Package imageutil
Package imageutil contains code shared by image-related packages.
In the call graph viewer below, each node
is a function belonging to this package
and its children are the functions it
calls—perhaps dynamically.
The root nodes are the entry points of the
package: functions that may be called from
outside the package.
There may be non-exported or anonymous
functions among them if they are called
dynamically from another package.
Click a node to visit that function's source code.
From there you can visit its callers by
clicking its declaring func
token.
Functions may be omitted if they were
determined to be unreachable in the
particular programs or tests that were
analyzed.
func DrawYCbCr(dst *image.RGBA, r image.Rectangle, src *image.YCbCr, sp image.Point) (ok bool)
DrawYCbCr draws the YCbCr source image on the RGBA destination image with
r.Min in dst aligned with sp in src. It reports whether the draw was
successful. If it returns false, no dst pixels were changed.
This function assumes that r is entirely within dst's bounds and the
translation of r from dst coordinate space to src coordinate space is
entirely within src's bounds.
