Image X And Y Coordinates. We embed multiple images in a single image to save load time of the web page. In the second step i performed all the above arithmetic operation in reverse and got the original x and y coordinates matrices separately.

For example if you want to reference the image a that matt mentioned to the default intrinsic coordinate system used by matlab in which the center of the first pixel is located at position 1 1 and each pixel has an extent of one unit you could use the following syntax of imref2d. P1 3 1 p2 5 2 are two points in ii iv quadrant respectively then their images are q1 3 1 q2 5 2 in iii i quadrant respectively. Images play a very important role while designing a website.
Scale all coordinates by entering a multiply factor.
In the second step i performed all the above arithmetic operation in reverse and got the original x and y coordinates matrices separately. The following code is in the page header. If the image was resized the recorded mouse coordinates are recalculated to its original image scale. Scale factor 0 5 and coordinate 10 4.
