Prevent bitmap too large to be uploaded into a texture android

Question

I need to display original image in full screen in gallery form. For thumb it will be work perfectly and when I try to display that image in full screen with original source

Answer 1

I found a way to do this without using any external libraries:

if (bitmap.getHeight() > GL10.GL_MAX_TEXTURE_SIZE) {

    // this is the case when the bitmap fails to load
    float aspect_ratio = ((float)bitmap.getHeight())/((float)bitmap.getWidth());
    Bitmap scaledBitmap = Bitmap.createBitmap(bitmap, 0, 0,
                    (int) ((GL10.GL_MAX_TEXTURE_SIZE*0.9)*aspect_ratio),
                    (int) (GL10.GL_MAX_TEXTURE_SIZE*0.9));
    imageView.setImageBitmap(scaledBitmap);
}
else{

    // for bitmaps with dimensions that lie within the limits, load the image normally
    if (Build.VERSION.SDK_INT >= 16) {
        BitmapDrawable ob = new BitmapDrawable(getResources(), bitmap);
        imageView.setBackground(ob);
    } else {
        imageView.setImageBitmap(bitmap);
    }
}

Basically, the maximum image dimensions are a system-imposed limit. The above approach will correctly resize bitmaps that exceed this limit. However, only a portion of the entire image will be loaded. To change the region displayed, you can alter the x and y parameters of the createBitmap() method.

This approach handles bitmaps of any size, including pictures taken with professional cameras.
