OpenBufferedFileImageL(RFs &, const TDesC8 &)
Create new image instance from buffered image data. Method leaves with appropriate error code if buffer data could not be used. If buffer contains multi-image, created image instance contains handle to the first image.
- Since
- 3.0
Parameters
| RFs & aFs | Fileserver reference. |
| const TDesC8 & aDataBuf | Buffer reference. |
OpenBufferedFileImageL(RFs &, const TDesC8 &, TInt)
Create new image instance from buffered image data. Method leaves with appropriate error code if buffer data could not be used or image index is out of bounds. If buffer contains multi-image, created image instance contains handle to the first image.
- Since
- 3.0
Parameters
| RFs & aFs | Fileserver reference. |
| const TDesC8 & aDataBuf | Buffer reference. |
| TInt aImageIndex | Image index. This is used in multi-image file to determine which image is opened. |
OpenBufferedFileImageL(RFs &, const TDesC8 &, TInt, const TUint32)
Create new image instance from buffered image data. Method leaves with appropriate error code if buffer data could not be used or image index is out of bounds. If buffer contains multi-image, created image instance contains handle to the first image.
- Since
- 3.0
Parameters
| RFs & aFs | Fileserver reference. |
| const TDesC8 & aDataBuf | Buffer reference. |
| TInt aImageIndex | Image index. This is used in multi-image file to determine which image is opened. |
| const TUint32 aOptions | Special opening options. Refer to MIHLFileImage header. |
OpenFileImageL(RFs &, const TDesC &)
Open file and create new image instance. Default filemode is EFileShareReadersOnly and if opening fails, EFileShareAny is used. Method leaves with appropriate error code if file could not be opened. If file is multi-image, new image contains handle to the first image.
Note! Method may leave with KErrBadHandle if RFs::ShareProtected() method is not called!
Parameters
| RFs & aFs | Fileserver reference. |
| const TDesC & aFilename | Full path of image file. |
OpenFileImageL(RFs &, const TDesC &, TInt)
Open file and create new image instance. Default filemode is EFileShareReadersOnly and if opening fails, EFileShareAny is used. Method leaves with appropriate error code if file could not be opened or index is out of bounds.
Note! Method may leave with KErrBadHandle if RFs::ShareProtected() method is not called!
Parameters
| RFs & aFs | Fileserver reference. |
| const TDesC & aFilename | Full path of image file. |
| TInt aImageIndex | Image index. This is used in multi-image file to determine which image is opened. |
OpenFileImageL(RFs &, const TDesC &, TInt, const TUint32)
Open file and create new image instance. Default filemode is EFileShareReadersOnly and if opening fails, EFileShareAny is used. Method leaves with appropriate error code if file could not be opened or index is out of bounds.
Note! Method may leave with KErrBadHandle if RFs::ShareProtected() method is not called!
Parameters
| RFs & aFs | Fileserver reference. |
| const TDesC & aFilename | Full path of image file. |
| TInt aImageIndex | Image index. This is used in multi-image file to determine which image is opened. |
| const TUint32 aOptions | Special opening options. Refer to MIHLFileImage header. |
OpenFileImageL(RFile &)
