Printing & Plotting

Plot the drawing to a printer, to PDF, or to a raster image, and manage named plot regions.

Outputs

• Printer / PDF — the CadPrint* family drives the plot pipeline to a device or a PDF file, honouring the plot area, scale and rotation.
• Raster image — CadExportImage renders the drawing (or a region) to an image file at a chosen pixel size — useful for thumbnails and previews.

Plot regions

The CadPrnRect* / rectangle-print family defines and queries named plot rectangles — rectangular areas of model space earmarked for output, each with its own scale and paper mapping. This mirrors Vecad's print-region model so a migrating host keeps its plotting UI.

/* render the current view region to a PNG at 1600×1200 */
