PDF text to curve (Xu Lao in, Help!!!) ）
I'm working on this. PHP generates a PDF function, the PDF is mainly text and pictures.
And then surf the internet for a bit, currently using Tcpdf library.
The resulting PDF font should already be embedded in the PDF, as the font generation is also all right, and the different system environments can be opened.
But the printer is not recognized, saying that there is no font.
So I was wondering whether to turn the PDF into a curve, so that the printer recognizes the picture, it should be OK.
How does PHP turn the PDF text??? There is no way to solve, thank you very much. PDF Font

Turns out to be complicated, with Adobe's Warp:

First of all, I know there is a tcpdf, but I have not used (think he is too large)
I now use the fpdf, the public is weaker than the tcpdf, but it is convenient for me to expand.
Back to the point, the PDF font is a series of PS instructions, you can intercept them out with the Tcpdf::_out method output can be
I generally use Photoshop to convert graphics into path files, extracting the PS instruction to fpdf using the

For Tcpdf's Apidoc, I didn't find the function description of _out?
Can be a little more detailed about tcpdf call PS instruction content, or have a similar article, thank you ~
Also, to use fpdf words, I still do not very much, my own research to expand these studious?

Tcpdf::_out is an internal method that is not written in the document
The core of Tcpdf is fpdf, and _out is the internal method of fpdf.
These two categories are ultimately written in the PDF document buffer by _out
Of course they (especially tcpdf) offer a high-level approach
After you have obtained the curve data, of course, you can use curve, Curvev, Curveh method to draw the curve
