Function cairo:font-matrix
Lambda Listcairo:font-matrix (cr matrix) SyntaxArgumentsDetails The cairo:font-matrix function stores the current font matrix into matrix and returns the cairo:matrix-t instance. The (setf cairo:font-matrix) function sets the current font matrix. The font matrix gives a transformation from the design space of the font (in this space, the em-square is 1 unit by 1 unit) to user space. Normally, a simple scale is used, see the cairo:set-font-size function, but a more complex font matrix can be used to shear the font or stretch it unequally along the two axes. | See also |
