Parameter

Description

nIndex

Zero-based index of the commercial frame. The total number of commercial frames available inside the ID3V2 tag can be obtained through a call to the TagsEditor.ID3V2_FrameCountGet method with the strFrameId parameter set to "COMR".

strPathname

String representing the absolute pathname of the output graphic file.

nFormat

Graphic format of the output graphic file.

Supported values are the following:

Mnemonic value	Value	Meaning
GRAPHIC_FORMAT_ORIGINAL	-1	Original format used to store the picture inside the tag. When this option is selected, the output graphic file will be an exact copy of the contents of the picture frame. You can determine the original graphic format, through its MIME type, by calling the TagsEditor.ID3V2_PictureFrameInfoGet method with the parameter nInfo set to ID3V2_FRAME_INFO_MIME_TYPE; this information can be also useful to determine the file extension to use when composing the strPathname parameter above.
GRAPHIC_FORMAT_BMP	0	The output file will be converted to BMP format
GRAPHIC_FORMAT_JPEG	1	The output file will be converted to JPEG format
GRAPHIC_FORMAT_PNG	2	The output file will be converted to PNG format
GRAPHIC_FORMAT_GIF	3	The output file will be converted to GIF format
GRAPHIC_FORMAT_TIFF	4	The output file will be converted to TIFF format

nFormatParameter

Eventual parameter required by the chosen graphic format.

When the nFormat parameter is set to GRAPHIC_FORMAT_JPEG, this parameter defines the JPEG compression factor whose range can be in the range from 0 (Maximum compression, Lower Quality) to 100 (Minimum compression, Higher Quality).

Return value

Value	Meaning

Negative value	An error occurred (see the LastError property for further error details)
enumErrorCodes.ERR_NOERROR (0)	The method call was successful.
