Client applications send text and image data to the Server Option in a writetext stream. To process writetext stream data, a Server Option application cannot employ functions normally used to process parameter data. Instead, a Server Option application must use special text and image functions.
A Server Option application can send text or image data to a client application in either of the following ways:
data stream – If the row of returned data contains one column of text or image data, the row may be sent as a data stream. The length of the data is between 0 and 2 gigabytes.
describe/send row – If the row of returned data contains columns in addition to a text or image column, the text or image data may be sent using the describe/send row method. The length of the data cannot exceed 32KB.
The following subsections describe text and image issues for the Server Option:
