image-scaling

I'm creating an universal app. For one screen, I'm displaying 6 images (png format) in a grid using this control. Also this screen supports both portrait and landscape orientation. I've created a set of images in different resolutions for all the iDevices and named them using the correct naming convention as follows. name~iphone.png name@2x~iphone.png name~ipad.png name@2x~ipad.png name-568h@2x~iphone.png (iPhone 5) And I had to create another set of these images since I support both orientation and I can't use the same images as above because in landscape it would stretch. Now I have close to

For my question I have prepared a very simple test app at Github. For simplicity I have removed flinging, scroll constraints and edge effects (which actually work well in my real app): So the custom view in my test app only supports scrolling: mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() { @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float dX, float dY) { mBoardScrollX -= dX; mBoardScrollY -= dY; ViewCompat.postInvalidateOnAnimation(MyView.this); return true; } }); and pinch zooming with 2 fingers (the focus is broken though

I have a directory full of images that I would like to resize to around 60% of their original size. How would I go about doing this? Can be in either Python or Perl Cheers Eef How about using mogrify, part of ImageMagick ? If you really need to control this from Perl, then you could use Image::Magick , Image::Resize or Imager . Anurag Uniyal If you want to do it programatically, which I assume is the case, use PIL to resize e.g. newIm = im.resize((newW, newH) then save it to same file or a new location. Go through the folder recursively and apply resize function to all images. I have come up

i got a problem with image scaling in C#. I have a picture Box with given Size : e.g. width = 800px height = 600px I am loading different images into that picture box, small ones ( 400x400) and big ones (800+ x 600+) My images are getting resized if they do not fit into box. But they are always resized to MAX width and height of PictureBox. So the aspect ratio is destroyed . Can anybody help to identify / fix the problem? Classes: Form1.cs ImageHandling.cs (commented out) ImageUtilities.cs Examples: Problem 1: My Version vs Original Source Problem 2: My Version vs Original Source How i want it

Does anyone have the secret formula to resizing transparent images (mainly GIFs) without ANY quality loss - what so ever? I've tried a bunch of stuff, the closest I get is not good enough. Take a look at my main image: http://www.thewallcompany.dk/test/main.gif And then the scaled image: http://www.thewallcompany.dk/test/ScaledImage.gif //Internal resize for indexed colored images void IndexedRezise(int xSize, int ySize) { BitmapData sourceData; BitmapData targetData; AdjustSizes(ref xSize, ref ySize); scaledBitmap = new Bitmap(xSize, ySize, bitmap.PixelFormat); scaledBitmap.Palette = bitmap

BACKGROUND:- I am required to make a Swing GUI using Netbeans GUI Builder. The first sub-task is to display an image in the entire background. I have followed a tutorial to get that done. I have basically made a JFrame, set its layout to GridBagLayout and then added a transparent (by unchecking the opaque property) JPanel to it. (Question 1) After that I added a JLabel to the JFrame, Removed its text and added an image to it. (Question 2) QUESTIONS:- First, when I add the JPanel, it does not show its resize handles. I Googled a bit and found this tutorial , in which it can be seen that when
