Exporting complete paperspace into png or pdf

[littlekittel]

Hi all,

I am trying to export a complete paperspace into a png or pdf. Everything you see in the paperspace when opening the dxf.
So far I found documentation about exporting certain regions of the model space but not for entire paperspaces.
Is there anything available out of the box?
I guess an alternative could be to export all viewports and than stitch them back together?

Thank you!

The Frontend class of the drawing add-on can export paperspace layouts.

def export(filepath: pathlib.Path, layout_names=("Model",), scale=1):
    doc = ezdxf.readfile(filepath)
    for layout_name in layout_names:
        outname = pathlib.Path(filepath.stem + f"-[{layout_name}]" + ".pdf")
        print(outname)
        if layout_name == "Model":
            dxf_layout = doc.modelspace()
            page = layout.Page(
                0,  # auto-detect
                0,  # auto-detect
                layout.Units.mm,  # 1 drawing unit = 1mm

            settings = layout.Settings(scale=scale)
        else:
            try:
                dxf_layout = doc.paperspace(layout_name)
            except KeyError:
                print(f"Layout '{layout_name}' not found")
                continue
            page = layout.Page.from_dxf_layout(dxf_layout)
            settings = layout.Settings(
                fit_page=False,
                scale=dxf_layout.get_plot_unit_scale_factor() * scale,
            )

        backend = pymupdf.PyMuPdfBackend()
        config = Configuration(
            background_policy=BackgroundPolicy.WHITE,
            color_policy=ColorPolicy.MONOCHROME_LIGHT_BG,
            lineweight_policy=LineweightPolicy.RELATIVE,
        )

        Frontend(RenderContext(doc), backend, config=config).draw_layout(dxf_layout)
        pdf_bytes = backend.get_pdf_bytes(page, settings=settings)
        outname.write_bytes(pdf_bytes)


if __name__ == "__main__":
    export(pathlib.Path(r"A_000217.dxf"), ["Model", "Layout1"])

This script creates the two PDFs:

A_000217-[Model].pdf

A_000217-[Layout1].pdf (arbitrary clipping polygons seem to work now)

A_000217.zip

Fixed incompatibility with newer PyMuPDF versions.

This works great, thank you!
How is the arbitrary polygon applied on the second layout?

[mozman]

It's a VIEWPORT with a polygonal clipping path.

Hi all, Continuing this thread since it is relevant to my query. In the image below, you see a paperspace of a file. There are certain elements frozen in different viewports. I am trying to plot this paperspace as seen. Is there a way to plot the layout, considering the frozen layers? At the moment, plotting this paperspace shows all the elements in all of the viewports regardless of the frozen layers.

[mozman]

The individual state of frozen layers in viewports is not supported.

UPDATE: The feature is implemented but doesn't work for this example, can you post your (zipped) DXF file?

[mozman]

I did a test and it works:

ezdxf view command:

Added new example file for testing: https://github.com/mozman/ezdxf/blob/master/examples_dxf/viewport_frozen_layers.dxf
