Homebrew Help Loading Image From SD Card [SPIDER]

[gudenau]

Hmm. Could you check to make sure you are creating splash.bin properly? Not sure what else could be causing garbage graphics.

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.FileOutputStream;
 
import javax.imageio.ImageIO;
 
 
public class SplashConvert {
    public static void main(String[] args) throws Throwable{
        System.out.println(args[0]);
        System.out.println(args[1]);
       
        BufferedImage image = ImageIO.read(new File(args[0]));
        FileOutputStream out = new FileOutputStream(new File(args[1]));
       
        int[] data = new int[image.getWidth() * image.getHeight()];
        image.getRGB(0, 0, image.getWidth(), image.getHeight(), data, 0, image.getWidth());
 
        byte[] buffer = new byte[data.length * 3];
       
        for(int i = 0; i < data.length; i++){
            buffer[i*3] = (byte) (data[i] & 0x000000FF);
            buffer[i*3+1] = (byte) ((data[i]>>8) & 0x000000FF);
            buffer[i*3+2] = (byte) ((data[i]>>16) & 0x000000FF);
        }
       
        out.write(buffer);
        out.close();
    }
}

Didn't someone say it is BGR? Why does it have getRGB?

Because that is how Java works.

Because that is how Java works.

Really? Interesting. So, it IS for sure converting to BGR, correct?

 

[shutterbug2000]

Just curious: what is the image supposed to look like?

The gradient from the first page.

change IFile_Read(file, read, buf, 0xE100); to IFile_Read(file, read, buf, 0x38400);

this causes a crash, i guess its just too much data to read in. we need to malloc memory so we dont overwrite stuff

I need to clean up after spider.
