[AlexanderTonn]

:bug: Describe the bug

• it's not possible to use the whole space of the display
• graphics which larger than 255 in height or/and width can't be printed

 :bangbang: To Reproduce**

:interrobang: Expected behavior

To fix this i have to change the passing parameters of the drawImage() function

// #######
// ILI9341: CONVERT char Array to Image on Screen
// #######
// Function for drawing the img
- void drawImage(const char* cImgArray, byte byHeight, byte byWidth, byte byX, byte byY) {
+ void drawImage(const char* cImgArray, uint16_t uiHeight, uint16_t uiWidth, uint16_t uiX, uint16_t uiY) {
  // Transmit picture data onto screen  for each line
-  for (int y = 0; y < byHeight; y++) {
-    for (int x = 0; x < byWidth; x++) {
-      int index = y * byWidth + x;
+   for (int y = 0; y < uiHeight; y++) {
+    for (int x = 0; x < uiWidth; x++) {
+      int index = y * uiWidth + x;
      uint8_t pixel = pgm_read_byte(&cImgArray[index]);
      uint16_t color = convertPixelToColor(pixel);
-      tft.drawPixel(byX + x, byY + y, color);
+      tft.drawPixel(uiX + x, uiY + y, color);
    }
  }
}
