Here is another example generated from the same book table's PDF page
definition. This time the grid is shown, but no colors.
A note about fonts used
All the text we see in the PDF schema is drawn using a specific font. phpMyAdmin
3.1.x uses the DejaVuSans font ( http://dejavu.sourceforge.net ), which covers a
wide range of characters.
For actual PDF generation, phpMyAdmin relies on the tcpdf library
( http://tcpdf.sourceforge.net ), which itself is an adaptation of the fpdf library
( http://www.fpdf.org ). These libraries have two ways of using fonts—embedded
and not embedded. Embedded fonts produce a bigger PDF file because the whole
font is included in the PDF. This is the default option chosen by phpMyAdmin
because the library does not depend on the presence of a specific TrueType font in
the client operating system.
The fonts are located in libraries/tcpdf/font under the main
phpMyAdmin directory.
To use a different font file, we must first add it to the library (tools are present in the
original tcpdf kit and a tutorial is available on the http://www.fpdf.org website)
and then modify phpMyAdmin's pdf_schema.php source code.
