Here is an inquiry concerning the usage of the drawImage() function.
var x = (i-j)*(img[0].height/2) + (ctx.canvas.width/2)-(img[0].width/2);
var y = (i+j)*(img[0].height/4);
abposx = x + offset_x;
abposy = y + offset_y;
ctx.drawImage(img[0], abposx, abposy);
This particular code snippet illustrates the drawing of an image within a canvas while incorporating an offset. My primary curiosity lies in understanding where exactly the "drawImage" function positions the image: is it based on the left corner of the image, or is it aligned with the center?
If the positioning is indeed determined by the left corner, I am interested in learning how to modify it so that the image is placed according to its center instead.
