note 77739 added to function.imagettftext

Comment to: Sohel Taslim (03-Aug-2007 06:19) Thanks for the function which I have modified a bit. In the new version the lines have equal space between them (the g's in your example create bigger space between the lines) - set by the parameter '$Leading'. I have used the for-loop for better performance and slimmed the rest a little :) /** * @name : makeImageF * * Function for create image from text with selected font. Justify text in image (0-Left, 1-Right, 2-Center). * * @param String $text : String to convert into the Image. * @param String $font : Font name of the text.
