Image resizing in Java
Image resizing to a ration of standard size (For Ex: 1024x800 to 800x600) public void resizeFile(File original, int width, int height){ int newWidth=0; int newHeight=0; BufferedImage bufferedImage = ImageIO.read(original); int orginalWidth=bufferedImage.getWidth(); int orginalHeight=bufferedImage.getHeight(); float ratioWidth= (float)orginalWidth/(float)width; float ratioHeight=(float)orginalHeight/(float)height; if(ratioWidth>ratioHeight){ newWidth=width; newHeight= Math.round(orginalHeight/ratioWidth); }else{ newWidth= Math.round(orginalWidth/ratioHeight); newHeight=height; } // Now use these new newWidth and newHeight to write resized file........ -------- ------- }
