Encoding Information in Clustered-Dot Halftones

Abstract: While barcodes are a popular means for encoding information for printed matter, they add unsightly overt content. If an image is already part of the composition of a printed label or page, hiding information in that image is an attractive alternative to barcodes. This paper offers a new method for e ...

curlopt_transfer_encoding

CURLOPT_TRANSFER_ENCODING(3)				     curl_easy_setopt options				      CURLOPT_TRANSFER_ENCODING(3)

NAME

       CURLOPT_TRANSFER_ENCODING - ask for HTTP Transfer Encoding

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TRANSFER_ENCODING, long enable);

DESCRIPTION

       Pass a long set to 1 to enable or 0 to disable.

       Adds  a	request  for compressed Transfer Encoding in the outgoing HTTP request. If the server supports this and so desires, it can respond
       with the HTTP response sent using a compressed Transfer-Encoding that will be automatically uncompressed by libcurl on reception.

       Transfer-Encoding differs slightly from the Content-Encoding you ask for with CURLOPT_ACCEPT_ENCODING(3) in  that  a  Transfer-Encoding	is
       strictly  meant to be for the transfer and thus MUST be decoded before the data arrives in the client. Traditionally, Transfer-Encoding has
       been much less used and supported by both HTTP clients and HTTP servers.

DEFAULT

       0

PROTOCOLS

       HTTP

EXAMPLE

       TODO

AVAILABILITY

       Added in 7.21.6

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
