The library provides access to compact font files, with fully scaleable anti-aliased glyphs. Here the smooth arcs have been used to create anti-aliased meter gauges on a 320x240 TFT:Īn excellent new compatible library is available which can render TrueType fonts on a TFT screen (or into a sprite). Here are two demo images, on the left smooth (anti-aliased) arcs with rounded ends, the image to the right is the same resolution (grabbed from the same 240x240 TFT) with the smoothing diasbled (no anti-aliasing): The arc drawing algorithm uses an optimised fixed point sqrt() function to improve performance on processors that do not have a hardware Floating Point Unit (e.g. Arcs can be drawn with or without anti-aliasing (which will then render faster). New sketches are provided in the 'Smooth Graphics' examples folder. New functions have been added to draw smooth (antialiased) arcs, circles, and rounded rectangle outlines. The 'RPi' interface style boards are now supported with the ESP32 S3. New board setup files have been added for the Seeed XIAO with round display, LilyGo T-Embed S3, LilyGo_T_QT_Pro_S3, ESP32 S3 Box and ESP32_S3_Box_Lite.

The automatic opening of the font folder can also be disabled within the Processing sketch. The Create_font Processing sketch has been updated to automatically create a complete C header file. Use the 'Issues' tab only for problems with the library.

A 'Discussions' facility has been added for Q&A etc.
