用法: intgetpixel(int x, int y); 注意:默认情况下,屏幕为黑色,因此(0,0)处像素的颜色为黑色。 下面是getpixel()函数的实现。 // C Implementation forgetpixel()#include<graphics.h>#include<stdio.h>// driver codeintmain(){// gm is Graphics mode
用于getpixel 的 C 程序 #include<graphics.h> #include<conio.h> main() { int gd = DETECT, gm, color; char array[50]; initgraph(&gd,&gm,"C:\\TC\\BGI"); color = getpixel(0, 0); sprintf(array,"color of pixel at (0,0) = %d",color); outtext(array); getch(); closegraph(...
} delay(DELAY_TIME); srand(seed); for (i=0; i<PIXEL_COUNT; i++) { x = random(maxx); y = random(maxy); color = random(maxcolor); if (color == getpixel(x,y)) putpixel(x,y,0); } } /* clean up */ getch(); closegraph(); return 0; }...

编写种子八连通区域填充算法C语言程序,设区域边界的颜色为bcolor,要填充的新颜色为ncolor。已定义函数int getpixel (int x,int y)返回(x,y)象素点颜色值;函数void putpixel (int x, int y,int color)在(x,y)象素点填入颜色color。(试填写程序段空格处) void fill(int x, int y, int ncolor, int b...
如果决定使用JNI，建议先用Java编写一个readJPG方法，再通过C调用它，而不是直接调用ImageIO.read。最后，如果目标是图像识别，建议不要使用JPG格式，因为它会丢失数据，导致精确识别变得困难。模糊识别可能需要较高的技术水平，并且效率较低。相较之下，BMP格式更适合图像识别，并且网上有大量的解码库和...
