Pascal

procedure AddMimeType(
    const Ext: string; 
    const MIMEType: string
);

Parameters

Parameters	Description
Ext	File extensions for the MIME type and subtype.
MIMEType	IANA MIME type and subtype for the mapping.

Description

AddMimeType is a procedure that allows adding the new file name extension specified in Ext and the MIME type specified in MIMEType to the mappings in the TIdMimeTable instance. AddMimeType will raise an EIdException exception if the file extension in Ext already exists in the MIME type mapping.

Ext is the case-insensitive file extension including the '.' character. If the period character is not included in Ext, it will be inserted prior to inclusion in the list of file extensions. If Ext is an empty string (''), an EIdException will be raised with the message RSMIMEExtensionEmpty.

MIMEType is the case-insensitive IANA registered MIME type and subtype to be associated with the file extension in Ext. If MIMEType contains an empty string (''), and EIdException will be raised with the message RSMIMEMIMETypeEmpty.

Use GetFileMIMEType to get a MIME type for a specified file name and extension. Use GetDefaultFileExt to find the initial file extension found for a given MIME type and subtype. The MIME type mapping table can be loaded with custom values using LoadFromStrings.
