image-scaling

问题 Important note : I'm using PyGObject to get access to the GTK widgets, not PyGTK . That's what makes this question different from similar ones: PyGTK: How do I make an image automatically scale to fit it's parent widget? Scale an image in GTK I want to make a very simple app that displays a label, an image and a button, all stacked on top of each other. The app should be running in fullscreen mode. When I attempted it, I've run into a problem. My image is of very high resolution, so when I

问题 I'm currently working on a project which requires me to read images and enlarge them. I'm currently using the nearest neighbour algorithm to enlarge my image, but i'm trying to use bilinear interpolation and finding it hard to implement. Here is my current NN algorithm: public void doThumbnailResize() { resizedImage = new BufferedImage(55, 55, BufferedImage.TYPE_3BYTE_BGR); int h = resizedImage.getHeight(), h2 = image1.getHeight(); int w = resizedImage.getWidth(), w2 = image1.getWidth(); for

问题 I am starting an Access database with exam questions. Almost every question will have a picture attached to it. I would prefer not to save the pictures in the database to keep it small. I want to insert these pictures in a report. The pictures must all have the same width (the width of the report), but the height must be resized according to the original aspect ratio. Some pictures are landscape and others portrait. I have now spent three days trawling the internet and still can not find a

问题 I have some old Java 2D code I want to reuse, but was wondering, is this the best way to get the highest quality images? public static BufferedImage getScaled(BufferedImage imgSrc, Dimension dim) { // This code ensures that all the pixels in the image are loaded. Image scaled = imgSrc.getScaledInstance( dim.width, dim.height, Image.SCALE_SMOOTH); // This code ensures that all the pixels in the image are loaded. Image temp = new ImageIcon(scaled).getImage(); // Create the buffered image.
