Draw raster row (CELL)
The row gives the map array row. The carray array provides the categories for each raster value in that row. This routine is called consecutively with the information necessary to draw a raster image from north to south. No rows can be skipped. All screen pixel rows which represent the current map array row are rendered. The routine returns the map array row which is needed to draw the next screen pixel row.

void D_setup | ( | int | clear | ) |
Graphics frame setup.
This is a high level D call. It does a full setup for the current graphics frame.
Note: Connection to driver must already be made.
Sets the source coordinate system to the current region, and adjusts the destination coordinate system to preserve the aspect ratio.
Performs a full setup for the current graphics frame:
If clear is true, the frame is cleared (same as running d.erase.) Otherwise, it is not cleared.

Sets the source coordinate system to its arguments, and if the fit argument is non-zero, adjusts the destination coordinate system to preserve the aspect ratio.
If clear is true, the frame is cleared (same as running d.erase). Otherwise, it is not cleared.

void D_setup_unity | ( | int | clear | ) |
Graphics frame setup.

draw a symbol at pixel coordinates
Draws a symbol (one of $GISBASE/etc/symbols/) to the active display. The starting x0,y0 coordinate corresponds to the center of the icon. The symbol must be pre-processed with S_stroke() before being sent to this function.

draw a symbol at pixel coordinates (alternate)
Draws a symbol (one of $GISBASE/etc/symbols/) to the active display. The same as D_symbol(), but it uses a primary and secondary color instead of line and fill color. The primary color is used to draw stroke lines (STRINGs) and as the fill color for polygons. The secondary color is used for polygon outlines.
Symb | The symbol name (e.g. basic/circle) |
x0 | The starting x display coordinate (pixel) |
y0 | The starting y display coordinate (pixel) |
