CATable::GraphToStream

<< Back to CATable

bool GraphToStream(stream, mimeType)

Description

Creates a graph image of the data contained in the CATable object formatted using the mimeType, and writes it to stream, a Windows IStream. The size of the image in pixels is controlled by the GraphWidth and GraphHeight properties of the table.

Note: Note: An IStream is not interchangeable with a .NET System.Io.Stream object (including a Response.OutputStream object in ASP.NET). A wrapper class is necessary for converting between these. TBD: The Wrapper class and more instructions should be included here.

Return value

Boolean (success)

Parameters

• stream – string
• mimeType – string, usually one of:
  • "image/png"
  • "image/jpeg"
  • "image/bmp"
  • "image/tiff"

Usage

tab.GraphWidth = 350
tab.GraphHeight = 200
dim outStream as StringConnector = _new StreamConnector(Response.OutputStream)
b = tab.GraphToStream( outStream, "image/jpeg")
