1.23.9rc1: module 'fitz.mupdf' has no attribute 'fz_copy_pixmap_rect'

[cbm755]

Description of the bug

I tried the rebased fitz for the first time (sorry have been lax about following that). My test suite dies with this:

  File "/builds/plom/plom/plom_server/Finish/services/soln_source.py", line 129, in take_solution_source_pdf_from_upload
    self._create_solution_images(version, doc)
  File "/builds/plom/plom/plom_server/Finish/services/soln_source.py", line 148, in _create_solution_images
    soln_img.copy(pix, pix.irect)
  File "/usr/local/lib/python3.10/dist-packages/fitz/__init__.py", line 9753, in copy
    mupdf.fz_copy_pixmap_rect(pm, src_pix, JM_irect_from_py(bbox), mupdf.FzDefaultColorspaces(None))
AttributeError: module 'fitz.mupdf' has no attribute 'fz_copy_pixmap_rect'

How to reproduce the bug

For now, its just this CI output:

https://gitlab.com/plom/plom/-/jobs/5863036742

If I get a chance later, I will try to narrow it down... but I thought it might be useful report first and track later.

Pretty far from a MWE, but the code that is triggering this is:

            # see https://pymupdf.readthedocs.io/en/latest/recipes-images.html#how-to-use-pixmaps-gluing-images
            # get an image for each page - note fitz pages are 0-indexed.
            pix_list = [doc[pg - 1].get_pixmap() for pg in sqs_obj.pages]
            total_w = sum([X.width for X in pix_list])
            max_h = max([X.height for X in pix_list])
            # creage a dest image on which to tile these images - with given max height and total width.
            soln_img = fitz.Pixmap(
                pix_list[0].colorspace, (0, 0, total_w, max_h), pix_list[0].alpha
            )
            # concat the images together into the dest image.
            starting_x = 0
            for pix in pix_list:
                pix.set_origin(starting_x, 0)
                soln_img.copy(pix, pix.irect)     # <---  exception here
                starting_x += pix.width

I checked and it does seem to be using the RC of PyMuPDFb as well:

Thanks for this.

Yes, you're quite right, it's missing from MuPDF's public API and thus breaking the rebased implementation.

Am working on a fix now.

[julian-smith-artifex-com]

This is fixed in release candidate 1.23.9rc2; see: #2996

[cbm755]

Confirmed fixed at my end. Closing.

[julian-smith-artifex-com]

Reopening until the fix is in a full release.

[julian-smith-artifex-com]

Fixed in 1.23.9.
