Sprite in Background / Image with transparent elements in Forground

[T-Bone-one]

Hi, is it possible to display an image (in foreground) with transparent elements and a Sprite that is moving in the background ? So that the moving Sprite can only be seen when its position is on an transparent element. I cant find a demo for that. Can someone point me to this direction ,please ? .. Thanks

`#include <TFT_eSPI.h>
#include <SPI.h>
#include "SAI_graphics.h"
#include "background.h"

TFT_eSPI tft = TFT_eSPI();
TFT_eSprite bandSpr = TFT_eSprite(&tft);
TFT_eSprite backSpr = TFT_eSprite(&tft);

void setup() {
tft.init();
tft.setSwapBytes(true);
tft.setRotation(1);
tft.fillScreen(TFT_TRANSPARENT);

plotGauge();
}

void loop() {
}

void plotGauge() {
createBand();
// createBackground();
bandSpr.pushSprite(135, 0);
// backSpr.pushSprite(0, 0);
}

// void createBackground() {
// backSpr.setColorDepth(8);
// backSpr.deleteSprite();
// backSpr.createSprite(344, 320);
// //backSpr.setPivot(240, 160);
// backSpr.fillSprite(TFT_TRANSPARENT);
// backSpr.setSwapBytes(true);
// backSpr.pushImage(0, 0, 344, 320, SAI_back);
// }

void createBand() {
bandSpr.deleteSprite();
bandSpr.setColorDepth(8);
bandSpr.createSprite(240, 320);
bandSpr.setPivot(240, 160);
bandSpr.fillSprite(TFT_TRANSPARENT);
bandSpr.setSwapBytes(true);
bandSpr.pushImage(0, 0, 240, 1012, SAI_band);
tft.pushImage(75, 0, 344, 320, SAI_back);
