TftPrintSndDecimal() | TFT & EPD Graphic Library 2

Syntax

TftPrintSndDecimal(fDec As Float, bSigDigits As Byte, bDecDigits As Byte, bFontSize As Byte, wX_Pos As Word, wY_Pos As Word, pPosition As Bit, wForeColor As Word, wBackColor As Word, pTransparent As Bit)

Parameters

Parameter	Description
fDec	signed decimal value to print
bSigDigits	number of significant digits to print

Overview

If bSigDigits is larger than the number of significant digits, leading zeros will be added.
If bSigDigits is smaller than the number of significant digits, only bSigDigits digits will be printed.
If bSigDigits = 0, the number of significant digits will be automatically determined.

bDecDigits — number of decimal digits to print

If bDecDigits is larger than the number of decimal digits, trailing zeros will be added.
If bDecDigits is smaller than the number of decimal digits, only bDecDigits digits will be printed.
If bDecDigits = 0, a signed integer will be printed instead.

bFontSize — font size

0 or 1 = nominal size
2, 3, 4, ... = multiples of the nominal size

wX_Pos — x position (absolute) for the lower-left corner of the character

wY_Pos — y position (absolute) for the lower-left corner of the 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 for the glyph pixels

wBackColor — background color in 16-bit RGB565 format - used for empty pixels within the glyph's bounding box

pTransparent — transparency option

1 = Yes (use transparency)
0 = No (use background color)

Prints a signed decimal using an SND font.

Example

TftPrintSndDecimal(-12345.678, 7, 4, 2, 1, 1, 0, WHITE, BLACK, 0)

Notes

-Background color (wBackColor) will be ignored if transparency is enabled, and only the pixels from the glyph will be printed.
However, this method is slower than using a background color.
