How to make a color gradient in a SeekBar?

阅读更多关于 How to make a color gradient in a SeekBar?

I want to use a SeekBar (i.e. old school Java Slider) into a color gradient picker. I have seen some examples like this but they all require making new classes and such. There has got to be a way to modify or override the original classes. Or just replace the background with a gradient. JPM I figured it out here is how you do it. You create a standard seekbar in your XML. <SeekBar android:id="@+id/seekbar_font" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="10px" android:layout_below="@id/color_font_text" android:max="100" android:progress="50"><

Pure CSS3 text color gradient - Is it possible?

阅读更多关于 Pure CSS3 text color gradient - Is it possible?

Is there a way to create a cross-browser, pure CSS3 text color gradient? So, no png's. No 'webkit' only. EDIT: To be more precise: It's CSS3 only, and it's for text, not box gradients. EDIT: I found this solution , but it's only for webkit. There is no cross-browser way to do this outside webkit because only webkit currently has a background-clip: text , and this extension to background-clip is not on standards track (as far as I am aware). If you want to relax your CSS3 requirement, you can accomplish the same effect cross-browser with Canvas (or SVG), but then you're talking about HTML5

Line rasterisation: Cover all pixels, regardless of line gradient?

阅读更多关于 Line rasterisation: Cover all pixels, regardless of line gradient?

问题 Basically, I want to use a line algo to determine which cells to check for collisions for my raycaster. Bresenham isn't great for this as it uses a unified-thickness approach, meaning that it ignores cells that aren't at least half-covering the line. Not great at all, because it means that some segments of my line aren't being checked for intersections with the cells, leading to errors. I can't seem to find any "thick-line" algorithms, can anyone help me find one? Green: What I would like.

问题 I would like for my page to have a gradient background flowing from top to bottom. I want the background to act like a fixed image in that the gradient stretches from the top of the current browser viewport to the bottom and looks the same as you scroll up and down the page. In other words, it does not repeat when you scroll. It stays fixed in place. So what I want is this: and after scrolling to the bottom you see this Notice that the gradient looks exactly the same on the bottom of the page

问题 I have a white image that I'd like to color with a gradient. Instead of generating a bunch of images each colored with a specific gradient, I'd like to do this in code (not xml). To change an image's color, I use imageView.setColorFilter(Color.GREEN); And this works fine. But how can I apply a gradient color instead of a solid color? LinearGradient doesn't help, because setColorFilter can't be applied to Shader objects. EDIT : This is the image I have: This is what I want: And this is what I
