I often copy-paste things from LatexIt or OmniGraffle into Mathematica notebooks. The results are GraphicsData objects which don't render in the Wolfram Cloud. Is there an easy work-around?

Since bitmaps render properly, perhaps there's some way to automatically convert all GraphicsData objects in the notebook into bitmaps?

Here's example notebook:

  • $\begingroup$ It's not a bug per se, just a really old Mac behavior. Those programs are emitting PDF to the clipboard instead of a bitmap. And the Mac FE was the only one really capable of handling that particular format. For instance, the Windows FE is not capable of rendering those cells either. $\endgroup$ – ihojnicki Dec 19 '19 at 14:03

I don't know how to convert the given GraphicsData objects into vector graphics, but you can use Rasterize to convert them into bitmaps. Here is a function that does this:

rasterizeGraphicsData[Cell[g:GraphicsData["PDF", __], "Graphics", OptionsPattern[Cell]]] := Module[{size},
    size = OptionValue[Cell, ImageSize];
    Cell[
        BoxData @ ToBoxes @ Rasterize[
            Cell[g, "Graphics"], 
            ImageSize -> size,
            RasterSize -> 5 size
        ],
        "Output"
    ]
]

Now, we need to apply the above function on each of the GraphicsData cells. We can do that with the following function:

convertNotebookGraphicsData[nb_] := With[
    {cells = Cells[nb, CellStyle -> "Graphics"]},
    NotebookWrite[#, rasterizeGraphicsData @ NotebookRead[#]]& /@ cells
]

Use Notebooks to find the notebook object to process and then use convertNotebookGraphicsData[nb] where nb is the NotebookObject corresponding to your notebook.
