    4545The current mouse coordinates in the image, as well as the local image intensity ('A'), are displayed in the upper right text window. The local image matrix  indices 'i' and 'j' are also displayed. By default the coordinates are expressed in pixel units, with origin (0,0) at the lower left of the image (the lower left pixel centre is at (0.5,0.5)). The x coordinate is equal to i-0.5 while the y coordinate is npy-(j-0.5), since the  image index j runs from top to bottom unlike the coordinate y. In case of low screen resolution, it is possible to duplicate this display in a bigger window, by right mouse button selection (after zoom has been desactivated). When the mouse is over an edit box or press button, its tag is displayed with a short explanation (tooltip). The tag and box string can be also displayed by selection with the right hand mouse button.

    47 The current image can be extracted for further processing with Matlab tools, for printing, saving, exporting ... Use the menu bar command '''[Export/extract figure]'''. It can be also exported  in the Matlab Command window as a Matlab variable (a structure), using the menu bar command '''[Export/extract field in workspace]'''. The displayed field is represented by the sub-structure Data_uvmat.Field available in the workspace: the image matrix is Data_uvmat.Field.A while the X and Y coordinates of the first and last pixels are represented by Data_uvmat.Field.AX and .AY respectively.
