Problem with Sprite & pushimage const convertion

[ghostofperditi0n]

I'm having trouble pushing multiple images to sprites with esp32 on gc9a01 round display.
In particular, if I use tft.pushimage / push.rotate only with image called "tline" everything works;
Problem appear only on:
background.pushImage(165, 200, 16, 13, set, TFT_WHITE);
background.pushImage(62, 200, 16, 13, folder, TFT_WHITE);
giving:
Compilation error: _invalid conversion from 'const short unsigned int*' to 'uint16_t*' {aka 'short unsigned int* '} [-fpermissive]

Problem disappear drawing on tft using:
tft.pushImage(165, 200, 16, 13, set, TFT_WHITE);
tft.pushImage(62, 200, 16, 13, folder, TFT_WHITE);

In pics.h i upload in flash memory images converted with rinky dink like:

#if defined(AVR)
#include <avr/pgmspace.h>
#elif defined(PIC32MX)
#define PROGMEM
#elif defined(arm)
#define PROGMEM
#endif
const unsigned short thline[3360] PROGMEM={ 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, ecc ecc ecc ecc }
const unsigned short set[208] PROGMEM={ 0xC618, 0xFFFF, 0xFFFF, ecc ecc ecc ecc }
const unsigned short folder[208] PROGMEM={ 0xC618, 0xC618, 0xC618, 0xC618, ecc ecc ecc ecc }

I paste code:

#include <SPI.h>
#include <TFT_eSPI.h>
#include "pics.h"
TFT_eSPI tft = TFT_eSPI();
TFT_eSprite background = TFT_eSprite(&tft);
TFT_eSprite meter = TFT_eSprite(&tft);

void setup() {

tft.begin();
background.setColorDepth(8);
meter.setColorDepth(8);
tft.setRotation(2);
meter.createSprite(28,120);
background.createSprite(240,240);
tft.setSwapBytes(true);
meter.setSwapBytes(true);
background.setSwapBytes(true);
}

int thangle=270;

void loop() {

uint16_t contorno_color = 50776;
uint16_t bg_color = 6179;
background.fillScreen(bg_color);

meter.pushImage(0, 0, 28, 120, thline);
tft.setPivot(120,120);
meter.setPivot(14,120);
meter.pushRotated(&background, thangle, TFT_WHITE);

background.pushImage(165, 200, 16, 13, set, TFT_WHITE);
background.pushImage(62, 200, 16, 13, folder, TFT_WHITE);

background.pushSprite(0,0);
delay (5000);
meter.deleteSprite();
background.deleteSprite();
}

Any solutions / ideas ?
p.s. i was obliged to use :

background.setColorDepth(8);
because without i cannot visualize 240 x 240 ( fullscreen ) sprite;
without limiting bit dept i was able to visualize at max 239 * 239 pixel sprite. ( why ? )

background.pushImage(62, 200, 16, 13, folder, TFT_WHITE); ok seem that problem is the trasparency TFT_WHITE.
Without no problem, with TFT_WHITE, or 65535, or 0xFFFF or 0xFF no way.. invalid conversion error...
Someone can help me please ? thx

The sprite class does not have a function to push an image with a transparent colour. This should work:

background.pushImage(165, 200, 16, 13, set);
background.pushImage(62, 200, 16, 13, folder);

When the sprite is pushed to the screen a 16 bit transparent colour can be specified.
