Méthode tkinter.PhotoImage.copy_replace

Signature de la méthode copy_replace

def copy_replace(self, sourceImage, *, from_coords=None, to=None, shrink=False, zoom=None, subsample=None, compositingrule=None) 

Description

help(PhotoImage.copy_replace)

Copy a region from the source image (which must be a PhotoImage) to
this image, possibly with pixel zooming and/or subsampling.  If no
options are specified, this command copies the whole of the source
image into this image, starting at coordinates (0, 0).

The FROM_COORDS option specifies a rectangular sub-region of the
source image to be copied. It must be a tuple or a list of 1 to 4
integers (x1, y1, x2, y2).  (x1, y1) and (x2, y2) specify diagonally
opposite corners of the rectangle.  If x2 and y2 are not specified,
the default value is the bottom-right corner of the source image.
The pixels copied will include the left and top edges of the
specified rectangle but not the bottom or right edges.  If the
FROM_COORDS option is not given, the default is the whole source
image.

The TO option specifies a rectangular sub-region of the destination
image to be affected.  It must be a tuple or a list of 1 to 4
integers (x1, y1, x2, y2).  (x1, y1) and (x2, y2) specify diagonally
opposite corners of the rectangle.  If x2 and y2 are not specified,
the default value is (x1,y1) plus the size of the source region
(after subsampling and zooming, if specified).  If x2 and y2 are
specified, the source region will be replicated if necessary to fill
the destination region in a tiled fashion.

If SHRINK is true, the size of the destination image should be
reduced, if necessary, so that the region being copied into is at
the bottom-right corner of the image.

If SUBSAMPLE or ZOOM are specified, the image is transformed as in
the subsample() or zoom() methods.  The value must be a single
integer or a pair of integers.

The COMPOSITINGRULE option specifies how transparent pixels in the
source image are combined with the destination image.  When a
compositing rule of 'overlay' is set, the old contents of the
destination image are visible, as if the source image were printed
on a piece of transparent film and placed over the top of the
destination.  When a compositing rule of 'set' is set, the old
contents of the destination image are discarded and the source image
is used as-is.  The default compositing rule is 'overlay'.
