Examples with Display android.view.Display used on opensource projects

Example 6 with Display

use of android.view.Display in project OpenPanodroid by duerrfk.

the class PanoViewerActivity method convertCubicPano.

private void convertCubicPano() {
    Assert.assertTrue(pano != null);
    Log.i(LOG_TAG, "Converting panorama ...");
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
    String str = prefs.getString("textureSize", "");
    int maxTextureSize = GlobalConstants.DEFAULT_MAX_TEXTURE_SIZE;
    if (!str.equals("")) {
        try {
            maxTextureSize = Integer.parseInt(str);
        } catch (NumberFormatException ex) {
            maxTextureSize = GlobalConstants.DEFAULT_MAX_TEXTURE_SIZE;
        }
    }
    // On the one hand, we don't want to waste memory for textures whose resolution 
    // is too large for the device. On the other hand, we want to have a resolution
    // that is high enough to give us good quality on any device. However, we don't
    // know the resolution of the GLView a priori, and it could be resized later.
    // Therefore, we use the display size to calculate the optimal texture size.
    Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
    int width = display.getWidth();
    int height = display.getHeight();
    int maxDisplaySize = width > height ? width : height;
    int optimalTextureSize = getOptimalFaceSize(maxDisplaySize, pano.getWidth(), GlobalConstants.DEFAULT_FOV_DEG);
    int textureSize = toPowerOfTwo(optimalTextureSize);
    textureSize = textureSize <= maxTextureSize ? textureSize : maxTextureSize;
    Log.i(LOG_TAG, "Texture size: " + textureSize + " (optimal size was " + optimalTextureSize + ")");
    panoConversionTask = new PanoConversionTask(textureSize);
