Map Units

Tinderbox uses the same units for a number of Map view related attributes:

• icon sizes
  • $Width
  • $Height
• map co-ordinates
  • $Xpos
  • $Ypos
• viewport positioning co-ordinates
  • $MapScrollX
  • $MapScrollY
• container title bar depth (vs. viewport)
  • $TitleHeight
• fill configuration
  • $FillOffsetY

When used for position, attributes use two unit values to give Map co-ordinates.

Whereas co-ordinate values may be positive of negative, for basic sizing positive values should always be specified.

Note: the following applies to v5.x or earlier and will likely not be accurate with 4k displays. To map Tinderbox units to pixels use this formula: (N*36)-4 where N is the map unit figure. Thus 3 map unit = (3*36)-4 = 104 pixels. The '-4' adjustment is because Tinderbox allows a 2 pixel 'outer' buffer all round. As this buffer area never overlaps during automatic spacing of notes, it ensures at least a minimum 4 pixels gap between map icons.
