hi
I've been trying to load a bmp picture to use it as a texture at my program I've used a IOstream Class to extend DataInputStream to read the pixels at the photo with this code "based on a texture loader code for c++ " :
//class Data members
public static int BMPtextures[];
public static int BMPtexCount = 30;
public static int currentTextureID = 0;
//loading methode
static int loadBMPTexture(int index, String fileName, GL gl)
{
try
{
IOStream wdis = new IOStream(fileName);
wdis.skipBytes(18);
int width = wdis.readIntW();
int height = wdis.readIntW();
wdis.skipBytes(28);
byte buf[] = new byte[wdis.available()];
wdis.read(buf);
wdis.close();
gl.glBindTexture(GL.GL_TEXTURE_2D, BMPtextures[index]);
gl.glTexImage2D(GL.GL_TEXTURE_2D, 0, 3, width, height, 0, GL.GL_BGR, GL.GL_UNSIGNED_BYTE, buf);
gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MAG_FILTER, GL.GL_LINEAR);
gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MIN_FILTER, GL.GL_LINEAR);
currentTextureID = index;
return currentTextureID;
}
catch (IOException ex)
{
// Utils.msgBox("File Error\n" + fileName, "Error", Utils.MSG_WARN);
return -1;
}
}
and IOStream code :
public class IOStream extends DataInputStream {
public IOStream(String file) throws FileNotFoundException {
super(new FileInputStream(file));
}
public short readShortW() throws IOException {
return (short)(readUnsignedByte() + readUnsignedByte() * 256);
}
public int readIntW() throws IOException {
return readShortW() + readShortW() * 256 * 256;
}
void read(Buffer[] buf) {
}
}
and the calling:
GTexture.loadBMPTexture(1,"/BasicJOGL/src/basicjogl/data/Font.bmp",gl);
after debugging I figured out that when it come to this line :
IOStream wdis = new IOStream(fileName);
an IOExeption occurred and it's a dispatchException .. what this impose to mean ?? and how can I solve it ?
by the way i tried to :
1- use \ and \ and / and //
2- change the path of the photo and take all the path from c:\ to the photoname.bmp
3- rename the photo using numbers like 1.bmp
but nothing seems to work :(
