Preview is automatic for some options but you will have to press this button to update Preview after modifying many other parameters.

When mouse pointer is on Preview and the Light tab is selected, it takes the form of a small hand to grab the blue point which marks light source origin and to displace it. This blue point may not be visible if light source has negative X and Y settings in the Light tab.

Zoom buttons allow you to enlarge or to reduce image in Preview. Their action is limited, but may be useful in case of a large image.

Puts a grid over the preview to make displacements and rotations more easy. Works well on a plan.

To have preview working as usual.

This drop-down list allows you to select the object the image will be mapped on. It can be a Plane, a Sphere, a Box or a Cylinder.

This option makes image transparent around the object. If not set, the background is filled with the current background color.

When moving Plane object and displacing it with Orientation tab options, a part of the image turns empty. By checking the Tile source image, source image copies will fill this empty space in. This option seems not to work with the other objects.

	Note
	This option works with “Plane” only.

When this option is checked, a new image is created with the result of the filter, preserving the original image.

When this option is checked, a new layer is created with the result of the filter, leaving the original layer unchanged. This has no effect if Create new image is also checked.

Enabling this setting allows you to remove or reduce the aliasing effect that can show up on borders. When checked, this enables the following settings:

If “Point light” is selected, you can control there light source Position (the blue point), according to X, Y and Z coordinates.

If “Directional light” is selected, these X, Y and Z parameters control the “Direction vector” (effect is not evident).

When Light Source Type is set to "Point Light", changing the X, Y, and Z values moves the "viewer" closer to or further from the object in those directions.

Note that this will not visually affect images set to "Plane" in the Map To field.

When Map To is set to "Plane", changing the X, Y, and Z values simulates the effect of tilting the plane on the Y and Z axes. This impacts how the Material tab settings affect the render.

These three sliders and their input boxes allows you to vary object position in image, according to the X, Y, Z coordinates of the object upper left corner.

These three sliders make the object rotate around X, Y, Z axes respectively.

Select an image for every face of the box. These images must be present on your screen when you call the Map Object filter.

These X, Y, Z sliders allow you to change the size of every X, Y, Z dimension of the box.

Select an image for every face of the cylinder. Images must be present on your screen when you call the Map Object filter.
