Detailed Description

A primitive describing a volume (3D), image (2D) or line (1D) of pixels in memory.

In case of a rectangle, depth must be 1. Pixels are stored as a succession of "depth" slices, each containing "height" rows of "width" pixels.

Ogre::PixelBox::PixelBox	(	const Box &	extents,
		PixelFormat	pixelFormat,
		void *	pixelData = `0`
	)

inline

Constructor providing extents in the form of a Box object.

This constructor assumes the pixel data is laid out consecutively in memory. (this means row after row, slice after slice, with no space in between)

Parameters

extents	Extents of the region defined by data
pixelFormat	Format of this buffer
pixelData	Pointer to the actual data

Definition at line 316 of file OgrePixelFormat.h.

Ogre::PixelBox::PixelBox	(	uint32	width,
		uint32	height,
		uint32	depth,
		PixelFormat	pixelFormat,
		void *	pixelData = `0`
	)

inline

Constructor providing width, height and depth.

This constructor assumes the pixel data is laid out consecutively in memory. (this means row after row, slice after slice, with no space in between)

Parameters

width	Width of the region
height	Height of the region
depth	Depth of the region
pixelFormat	Format of this buffer
pixelData	Pointer to the actual data

PixelBox Ogre::PixelBox::getSubVolume ( const Box & def ) const

Return a subvolume of this PixelBox.

Parameters

def	Defines the bounds of the subregion to return

Returns: A pixel box describing the region and the data in it

Remarks: This function does not copy any data, it just returns a PixelBox object with a data pointer pointing somewhere inside the data of object.

Exceptions

Exception(ERR_INVALIDPARAMS) if def is not fully contained

void* Ogre::PixelBox::getTopLeftFrontPixelPtr ( ) const

Return a data pointer pointing to top left front pixel of the pixel box.

Remarks: Non consecutive pixel boxes are supported.
