The GmagickPixel::getcolorcount() function is an inbuilt function in PHP which is used to get the color count associated with the pixel color. A color count is the number of pixels in the image that have the same color as this GmagickPixel. The getcolorcount() appears to only work for GmagickPixel objects created through getimagehistogram() function.
Syntax:
int GmagickPixel::getcolorcount( void )
Parameters: This function doesn’t accept any parameters.
Return Value: This function returns an integer containing the color count.
Exceptions: This function throws GmagickPixelException on error.
Below given programs illustrate the GmagickPixel::getcolorcount() function in PHP:
Used Image:
Program 1:
<?php   // Create a new Gmagick object $gmagick = new Gmagick('neveropen.png');   // Get the image histogram (image as array of gmagickpixels) $histogramElements = $gmagick->getImageHistogram();     // Get the last index $lastIndex = count($histogramElements) - 1;     // Get the last element from array which is  // a gmagickPixel object $lastColor = $histogramElements[$lastIndex];     // Get the Color count echo $lastColor->getcolorcount(); ?> |
Output:
100064
Program 2:
<?php   // Create a new Gmagick object $gmagick = new Gmagick('neveropen.png');   // Get the image histogram (image as array of gmagickpixels) $histogramElements = $gmagick->getImageHistogram();   // Get the first element from array which is  // a gmagickPixel object $firstColor = $histogramElements[0];     // Get the Color count echo $firstColor->getcolorcount(); ?> |
Output:
1
Program 3:
<?php   // Create a new Gmagick object $gmagick = new Gmagick('neveropen.png');   // Get the image histogram (image as array of gmagickpixels) $histogramElements = $gmagick->getImageHistogram();   // Get the whole color stats echo "R G B Hue :Count<br>"; foreach ($histogramElements as $pixel) {     $colors = $pixel->getcolor(true);     foreach ($colors as $color) {         print($color . " ");     }     print(":" . $pixel->getcolorcount() . "<br>"); } ?> |
Output:
R G B Hue :Count 0 22 35 :1 0 24 37 :1 0 25 37 :1 0 31 43 :1 0 32 44 :1 0 33 45 :1 0 36 48 :1 0 37 49 :3 . . .
