Member Function Documentation

BitsPerPixelL ( )

IMPORT_C TUint32

BitsPerPixelL

(

)

const

Gets the bits per pixel of input image.

Return Value: bits per pixel of image.

DisplayModeL ( )

IMPORT_C TDisplayMode

DisplayModeL

(

)

const

Gets the display mode of input image.

Return Value: display mode of image.

Extension ( TUid )

IMPORT_C TAny *

Extension

(

TUid

aExtension

)

const

Retrieves access to a custom extension.

Parameters
aExtension	The UID of the extension to be retrieved

Return Value: Extension corresponding to the UID given as a parameter.

FormatL ( TUid &, TUid & )

IMPORT_C void	FormatL	(	TUid &	aFormat,
			TUid &	aSubFormat
		)	const

Gets the input image format

Parameters
aFormat	Returns the Uid of the format.
aSubFormat	Returns the sub Uid of the format.

Leave Codes
KErrNotReady	The effect is not active.

HasAlphaL ( )

IMPORT_C TBool

HasAlphaL

(

)

const

Gets the the image alpha information.

Return Value: true if input image has alpha channel.

ImageFrameFormatL ( )

IMPORT_C TUid

ImageFrameFormatL

(

)

const

Gets the uid of frame format of input image. When calling TInputInfo::DisplayModeL() returns ENone, this ImageFrameFormatL() could be used to get image frame format.

Return Value: uid of frame format of the image.

IsInterlacedL ( )

IMPORT_C TBool

IsInterlacedL

(

)

const

Gets the source image information and scans whether the source image is interlaced or not.

Return Value: ETrue if the source image is interlaced otherwise EFlase.

IsProgressiveL ( )

IMPORT_C TBool

IsProgressiveL

(

)

const

Gets the source image information and scans whether the source image allows progressive decoding or not.

Return Value: ETrue if the source image allows progressive decoding otherwise EFalse.

SamplingL ( )

IMPORT_C TUid

SamplingL

(

)

const

Gets the sampling of input image.

Return Value: sampling of image.

SizeL ( )

IMPORT_C TSize

SizeL

(

)

const

Gets the size of input image

Return Value: size of the image
