You will get a versatile image with great quality, that you can send to anyone without taking too much time. I couldnt find any library or solution for this. Im trying to find a way to compress the png, to have a smaller size, without reducing the quality. This is not a solution for me, because the images are stored in the database as BLOBs and the website loads slower. Get a Graphics2D object from the BufferedImage object of the output image. If I upload a 200 kb image, after cropping and making it PNG it has 600 kb. Create a BufferedImage object for the output image with a desired width and height. All of these are also installed when you install java which probably explains the large image size. In Java, to resize (or scale) an image and save it, we can follow these steps: Create a BufferedImage object for the input image by calling the read () method of the ImageIO class. If you have a huge photo, we recommend resizing it to about 1900 by 1100 pixels, with JPG format and 90% quality. Java7 probably has a large number of dependencies that need to be installed for it to run that aren't installed on your base Ubuntu image. There are a number of Scaling Types, but the one you probably want is Center Crop. In Java, to resize (or scale) an image and save it, we can follow these steps: Create a BufferedImage object for the input image by calling the read () method of the ImageIO class. The easiest way to handle this is to set the ScaleType of the ImageView. So if you resize your image, decreasing its width and height to a half, your image would have about the same number of pixels as the screens that will display it, and you wouldn't be losing any quality or detail, even looking at your image in full screen mode. The Image is resized to match the most limiting dimension (width). Photos from modern cellphones and cameras usually have over 6 million pixels, while most cellphones, tablets, notebook or TV screens have only about 1.5 million pixels, which means you end up seeing a resized version of the image (you only use the full image if you print it). Reducing image size doesn't reduce image quality, although it may lose small details. Image quality will suffer as you increase compression and start losing more data.Īnother method is to resize your photo, decreasing the pixels it takes to store the image. One way is compressing the image, which reduces file size without having to resize it.
