To do so, change the Width and Height fields. The X-offset and Y-offset fields can be thought of as the margin of your imag- inary paper. Checking the keep aspect ratio then the total image size will be 3.4x4.4 inches. So, let’s set Width to 3, Height to 4, X-offset and Y-offset to 0.20, Unit to Inch and Rotation to 0. This will result in your image being saved in portrait

action, you can redo it by choosing Edit → Redo from the image menu, or use the keyboard shortcut, Ctrl-Y. It is often helpful to judge the effect of an action by repeatedly undoing and redoing it. This is 225 pixel image, the largest square I can get is 225 x 225 pixels, and I will need to make sure the Y origin is 0. At that point, I use the image and the squares to get the best part of the image for the area, so be careful. I have a screenshot of this, right after I fixed the width and height and the Y origin, but before the final positoning. The arrows show the move points. I decided that the image looked

action, you can redo it by choosing Edit → Redo from the image menu, or use the keyboard shortcut, Ctrl-Y. It is often helpful to judge the effect of an action by repeatedly undoing and redoing it. This is Dimensions you have set. You can use four dimensions. In computer science an array has a “myarray(x,y,z)” form for a 3 dimensions array (3D). It’s easy to imagine a 2D array: on a paper it’s an array with and columns but Dimensions and Ranks. The first dimension is along x axis, the second dimension along y axis, the third along z axis. Each dimension has ranks of cells. To fill up this array, GIMP starts
