode, CID commands are required.

0

RTLNoDPIxy

1=RTL DPI X,Y move commands are not supported.

0=These commands are supported.

0

TransparentCap

Pen Descriptions

Each pen description must have the following format:

PlotPenData {Pen Number, Color}

where Pen Number identifies the pen's slot number and Color is a PC_IDX_-prefixed color identifier. Following are example pen descriptions:


PlotPenData {1, PC_IDX_WHITE}
PlotPenData {2, PC_IDX_BLACK}
PlotPenData {3, PC_IDX_RED}

Form Descriptions

Each form description must have the following format:

FormInfo {"Form Description", Width, Length, Left Margin, Top Margin, Right Margin, Bottom Margin}

where Form Description is a string describing the form, Width and Length specify the form size in 1/1000 mm units, and the margins are also specified in 1/1000 mm units. Following are three examples:


FormInfo {"Roll Paper 24 in",    609600,      0, 0, 0, 0, 0}
FormInfo {"ANSI A 8.5 x 11 in",  215900, 279400, 0, 0, 0, 0}
