My name is also Beej. I'm in Software Engineering and I get a lot of classmates asking if I wrote your network programming guide ^_^ Quite the coincidence. Cheers! Hey Beej!

Good job! Having been a long time Slackware user, since 1996, and more recently an Arch user, I would say this comparison is very fair to both distributions and “spot on”. Good job!

By the time the data gets exposed, it's already abstracted. :-/ @brock I’m unaware of a way to get this low level data from the PNG, short of writing a PNG decoder in JS, and even then, my JS-fu isn’t strong enough to know a way to get the binary data in JS.

I have images where the values (0-255) in the raw pixels have an actual data meaning. Depending on the time of year, the actual index palette changes, (so the displayed colors change) but not the 0-255 values in each pixel. I can do this client side, but with overhead which I don't want. What I want to do is a browser side calculation. So when a user mouses over an image, the x,y provides the pixel needed, and the 0-255 is extracted. This is then converted to a data value (using a know formula,) which can be displayed for the user (and of course, a coresponding lat long which can be determined since I know the outer lat/long bounds of the image) Is it possible to get the raw pixel value of an 8-bit indexed png, not the associated RGBA?

Looks like you've cracked the main part of the problem. Are you still doing any work on it? If not would you be willing to share your source files? Best wishes Pete Hi
