Method

VipsImagedraw_flood

Declaration [src]

int
vips_draw_flood (
  VipsImage* image,
  double* ink,
  int n,
  int x,
  int y,
  ...
)

Description [src]

Optional arguments:

test: test this image
equal: fill while equal to edge
left: output left edge of bounding box of modified area
top: output top edge of bounding box of modified area
width: output width of bounding box of modified area
height: output height of bounding box of modified area

Flood-fill image with ink, starting at position x, y. The filled area is bounded by pixels that are equal to the ink colour, in other words, it searches for pixels enclosed by an edge of ink.

If equal is set, it instead searches for pixels which are equal to the start point and fills them with ink.

Normally it will test and set pixels in image. If test is set, it will test pixels in test and set pixels in image. This lets you search an image (test) for continuous areas of pixels without modifying it.

left, top, width, height output the bounding box of the modified pixels.

ink is an array of double containing values to draw.

Parameters

`ink`	An array of `double`
	Value to draw.
	The length of the array is specified in the `n` argument.
	The data is owned by the caller of the function.
`n`	`int`
	Length of ink array.
`x`	`int`
	Centre of circle.
`y`	`int`
	Centre of circle.
`...`
	`NULL`-terminated list of optional named arguments.

Return value

Returns:	`int`
	0 on success, or -1 on error.
