|

// DETAILED USAGE:
|

//
|

// Scale:
|

// Select how high you want the font to be, in points or pixels.
|
||||
// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
|
||||
// a scale factor SF that will be used by all other functions.
|
||||
//
|
||||
// Baseline:
|
||||
// You need to select a y-coordinate that is the baseline of where
|
||||
// your text will appear. Call GetFontBoundingBox to get the baseline-relative
|
||||
// bounding box for all characters. SF*-y0 will be the distance in pixels
|
||||
// that the worst-case character could extend above the baseline, so if
|
||||
// you want the top edge of characters to appear at the top of the
|
||||
// screen where y=0, then you would set the baseline to SF*-y0.
|
||||
//
|
||||
// Current point:
|
||||
// Set the current point where the first character will appear. The
|
||||
// first character could extend left of the current point; this is font
|
||||
// dependent. You can either choose a current point that is the leftmost
|
||||
// point and hope, or add some padding, or check the bounding box or
|
||||
// left-side-bearing of the first character to be displayed and set
|
||||
// the current point based on that.
|
||||
//
|
||||
// Displaying a character:
|
||||
// Compute the bounding box of the character. It will contain signed values
|
||||
// relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
|
||||
// then the character should be displayed in the rectangle from
|
||||
// <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
