Description
Bitmap displays on Mac are actually PDFs, not PNGs as in Windows. I have been doing this because Office on Mac supports inserting PDFs, and PDFs don't suffer from resolution issues.
Under the hood, Office actually stores them as EMF files (despite not supporting insertion of EMF!!) which you can see by unzipping the .pptm file, but there seems to be a bug with this conversion. We noticed that such displays appeared cropped when viewed on Windows in versions of IguanaTex prior to v1.60. Interestingly, PDFs generated with LaTeXiT do not suffer from this issue:
In IguanaTex v1.60, as a temporary workaround, I am adding a bigger margin around the content when cropping the PDF. The downside of that is that the size of the display does not exactly match the size of the visible content, and also that there is still a discrepancy between the size of the display as viewed on Mac vs Windows.
I have tried various options when cropping with Ghostscript, to no avail so far. I have reached out to LaTeXiT's author to ask for advice, as he's clearly doing something better than Ghostscript.
I will use this issue to keep everyone updated on my progress. Please feel free to chime in if you have suggestions.
