Introduction

To fit WAP images to different devices, I have made a WbmpServer to:

read a gif or jpg image from the net,
determine the target device
and present a WBMP suitable for the device.

If your WAP screen is small, the image is small. If the screen is large, the image can be as large as you want it.

The service is 100% free
This is a test service, no guarantee for stability or correctness

For the time being, the service is adapted to the following devices, or User-Agent s:

WinWAP
EricssonR320
Nokia7110
Nokia9110
AUR PALM WAPPER
UPG1
Mozilla/4.72

If you use another device, or feel that your device is improperly supported, please contact me.

Usage

We start with the image that is (or was) at:

http://www.cs.ubc.ca/spider/phillips/spock.gif

The simplest way to present a WAP version of this image, is the following WML code:

<img src="http://rhj.dyndns.info:3333/test.wbmp?adr=www.cs.ubc.ca/spider/phillips/spock.gif" alt="Loading image ..."/>

Depending on the size of your WAP device, the image might be presented like this:

The server will accept various arguments. The syntax :

arg=verdi+arg=verdi+...

In addition to adr, the following arguments may be used:

Argument Description Value Default Sample

frame Place a frame around the image false/true false

logo present image as logo false/true false

random An alternative rastering technique false/true false

faktor Changing the aspect ratio.
May be needed because some
devices have non-square
pixels.
float 1.0 2.0

0.5:

mx & my Maximum width and height of image float & float No default. The server will
try to adapt the image with
maximum possible size for
the device. These
arguments may
cause smaller images than
the device screen,
but never larger. 25 & 25:

Sample Code

If no arguments are given, the server will generate a wml file. This is the code given by a call on: http://rhj.dyndns.info:3333/: The result of http://rhj.dyndns.info:3333/ in WinWAP 2.2:
