Detailed Description

Represents an image type, including pixel format and image dimensions.

Using a partially-specified image type is allowed when defining the buffer format of a sink. The sink will fill the other fields with data from the device automatically.

Constructor & Destructor Documentation

ImageType() [1/2]

ImageType ( PixelFormat  pixel_format )

inlinenoexcept

Constructs an image type, specifying only a pixel format.

Width and height remain unspecified.

Parameters

[in]

pixel_format

The pixel format of the image

ImageType() [2/2]

ImageType ( PixelFormat  pixel_format, uint32_t  width, uint32_t  height  )

inlinenoexcept

Constructs an image type, specifying pixel format, width and height.

Parameters

[in]	pixel_format	The pixel format of the image
[in]	width	The width of the image in pixels
[in]	height	The height of the image in pixels

Member Function Documentation

height()

uint32_t height ( ) const

inlinenoexcept

Returns the height of this image type.

Returns

The height of this image type, or 0 if the height is not specified.

operator!=()

bool operator!= ( const ImageType &  op2 ) const

inlinenoexcept

Checks whether two image types are not equal.

Parameters

op2	Other image type

Returns

true if this image type is different from op2, otherwise false.

operator==()

bool operator== ( const ImageType &  op2 ) const

inlinenoexcept

Checks whether two image types are equal.

Parameters

op2	Other image type

Returns

true if this image type is equal to op2, otherwise false.

pixel_format()

PixelFormat pixel_format ( ) const

inlinenoexcept

Returns the pixel format of this image type.

Returns

The pixel format of this image type, or PixelFormat::Unspecified if the pixel format is not specified.

width()

uint32_t width ( ) const

inlinenoexcept

Returns the width of this image type.

Returns

The width of this image type, or 0 if the height is not specified.
