成员函数文档编制

◆ MAXON_INTERFACE()

MAXON_INTERFACE	(	ImagePixelStorageInterface	,
		MAXON_REFERENCE_COPY_ON_WRITE	,
		"net.maxon.image.interface.imagepixelstorage"
	)

private

◆ Init()

MAXON_METHOD Result <void> Init	(	Int	width ,
		Int	height ,
		const PixelFormat &	format ,
		const Block < Pix > *	defaultColor
	)

Initializes the pixel storage.

参数

[in]	width	Width of the image data.
[in]	height	Height of the image data.
[in]	format	Pixel format of the pixel storage, e.g. ImagePixelStorageClasses::Normal.
[in]	defaultColor	Optional default color to return if no image data is present. Must be in the given PixelFormat. Can be nullptr.

返回: OK on success.

◆ GetWidth()

MAXON_METHOD Int GetWidth

(

)

const

Returns the width of the pixel storage.

◆ GetHeight()

MAXON_METHOD Int GetHeight

(

)

const

Returns the height of the pixel storage.

◆ GetChannelCount()

MAXON_METHOD Int GetChannelCount

(

)

const

Returns the total number of channels of the pixel storage.

◆ GetPixelFormat()

MAXON_METHOD PixelFormat GetPixelFormat

(

)

const

Returns the pixel format connected to this pixel storage.

◆ GetPixelHandler()

MAXON_METHOD Result < GetPixelHandlerStruct > GetPixelHandler	(	const PixelFormat &	dstFormat ,
		const ChannelOffsets &	channelOffsets ,
		const ColorProfile &	srcColorProfile ,
		const ColorProfile &	dstColorProfile ,
		GETPIXELHANDLERFLAGS	flags
	)		const

To access pixel data a GetPixelHandlerStruct is needed. This optimizes the access to the pixel data see GetPixelHandlerStruct .

参数

[in]	dstFormat	Destination pixel format that should be read with this pixel handler.
[in]	channelOffsets	Destination channel offset in bits.
[in]	srcColorProfile	Optional parameter which is only necessary if the color spaces of the given pixel formats doesn't match. In that case the conversion will be performed using the correct color conversion.
[in]	dstColorProfile	Optional parameter which is only necessary if the color spaces of the given pixel formats doesn't match. In that case the conversion will be performed using the correct color conversion.
[in]	flags	Flags for the GetPixel operation.

返回: A valid GetPixelHandlerStruct struct if successful.

◆ SetPixelHandler()

MAXON_METHOD Result < SetPixelHandlerStruct > SetPixelHandler	(	const PixelFormat &	srcFormat ,
		const ChannelOffsets &	channelOffsets ,
		const ColorProfile &	srcColorProfile ,
		const ColorProfile &	dstColorProfile ,
		SETPIXELHANDLERFLAGS	flags ,
		const Delegate < void(const UpdateRegion &)> &	updateRegionNotification
	)

To access pixel data a SetPixelHandlerStruct is needed. This optimizes the access to the pixel data see SetPixelHandlerStruct .

参数

[in]	srcFormat	Source pixel format that should be written with this pixel handler.
[in]	channelOffsets	Source channel offsets in bits.
[in]	srcColorProfile	Optional parameter which is only necessary if the color spaces of the given pixel formats doesn't match. In that case the conversion will be performed using the correct color conversion.
[in]	dstColorProfile	Optional parameter which is only necessary if the color spaces of the given pixel formats doesn't match. In that case the conversion will be performed using the correct color conversion.
[in]	flags	Flags for the SetPixel operation.

返回: A valid SetPixelHandlerStruct struct if successful.

◆ GetComponent()

MAXON_METHOD Result <void> GetComponent	(	Int	component ,
		const ImagePos &	pos ,
		Pix *	data ,
		Int	inc ,
		GETPIXELFLAGS	flags
	)		const

Access single components of the image.

参数

[in]	component	Index of the component.
[in]	pos	ImagePos of the data to read.
[in]	data	Destination buffer.
[in]	inc	Distance between 2 pixels in the destination buffer.
[in]	flags	Flags to control the read operation.

返回: OK on success.

◆ SetComponent()

MAXON_METHOD Result <void> SetComponent	(	Int	component ,
		const ImagePos &	pos ,
		const Pix *	data ,
		Int	inc ,
		SETPIXELFLAGS	flags
	)

Access single components of the image.

参数

[in]	component	Index of the component.
[in]	pos	ImagePos of the data to write.
[in]	data	Source buffer.
[in]	inc	Distance between 2 pixels in the source buffer.
[in]	flags	Flags to control the write operation.

返回: OK on success.
