Currently I've got the following working just fine without any problems (yet).
header ("Content-type: image/png");
$string = $_REQUEST['text'];
$font = 15;
$width = 300;
$height = 350;
$image = imagecreate($width, $height);
$back = ImageColorAllocate($image, 255, 255, 255);
$border = ImageColorAllocate($image, 0, 0, 0);
ImageFilledRectangle($image, 0, 0, $width, $height, $border);
ImageFilledRectangle($image, 1, 1, $width-2, $height-2, $back);
$text_color = imagecolorallocate($image, 255, 0, 0);
ImageStringWrap($image, $font, 3, 2, $string, $text_color, $width-2 );
imagepng($image);
function ImageStringWrap($image, $font, $x, $y, $text, $color, $maxwidth) {
$fontwidth = ImageFontWidth($font);
$fontheight = ImageFontHeight($font);
if ($maxwidth != NULL) {
$maxcharsperline = floor($maxwidth / $fontwidth);
$text = wordwrap($text, $maxcharsperline, "\n", false);
}
while (list($numl, $line) = each($lines)) {
ImageString($image, $font, $x, $y, $line, $color);
$y += $fontheight;
}
}
While the above works great, one thing I've been failing to work is be able to get line breaks like would come out akin to nl2br()
.
The text that this is pulling from in $_REQUEST['text']
is from the database, which was originally inserted from a textarea and passed to this script via URL. Naturally when people type in a textarea, there are line breaks that come from that. While printing it to the browser via text is easy, I can't seem to get the same result within an image.
I haven't spend a long time working with the GD library, but after searching around I really can't find anything about how to do this. Is it just not possible?
