TftPrintSndInteger() | TFT & EPD Graphic Library 2

Syntax

TftPrintSndInteger(sdInteger As SDword, bDigits 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
sdInteger	signed integer value to print
bDigits	number of significant digits to print

Overview

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

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 first character

wY_Pos — y position (absolute) 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 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 integer using an SND font.

Example

TftPrintSndInteger(-12345, 7, 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 approach is slower than using a background color.

-For specific formatting, you can use built-in functions in Positron's Str$... and print the resulting string using TftPrintSndString().

-Refer to TftPrintBdfInteger() and TftPrintSndString() for example parameter usage.
