Hi, have you had any progress with this issue?
We'd really like to know if this is an issue with the SynPDF library or the library that handles the equation metafile creation

Hi, so it seems somewhat better. However the symbols being used are not the correct ones.
It seems like there might still be an indexing issue.
It's currently looking like this:

And it should look like this:

Note: This second image is what is drawn when I export the equation as a bitmap.

Hi, sorry for the late reply.
Of course, here's WeTransfer link a zip with 2 EMF equations. I've confirmed they're correctly written.

The original metafile is created by another library I'm using that takes a LaTeX equation syntax and then returns it as a TMetafile.
It can also return it as a bitmap file which is rendered correctly on the canvas with no issues but is significantly heavier.
What seems to be happening is that the specific math symbols are not being recognized (like the integrals, infinite, stylized x an y symbols, etc...).
However, since the TVCLCanvas is a TCanvas (the same as the TForm canvas), I assumed that there would be no difference in the rendering between the both of them.
It seems like the symbols have the correct size (because I can select the "text" when visualizing the resulting PDF) but the rendering process doesn't know what to do with each symbol's "canvas".

Hi, I'm currently working on an internal project where I have to generate some PDF files. Currently I'm trying to draw some TMetafile objects on a the report canvas but I'm having some issues.
Basically when I tell the report canvas to draw my TMetafile it appears on the finished file with what appears to be some formatting errors. However, I know that the TMetafile object in question has been correctly created and formatted because when I use my application's form canvas (which is also a TCanvas object) it renders the TMetafile flawlessly.
I've tried a number of things including:
- Using the Draw function of the TVCLCanvas and TPdfCanvas;
- Using the RenderMetafile of the TVCLCanvas;
- Changing the TVCLCanvas to a TMetafileCanvas;
To be clear, I can draw the metafile but it is rendered with errors. Has anyone had this issue? I'm a little lost to be honest.
P.S: Unrelated but if anyone knows of a good library that can help me generate tables (like an excel table) into a PDF document I'd be much obliged;
