用C/C ++和图形处理图像? [英] Image handling in c/c++ and graphics?

问题描述

大家好，
在开始写问题之前，我想弄清楚这是我的第一篇文章，并且我真的是编程方面的新手.我刚学过C(即字符串操作，数组n全部).我使用非常老版本的turbo C编译器(蓝屏:P，现在我知道这些天了)(因为我的朋友告诉我，它易于使用，并且使用C可以执行其他编译器可以执行的任何操作).我必须承认这真的很容易理解.

现在，我想制作一个将图像作为输入n的程序，并通过一些编辑(例如放大/缩小)将图像作为输入.我不知道从哪里开始.

所以我的问题是:使用C n编译器是否可以输入图像并将其像素存储在数组coz中，所以我尝试过的所有库(例如magick ++，opencv，CImg)在编译期间都会出错，因此我认为它们与该编译器不兼容.

在进行更多Google搜索之后，我遇到了以下代码:

hi all,
Before I start writing my question I want to make it clear that this is my first post and I am really newbie in programming. I just learned C (i.e string manipulation, array n all). I use very old version of turbo C compiler ( blue screen:P now I know its antique these dayz) (coz my friend told me that its easy to use and with C you can do anything which other compiler can do). I have to admit it was really easy to understand.

Now I want to make a program which takes image as an input n also give image as an input with some editing like zoom in/out. I dont know where to start.

So my question is: Is it possible with C n this compiler to input image and store its pixel in array coz all libraries ( like magick++, opencv, CImg) I tried gives error during compilation, so I think they r not compatible with this compiler.

After some more google search I came around this code:

FILE *fp;
unsigned char *bufferImmagine;
bufferImmagine=new unsigned char [dimX*dimY*3];
fp=fopen(argv[1],"r");
fread (bufferImmagine,dimX*dimY*3,1,fp);

但我什么都不懂.所以也请帮忙.

我的最后一个问题是:
我现在想学习图形处理和C ++.因此，请向我建议一个好的方法和一个好的编译器.是我坚持使用此turbo c ++，还是使用borland或VC ++的新版本?
n还告诉我这些编译器有什么区别?

谢谢您的问候

but I can''t understand anything in it. So please help here also.

and my last question is:
I want to learn graphic handling and c++ now. So please suggest me a good way and a good compiler. whether I stick with this turbo c++, or use new version of borland or VC++??
n also tell me what is the difference between these compilers??

thanks n regard

推荐答案

您是从错误的起点着手解决此问题的.您说您不理解上面发布的代码段，这是相当简单的C代码.在转向图形之前，最好花一些时间学习文件处理和Windows编程的基础知识.至于要使用哪种编译器，我建议您使用Microsoft的C ++编译器，您可以免费获得 ^ ].

You are approaching this problem from the wrong starting point. You say that you do not understand the code snippet posted above, which is a fairly simple piece of C code. You would be better spending some time learning the basics of file handling and Windows programming before moving on to graphics. As to which compiler to use I would suggest Microsoft''s C++ compiler which you can get free here[^].

您不能直接将图像包含在c ++中.
问题的最后一个答案是，您将turbo c ++用于图形，并且为了倾斜图形，您更喜欢在c中使用书籍图形.

you can not directly include the image in the c++.
and the last ans of your question is that you use the turbo c++ for the graphic and for leaning the graphic you can prefer the book graphic in c.
