Naming conventions for bitmap files

Name of each bitmap should begin with number.  This number represents Bitmap size index (BSI). BSI is automatically computed from screen resolution or preset from settings.ini (key IconSize).

Sygic DRIVE defines following size indexes

• 1 = 100% (screen resolution 320x240 px)
• 2 = 130% (screen resolution 480x272 px)
• 3 = 150% (screen resolution 480x320 px)
• 4 = 200% (screen resolution 640x480 px)
• 5 = 250% (screen resolution 800x600 px)
• 6 = 300% (screen resolution 1024x768 px)

Example of naming convention for one Icon:

• 1_myIcon.bmp
• 2_myIcon.bmp
• 3_myIcon.bmp
• 4_myIcon.bmp
• 5_myIcon.bmp
• 6_myIcon.bmp

If the bitmap is used as POI icon, in case of POI warning the used icon index is greater by 2. For POI icons the Index 7 and 8 is supported as well.
