I don’t know why zorder has that behavior and it’s likely that might be a bug or, at the very least, a badly documented feature. It might be because there are already automatic references to zorder when you build a plot (like grid, axis, and so on…) and when you try to specify the zorder … Read more
As it turned out in comments, the layers in question are what iText indeed calls layers but what actually in PDF lingo is called optional content groups. There indeed is a utility class for removing such layers in the iText Xtra package (not the extrajars, but itext-xtra.jar): com.itextpdf.text.pdf.ocg.OCGRemover which makes use of the class OCGParser … Read more
You can lock the bitmap data and use pointers to manually set the values. It’s much faster. Though you’ll have to use unsafe code. public override void PaintPoint(Layer layer, Point position) { // Rasterise the pencil tool // Assume it is square // Check the pixel to be set is witin the bounds of the … Read more

this is a class that displays an image with additional layers: import java.util.ArrayList; import java.util.Iterator; import android.content.Context; import android.content.res.Resources; import android.content.res.TypedArray; import android.graphics.Bitmap; import android.graphics.Canvas; import android.graphics.Matrix; import android.graphics.Rect; import android.graphics.drawable.BitmapDrawable; import android.graphics.drawable.Drawable; import android.net.Uri; import android.util.AttributeSet; import android.util.DisplayMetrics; import android.util.Log; import android.util.TypedValue; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.view.animation.Transformation; import android.widget.ImageView; public class LayeredImageView extends … Read more
No, however, you could layer multiple <canvas> elements on top of each other and accomplish something similar. <div style=”position: relative;”> <canvas id=”layer1″ width=”100″ height=”100″ style=”position: absolute; left: 0; top: 0; z-index: 0;”></canvas> <canvas id=”layer2″ width=”100″ height=”100″ style=”position: absolute; left: 0; top: 0; z-index: 1;”></canvas> </div> Draw your first layer on the layer1 canvas, and the … Read more
Try this #import <QuartzCore/QuartzCore.h> // not necessary for 10 years now 🙂 … view.layer.cornerRadius = 5; view.layer.masksToBounds = true; Note: If you are trying to apply rounded corners to a UIViewController‘s view, it should not be applied in the view controller’s constructor, but rather in -viewDidLoad, after view is actually instantiated.
Yes, you CAN do this. Using pointer-events: none along with CSS conditional statements for IE11 (does not work in IE10 or below), you can get a cross browser compatible solution for this problem. Using AlphaImageLoader, you can even put transparent .PNG/.GIFs in the overlay div and have clicks flow through to elements underneath. CSS: pointer-events: … Read more
