Method

CoglTextureset_region

Declaration [src]

gboolean
cogl_texture_set_region (
  CoglTexture* texture,
  int src_x,
  int src_y,
  int dst_x,
  int dst_y,
  unsigned int dst_width,
  unsigned int dst_height,
  int width,
  int height,
  CoglPixelFormat format,
  unsigned int rowstride,
  const uint8_t* data
)

Description [src]

Sets the pixels in a rectangular subregion of texture from an in-memory buffer containing pixel data.

The region set can’t be larger than the source data

Parameters

`src_x`	`int`
	Upper left coordinate to use from source data.
`src_y`	`int`
	Upper left coordinate to use from source data.
`dst_x`	`int`
	Upper left destination horizontal coordinate.
`dst_y`	`int`
	Upper left destination vertical coordinate.
`dst_width`	`unsigned int`
	Width of destination region to write. (Must be less than or equal to `width`)
`dst_height`	`unsigned int`
	Height of destination region to write. (Must be less than or equal to `height`)
`width`	`int`
	Width of source data buffer.
`height`	`int`
	Height of source data buffer.
`format`	`CoglPixelFormat`
	The `CoglPixelFormat` used in the source buffer.
`rowstride`	`unsigned int`
	Rowstride of source buffer (computed from width if none specified)
`data`	An array of `uint8_t`
	The actual pixel data.
	The data is owned by the caller of the function.

Return value

Returns:	`gboolean`
	`TRUE` if the subregion upload was successful, and `FALSE` otherwise.
