高分求:网页生成印章~~~

在网页上生成一个章

1、你参考一下,

该处有原代码!

2、你再看看

该处有附件,试着做一下!

3、你也可以看看:

然后你打开该网页的源文件,参考一下,是不是也有灵感了!

其中核心部分代码为:

//.............................................//

function checkform(thisform){

var re;

var val;

val=thisform.showname.value;

if (val.length != 4)

{

alert("请输入您的印章文字,格式为4个汉字!");

thisform.showname.focus();

return false;

}

if (!strChina(val)){

alert("请输入您的印章文字,格式为4个汉字!");

thisform.showname.focus();

return false;

}

/*val=eval('thisform.imgtype');

if (!val[0].checked !val[1].checked){

alert("请选择印章的类型!");

val[0].focus();

return false;

}*/

val=eval('thisform.fontname');

if (!val[0].checked !val[1].checked !val[2].checked !val[3].checked !val[4].checked !val[5].checked){

alert("请选择印章文字的字体!");

val[0].focus();

return false;

}

return true;

}

function strChina(astr){

var lst = /[u00-uFF]/;

return !lst.test(astr);

}

Java或js实现动态生成椭圆电子章图片(非窗体程序)

现成写好的印章生成小工具源码,还支持椭圆、私章等。直通车:

怎样用软件制作一个印章印出来的图案?圆形的那种?

我用的是Adobe Photoshop CS。如果老兄会用这个软件的话应该不难,做一个圆形外框很简单,主要是里面的文字,这要用路径工具。用圆形选框工具画一选区,点路径下面的建立路径,点文字工具,将光标点中刚建立的路径(也就是你需要的文字起始位置)输入需 要的文字。文字大小、间距都可调,当然也可以根据文字调整圆圈的大小使之相合适,至于中间的五角星,我想只要会Photoshop 就不难做了
