Save screen directly to Jpg > code
May 27th, 2005, 11:17am  
Hey, got a bit tired of converting the tif-files to jpg before sending them to friends, so .. i just wrote this little function:

Code:

import com.sun.image.codec.jpeg.*;

void SaveJpg(String fname){
  ByteArrayOutputStream out = new ByteArrayOutputStream();
  BufferedImage img = new BufferedImage(width, height, 2);
  img = (BufferedImage)createImage(width, height);
  loadPixels();
  for(int i = 0; i < width; i++)
  {
    for(int j = 0; j < height; j++)
    {
	int id = j*width+i;
	img.setRGB(i,j, pixels[id]); 
    }
  }
  try{
    JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
    encoder.encode(img);
  }
  catch(FileNotFoundException e){
    System.out.println(e);
  }
  catch(IOException ioe){
    System.out.println(ioe);
  }
    byte [] a = out.toByteArray();
  saveBytes(fname,a);
}



Enjoy

No problem Smiley
add this after JPEGImageEncoder, for qualitysettings..
Code:

JPEGEncodeParam encpar = encoder.getDefaultJPEGEncodeParam(img);
encpar.setQuality(1,true); // 0.0-1.0, force baseline (?)


---EDIT---
AND change encoder.encode(img); to encoder.encode(img,encpar);

You might wanna check this thread from the Processing ALPHA board full of 'ancient thoughts and moldy code' Wink

wow.. was a lot of cool stuff in there.. to bad all the code-links were gone.. only some posted stuff, and that didn't seem like the final product..

but still, thanks for pointing me there, got a lot of pointers on how to further develop my function:)

If you're looking for some specific code-links, I might have some of the old code back in my moldy 0048-0065 folders.
