# TFT_eSPI
Update 24th Feb 2018: Added antialiased font capability.
>>> This branch includes new antialiased font capability, this is a work-in-progress <<<
An Arduino IDE compatible graphics and fonts library for ESP8266 and ESP32 processors with a driver for ILI9341, ILI9163, ST7735 and S6D02A1 based TFT displays that support SPI.

I have made some changes that will be uploaded soon that improves sprite and image rendering performance by up to 3x faster on the ESP8266. These updates are currently being tested/debugged.
**2. Anti-aliased fonts - added 24/2/18**
**2. Anti-aliased fonts**
I have been experimenting with anti-aliased font files in "vlw" format generated by the free [Processing IDE](https://processing.org/) (see Tools folder). This IDE can be used to generate font files from your computer's font set and include **any** Unicode characters. This means Greek, Japanese and any other 16 bit Unicode glyphs can be included.

It would be possible to compress the vlw font files but the rendering performance to a TFT is still good when storing the font file(s) in SPIFFS.

Fonts with configurable size and containing any arbitrary characters, or range of characters, from the Unicode 16bit character set (i.e. Basic Multilingual Plane) can be included using a Processing sketch in the Tools folder of the library. The source font files can be from your PC or selected TrueType (*.ttf and *.otf) files.
Fonts are stored in the ESP8266 or ESP32 SPIFFS FLASH memory.
New examples have been added to demonstrate. At the moment these use the print class. Drawing characters with background over-write and printing in sprites is also supported but I have not included any examples yet.
Screenshot from one example below:

Currently these are generated from a sketch, but when I have the Alpha blending sorted for colour backgrounds the plan is to build the rendering code into the TFT_eSPI library. Watch this space " " for updates!
