If you can't know the size in advance, then add onload listeners to your image and when it is loaded then measure its displayed dime...
byte + byte = int… why?
...
The third line of your code snippet:

Pointers vs. values in parameters and return values
...actical follow that pattern. Some tools like database interfaces or serializers need to append to a slice whose type isn't known at compile time. They sometimes accept a pointer to a slice in an interface{} parameter.
Maps, channels, strings, and function and interface values, like slices, are int...

Canvas width and height in HTML5
...dth="…" attributes. Set them to numeric values in JavaScript code to resize your canvas. For example:
var canvas = document.getElementsByTagName('canvas')[0];
canvas.width = 800;

For example, let's say you have a main function A in an m-file A.m, along with local functions D, E, and F. Now let's say you have two other related functions B and C in m-files B.m and C.m, re...
