Re: [Gimp-user] get raw histogram data for image, not just statistics

Is there another function that can return an array of the histogram? What's wrong with doing 256 PDB calls? Shouldn't take considerable time to complete. If you dislike this, you could also look at the pixel data and create the histogram yourself.

[Gimp-user] get raw histogram data for image, not just statistics
Hi, I would like to use the perl interface to automate processing of black and white images. I would like to set a threshold for white vs black on the images based upon the histogram without physically looking at each image. I dont want to do it using the gimp-gui. I would like to get an array consisting of the histogram hist[i] = count of pixels in image with intensity i. however the only function i see in the PDB is (mean,std_dev,median,pixels,count,percentile) = gimp_histogram (drawable,channel,start_range,end_range) which would require 256 calls of this function to get the data. Is there another function that can return an array of the histogram? My goal is to use the histogram to pick a threshold between gray background and text on a jpg image of a book page that I make a picture of with my digital camera. Thanks Mitchell I also posted this to usenet gimp group. I dont know how to avoid cross posting this. - Be a better Heartthrob. Get better relationship answers from someone who knows. Yahoo!
