Seeing as you have a Canvas to work with. Here is one option. private Bitmap makeRadGrad() { RadialGradient gradient = new RadialGradient(200, 200, 200, 0xFFFFFFFF, 0xFF000000, android.graphics.Shader.TileMode.CLAMP); Paint p = new Paint(); p.setDither(true); p.setShader(gradient); Bitmap bitmap = Bitmap.createBitmap(400, 400, Config.ARGB_8888); Canvas c = new Canvas(bitmap); c.drawCircle(200, 200, 200, p); return bitmap; } Result:
With z-index : You may use a container and put the gradient on that container. Then use a negative z-index to position image behind the gradient. .pickgradient { display:inline-block; background: -moz-linear-gradient(top, rgba(0,0,0,0) 0%, rgba(0,0,0,0.65) 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,0,0,0.65)), color-stop(100%,rgba(0,0,0,0))); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* … Read more
Keep in mind that a CSS gradient is actually an image value, not a color value as some might expect. Therefore, it corresponds to background-image specifically, and not background-color, or the entire background shorthand. Essentially, what you’re really trying to do is layering two background images: a bitmap image over a gradient. To do this, … Read more
You can use ShaderMask for that task. In ShaderMask, you need to set the BlendMode to BlendMode.srcIn, “src” means the widget to apply the gradient to (in this case Text), “in” means only show the part of the Text where it overlaps with the background which is the text itself (so the gradient doesn’t get … Read more
You just need to create a drawable resource (see an example below), and add it to the layout you created for your ListItem. The drawable (in your res\drawable folder – name it whatever – listgrad.xml for ex) could look like: <shape xmlns:android=”http://schemas.android.com/apk/res/android” android:shape=”rectangle”> <gradient android:startColor=”@color/gradient_start” android:endColor=”@color/gradient_end” android:angle=”-270″ /> </shape> The you would add it to … Read more
If you get deltaX and deltaY from your coordinates then Math.atan2 returns the arctangent of the quotient of its arguments. The return value is in radians. var deltaX = x2 – x1; var deltaY = y2 – y1; var rad = Math.atan2(deltaY, deltaX); // In radians Then you can convert it to degrees as easy … Read more
Note that if you have many points, calling plt.plot for each line segment can be quite slow. It’s more efficient to use a LineCollection object. Using the colorline recipe you could do the following: import matplotlib.pyplot as plt import numpy as np import matplotlib.collections as mcoll import matplotlib.path as mpath def colorline( x, y, z=None, … Read more
You simply linearly interpolate the red, the green, and the blue channels like this: double resultRed = color1.red + percent * (color2.red – color1.red); double resultGreen = color1.green + percent * (color2.green – color1.green); double resultBlue = color1.blue + percent * (color2.blue – color1.blue); where percent is a value between 0 and 1 (location in … Read more
If you wish to do this using CSS3 gradients, try using the background-attachment property For example, if you are applying your gradients to #background, then add this after the CSS gradient. background-attachment: fixed; Note: You must add background-attachment after the background properties. Your entire code might look like this: #background { background: #1e5799; background: -webkit-gradient(linear, … Read more
