Counting black pixels in an image ??

[studentrgu94]

I have a problem with the counting black pixels program at the very bottom and i dont know why its showing errors



#include <QCoreApplication>
#include <iostream>
#include "ImageHandle.h"

using namespace std;

void setBorder(unsigned char pixels[WIDTH][HEIGHT]);
void countblackpixels(unsigned char pixels[WIDTH][HEIGHT]);

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

unsigned char PixelGrid[WIDTH][HEIGHT]; // Image loaded from file
// unsigned char TitleGrid[WIDTH][MASKHEIGHT]; // Title overlay - needed for final function

// If the file "Parrot.png" cannot be loaded ...
if (!loadImage(PixelGrid, "Parrot.png"))
{
// Display an error message
cout << "Error loading file \"Parrot.png\"" << endl;
}
else
{
cout << "File \"Parrot.png\" opened successfully" << endl;

// Set the pixels in the top 15 rows to be black
setBorder(PixelGrid);
// Demo of use of saveImage - to save the modified file as "ParrotBorder.png"
if (saveImage(PixelGrid, "ParrotBorder.png"))
{
cout << "File \"ParrotBorder.png\" saved successfully" << endl;
}
else
{
cout << "Could not save \"ParrotBorder.png\"" << endl;
}
}

return a.exec();
}
