Since: 3.0

Parameters

const TDesC & aUri
const TDesC & aShow

NewFetchImageData(const TDesC &)

TInt

NewFetchImageData

(

const TDesC &

aUri

)

[pure virtual]

This method is called to retrieve the absolute path of an image given the uri. The SVGT control requests the absolute path to provide the client with control of the location of the images. This function should be an asynchronous, i.e. it should not block. On completion of fetching of the file, it should notify the control using AssignImageData() function
