First of all, there is honestly no valid reason to use spacer GIFs in 2020 and beyond (unless you’re working with retro style websites), so this post is mostly just for the curious. Anyway let’s begin: The smallest valid transparent GIF is 35 bytes. data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEAAAAALAAAAAABAAEAAAIBAAA= 47 49 46 38 39 61 01 00 01 00 …
You can achieve a transparent cut out circle with 2 different techniques : 1.SVG The following examples use an inline svg. The first snippet uses the mask element to cut out the transparent circle and the second hollow circle is made with a path element. The circle is made with 2 arc commands : With …
You can use “transparent” as a colour. In some versions of IE, that comes up as black, but I’ve not tested it out since the IE6 days. http://www.researchkitchen.de/blog/archives/css-bordercolor-transparent.php
Try this: ImageView myImage = (ImageView) findViewById(R.id.myImage); myImage.setAlpha(127); //value: [0-255]. Where 0 is fully transparent and 255 is fully opaque. Note: setAlpha(int) is deprecated in favor of setAlpha(float) where 0 is fully transparent and 1 is fully opaque. Use it like: myImage.setAlpha(0.5f)
In Photoshop’s Info panel, you can choose ‘Opacity’ as a readout mode, though it will show up as a percentage and not as a real alpha value. To enable it, simply open the Info window, choose Panel Options and then set the Second Color Readout mode to Opacity.
Instead of setting the opacity of the window, set its background’s opacity: <Window x:Class=”WpfApplication3.MainWindow” xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml” Title=”MainWindow” Height=”350″ Width=”525″ AllowsTransparency=”True” WindowStyle=”None”> <Window.Background> <SolidColorBrush Opacity=”0.5″ Color=”White”/> </Window.Background> <Grid> <Button Width=”200″ Height=”50″>button</Button> </Grid> </Window>
Just use an 8-digit color value, e.g. #FFF8F8F6, where the first two characters are the alpha value. FF being fully opaque, and 00 being fully transparent.
For a fully transparent plot, make sure to specify both the paper bgcolor and the plot’s: import plotly.plotly as py from plotly.graph_objs import * py.sign_in(”, ”) data = Data([ Bar( x=[‘Sivaranjani S’, ‘Vijayalakshmi C’, ‘Rajeshwari S’, ‘Shanthi Priscilla’, ‘Pandiyaraj G’, ‘Kamatchi S’, ‘MohanaPriya’, ‘Madhumitha G’, ‘Franklin Alphones Raj J’, ‘Akfaris Almaas’, ‘Biswajit Champati’, ‘Priya R’, …
Just create a new BufferedImage with transparency, then paint the other two images (with full or semi-transparency) on it. This is how it will look like: Sample code (images are called ‘image.png’ and ‘overlay.png’): File path = … // base path of the images // load source images BufferedImage image = ImageIO.read(new File(path, “image.png”)); BufferedImage …
