New function added:
bool created(void);
to check if sprite has been rotated. Example:
if ( !spr.created() ) Serial.println("Sprite has not been created");
TFT_eFEX also needs updating so Rotated_Sprite_3 example renders correctly.
pushImage for FLASH images updated so partly off-screen images are correctly rendered.
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
Typical use to disable use of PSRAM for the sprite storage:
sprite.setAttribute(PSRAM_ENABLE, false); // true to enable
Minor update for recent button class update
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.
Corrected font 2 rendering issue #402
Corrected NULL pointer issue #400
Changed grave ` character (key for this character is left of numeral 1
key) to degree symbol in font 2
Change setup24 so DC pin is not D3
- When the post-remapped coordinates exceed screen bounds, `getTouch()` was returning a "valid" status without updating the coordinates. This would result in spurious touch detection events at the screen boundaries.
- The fix ensures that the return value is set to "invalid" in this boundary condition.
Added SD card storage for smooth fonts with ESP32
ESP32 will use PSRAM (if available and enabled) to hold smooth font
