Adafruit GFX graphics core Arduino library, this is the 'core' class that all our other graphics libraries derive from
The purpose of this PR is 1. To reuse GFX_button object for On/Off Start/Stop operations to save memory and convenience. 2. Set Enable/Disable button to check for click and process...
If i want develop some ui and draw text to rectangle i need text size text color and selected font. i have two options inherit library which is not good...
This adds fine-grained control over font size by allowing specifying size in the 26.6 fractional points (1/64 pt). This can be achieved by multiplying size by 64 and adding `f`...
**I know you don't want new font formats. But font size is different, and the integer-only support makes this library a bit inflexible.** On my SSD1306 blue OLED display, font...
The provided code adds new library functions to draw arcs and filled arcs. It is based on existing circle drawing code. To realise the trigonometric functions a fixed-point math library...

Add optimized code for Spresense board using ifdef `ARDUINO_ARCH_SPRESENSE`. Tested to work on Spresense board. There is no impact on the other boards.
There are extensive comments in getTextBounds() header in the .cpp file. The arguments are pointers to places to return values, just like several already-existing arguments to the function. They have...
Allows user to draw thick circles without drawing multiple circles one after another. with the current master package, this can be done by overlaying a small cicle over the top...
Tested with BSP and ILI9341 SPI based display: * LGT8fx: https://github.com/dbuezas/lgt8fx * Nulllab: https://github.com/nulllaborg/arduino_nulllab Issue: SPI based displays work well with BitBang mode, but does not work with HW SPI....
