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.
clear | 1 to clear frame (visually and coordinates) |

) |
Sets source coordinate system.
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.
Sets the source coordinate system to match the destination coordinate system, so that D_* functions use the same coordinate system as R_* functions.
If clear is true, the frame is cleared (same as running d.erase). Otherwise, it is not cleared.
clear | non-zero code to clear the frame |
