IMPORT_C void

ConstructL

(

)

[protected]

Second phase constructor.

Obtains the reduced size of the decoded bitmap based on the input parameters and updates aReducedSize with this value.

Parameters
aOriginalSize	A reference to the original size of an image.
aScalingCoeff	The scaling coefficient to be applied.
aReducedSize	A reference to the new size of an image.

Return Value: KErrNone If the function call was successful. A range of system wide error values.

Obtains the scaling coefficient

Parameters
aOriginalSize	A reference to the original size of an image.
aDesiredSize	A reference to the desired size of an image.

Return Value: The scaling coefficient, for example: Original size = 1 or -1, Half original size = -2, Quarter original size = -3 etc.
