PHP:创建一个平滑的边缘,图像或字体? [英] PHP: creating a smooth edged circle, image or font?
问题描述
我用过:
<?php
imagefilledellipse($ image,$ cx,$ cy,$ w,$ h,$ color);
?>
但讨厌它产生的粗糙边缘。所以我正在考虑制作或使用我将要输出的圆形字体:
<?php
imagettftext ($ image,$ size,$ angle,$ x,$ y,$ color,'fontfile.ttf',$ text);
?>
这样字体会产生一个光滑边缘的圆。我的问题是使字体大小匹配半径大小。
任何想法?或者,也许一个PHP的类,会产生圆滑的边缘将是伟大的!
谢谢。
聪明的想法,我喜欢!
但是,也许这个PHP类已经做到了:用于PHP(GD)的Antialiased填充弧/椭圆
在很多情况下,网站需要动态创建的图像:饼图,圆角,菜单按钮等。这个列表是无止境的。 PHP,或者更确切的说是GD库,提供了椭圆弧和椭圆,但是没有反锯齿。因此,我写了一个PHP函数,用PHP轻松地呈现填充的抗锯齿椭圆弧或填充抗锯齿椭圆(以及圆..)。绘制这些填充弧线现在是一个单线。
I'm making a PHP image script that will create circles at a given radius.
I used:
<?php
imagefilledellipse ( $image, $cx, $cy, $w, $h, $color );
?>
but hate the rough edges it produces. So I was thinking of making or using a circle font that I will output using:
<?php
imagettftext ( $image, $size, $angle, $x, $y, $color, 'fontfile.ttf', $text );
?>
So that the font will produce a circle that has a smooth edge. My problem is making the "font size" match the "radius size".
Any ideas? Or maybe a PHP class that will produce a smooth edge on a circle would be great!
Thank you.
Clever idea, I like that!
But maybe this PHP class already does the trick: Antialiased filled Arcs/Ellipses for PHP (GD)
In many cases websites need dynamically created images: pie charts, rounded corners, menu buttons, etc. This list is endless. PHP, or more precisely the GD library, provides filled elliptical arcs and ellipses, but they are not antialiased. Therefore I have written a PHP function to render filled antialiased elliptical arcs or filled antialiased ellipses (as well as circles..) with PHP easily. Drawing these filled arcs is now a one-liner.
