i'm using GD library 2.0.34 with php 5.2.6 to create image with text. when i use imagettftext function to apply ttf file, then GD generates blank image. but same code is working fine with imagestring function. Please can somebody tell me where is problem. here is code
$len = strlen($str);
$font = "fonts/".$fontFile;
// draw each character individually
for ($i = 0; $i < $len; $i++)
{
// calculate angle along arc
$a = ($aStart * ($len - 1 - $i) + $aEnd * $i) / ($len - 1);
// draw individual character
imagefilledrectangle($imgChar, 0, 0, $xFont, $yFont,$transparent2);
imagettftext($imgChar, $nFont, 0, 0, 0, $textColor, $font,$str[$i]); // not working
// imagestring($imgChar, $nFont, 0, 0, $str[$i], $textColor); //working fine
// rotate character
$imgTemp = imagerotate($imgChar, (int)$a + 90 * ($bCCW ? 1 : -1), $transparent2);
$xTemp = imagesx($imgTemp);
$yTemp = imagesy($imgTemp);
// copy to main image
imagecopy($img, $imgTemp,
$iCentre + $iRadius * cos(deg2rad($a)) - ($xTemp / 2),
$iCentre - $iRadius * sin(deg2rad($a)) - ($yTemp / 2),
0, 0, $xTemp, $yTemp);
}
return $img;
