Description

-

The current transformation matrix, ctm, is a -two-dimensional affine transformation that maps all coordinates and other -drawing instruments from the user space into the -surface's canonical coordinate system, also known as the device -space.

-
-
-

Functions

-
-

cairo_translate ()

-
void
-cairo_translate (cairo_t *cr,
-                 double tx,
-                 double ty);
-

Modifies the current transformation matrix (CTM) by translating the -user-space origin by (tx -, ty -). This offset is interpreted as a -user-space coordinate according to the CTM in place before the new -call to cairo_translate(). In other words, the translation of the -user-space origin takes place after any existing transformation.

-
-

Parameters

-
----- - - - - - - - - - - - - - - - - - -

cr

a cairo context

 

tx

amount to translate in the X direction

 

ty

amount to translate in the Y direction

void
-cairo_scale (cairo_t *cr,

-             double sy);
-

Modifies the current transformation matrix (CTM) by scaling the X -and Y user-space axes by sx - and sy - respectively. The scaling of -the axes takes place after any existing transformation of user -space.

cr

a cairo context

 

sx

scale factor for the X dimension

cairo_rotate ()

-
void
-cairo_rotate (cairo_t *cr,
-              double angle);
-

Modifies the current transformation matrix (CTM) by rotating the -user-space axes by angle - radians. The rotation of the axes takes -places after any existing transformation of user space. The -rotation direction for positive angles is from the positive X axis -toward the positive Y axis.

-
-

Parameters

angle

angle (in radians) by which the user-space axes will be -rotated

Modifies the current transformation matrix (CTM) by applying -matrix - as an additional transformation. The new transformation of -user space takes place after any existing transformation.
