I'm trying to get the pixels in RGB format of an image. I have the following code:
public void writeColorImageValueToFile(BufferedImage in, String fileName)
{
int width = in.getWidth();
int height = in.getHeight();
try
{
FileWriter fstream = new FileWriter(fileName + ".txt");
BufferedWriter out = new BufferedWriter(fstream);
int [] data = new int[width * height];
in.getRGB(0, 0, width, height, data, 0, width);
for(int i = 0; i < (height * width); i++)
{
out.write(((data[i] >> 16) & 0xff) + ", ");
out.write(((data[i] >> 8) & 0xff) + ", ");
out.write((data[i] & 0xff) + "\n");
}
out.close();
} catch (Exception e)
{
System.err.println("Error: " + e.getMessage());
}
}
I created an image in photoshop and I filled it with the color RGB(86, 136, 152), however I got from my java method the value of RGB(44, 139, 154).
I load the image using:
BufferedImage img = ImageIO.read(new File("blue.jpg"))
I don't know what I'm doing wrong.
Any suggestion?
尝试将图像保存为PNG格式,然后重试!
