Description
roFont is used in conjunction with roFontRegistry to create and manage fonts. Font files are registered with roFontRegistry and then various methods in roFontRegistry can be used to create roFont objects. Applications should not create roFonts with CreateObject() but should always use roFontRegistry to create them. roFont objects in turn can be used with ifDraw2D.DrawText to draw text on the screen or into bitmaps.
Example
screen = CreateObject("roScreen")
white = &hFFFFFFFF
blue = &h0000FFFF
font_registry = CreateObject("roFontRegistry")
font = font_registry.GetDefaultFont()
' Draw white text in a blue rectangle
text = "Hello world"
w = font.GetOneLineWidth(text, screen.GetWidth())
h = font.GetOneLineHeight()
x = 200
y = 100
border = 8
screen.DrawRect(x, y, w + 2*border, h + 2*border, blue)
screen.DrawText(text, x+border, y+border, white, font)
