超实用！用C语言在Dev中实现图像压缩编码算法

以下是一个简单的图像压缩编码的C语言算法实现： ```c #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX_SIZE 1000 void compressImage(char *input, char *output) { FILE *inFile = fopen(input, "rb"); FILE *outFile = fopen(output, "wb"); if (!inFile || !outFile) { perror("Error opening files"); return; } unsigned char buffer[MAX_SIZE]; int count = 0; unsigned char lastByte = 0; int repeatCount = 0; while (1) { int bytesRead = fread(buffer, 1, MAX_SIZE, inFile); if (bytesRead == 0) { break; } for (int i = 0; i < bytesRead; i++) { if (buffer[i] == lastByte) { repeatCount++; } else { if (repeatCount > 0) { fputc(0x90 + repeatCount, outFile); fputc(lastByte, outFile); } lastByte = buffer[i]; repeatCount = 1; } if (repeatCount == 255) { fputc(0x90 + repeatCount, outFile); fputc(lastByte, outFile); repeatCount = 0; } } } fclose(inFile); if (repeatCount > 0) { fputc(0x90 + repeatCount, outFile); fputc(lastByte, outFile); } fclose(outFile); } int main() { char *inputFile = "input.bmp"; char *outputFile = "output.dat"; compressImage(inputFile, outputFile); return 0; } ``` 这个算法通过检查连续重复的像素值来压缩图像数据，并将压缩后的数据写入到一个新文件中。要运行这个程序，需要将要压缩的图像文件（比如input.bmp）放在同一目录下，并在代码中指定输入文件和输出文件的文件名。然后编译运行代码，即可实现图像压缩编码。 ######[AI写代码神器 | 1169点数解答 | 2024-12-17 10:28:44]
