在图像上绘制多条线 [英] draw multiple lines on image

问题描述

嗨！
我有一个图像(例如验证码图像).图像的背景是透明的.我想在c#中创建一个应用程序，从图像的开始垂直检查像素的颜色(比如说颜色检查器).这样就会出现一个地方，颜色检查器将到达图像的前两个字符之间，因此像素colm肯定会在该点为空，因此该应用将其保存到该点为止的png图像，然后再开始进行检查，并逐个保存字符.
有人可以告诉我该怎么做..?
在此先感谢

Hi!
i have an image(say captcha image).the background of image is transparent. i want to create an app in c# that check the color of pixels vertically from starting of the image(say color checker).so a point will come where the color checker will reach to between first two characters of image so definitely the pixel colm will be empty at that point, so the app saves it a an png image up to that point and start checking it again futher doing so and saving characters one by one.
can somebody tells me how this will be done..?
thanks in advance

推荐答案

正如我昨天解释的那样( ^ ])Captcha的整个想法是，机器阅读尽可能困难.垂直没有保证的空白行.或水平.请记住，验证码以不同的方式工作，有些是旋转的，有些则将字符混在一起，有些则使椭圆形区域的颜色反转，等等，所有或哪种方法会破坏您的算法".

您是一个失败者，试图打破验证码-在浪费太多时间之前就放弃.

As I explained yesterday (seperate characters of an image[^]) The whole idea of Captcha is that it is as difficult as possible for machines to read. There are no guaranteed blank lines vertically. Or horizontally. Remember, captcha work in different ways, some are rotated, others have the characters mashed together, others invert the colours in an oval area, and s forth an so forth, all or which methods will break your "algorithm".

You are on a loser, trying to break captchas - give up before you waste too much of your time.
