Hi julio
i use this routine to redimensione my images
public static BufferedImage redimensionarImagem(BufferedImage img, int
maltura, int mlargura) throws Exception {
java.awt.Image imagem = (java.awt.Image) img;
java.awt.Image thumbs = ((java.awt.Image) imagem)
.getScaledInstance(mlargura, maltura, BufferedImage.SCALE_SMOOTH);
BufferedImage buffer = new BufferedImage(mlargura, maltura,
BufferedImage.TYPE_INT_RGB);
buffer.createGraphics().drawImage(thumbs, 0, 0, null);
return buffer;
}
pass the width and height in pixels (maltura e mlargura)
After thar you can upload the image.
cheers
Claudio
