Method
GdkPixbufPixbufscale
Declaration [src]
void
gdk_pixbuf_scale (
const GdkPixbuf* src,
GdkPixbuf* dest,
int dest_x,
int dest_y,
int dest_width,
int dest_height,
double offset_x,
double offset_y,
double scale_x,
double scale_y,
GdkInterpType interp_type
)
Description [src]
Creates a transformation of the source image src by scaling by
scale_x and scale_y then translating by offset_x and offset_y,
then renders the rectangle (dest_x, dest_y, dest_width,
dest_height) of the resulting image onto the destination image
replacing the previous contents.
Try to use gdk_pixbuf_scale_simple() first; this function is
the industrial-strength power tool you can fall back to, if
gdk_pixbuf_scale_simple() isn’t powerful enough.
If the source rectangle overlaps the destination rectangle on the same pixbuf, it will be overwritten during the scaling which results in rendering artifacts.
Parameters
dest-
Type:
GdkPixbufThe
GdkPixbufinto which to render the results.The data is owned by the caller of the method. dest_x-
Type:
intThe left coordinate for region to render.
dest_y-
Type:
intThe top coordinate for region to render.
dest_width-
Type:
intThe width of the region to render.
dest_height-
Type:
intThe height of the region to render.
offset_x-
Type:
doubleThe offset in the X direction (currently rounded to an integer).
offset_y-
Type:
doubleThe offset in the Y direction (currently rounded to an integer).
scale_x-
Type:
doubleThe scale factor in the X direction.
scale_y-
Type:
doubleThe scale factor in the Y direction.
interp_type-
Type:
GdkInterpTypeThe interpolation type for the transformation.
