I want to create a web application that allow users to upload their image to the server. When they click send, their image will be uploaded to the server (multipart). Before saving, I want to make some operation with the image, so I decided to use .. ImageIO.read(InputStream) to get BufferedImage object here is the code: public static BufferedImage getBufferedImageFromMultipartFile(MultipartFile file) throws APIException { BufferedImage bi = null; try { bi = ImageIO.read(file.getInputStream()); } catch (IOException e) { throw new APIException(ErrorCode.SERVER_ERROR, e); } return bi; } The

I've found that I'm getting different RGB when using Java (& actually paint.NET ) than I am using ImageMagick, Gimp, Python, and Octave. The last 4 all agreeing with eachother and so I'm assuming to be correct. For these examples, I'm using this test image: http://farm3.static.flickr.com/2811/9177301733_9836174725_o.jpg Testing pixel x=4144 y=2768 R G B Java = (125, 107, 69) Paint.NET = (125, 107, 69) ImageMagick = (128, 106, 67) Python = (128, 106, 67) Octave = (128, 106, 67) Gimp = (128, 106, 67) What gives? Here's a quick test using imagemagick: convert image.jpg -crop 1x1+4144+2768 -depth

I am creating an application which is a kind of gallery - it shows different media content as a fullscreen viewer. Allocations instrument shows that Live Bytes parameter doesn't grow higher than 40 Mb when using application. Meanwhile the app is 100% being killed after I slide pages 20-30 times. I checked Dirty Memory parameter and found it was 10 times bigger than Live Bytes size. And the most of that dirty memory consumed Image IO: EDIT, another screenshot: The allocations peaks above are switching video/image media contents. The problem is the dirty memory grows almost linearly and I need

Consider I have a sample JavaFX application which updates its UI with an image read from the application's JAR, and does so in a delayed manner (i.e. the image is painted after the UI is shown): import javafx.application.Application; import javafx.application.Platform; import javafx.embed.swing.SwingFXUtils; import javafx.scene.Node; import javafx.scene.Scene; import javafx.scene.control.Label; import javafx.scene.image.ImageView; import javafx.scene.layout.StackPane; import javafx.stage.Stage; import javax.imageio.ImageIO; import java.awt.image.BufferedImage; import java.io
