TftPrintSndString(sString As sTftString, bFontSize As Byte, wX_Pos As Word, wY_Pos As Word, pPosition As Bit, wForeColor As Word, wBackColor As Word, pTransparent As Bit)


sString = null-terminated string to print (up to 72 characters)

bFontSize = font size

• 0 or 1 = nominal size

• 2, 3, 4, ... = multiples of the nominal size

wX_Pos = x position for the lower left corner of the first character

wY_Pos = y position for the lower left corner of the first character

pPosition = position type for the lower left corner of the character

• 0 = absolute, actual pixel position on the TFT screen (e.g., wX_Pos = 152, wY_Pos = 86)

• 1 = relative, based on the virtual division of the TFT screen into columns and rows (calculated by FontPixels and FontSpace) (e.g., wX_Pos = 5, wY_Pos = 2; with FontPixels = 8 and FontSpace = 9, the actual position would be x = 5 * 8 = 40; y = 2 * 9 = 18)

wForeColor = character color in 16-bit RGB565 format - used to set pixels forming the glyph

wBackColor = background color in 16-bit RGB565 format - empty pixels within the glyph's bounding box will use this color

pTransparent = transparency option

• 1 = Yes (use transparency)

• 0 = No (use background color)


Print string using SND font.


Example:

TftPrintSndString("TEST", 2, 1, 1, 0, WHITE, BLACK, 0)


Note: If transparency is enabled, the background color (wBackColor) will be ignored, and only the pixels of the glyph will be printed. However, this is slower than using a background color.
