Thread: Alert/Speedcam icons, what is it and how to change it

About once a week, someone will asked how to change/hide the alert/speedcam icons. Which the answers are posted many times already.

Spoiler: What is it?

There are 32 alert types that has their own icons to be shown on the map. For example, "speedcam" such as RedlightCamera
[Only registered and activated users can see links. ]
or "alerts" such as SchoolZone
[Only registered and activated users can see links. ]
Some people wants to change it or hide these icons. Note that they still want the alert/speedcam to work (visual and audio notification) just not displayed on the map.

Spoiler: How to...

There are .bmp files that are .spr (Sprite) containing the 32 icons graphics (for the 32 associated speedcam/alert types.) There are two sets: speedwarn0.bmp and speedwarn1.bmp (and their associate .spr files)
They are originally in data.zip/ui_nextgen/res/common/<res> where <res> are:
ldpi, mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi
They can also be in other .zip files such as "skins" and UX's. You have to track them down and changed the "last" one used by proggy to see the effect.
The .bmp files are originally in NNG RLE format and needs to be converted to Window BMP format so you can use a normal graphic editor to change it.
Understand how NNG sprite works at [Only registered and activated users can see links. ]
As an example, you can find my UX that "hide" Schoolzones (type=9) at [Only registered and activated users can see links. ]
