int vil1_image_proxy_impl::components ( ) const [inline, virtual]

Dimensions: Planes x W x H x Components.

Implements vil1_image_impl.

Definition at line 44 of file vil1_image_proxy.cxx.

int vil1_image_proxy_impl::bits_per_component ( ) const [inline, virtual]

Number of bits per component.

Size (in bits) for the smallest entity of the image.

Implements vil1_image_impl.

Definition at line 45 of file vil1_image_proxy.cxx.

enum vil1_component_format vil1_image_proxy_impl::component_format ( ) const [inline, virtual]

Format.

A standard RGB RGB RGB image has

components() == 3
bits_per_component() == 8
component_format() == VIL1_COMPONENT_FORMAT_UNSIGNED_INT Use vil1_print(fmt) to return a string description of the format fmt.

Implements vil1_image_impl.

Definition at line 46 of file vil1_image_proxy.cxx.

char const* vil1_image_proxy_impl::file_format ( ) const [inline, virtual]

Return a string describing the file format.

Only file images have a format, others return 0

Reimplemented from vil1_image_impl.

vil1_image vil1_image_proxy_impl::get_plane ( unsigned int p ) const [inline, virtual]

return the ith plane.

Reimplemented from vil1_image_impl.

Definition at line 50 of file vil1_image_proxy.cxx.

bool vil1_image_proxy_impl::get_section	(	void *	buf,
		int	x0,
		int	y0,
		int	width,
		int	height
	)			const `[inline, virtual]`

Copy buffer of this to BUF.

The buffer is stored like this for each pixel: component0(plane0,plane1,plane2,...),component1(plane0,plane1,plane2,...),...
total size of BUF in bytes should be (bits_per_component * components + 7) / 8 i.e. rounding to the next multiple of 8 bits (only correct if 1 byte = 8 bits)

Implements vil1_image_impl.

bool vil1_image_proxy_impl::put_section	(	void const *	buf,
		int	x0,
		int	y0,
		int	width,
		int	height
	)			`[inline, virtual]`

Copy plane PLANE of BUF to this.

The buffer should look like this for each pixel: component0(plane0,plane1,plane2,...),component1(plane0,plane1,plane2,...),...
total size of BUF in bytes should be (bits_per_component * components + 7) / 8 i.e. rounding to the next multiple of 8 bits (only correct if 1 byte = 8 bits)
