php制作公司五章,圆形印章和椭圆形印章,正方形印章

发布时间：2023-09-06 01:24责任编辑：白小东关键词：暂无标签

都是写死的,代码重复太多,没有搜到椭圆的文字均匀分布的,数学也不好,有哪位大神能算一下.

function signtest(){
???????$name = "北京市阿斯达四大有限责任公司";
???????$path = $_SERVER["DOCUMENT_ROOT"] . ‘/data/sign/‘ . date("Y") . "/" . date("m") . "/". date("d") . "/";
???????mkdir($path,0755,true);
???????$filename = uniqid();
???????$picpath = $path . $filename;
???????Vendor(‘signcom‘);
???????$cc = new \circleSeal($name);
???????$sealname = ‘‘;
???????for($i=1;$i<4;$i++){
???????????if($i==2) {
???????????????$sealname = ‘财务专用章‘;
???????????}elseif($i==3){
???????????????$sealname = ‘合同专用章‘;
???????????}
???????????$cc->saveImg($picpath.".$i.jpg",$sealname);
???????}
???????$cc->saveEll($picpath.".4.jpg",‘发票专用章‘);
???????$cc->saveSquare($picpath.".5.jpg",‘王丽‘);
