Mosaic

When the acquisition device does not capture the full image of a slice in one shot, several overlapped pictures of the same slice can be taken. The Mosaic tool allows translation and rotatation of the pictures that comprise a slice to build a single coherent image of the section. To build a sequence with slices composed of several images, it is strongly recommended to store the images organized in subfolders during the acquisition process and then to create the sequence in BioVis3D in such a way that every slice contains its images. For details on how to create a sequence to use the mosaic tool see Create a Sequence - Select Image Files.

To use the Mosaic tool, open a slice and then select Edit Mosaic from the Mosaic main menu (see Figure 1). Figure 2 shows a window where the Mosaic tool is active.

Figure 2: The Mosaic Tool.  

When a sequence is created using the Sequence Creation Wizard organizing images in subfolders, BioVis3D places the images of each slice on the top left corner, sligthly shifted with respect to each other, as shown in Figure 2.

The features available when the Mosaic tool is active are the following ones:

        Add an image to the mosaic.

        Delete images from the mosaic.

       Resize the mosaic area.

        Arrange images: alter the relative order of images to control the way they overlap.

        Align images: translate and rotate images use of transparency.
