Center-aligning text using system.drawing in a given space. 1

[JAG14]

Hi Everyone,

I'm using system.drawing to output an overwritten image to a webpage.
I have a base image, which I then 'draw' the text on to dynamically using values from the DB.

My question is, if I have a space located in the image that is as follows, how do I get the text to center align inside that space?

Base Image 600x80 pixels
Space for text 61x61 pixels starting at top left point x10-y18.

If you need an image example, please ask. This has wasted 3 valuable hours already!

Thanks a million in advance,

Jag14

What methods are you using to write the text out? An example of your code would help.

Hi Mark, Thanks for the response.
I'm using the code specified below (with mods)

<%@ page language="vb" contenttype="image/jpeg" %>  
<%@ import namespace="system.drawing" %>  
<%@ import namespace="system.drawing.imaging" %>  
<%@ import namespace="system.drawing.drawing2d" %>  
<%  
  
response.clear ' make sure Nothing has gone to the client  
  
Dim imgOutput as New System.Drawing.Bitmap(Server.MapPath("headBGVTitle.jpg"))

Dim g as graphics = graphics.fromimage(imgOutput) ' create a New graphic object from the above bmp  

g.smoothingMode = smoothingMode.antiAlias ' antialias objects  
 
' draw the number on the image canvas in verdana 18pt font bold  
g.drawString(iNoOfRooms), New font("verdana",18,fontstyle.bold),systembrushes.windowtext, New pointF(10,18))  
  
 
imgOutput.save(response.outputstream, imageformat.jpeg) ' output to the user  
 
  
' tidy up  
g.dispose()  
imgOutput.dispose()  
response.end  
 
%>

The problem lies in the fact that the 'gDrawstring' Point is only the top left corner of the space available for the text and if 'iNoOfRooms=3' it will produce a misaligned result from 'iNoOfRooms=33'

Thanks again for you help in advance.

In that case, the System.Drawing.StringFormat class may help you.
