Filter is used to indicate what filtering should be applied when reading pixel values from patterns.
See Cairo::SurfacePattern::set_filter() for indicating the desired filter to be used with a particular pattern.
|
explicit |
Create a C++ wrapper for the C instance.
This C++ instance should then be given to a RefPtr.
cobject | The C instance. |
has_reference | Whether we already have a reference. Otherwise, the constructor will take an extra reference. |
|
override |
|
static |
Create a new Cairo::Pattern for the given surface.
Filter Cairo::SurfacePattern::get_filter | ( | ) | const |
Gets the current filter for a pattern.
See Cairo::Filter for details on each filter.
Gets the surface associated with this pattern.
void Cairo::SurfacePattern::set_filter | ( | Filter | filter | ) |
Sets the filter to be used for resizing when using this pattern.
See Cairo::Filter for details on each filter.
Note that you might want to control filtering even when you do not have an explicit Cairo::Pattern object, (for example when using Cairo::Context::set_source_surface()). In these cases, it is convenient to use Cairo::Context::get_source() to get access to the pattern that cairo creates implicitly.
