问题 I am loading an image using a Loader. Once loaded, I can get the bitmap data using Bitmap(event.target.loader.content).bitmapData . However since the images I am loading are quite large (around 2000 x 1600), I would like to reduce the size and create a new smaller bitmap maybe 200 or 300 pixels wide, sort of like a thumbnail. I think it has to do with creating a new BitmapData with the new size. However I am not able to get that working properly. Any ideas? 回答1: Not tested, but this should

问题 I want to create Web pages that allow users to drag and drop images into boxes in various parts of the page, so that they can then print the pages with their images. I want the image to automatically resize when it's dropped in the box. I combined some of the code at http://html5demos.com/file-api with some of the code at http://html5demos.com/file-api-simple to get something like I want. In the current version of the code (below), the image width does not resize the first time you drop the

问题 I'm currently coding an uploader script based on Uploadify. Right now I resize the given image and watermark one of the sizes. It all works well, but I need the script to resize the height and then crop the width so that the aspect ratio does not get messed up. This is my code so far: if ($fileExtension == "jpg" || $fileExtension == "jpeg" || $fileExtension == "png" || $fileExtension == "gif"){ // GD variables: list($width, $height, $type) = GetImageSize($uploadedFile['tmp_name']); // Image

问题 I have a WPF window with expandable panel (via Expander ). The panel is on the left side of the window, and when expanded the window grows to fit the content. By default, windows are anchored to the top-left, so my window grows to the right. I'd like the window to grow to the left. I tried to do the following in the Window.SizeChanged event: private void onWindowSizeChanged(object sender, SizeChangedEventArgs e) { Left -= (e.NewSize.Width - e.PreviousSize.Width) } and it works, but the growth

问题 So I need to procedurally generate a background image for a grid, it only takes .1sec. So I can wire into the SizeChanged event, but then when you resize the chart, it goes and fires the even maybe 30 times a second, so the resize event lags out signifigantly. Does anybody know a good way to wire into the resize event and test weather the use is done resizing, I tried simply checking for the mouse up/down state, but when the resize event fires the mouse is pretty much always down. 回答1: On

问题 I am working with SWT and I would like to be able to resize a composite by dragging the corner of it, the same way that you can resize a shell. I'm sure someone out there has implemented a good solution. Thanks. 回答1: I think what you are looking for can be implemented with org.eclipse.swt.widgets.Tracker here is sample working code: public static void main(String[] args) { Display display = new Display(); final Shell shell = new Shell(display); shell.open(); final Composite b = new Composite

问题 I embed .mov clips that sometimes are bigger than the place where I show it, so I want to resize the clip. Have tried with width and height but that only changes the area to display it; it does not resize the actual movie. Is it possible to resize the movie size? If yes, how? 回答1: Yes, you need the scale attribute: <embed src="sample.mov" width="200" height="240" scale="tofit"> There's a full reference for QuickTime video attributes here. 回答2: Sometimes the scale attribute doesn't work.
