imagecolortransparent is probably not what you want here if you’re merging images, as single-colour transparency is nasty. Instead, try it with a transparent fill mask like so: <?php $image = imagecreatetruecolor(100, 100); // Transparent Background imagealphablending($image, false); $transparency = imagecolorallocatealpha($image, 0, 0, 0, 127); imagefill($image, 0, 0, $transparency); imagesavealpha($image, true); // Drawing over $black = … 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);
This is pretty easy to do in Winforms. What you need is a sandwich of two forms. The bottom one should provide the transparent gradient background, the top one should draw the icons and handle mouse clicks. Some sample code: public partial class Form1 : Form { public Form1() { InitializeComponent(); this.TopMost = true; this.FormBorderStyle … Read more
You can use a hatch brush with a certain percentage, for example: using System.Drawing.Drawing2D; private void Form1_Paint(object sender, PaintEventArgs e) { var hb = new HatchBrush(HatchStyle.Percent50, this.TransparencyKey); e.Graphics.FillRectangle(hb,this.DisplayRectangle); }
Since JDK8u60 b14 transparency is enabled in 3D shapes. This is a quick test done with it: A cylinder with diffuse color Color.web(“#ffff0080”), is added on top of a box and two spheres. group.getChildren().addAll(sphere1, sphere2, box, cylinder); There’s no depth sort algorithm though, meaning that order of how 3D shapes are added to the scene … Read more
There is no way to sort the triangles in a perfect way. Look at the examples at end of the Transparency Sorting article on opengl.org wiki. @kos: Give a look at Order Independent Transparency with Dual Depth Peeling and Alpha to Coverage.
The following script creates a transparent GIF with a red circle drawn in the middle: from PIL import Image, ImageDraw img = Image.new(‘RGBA’, (100, 100), (255, 0, 0, 0)) draw = ImageDraw.Draw(img) draw.ellipse((25, 25, 75, 75), fill=(255, 0, 0)) img.save(‘test.gif’, ‘GIF’, transparency=0) and for PNG format: img.save(‘test.png’, ‘PNG’)
This is possible using a ttk.Style. The idea is to modify the layout of the Horizontal.TProgressbar style (do the same with Vertical.TProgressbar for a vertical progressbar) to add a label inside the bar: Usual Horizontal.TProgressbar layout: [(‘Horizontal.Progressbar.trough’, {‘children’: [(‘Horizontal.Progressbar.pbar’, {‘side’: ‘left’, ‘sticky’: ‘ns’})], ‘sticky’: ‘nswe’})] With an additional label: [(‘Horizontal.Progressbar.trough’, {‘children’: [(‘Horizontal.Progressbar.pbar’, {‘side’: ‘left’, ‘sticky’: … Read more
Note: There’s a Python 3/pillow fork of PIL version of this answer here. Update 4: Guess the previous update to my answer wasn’t the last one after all. Although converting it to use PIL exclusively was a major improvement, there were a couple of things that seemed like there ought to be better, less awkward, … Read more
Does it have to be dynamic? The only way to do that is with an image with transparency (GIF or, better, PNG). I’m not sure if this is what you want, but will explain it anyway. Situation: you have a non plain background that you want to bee seen through your text. Solution: no CSS … Read more
