Method

GdkPixbufPixbufcomposite

Declaration [src]

void
gdk_pixbuf_composite (
  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,
  int overall_alpha
)

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.

This gives an image in the coordinates of the destination pixbuf. The rectangle (dest_x, dest_y, dest_width, dest_height) is then alpha blended onto the corresponding rectangle of the original destination image.

When the destination rectangle contains parts not in the source image, the data at the edges of the source image is replicated to infinity.

Parameters

dest

Type: GdkPixbuf

The GdkPixbuf into which to render the results.

The data is owned by the caller of the method.

dest_x

Type: int

The left coordinate for region to render.

dest_y

Type: int

The top coordinate for region to render.

dest_width

Type: int

The width of the region to render.

dest_height

Type: int

The height of the region to render.

offset_x

Type: double

The offset in the X direction (currently rounded to an integer).

offset_y

Type: double

The offset in the Y direction (currently rounded to an integer).

scale_x

Type: double

The scale factor in the X direction.

scale_y

Type: double

The scale factor in the Y direction.

interp_type

Type: GdkInterpType

The interpolation type for the transformation.

overall_alpha

Type: int

Overall alpha for source image (0..255).
