Problems are only with the angle and positioning ( because i must rotate the whole image then write a text and rotae it back ).

Wow man, thanx, it's what I need right now!!!

I only wrapped rgb() in doblequote, otherwise it dont worked.

I'm currently using this:

function imageapi_imagemagick_image_overlaytext_alpha(&$image, $text, $size = 12, $x = 0, $y = 0, $RGB, $fontfile = 'MgOpenModernaBold', $angle = 0) {
  if($angle != 0) {
    $image->ops[] = " -rotate ".$angle." -pointsize ".$size." -fill rgb\(".$RGB['red'].','.$RGB['green'].','.$RGB['blue']."\) -draw \"text ". ($x + 50) .",".$y." '$text'\" -rotate '.-($angle).";
  }
  else {
    $image->ops[] = " -pointsize ".$size." -fill rgb\(".$RGB['red'].','.$RGB['green'].','.$RGB['blue']."\) -draw \"text ". ($x + 50) .",".$y." '$text'\" ";
  }
  return true ;
}

Place the above in textactions.inc.

Notice that I escaped with \ the ( and ), used $text instead of Hello and added + 50 to the $x value.. yes.. this is very hacky but that's what was needed to place the text where I needed it to be.

Hope this helps someone,

@fax8 - Thanks for this. I needed to use ImageMagick for the PDF_to_ImageField module so this came in handy. I did get the following error when trying to use an angle.

ImageMagick reported an error: sh: -c: line 0: unexpected EOF while looking for matching `'' sh: -c: line 1: syntax error: unexpected end of file

But for this project using the angle is not a big deal so I emptied the field and it worked as expected.

With support of rotating.
Rotates relative to bottom left point of text box.

/**
 * Place text on an image.
 *
 * @ingroup imageapi
 */
function imageapi_imagemagick_image_overlaytext_alpha(&$image, $text, $size = 12, $x = 0, $y = 0, $RGB = 'black', $fontfile = 'MgOpenModernaBold', $angle = 0) {
    $alpha = ($RGB['alpha'] / 127) + 1;
    $color = 'rgb(' . $RGB['red']. ', ' . $RGB['green'] . ', ' . $RGB['blue'] . ', '. $alpha . ')';

    $action .= " -font \"$fontfile\" -pointsize \"$size\" -fill \"$color\" -draw 'translate $x,$y rotate $angle text 0,0 \"$text\"'";

    $image->ops[] = $action;
    
    return TRUE;
}
