I am looking for a person who is skilled with the PHP GD lib.

Basicaly what I want is for this person to be able to work as part of a small team developing a fantasy (humans, orcs etc) style online strategy game.

The main things that they would be required to do is develop a 'map' system to allow visual navigation of the online 'world'.

I would do this myself, but I have only ever experimented with GD, and as such, I have little skill with it.

I don't know anyone on here who's ever used PHP for graphics, certainly not me. SI is the main graphics person but he's into C++ and 3D so not really what you're looking for

Neither do I, which is why I asked heh.

Using php to generate images is a world away from what SI is doing, but it is something I am looking into atm for some other work I'm, doing.

Paste more information here and I'll see if I want to help you

Basicaly, what I want to be done is this:

Script takes data from the DB (land type, armies on the land, fortifications etc), checks to see if they exist on each bit of land.

If it does, make a small modification to the lands default image (like a little icon in the top left for an army, top right for fortifications etc). This is then output as a sort of 'map' which can be 'scrolled' across. I have allready made this system, its just a case of getting someone who can do the image manipulation.

i've used php for image manipulation, not used the PHP GD lib though. i could probably do what you're asking. i just don't have the timem, sorry.

I've done this sort of thing before, I just found it to be an amazingly large performance hit

If you come find me on IRC (not tonight, and prolly not tomorrow ngiht) I can give you a hand.

Pay me, and I will do it all for you \o/

Oooh, pay :/

It's really not that hard to learn. Read the manual. Read other people's scripts. I was doing custom stuff within 30 minutes when I first read the manual.

This is the basic of what you need, unfortunatly I cant dedicate the time to getting involved in a project.

Code:

<?php

/*
image_test.php
icon placement script
27th Dec 2002
*/

Header("Content-type: image/jpeg");

$image = ImageCreateFromJPEG("background.jpg");
$icon  = ImageCreateFromJPEG("icon1.jpg");
$trans = ImageColorAt($icon, 0, 0);
ImageColorTransparent($icon, $trans);
$width = ImageSX($icon);
$height = ImageSY($icon);
ImageCopyResized($image, $icon, 100, 100, 0, 0, $width, $height, $width, $height);
ImageJPEG($image);
ImageDestroy($image);

?>

This code will take 2 images (background.jpg & icon1.jpg) it will then get the pixel colour from postion 0,0 in icon1.jpg and make that the transparent color for the child image to be generated. icon1.jpg is then superimposed onto background and the resulting image is displayed (this image is then destroyed, or your server will run out of memory very quickly) - You could easily recur through this to add other icons etc.

Although I have used jpg's here you are probably better using the PNG filetype as GD can handle transparency and colour manipulation better with PNG
