cairo_mesh_pattern_get_corner_color_rgba.Rd
Gets the color information in corner corner_num of patch patch_num for a mesh pattern.
cairo_mesh_pattern_get_corner_color_rgba( pattern, patch_num, corner_num, red, green, blue, alpha )
pattern | [ |
---|---|
patch_num | [ |
corner_num | [ |
red | [ |
green | [ |
blue | [ |
alpha | [ |
[int
]
patch_num can range from 0 to n-1 where n is the number returned by cairo_mesh_pattern_get_patch_count().
Valid values for corner_num are from 0 to 3 and identify the corners as explained in cairo_pattern_create_mesh().
Return value: %CAIRO_STATUS_SUCCESS, or %CAIRO_STATUS_INVALID_INDEX if patch_num or corner_num is not valid for pattern. If pattern is not a mesh pattern, %CAIRO_STATUS_PATTERN_TYPE_MISMATCH is returned.
