Example 11b: Icons and spritesheets

In this example, we use a spritesheet to contain many, many icons that are used in hotspots, here depicting Local Storm Reports (which are dynamically generated, and use the fof_extention= parameter within the file_of_filenames).

Click here to see the 'spritesheet' image.

The sprites= parameter in the config file looks like this:
sprites=lsrsprite.png, row, 14,25,25, 1,30,20, 4,25,25, row, 16,25,32, 3,25,25,1,25,32, row, 20,25,32, row, 16, 25,32, 3,30,30, row, 20,25,32, row, 20,25,32, row, 20,25,32, row, 20,25,32, row, 20,25,32, row, 20,25,32, row, 20,25,32, row, 16,25,32, row, 20,25,32

One of the hotspot parameters in the fof_extension file looks like this:
hotspot=301.33,179.73,sprite,199,pan/1,popup, Event: SNOW Mag: Measured 0.2 INCH Time: 14 Dec 2016 at 08:00 CST City: 2 WSW CONIFER CO County: JEFFERSON Source: COCORAHS Remarks: ,Measured 0.2 INCH SNOW

The LSR display has been linked to overlay #1 ("LSR") and we use the 2nd overlay to display watches and warnings. Note that overlay #1 is an image that just contains some text showing that it is visible and to illustrate that the "hotspot" icons are displayed on top of the image.

We continue to use the "tooltip" of the hotspots and hotzones to display abreviated information, with details being shown when the user clicks on the spot or zone.

So....first enable the "LSR" overlay, and then hover over some of the icons. Click them to get a pop-up with details. Note also when you zoom in that the icons remain the same size and will separate the more you zoom in...
