Hi WeiWooi,

I thought you were interested in tagged PDF documents, but I don’t think
that fits in your explanation above.

You mean to have vector images with text inside, don’t you?

I don’t think pandoc (or LaTeX) has anything to do here with the images.
Bitmap images cannot contain text. They only contain text as bitmaps.
OCR software doesn’t read that, but only recognize patterns and render
them as text.

If you want text in your images, you will need to generate them as
vector images in a format that also allows text inside (either SVG,
PostScript, EPS or PDF).

I hope it helps,

Pablo
