The cross-reference table is one entry longer than the number of existing object: item zero is reserved and must not be used in any way.

         Images and :ref:`Pixmap` objects may contain resolution information provided as "dots per inch", dpi, in each direction (horizontal and vertical). When MuPDF reads an image from a file or from a PDF object, it will parse this information and put it in :attr:`Pixmap.xres`, :attr:`Pixmap.yres`, respectively. If it finds no meaningful information in the input (like non-positive values or values exceeding 4800), it will use "sane" defaults instead. The usual default value is 96, but it may also be 72 in some cases (e.g. for JPX images).

+  4. Font and :data:`fontsize` can freely vary within the same TextWriter. This can be used to let text with different properties appear on the same displayed line: just specify *pos* accordingly, and e.g. set it to :attr:`last_point` of the previously added item.
   5. You can use the *pos* argument of :meth:`TextWriter.fill_textbox` to set the position of the first text character. This allows filling the same textbox with contents from different :ref:`TextWriter` objects, thus allowing for multiple colors, opacities, etc.
   6. MuPDF does not support all fonts with this feature, e.g. no Type3 fonts. Starting with v1.18.0 this can be checked via the font attribute :attr:`Font.is_writable`. This attribute is also checked when using :ref:`TextWriter` methods.
