TCPSendPicture Method 380

Applies To: TCPSocket

Description

This method is used to transmit a picture represented by a Bitmap object to a TCP/IP socket. The picture may be transmitted in GIF or in PNG format.

The argument to TCPSendPicture is a 1 or 2-element array as follows:

[1]	Bitmap name	character vector
[2]	Picture format	character vector, 'GIF' or 'PNG'

If Picture format is omitted, the default is GIF format.

Note that the Style of the TCPSocket object must be set to 'Raw' before you execute the TCPSendPicture method.

The (shy) result of the method is an integer that reports the number of bytes that were transmitted.

Example

      S1.TCPSendPicture 'BM' 'PNG'        
4930

Note

Although PNG is recognised as the latest graphics standard for displaying pictures, not all Web browsers support it.
