最终输出应该像图像(HELLO WORLD):
这是我正在做的事情:-
$im = imagecreate(400,400);
$txtcol = imagecolorallocate($im, 0xFF, 0x00, 0x00);
$size = 20;
$txt = 'DUMMY TEXT';
$font = './font/Capriola-Regular.ttf';
/*two points for base line*/
$x1 = 50; $x2 = 300;
$y1 = 150; $y2 = 170;
/*bof finding line angle*/
$delta_x = $x2-$x1;
$delta_y = $y2-$y1;
$texangle = (rad2deg(atan2($delta_y,$delta_x)) * 180 / M_PI)-360;
/*eof finding the line angle*/
imageline($im,$x1,$y1,$x2,$y2,$txtcol); //Drawing line
imagettftext($im, $size, $texangle, $x1, $y1, $txtcol, $font, $txt); // Drawing text over line at line's angle
当前输出如下:
谁能告诉我的代码有什么问题?
谢谢
