I made a slight modification to the OP code and got the transparency working. It appears that the facecolors argument of Poly3DCollection overrides the transparency argument, so the solution was to set the color in a separate call to either Poly3DCollection.set_color or Poly3DCollection.set_facecolor: from matplotlib import pyplot as plt from mpl_toolkits.mplot3d.art3d import Poly3DCollection fig = … Read more
After you clear the background with the CLEAR composite, you need to set it back to SRC_OVER to draw normally again. ex: //clear g2.setComposite(AlphaComposite.getInstance(AlphaComposite.CLEAR)); g2.fillRect(0,0,256,256); //reset composite g2.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER)); //draw g2.setPaint(Color.RED); g2.fillOval(50,50,100,100);
From this answer [self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault]; self.navigationController.navigationBar.shadowImage = [UIImage new]; self.navigationController.navigationBar.translucent = YES; self.navigationController.view.backgroundColor = [UIColor clearColor]; self.navigationController.navigationBar.backgroundColor = [UIColor clearColor]; Also, as suggested by Josh in the comments, to put the bar back to default: [self.navigationController.navigationBar setBackgroundImage:nil forBarMetrics:UIBarMetricsDefault];

Basically, you need to make a transparent window and a translucent content pane. This will mean anything added to the content pane will continue to be rendered without additional alphering… public class TranscluentWindow { public static void main(String[] args) { new TranscluentWindow(); } public TranscluentWindow() { EventQueue.invokeLater(new Runnable() { @Override public void run() { try … Read more
Here’s an example (the PNG file example.png has lots of transparency in different places): from Tkinter import Tk, Frame, Canvas import ImageTk t = Tk() t.title(“Transparency”) frame = Frame(t) frame.pack() canvas = Canvas(frame, bg=”black”, width=500, height=500) canvas.pack() photoimage = ImageTk.PhotoImage(file=”example.png”) canvas.create_image(150, 150, image=photoimage) t.mainloop() You need to make sure the image has been stored as … Read more
You can use transparent image to simulate the result. Use Pillow to create transparent image and then use canvas.create_image(…) to draw it. Below is a sample code: from tkinter import * from PIL import Image, ImageTk root = Tk() images = [] # to hold the newly created image def create_rectangle(x1, y1, x2, y2, **kwargs): … Read more
For Java 6 (and 5 too, I think): BufferedImage bufferedImage = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_INT_RGB); g = bufferedImage.createGraphics(); //Color.WHITE estes the background to white. You can use any other color g.drawImage(image, 0, 0, bufferedImage.getWidth(), bufferedImage.getHeight(), Color.WHITE, null);
Set imagealphablending($image,true); on each new layer. Try this: <?php $image = imagecreatetruecolor(485, 500); imagealphablending($image, false); $col=imagecolorallocatealpha($image,255,255,255,127); imagefilledrectangle($image,0,0,485, 500,$col); imagealphablending($image,true); /* add door glass */ $img_doorGlass = imagecreatefrompng(“glass/$doorStyle/$doorGlass.png”); imagecopyresampled($image, $img_doorGlass, 106, 15, 0, 0, 185, 450, 185, 450); imagealphablending($image,true); /* add door */ $img_doorStyle = imagecreatefrompng(“door/$doorStyle/$doorStyle”.”_”.”$doorColor.png”); imagecopyresampled($image, $img_doorStyle, 106, 15, 0, 0, 185, 450, 185, 450); … Read more
