Hello * I've a performance problem using a simple scan line flood fill image with perl. With 800x600 colour pictures coming from SEM microanalisys I would like to engage porosity into the image so I started with a simple x,y loop. The problem here is that requires too much seconds to scan and produce the new colored image. At the moment I use imlib2 to read and write pixel color.
I'm new to PDL and I cannot believe that it's true...it's so powerful!! I don't how can I use PDL to speed up my scan. Do you know how to flood fill images or count porosity, engage color range and so on? I can use boolean intersection between 2 sets, the firs my picture the second a color mask but this close to 1 color, I've a range to parse because I have to take into account the error (like the fuzzy option in magickperl floodfill), that will be: my picked pixel color +/- error range so I don't understand how to use matrix solution. May you help me please? Thank you in advance, Luca
