image-manipulation

I am making a basic Tiff viewer and need to be able to select the page to be viewed. In Winforms I could use selectActiveFrame, so I was wondering if there is a WPF equivalent for this. Thanks! EDIT: In winforms I used System.Drawing.Imaging.FrameDimension in the selectActiveFrame method if that helps at all. You can use the TiffBitmapDecoder class to load the image and then use the Frames property to access which tiff frame you like. 来源： https://stackoverflow.com/questions/4546994/simple-wpf-page-selection-for-multipaged-tiff

Here's a rough sketch of what I'm talking about: My question is, how can I rotate an image in 3D space? The approach I think I'd like to take, is to cut off a portion of the top and side of the image, and rotate then in 3D and then stich it

Good Day Everyone I was hoping if you could help me understand the concepts of understanding how to add an image into a canvas on a OnTouchEvent implemented on a View. So far, this is what i've come up with. parent is the Activity where in this customized view is instantiated and is added into. @Override protected void onDraw(Canvas canvas) { // TODO Auto-generated method stub super.onDraw(canvas); } public void insertImage() { if (parent.selected_icon.contentEquals("image1")) { image = getResources().getDrawable(R.drawable.image1); } else if (parent.selected_icon.contentEquals("image1")) {
