我如何逐行阅读图像？ [英] How I can read image line by line ?

问题描述

嘿朋友

请我使用visual studio c语言，

i想知道我如何逐行读取图像（输入图像像c中的文件）

例如图像512 * 512

逐行读取512行，每行将其保存在一个文件中:)

thnx：）



我尝试了什么：



i没有试过我想要一个想法

解决方案

这不是很多。如果您只想读取字节数，则可以使用文件i / o 并阅读512字节。



但有趣的是显示数据。比你必须正确访问像素。通常，x轴是直线，y轴是直线计数。首先准备足够大的图片，然后循环并设置像素。



CXImage文章是一篇杰出的文章，展示了所需技术的漏洞。

What I have tried:

i nothing tried i want just a idea

解决方案

That isnt much. If you only want to read the bytes than you can use the file i/o and read your 512 bytes.

But interesting gets the display of that data. Than you must access the pixels correctly. Normally the x-axis is a line and the y-axis is the line count. Prepare a big enough picture at first and than loop and set the pixels.

The CXImage article is an outstanding piece which demonstrates a hole bunch of the needed technology.
