Once an item is selected, it will be displayed on the open active page in the preview area and can be moved and scaled interactively with the mouse.

Move Element with the Mouse

If you move the mouse over the semitransparent element, the mouse pointer changes into a hand.
This indicates that the element can now be moved with the mouse button pressed.
There is no raster in this view, i.e. the element can be freely moved and positioned.

Scale Element with the Mouse

The item can also be resized as desired. Again smoothly with the mouse without any grid locks.
If you want to achieve an exact alignment, the elements (usually images and video) either can be positioned automatically in a layout grid (see Automatic Layout support), or via controls like margins, grid, various centering options, etc. offered in the Advanced Edit Window.

An element can be scaled up and down with the mouse by dragging the corners. The original aspect ratio is maintained.
An element also can be dragged on a side instead of a corner. In that case Then the content is distorted, i.e. the aspect ration changes. Please keep this in mind, because sometime the preview looks differently!

The following two examples illustrate this:

1. Example: Horizontally enlarged

Preview Width enlarged
Final Width enlarged

The preview is enlarged correctly but trimmed. In the final book the image is correct in size, but the content is distorted.

2. Example: vertically enlarged

Preview Height enlarged
Final Height enlarged

Again it looks like a section could be defined in dragging the side vertically (zoom in and clip). But the final Mz3 Book shows that again the image is distorted.

If you really have to make a picture fit and the distortion is minimal, then this possibility might be an option. But please remember that this way of “adjustment” results in distorted elements!

Background Info:
The option of scaling and cropping an image interactively with the mouse is not yet fully implemented and currently only “fakes” to work in mz3Tool.
The information required for MegaZine3 (the program presenting the final book) is not yet included in the mz3 configuration file.
It actually makes more sense creating an appropriately scaled/clipped copy of the element “offline” and then add it again with mz3Tool.
