Ok, preliminary version of the script is available. I can't test it
yet, because I don't have access to any servers with all the required
pieces installed. I should have access to one middle of next week,
so if there's any problems, I should be able to iron them out then.
However, here's a quick rundown of how it works, and what it will do
for you.
The file can be downloaded at:
http://www.softcon.com/php/design.zip
In that file, you'll find two files.
the design_button.html is simply the file you load into the browser.
it will ask for the text you want on the icon.
When you press submit, it will pass the text to a php script called
make_button.php.
This is the piece that does all the work.
I couldn't remember what the required sizes were, so I just put
800x600. You'll need to change these to fit the apple requirements.
I'll of course take care of his when I post the final version, but
for now, those wishing to test it out will need to change these values.
The php code will start with the largest font it can use (33 point)
and decrease the font size down to the largest size that will still
fit into the size requirements of the icon.
After it finds a size that works, it will generate the jpg file, and
dump it to your browser. It does not create a file, or save the info
anywhere, so you'll need to rightclick on the image, and do a save as
to keep the generated file.
Since I'm unable to test this at this time, you may want to have
sighted assistance initially to verify everything worked. You'll
need gd version 1.8 on your webhost for this to work (gd is compiled
into php, so if you're not using the latest versions of all the
available software, it may not work for you)..
That's part of the problem. But, as I said, mid-next week, I should
have it up on a working server, and folks can just use that when they
need a nice graphical icon for their podcasts.
This code is a combination of code from php and mysql 3rd edition,
and the php manual. As mentioned above, it cannot be tested at this
time, but except for the image size, I expect it to work as
advertised. If someone does have all required software versions, and
it still doesn't behave properly, let me know, and I'll patch it to
the best of my ability until I can solve any issues myself upon
obtaining a new server for testing. I've got a Ubuntu box coming,
and I'll be able to solve any outstanding bugs when it arrives.
Any other questions, fel free to inbox me. hope this helps.
Just for reference, the files are pasted below, but you can also
download the pair from the url given above, and that is:
