Set the raw bytes of an embedded file attachment

Replaces the attachment's embedded file data with the given raw bytes. Wraps FPDFAttachment_SetFile. The attachment's CreationDate and checksum dictionary entries are automatically updated; all other entries of the embedded file stream and its /Params dictionary (including the MIME Subtype and anything set with pdf_attachment_set_dict_value()) are cleared by PDFium during the write — set those entries after this call. The description set with pdf_attachment_set_description() lives on the file specification and is kept.

Usage

pdf_attachment_set_data(att, data)

Arguments

data
