#IMAGETYPE BUFFEREDIMAGE JAVA CODE#
If your images are small, it might not be worth the extra code complexity, as you'll hardly notice the difference.Īnyway, you can do it like this: // Create input stream The BufferedImage subclass describes an Image with an accessible buffer of image data. If your images are large, you'll benefit quite a bit from doing it this way, over first loading into a byte type. In my case, I want to convert the image type to BufferedImage.TYPE_INT_ARGB.Ī slightly (ok, I admit, quite a bit) more verbose, but in most cases faster and more memory efficient way of doing the same, is to load the image directly into a TYPE_INT_ARGB image. Because I use these types in the rest of my game, I wonder if there is a way to 'convert' the loaded image from the type it was loaded as, to another. This.pixels = ((DataBufferInt) image.getRaster().getDataBuffer()).getData() Īs I understand this, the BufferedImage isn't of the type BufferedImage.TYPE_INT_RGB or BufferedImage.TYPE_INT_ARGB. a BufferedImage object that has a specified image type: BufferedImage(int width. In the code, the line which the error is on, is in the constructor and looks like this: // Get the pixel array from the BufferedImage DIGITAL IMAGE PROCESSING WITH JAVA GUI 11.1 CLASS BUFFEREDIMAGE The. function I, mapOrAlpha buffered2im( jImage, varargin ) BUFFERED2IM Convert a Java BufferedImage to a Matlab image I BUFFERED2IM(JIMAGE) converts. I'm trying to access the pixels in a BufferedImage which is loaded from a file using ImageIO.read(filePath), but I get this error: Exception in thread "Game" : cannot be cast to Īt .(Texture.java:29)Īt .loadTexture(Texture.java:40) 1 BufferedImage: getSource() 2 BufferedImage: setRGB(int startX, int startY, int w, int h, int rgbArray, int offset, int scansize) 3 BufferedImage.
