bufferedimage

问题 I have a buffered image with the sizes of my frame: public BufferedImage img; public static int WIDTH = 800; public static int HEIGHT = 600; img=new BufferedImage(WIDTH, HEIGHT,BufferedImage.TYPE_INT_RGB); How can I draw it so I can see just a black image filling the frame? without using Canvas I want to use only the drawImage function from graphics without using the paint or paintComponent functions If it is possible, how can i assign an 1D array [WIDTH*HEIGHT] to that image? SIMPLY: I want

问题 I download and test JavaFaces as a java project in Windows. but i'am tring to use it in android framework , but BufferedImage is not available in android ! how can i make this project compatible with android ? here is FaceRec.java that contain errors about BufferedImage . public class FaceRec { private FaceBundle bundle; private double[][] weights; Handler fh; Logger logger = Logger.getLogger("facerecognition.javafaces.FaceRec"); public FaceRec() { try { fh = new FileHandler("facerec.log");

问题 How do I find out the order of color channels in a BufferedImage (different types including alpha channels)? I need to know the order of R, G, and B parameters for operations like LookupOp (order of byte[][] in ByteLookupTable(int, byte[][])) or RescaleOp(float[], float[], hints). Is there a generic way to find the order from a given BufferedImage? I thought it should be in the ColorModel but I can't find it. I have used code like if (t == BufferedImage.TYPE_INT_ARGB) but there must be better

问题 I've been trying for a while now to get a game working in Java, after much anguish over other peoples Sprite functions I made my own and don't understand why I can't erase it. I know it's changing the pixels of the background to display my archer sprite since it shows up but for whatever reason I can't change the pixels back to what they were before. Does anyone have an idea why that is or how I can fix it? Link to google doc with images: https://docs.google.com/document/d/1eU6faW1d7valq1yE

问题 I'm trying to load this spritesheet into an array of buffered image (each sprite into one BufferedImage) : I opened this file on photoshop. The width is 500 and the height is 666. So according to my calculation, I need to loop 64 times (8 rows and 8 columns) and for each sprite, its width is 500/8 (62.5) and its height is 666/8(83.25). Since getSubImage accepts only int parameters, I was forced to put the width as 62 and the height a 83 (and I think this is why it truncates my images). Here's

问题 i am trying to load an image to be used as a texture and i keep getting input==null errors; This is my code where i am trying to load the image and where most of the errors are pointing to. package com.mime.minefront.graphics; import java.awt.image.BufferedImage; import javax.imageio.ImageIO; public class Texture { public static Render floor = loadBitmap("/C:\\Users\\Danny\\Documents\\NetBeansProjects\\MyFirstgame\\src\\res\\textures\\floor.png"); public static Render loadBitmap(String

问题 I am trying to create a game where I have a background image and text on top of that in the form of JLabel s. How would I go about doing that? The main reason I'm doing this is so that I can have 2 different text areas with different font sizes. Using g.drawString() will only let you use 1 text size for the whole thing. Here is my code so far: package com.cgp.buildtown; import java.awt.Font; import java.awt.FontFormatException; import java.awt.Graphics; import java.awt.Graphics2D; import java

问题 I'm trying to read an Image type JPG/JPEG to BufferedImage , change RGB value of pixel (0,0) Image file : http://i.upanh.com/rcfutp but it didn't work correctly Here is what i've try Read image public BufferedImage readImage1(String path) { BufferedImage _image = null; BufferedImage copy = null; try { _image = ImageIO.read(new File(path)); copy = new BufferedImage(_image.getWidth(), _image.getHeight(), BufferedImage.TYPE_3BYTE_BGR); copy.getGraphics().drawImage(_image, 0, 0, null); } catch

问题 I have 100 BufferedImage object's in ArrayList , i want to show all of these images in a jsp. <% ArrayList<BufferedImage> list = GlobalData.getImageBufferArrayList(); %> </head> <body> <ul> <li><img alt="" src=""> </li>//image1 <li><img alt="" src=""> </li>//image2 <li><img alt="" src=""> </li>//image3 ... .. ... </ul> </body> I don't know what to put in src on these images Is it possible to put image data as src of image.(Just like we get image data from canvas in html) Or is their any
