Constructor for this class.

Destructor for this class.

Closes the file. If using a local file session, it closes it. Calls ECom to tell it the encoder instance is no longer required.

Frees all other resources owned by the object prior to its destruction.

Asynchronously cancels any conversions currently in progress.

Encodes a bitmap asynchronously.

When encoding is complete, successfully or otherwise, the status is returned in aRequestStatus.

TBmpImageData

Sets up background convert cycle, bypassing Convert().

Use this function to inititate CImageEncoderPlugin::InitCustomAsyncL(aParam), which if successful will start background processing. Convert() uses the same mechanism as CustomAsync(), and therefore cannot be used concurrently. Cancel() and other related functions still work as expected.

Note: For use by plugin writers only.

Calls CImageEncoderPlugin::HandleCustomSyncL() that executes user defined plugin specific functions. Subsequent behaviour therefore depends on the CImageEncoderPlugin class.

Note: For use by plugin writers only.

Creates a plugin encoder for a specified MIME type and writes output to a descriptor.

The client supplies a MIME type which will be used to try and select an appropriate plugin encoder. If an appropriate encoder is found, it creates it.

TOptions

Creates a plugin encoder based on optional parameters and writes output to a descriptor.

The client must supply a basic image type (and a sub-type, if applicable) or specific encoder/class, implementation UID which will be used to try and select an appropriate plugin encoder. If an appropriate encoder is found, it is created.

Note: Every image format has two IDs, known as the type and the sub-type (although generally the sub-type is KNullUid). To retrieve a list of supported types and sub-types that can be encoded, use the static functions GetImageTypesL() and GetImageSubTypesL().

If no plugin encoder can be found that matches the details provided in aImageType, aImageSubType and possibly aEncoderUid this function leaves with KErrNotFound or KEComErrNoInterfaceIdentified.

Creates an encoder based on a specified MIME type and write output to a named file.

The client supplies a MIME type which will be used to try and select an appropriate plugin encoder. If an appropriate encoder is found, it is created.

If any file related errors are encountered opening the specified file, this function leaves with an appropriate file related leave code.

TOptions

Creates an encoder based on a supplied parameters and writes output to a named file.

The client must supply a basic image type (and a sub-type, if applicable) or a specific encoder implementation UID, which will be used to try and select an appropriate plugin encoder. If an appropriate encoder is found, it is created.

Note: Every image format has two IDs, known as the type and the sub-type (although generally the sub-type is KNullUid). To retrieve a list of supported types and sub-types that can be encoded, use the static functions GetImageTypesL() and GetImageSubTypesL().

If no plugin encoder can be found that matches the details provided in aImageType, aImageSubType and possibly aEncoderUid this function leaves with KErrNotFound or KEComErrNoInterfaceIdentified.

If any file related errors are encountered opening the specified file, this function leaves with an appropriate file related leave code.

Creates an encoder based on a specified MIME type and write output to a named file.

Get a list of the file extensions that can be encoded and their corresponding MIME types, based on the currently available encoder plugins.

Ownership of the array is passed to the caller, so before the array goes out of scope in the client, the caller must call the array's ResetAndDestroy() method to free any entries.

For a given basic image type, returns a list of the image sub-types that can be encoded, based on the currently available encoder plugins.

Each entry in the returned array consists of the "display string" for the plugin as well as the UID for the sub-type. The first UID represents the basic type and is always set to aImageType.

Ownership of the array is passed to the caller, so before the array goes out of scope in the client, the caller must call the array's ResetAndDestroy() method to free any entries.

Returns a list of the basic image types that can be encoded, based on the currently available encoder plugins.

The returned array contains entries for the supported image types. Each entry consists of the "display string" as well as the UID for that image type. Since this function only returns basic image type UID's, the second UID which represents the sub-type will always be zero.

Ownership of the array is passed to the caller so, before the array goes out of scope in the client, the caller must call the array's ResetAndDestroy() method to free any entries.

Gets a list of encoder implementations UIDs that have some specific uids (properties, image type, image sub-type or class uids).

Gets a list of encoder implementations UIDs that have some specific required uids (properties, image type, image sub-type or class uids).

Gets a list of the properties of a specific encoder plugin.

Create a list of encoders that support the specified image type.

KUidICLJpegEXIFInterface KUidICLJpegImageFrameInterface

Returns the implementation UID of the encoder being used to encode the bitmap.

Creates a list of encoders that support the specified MIME type.

Create an encode construct using a image type, sub type and encoder implementation UID.

Called internally to create a CImageEncoder and associated iRelay body

Actual factory function for CImageEncoder - ie. it creates the object Called back plugin - to allow plugin to override if required

Returns the associated CImageEncoderPlugin.

This is part of support for extended codecs, for use within classes derived from CImageEncoder. Allows the extended CImageEncoder object to talk to its CImageEncoderPlugin equivalent.

Note: For use by plugin writers only.

Optional call from client which may be made on the encoder to allow analysis of image prior to calling Convert.

Should be called once encode is fully set up e.g. any encode operations defined.

Flags to control how the image is encoded. These can be combined using an OR operation.
