ImageProcessor::TInputInfo Class Reference

class ImageProcessor::TInputInfo

This class provides functions to read input image details. These details can be used for display in a file browser or to verify the correct capabilities. Prior to use this API, a pointer to ImageProcessor::InputInfoL() interface must be obtained from the active CImgProcessor instance.

BitsPerPixelL()

IMPORT_C TUint32

BitsPerPixelL

(

)

const

Gets the bits per pixel of input image.

DisplayModeL()

IMPORT_C TDisplayMode

DisplayModeL

(

)

const

Gets the display mode of input image.

Extension(TUid)

IMPORT_C TAny *

Extension

(

TUid

aExtension

)

const

Retrieves access to a custom extension.

Parameters

TUid aExtension

The UID of the extension to be retrieved

FormatL(TUid &, TUid &)

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

Gets the input image format

leave: KErrNotReady The effect is not active.

Parameters

TUid & aFormat	Returns the Uid of the format.
TUid & aSubFormat	Returns the sub Uid of the format.

HasAlphaL()

IMPORT_C TBool

HasAlphaL

(

)

const

Gets the the image alpha information.

ImageFrameFormatL()

IMPORT_C TUid

ImageFrameFormatL

(

)

const

(

)

const

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

IsProgressiveL()

IMPORT_C TBool

IsProgressiveL

(

)

const

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

SamplingL()

IMPORT_C TUid

SamplingL

(

)

const

Gets the sampling of input image.

SizeL()

IMPORT_C TSize

SizeL

(

)

const

Gets the size of input image
