How to blend CGGradients together in PageViewController?
ios,objective-c,gradient,uipageviewcontroller
The problem is that with a UIPageViewController you are not in charge of the views and (even more important) you don't get to customize the transition animation, so you can't add anything at the join. Since you only have four views, I would suggest you abandon UIPageViewController entirely and use...
Generation of edge stop parameter according to self-snake model in MATLAB
image,matlab,image-processing,gradient,edge-detection
From your comments, you said you want to find the gradient of the overall image. I'm assuming you mean to compute one magnitude value for the entire image. One way to do it is perhaps to find the average magnitude value. That can be done by simply finding the overall...

CSS gradient on border
html,css,background,border,gradient
That is because the background will extend to the border edge by default. You can avoid this by using the background-clip property, by setting background-clip: padding-box;. Working Example: input { background: transparent; font-family:'Open Sans'; border: 1px solid rgba(255, 255, 255, 0.2); box-sizing: border-box; padding: 5px; color: rgb(164, 164, 164); }...

It seems you are plotting your data rather than making a legend. Anyway.. The problem is the mismatch between your data range and maxColorValue.

My Solution: After trying a couple of ways (drawing a rectangle with default color onto the bar etc) I figured out that I can modify the offset of GradientStop by code: color_UL.Offset = 2.0 - ul_val / 100; means I subtract the percentage that I want to display e.g. 30%...
CSS issue with background button [duplicate]
html,css,button,background,gradient
The issue is that you are using the background shorthand property so trying to apply a second background image merely overwrites the previous statement (the gradient). You can use comma separated background image statements like this. CSS .btn{ background-image: /* note bg image */ url(http://lorempixel.com/output/abstract-q-c-32-32-2.jpg), linear-gradient(to bottom, rgba(0,166,255,1) 0%,rgba(0,166,255,1) 50%,rgba(2,154,236,1)...

Dynamic multi-color gradient image
You found the problem yourself already, actually.. So let's work further on that: You can see that the gradient effect is lost, because the static 255 is replaced with dynamic value which is creating negative numbers and thus losing its effect. So, instead of decreasing with $i each time, you...

There is no direct operation for something like this. In certain special cases (ie. colorpicker) you can get away with two separate gradients. If you want arbitrary color per corner, you will have to perform it pixel-wise. In other words do linear interpolation on both x and y for each...

or just add left background: -webkit-linear-gradient(`left`, rgba(255, 255, 255, 0) 0%, rgba(255, 255, 255, 1) 100%); section { position: relative; } .fadeout { position: absolute; right: 0; bottom: 0; width: 100%; height: 50%; background: -webkit-linear-gradient(left, rgba(255, 255, 255, 0) 0%, rgba(255, 255, 255, 1) 100%); background-image: -moz-linear-gradient(left, rgba(255, 255, 255,...
CAGradientLayer with 4 Colors in 4 Different Corners
ios,swift,gradient,cagradientlayer
Thanks for @Martin R's suggestions, here is some code that creates a blend that seems to work pretty well. Since there are so many colors it gets pretty dark in the middle, but in the end gets the desired effect: let gradientColors: Array <AnyObject> = [topColor1.CGColor, UIColor.clearColor().CGColor] let gradientLocations: Array...
Radial Gradient Clippath
No, you have to use a <mask> if you want gradients, <clipPath> only considers the geometry of the shapes inside.

Reversing gradients with Compass
I don't know Compass, so I can help you with the Compass syntax, but the CSS should be div { width: 300px; height: 300px; border: solid 1px black; } .test { background: linear-gradient(180deg, #f1693c 0,#f1693c 80px,#f37744 81px,#f37744 122px,#f4824a 123px,#f4824a 163px,#f68d50 164px,#f68d50 50%) top center / 100% 50% no-repeat, linear-gradient(0deg, #f1693c...

PHP Imagick color gray-scale gradient
php,image,colors,gradient,imagick
There is the colorizeImage function which would do what you asked. function colorizeImage($imagePath, $color, $opacity) { $imagick = new \Imagick(realpath($imagePath)); //TBH - not sure if opacity is meant to be on the color or colorize call //neither seem to have much effect. $opacity = $opacity / 255.0; $opacityColor = new...
Assistance with Gradient Background

finding value of a point between measured points on a 2D plane
This is the same algorithm for interpolating the height of a point from a triangle. In your case you don't have z values for heights, but some other float value for each triangle vertex, but it's the same concept, still 3D points. Where you have 3D triangle points p, q,...
How can I create tilt shift alpha mask on the fly?
I created this gradient with the code below. linearGradient = new LinearGradient(0, 0, 0, h, new int[]{0xffffffff, 0xffffffff, 0x00ffffff, 0x00ffffff, 0xffffffff, 0xffffffff}, new float[]{0, 0.30f, 0.45f, 0.55f, 0.7f, 1.0f}, Shader.TileMode.CLAMP); ...
White lines in gradient.rect from R's plotrix package
I was able to reproduce the problem (although not that image) with this code: png();plot(x=seq(as.Date("1979-05-04"),as.Date("1990-11-28"),length=50), 1:50,type="n",axes=FALSE) # set up plot coords correctly plotrix::gradient.rect(as.Date("1979-05-04"),5, as.Date("1990-11-28"),6, col=plotrix::smoothColors("royalblue", 100.0,"white"), border=NA,gradient="x",nslices=121); dev.off() Then I saw three thin, white vertical bands. I looked at the RGB values and plotted their hexadecimal equivalents: plot(NA, xlim=c(1,110),ylim=c(0x4169E1, 0xFFFFFF)...
Creating a frame for a view with gradient in xml

The answer was indeed layered-list. The mistake was just not lowering the alpha on the endColor.

Continuous varying color in three adjacent rectangles
android,opengl-es-2.0,gradient
The interpolation you see by using varying color in the fragment shader is a linear interpolation of color components as such: R = R1 + (R2-R1)*scale G = G1 + (G2-G1)*scale B = B1 + (B2-B1)*scale A = A1 + (A2-A1)*scale In your case C1(0,0,1,1) and C2(1,0,0,1) is interpolated. The...
