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.
