drawing on images with php

rapaddict_dot_com · Post by **rapaddict_dot_com** » Fri Jul 02, 2004 2:40 am

I have a site where I want people to be able to make personal banners for there homepage

I want it to have 2 variables for the text

$text-name
and $text-desc

so it has the pre-selected banner and it adds text-name in big letters with customizable colors/fonts and the desc smaller

is there a way to do this?

also i want it to save as $sess_user."_banner.jpeg"

and if that file already exists then I want it to delete it

does anyone know how to do all this?

^I got that code from a website.

How do I make it so the person can edit which font is being used? and so the colors on the form are RED GREEN BLUE instead of the hex codes.

Well.. it looks like the RGB values are already 0-255 fields... Next thing, that script was written with register_globals on.. for fonts, you'll have to enumerate the fonts you have available for them to use.

and in english...?

hehe im a bit of a notice with the drawing thing...

is there an example I can see with a text-chooser?

hmm.. you could search a certain folder for truetype fonts or whatever your version of FreeType supports... You could provide a simple list of them, or create an image based on each.. anything's fairly possible..

RED in a form's drop down menu can be: 255-0-0
GREEN in a form's drop down menu can be: 0-255-0
BLUE in a form's drop down menu can be: 0-0-255

eg.

Code: Select all

&lt;option value="255-0-0"&gt;Red Font&lt;/option&gt;

Then on the form handling page, [php_man]explode[/php_man]() by "-" and you have an array of the hex values.

eg.

Code: Select all

<?php
$hex = explode ("-", $color);
?>
