ImagickDraw::setFontSize — Sets the font pointsize to use when annotating with text
Diese Funktion ist bis jetzt nicht dokumentiert. Es steht nur die Liste der Argumente zur Verfügung.
Sets the font pointsize to use when annotating with text.
the point size
Es wird kein Wert zurückgegeben.
The font size taken in parameter is not the size in point (1 point = 1/72 inch) but the font's height in pixel.
Therefore you should do a conversion to have the correct font size if you want to modify a document destined to print.
For example, if your document's resolution is 300ppi, you should add a 25/6 multiplying factor to your fontsize in order to have a correct behaviour of the font.
<?php
$sourceFile='in.jpg';
$textWrite='God is Great';
$x=50;
$y=50;
$fontColor='#000000';
$fontSize=34;
$colorPix=new ImagickPixel ($fontColor);
$image=new Imagick ($sourceFile);
$draw=new ImagickDraw();
$draw->setFontSize($fontSize);//Sets the font pointsize to use when annotating with text
$draw->setFillColor($colorPix);//Sets the fill color to be used for drawing filled objects
$image->annotateImage($draw,$x,$y,0,$textWrite);//Annotates an image with text
$image->writeImage('out.jpg');//Writes an image to the specified filename
?>
