I just read a wicked tutorial on DiscoMoose on how to add text onto an existing png file and now I’m ready to make my next widget! it’s going to be a custom link box with a variety of button styles to choose from. Choose any text and the button will be displayed with the text on there.
It might save a lot of trouble for newbies who don’t have experience in coding or if someones best image app is MSPaint!
here’s my first test to see if I could run the code..
it is called with http://www.fiddyp.co.uk/internal/testingphp/png.php?text=woot!
here is the code for png.php
[php]
// load the image from the file specified:
$im = imagecreatefrompng(“button.png”);
// if there’s an error, stop processing the page:
if(!$im)
{
die(“”);
}
// define some colours to use with the image
$yellow = imagecolorallocate($im, 255, 255, 0);
$black = imagecolorallocate($im, 0, 0, 0);
// get the width and the height of the image
$width = imagesx($im);
$height = imagesy($im);
// draw a black rectangle across the bottom, say, 20 pixels of the image:
//imagefilledrectangle($im, 0, ($height-20) , $width, $height, $black);
// now we want to write in the centre of the rectangle:
$font = 4; // store the int ID of the system font we’re using in $font
$text = $_GET['text']; // store the text we’re going to write in $text
// calculate the left position of the text:
$leftTextPos = ( $width – imagefontwidth($font)*strlen($text) )/2;
// finally, write the string:
imagestring($im,$font,$leftTextPos-1, $height-35,$text,$black);
imagestring($im, $font, $leftTextPos, $height-36, $text, $yellow);
// output the image
// tell the browser what we’re sending it
Header(‘Content-type: image/png’);
// output the image as a png
imagepng($im);
// tidy up
imagedestroy($im);
[/php]
yey!
I had some fun today programming a bot, or, I like to call it a dog. More accurately a MyBlogLogDogg.
phew! I just made 2 new widgets to show the UK and Euromillions Lottery results, it took all of 20 minutes! hehe, these widgets are getting easier and easier to make!
