drawBmp() displays cropped image

[TheRegularDX]

Environment ( 実行環境 )

• MCU or Board name: ESP32-2432S028
• Panel Driver IC: ILI9341
• Bus type: SPI
• LovyanGFX version: latest
• FrameWork version: ArduinoESP32 v2.0.3
• Build Environment: PlatformIO
• Operating System: macOS

Problem Description ( 問題の内容 )

loading an image from an sd card and displaying it with drawBmp() results in a cropped image being displayed on the lcd, specifically only the bottom portion of the image. ive tried other pictures but got the same result.

Expected Behavior ( 期待される動作 )

a full image gets displayed on the lcd

Actual Behavior ( 実際の動作 )

cropped image gets displayed.

Steps to reproduce ( 再現のための前提条件 )

1. init display
2. init sd card
3. load an image and display it like this:

auto file = SD.open("/1.bmp");	
lcd.drawBmp(&file, 100, 50);

// frankenstein code from many examples and tutorials. 
// i am a beginner and this was a bit hard to set up. 
// loyvan if possible please improve the documentation thank you

    return 1;
  }
  uint8_t cardType = SD.cardType();

  if (cardType == CARD_NONE)
  {
    Serial.println("No TF card attached");
    return 1;
  }
  return 0;
}


void setup(void)
{
  Serial.begin(115200);
  lcd.init();
  lcd.setRotation(1);
  lcd.setBrightness(128);

  if (SD_init() == 0)
  {
    Serial.println("TF card initialized successfully");

  } else {
    Serial.println("TF card initialization failed");

  }

}

void loop(void)
{
	auto file = SD.open("/1.bmp");	
	lcd.drawBmp(&file, 100, 50);
}

This is the result:

Unfortunately i dont have access to 1.bmp right now. Ill upload it when possible

[TheRegularDX]

here is the original image. the 1.bmp is a converted version of this image

no need SPIClass SD_SPI;
you can use SPI instance

[lovyan03]

Do the following

  SPI.begin(SD_SCK, SD_MISO, SD_MOSI);
  if (!SD.begin(SD_CS, SPI, 40000000))

thank you! noob mistake. now it works fine
