Constructor

VipsImagexyz

Declaration [src]

int
vips_xyz (
  VipsImage** out,
  int width,
  int height,
  ...
)

Description [src]

Create a two-band uint32 image where the elements in the first band have the value of their x coordinate and elements in the second band have their y coordinate.

You can make any image where the value of a pixel is a function of its (x, y) coordinate by combining this operator with the arithmetic operators.

Set csize, dsize, esize to generate higher dimensions and add more bands. The extra dimensions are placed down the vertical axis. Use vips_grid() to change the layout.

::: tip “Optional arguments” * csize: gint, size for third dimension * dsize: gint, size for fourth dimension * esize: gint, size for fifth dimension

::: seealso vips_grey(), vips_grid(), vips_identity().

Parameters

`out`	`VipsImage`
	Output image.
	The argument will be set by the function.
	The called function takes ownership of the data, and is responsible for freeing it.
`width`	`int`
	Horizontal size.
`height`	`int`
	Vertical size.
`...`	`none`
	`NULL`-terminated list of optional named arguments.

Return value

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