Is there any way to extrace an embedded Type 3 fonts in my own PDF?

[Weijia5EAF]

I have made a PDF in which there is my custom font outputted with Metafont in the Type 3 bitmap format. Now the source Metafont code is lost and the only copy of the font lies in the PDF. Are there any way to extract this bitmap font?

For the information, this is the PDF that I generated:

Hi Weijia,

I do not know how this might be done and I strongly doubt it could be done. If this were possible, it would violate every copywriter protection that font industries depend upon.

What I suggest you do is to take a screenshot of the font in your PDF and go to "Whatthefont.com." From there you can place your screenshot and it will find the best match. Then you can buy a new copy and you'll be good to go.

Good luck!

I am not trying to extract an existing font, but my own experimental font built with Metafont program. Theoretically the output (pdfTeX) would not impose copywrite protection on such font as well.

Type 3 fonts aren't really font files like TTF, OTF files. They are really collections of PDF graphics in a bundle. Nothing you can extract for reuse.

The only font that is actually embedded in your file is the CM10 (Computer Modern) font used for your page number.

Your Type 3 exist only as the bitmap images generated in the file at that size and those characters, nothing else. If you are looking for your original code to create these, it's not there.

You can't extract fonts from a PDF document, not with Acrobat anyway.
