Image Tool Bar Functions
The Image Tool Bar offers multiple functions to make the process of producing results easier.
If the Custom Zoom icon is available in the Image Zone, the image can also be zoomed to preset values by clicking on the arrow to the right of the zoom window containing the numeric "100". This calls up a drop-down dialog of available preset values. Typing a percentage value in this box and pressing the Enter key will also set the zoom factor.
If the Custom Zoom Icon is not visible, open the Image , select Options… and check the box next to the Custom Zoom Icon.
TAG Heuer by Lynx has the ability to automatically find the next object in the image. Clicking on the Find Object icon will search the image for the next likely object of interest in the image. This is most useful in larger images, or in cases such as pari-mutuel racing where it is desirable to leave the blank space in the image.
Position the cross hair at the center of the area of the image you wish to enlarge. Click on the zoom in icon marked with a “+”. This will zoom in 2x on the picture. Clicking the zoom out icon marked with “-” zooms back out.
It should be noticed that after a while of zooming in, the picture becomes very jagged or pixellated. How much the image can be magnified before this happens is tied to the height of the image as it was taken, and also related to the size of the file. There is a very simple trade-off between image quality and the size of the stored image on disk: the more information is kept, i.e. the bigger the file, the clearer the image stays at high magnification.
These features allow the operator to center a particular part of an image by pointing the cross hair at it and then zooming in or out. Perhaps even more useful, it can be used to keep track of the last object that results were entered for while scrolling through a long picture.

The aspect ratio control can be used to indicate the effective frame rate of displayed TAG Heuer by Lynx images. By default, the edit box displays the camera frame rate which indicates no aspect ratio change. Entering a different frame rate will cause the image aspect ratio to change by modifying the vertical dimension. This can be useful to adjust the look of an image captured at a frame rate a little too fast or too slow before displaying the image on a video board for example.
NOTE: You can also specify the zoom level to apply to the vertical dimension by appending % to the number. For example, entering '200%' will double the height of the image (the equivalent of halving the frame rate). Alternatively, entering a number with 'h' appended creates the effective frame rate by stretching or compressing horizontally. Entering a number with 'H' appended means to zoom horizontally by that percentage.
