If you have a website where you display photographies like in a portfolio, photo gallery, etc. this is the perfect PHP class to enhance your website or product.
With Histogram Generator Pro you can easily generate 4 different kinds of histograms: RGB Histogram, Red Channel Histogram, Blue Channel Histogram and Green Channel Histogram.
You can also choose to display between simpe or advanced histograms.
Simple histogram displays the histogram and includes the number of colors present in the image, the number of pixels in the image, and the percentage of overexposed and underexposed pixels.
The advanced mode histograms include extra details: standard deviation and average value in the histogram.
Besides generating histograms this script generates 4 copies of the original image. One for each channel (red, green and blue). So you can display the different channels of your RGB image.
Also a greyscale version of the original image is generated displaying the overexposed and underexposed pixels with special colors.
Pease see the screenshots for more details.
