#740: To avoid ambiguity the pushSprite for writing a sprite to another sprite has been renamed pushToSprite
#704: Change to 18 bit colurs for SSD1963 with SPI interface
Remove outdated TFT_SPIFFS_Jpeg example
New function added:
bool created(void);
to check if sprite has been rotated. Example:
if ( !spr.created() ) Serial.println("Sprite has not been created");
Read_User_Setup updated to be compatible with STM32 and new structure format.
Reduction in compiler warnings
Update Sprite destructor
Update version to 2.2.1
Added 24 bit colour handling alphaBlend to reduce precision loss in multiple blend stages (e.g. in 2D colour gradients). Added option for alpha dither to reduce colour banding in gradients with 16 bit colours.
Get rid of compile warnings.
The library has been cleaned up as it has got a bit untidy due to the large number of small incremental changes.
4bit Sprite examples renaed to be consistent with others.
alphaBlend example moved to generic folder (alphaBlend fn was moved to TFT_eSPI class).
Added sections + explanatory comments to functions prototypes.
Temporary comments added for potential gotchas for noobs when using DMA.
spi_begin/end functions renamed to reflect functionality. Old fns retained for backwards compatibility with user setup.h files.
Set font for Transparent_Sprite_Demo_Colormap to correct value (4)
renamed setColorMap to createPalette
renamed cmpPixel to readPixelValue
added setPaletteColor / getPaletteColor
added error check to createPalette
Callback allows anitaliased fonts to be rendered over colour gradients
or images.
"Smooth_font_reading_TFT" example added
"Smooth_font_gradient" example added
Minor changes to avoid signed/unsigned comparison warnings.
Added SD card storage for smooth fonts with ESP32
ESP32 will use PSRAM (if available and enabled) to hold smooth font
metrics
Improve performance of ESP32 Sprite shared functions
Add basic ST7789 driver option
Latent bug fixes for pin mask
Pixel function used wrong width and height for bounds check.
Remove String variable in smooth font code (not used)
Correct ESP8266UncannyEyes example for new setAddrWindow parameters
The touch screen handler was broken for the ESP8266 only. The library
uses SPI write only configuration for ESP8266 so the SPI buffer can be
recycled and it was left in write only mode. The library now switches
back to read & write mode at the end of a transaction.
Adafruit_GFX font support extended to Unidode Basic Multilingual Plane
Print stream deocdes UTF-8
Smooth font ascent and descent (affects line spacing) changed to rely on
metrics provided by Processing IDE (issue #303)
Bug fix for font rendering with no background on RLE native fonts
Supports Adafruit_GFX compatible font format with characters in the range 32-255.
Note that the font rendering functions expect UTF-8 encoded characters/strings.
