I'm implementing the createimagemap.php DevGuide sample in C#. When I use
"GIF" as the format argument to RenderMap I see a blank image with a brown
background (which is the color argument). When I use PNG or JPG I just see a
blank image.
Here's my C# code.
MgByteReader byteReader = renderingService.RenderMap(map, selection,
envelope, width, height, color, "PNG");
Response.AddHeader("Content-type: ", byteReader.GetMimeType() );
byte[] buffer= new byte[50000];
while (byteReader.Read(buffer, 50000) != 0)
{
Response.BinaryWrite(buffer);
}
Any suggestions? I've also tried Response.Buffer and Response.BufferOutput
to no effect.
Thanks.
