Text and Text8

Yeah these text subs might come in handy for labeling or jazzing up your print without loading a Font.

Text uses standard 8X16 chars in QB64 and Text8 uses the tiny _Font 8 square block characters.

Here I've updated them since Dav pointed to something and then I discovered background color was being changed. Hopefully all fixed and fit now.

Code: (Select All)

_Title "Text and Text8 tests" ' b+ 2024-11-01

Screen _NewImage(1024, 600, 32): _ScreenMove 0, 0
Color &HFFDDDDFF, &HFF000066: Cls
size = 64
For i = 1 To 20
    Text8 20, row, size, &HFF00FF88, "This is line" + Str$(i)
    row = row + size + 1
    size = 64 * .9 ^ i
Next
row = _Height - 64 - 8
size = 64
For i = 20 To 1 Step -1
    t$ = "This is line" + Str$(i)
    Text _Width - Len(t$) * size / 2 - 20, row, size, &HFFFF8800, "This is line" + Str$(i)
    size = 64 * .9 ^ (21 - i)
    row = row - size - 1
Next
_PrintString (350, _Height - 20), "OK tests done."
Sleep

Sub Text8 (x, y, textHeight, K As _Unsigned Long, txt$)
    Dim fg As _Unsigned Long, bg As _Unsigned Long, cur&, i&, f&
    fg = _DefaultColor: bg = _BackgroundColor: cur& = _Dest: f& = _Font
    i& = _NewImage(8 * Len(txt$), 8, 32)
    _Dest i&: _Font 8: Color K, _RGBA32(0, 0, 0, 0): _PrintString (0, 0), txt$
    _PutImage (x, y)-Step(Len(txt$) * textHeight, textHeight), i&, cur&
    Color fg, bg: _FreeImage i&: _Dest cur&: _Font f&
End Sub

Sub Text (x, y, textHeight, K As _Unsigned Long, txt$)
    Dim fg As _Unsigned Long, bg As _Unsigned Long, cur&, i&
    fg = _DefaultColor: bg = _BackgroundColor: cur& = _Dest
    i& = _NewImage(8 * Len(txt$), 16, 32)
    _Dest i&: Color K, _RGBA32(0, 0, 0, 0): _PrintString (0, 0), txt$

End Sub

Thanks to Phil and Steve for getting me to haul out Text and look it over again.
