Hi

 

has anyone successfully wrapped text in a image generated on the fly?  If so can you let me know how.  Thanks

Have you read the User Comments posted at the bottom of the php.net imagestring page? There are a number of examples for wrapping text.

Ok so now i have this

 

<?
$title="this is my wrapped text, yes my wrapped text and i really neeeeeeeeeeeeeed to wrap the text text text";
$imgfile= 'blank.png';
$outfile=@ImageCreateFromPNG($imgfile);
$red=imagecolorallocate($outfile,255,0,0);
$grey=imagecolorallocate($outfile,128,128,128);

$font1='arial.ttf';
$maxwidth=363;

function ImageStringWrap($imgfile, $font1, $x, $y, $title, $red, $maxwidth)
{
    $fontwidth = ImageFontWidth($font1);
    $fontheight = ImageFontHeight($font1);

    if ($maxwidth != NULL) {
        $maxcharsperline = floor($maxwidth / $fontwidth);
        $text = wordwrap($text, $maxcharsperline, "\n", 1);
      }

    $lines = explode("\n", $title);
    while (list($numl, $line) = each($lines)) {
        ImageString($imgfile, $font1, $x, $y, $line, $red);
        $y += $fontheight;
      }
}

ImageStringWrap($imgfile, $font1, 0, $y, $title, $red, ImageSX($imgfile) );




imagepng ($outfile);
imagedestroy($outfile);

?>

 

But I get these error messages...any ideas?

imagesx will only work with one of the GD image creation functions.

 

Here - try this....you'll have to work with it to make it pretty.

 

<?php

header ("Content-type: image/png");

$string = "this is my wrapped text, yes my wrapped text and i really neeeeeeeeeeeeeed to wrap the text text text" ;
$font = "Arial.ttf";

$width = 300;
$height = 100;
$image = imagecreate ($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", 1);
}

$lines = explode("\n", $text);
while (list($numl, $line) = each($lines)) {
ImageString($image, $font, $x, $y, $line, $color);
$y += $fontheight;
}
}
