antialiasing

问题 I am drawing ECG graphs using C# Graphics. I draw the curve using drawlines method. however line joints look broken. I tried all available options of smoothing mode and capstyle, none helps. here is sample graph1 and sample graph2 code is below: private void DrawCurve(Graphics g, cPoint[] data) { List<Point> ps = new List<Point>(); for (int i = 0; i < data.Length - 1; i++) { int x = data[i].x; int y = data[i].y; if (x > 0 && x < (Width)) { ps.Add(new Point(x, y)); } else if (x > Width) {

问题 I am trying to achieve a jagged text effect with HTML and CSS text. I am aware of the webkit-font-smoothing and font-smooth properties, but even with those set to "none" and "never", the text is still smoother than I would like. Are there other css properties, or other methods I can use to force the text to be more jagged / aliased? Only caveat is it needs to be actual HTML text, not images. 回答1: A lot of text-shadow can approximate such effect. The more you add the more you get the bad

问题 Why are there jagged edges on some of the texts and images in the app i am developping? I have tried to go through the frames, and i have not used a division to set a frame (so the 1.134234 is not an issue), and I have tried different antialiasing methods. Does anybody have an idea? See attached for an example. EDIT: The images become jagged, when downscaled. So either resize them to fit the size directly in the actual file, OR via code as suggested in other StackOverflow questions. Now

问题 Assume I have a square raster of given size, and I want to "draw" (render) a circle (or ellipse) of given radius (or major / minor axes) and center. One way of doing this in Python with NumPy is: import numpy as np def ellipse(box_size, semisizes, position=0.5, n_dim=2): shape = (box_size,) * n_dim if isinstance(semisizes, (int, float)): semisizes = (semisizes,) * n_dim position = ((box_size - 1) * position,) * n_dim grid = [slice(-x0, dim - x0) for x0, dim in zip(position, shape)] position =

问题 I want to remove the antialiasing from an image. This code will get the 4 major colors from an image, compare each pixel to the 4 major colors and assign the closest color. import numpy as np from PIL import Image image = Image.open('pattern_2.png') image_nd = np.array(image) image_colors = {} for row in image_nd: for pxl in row: pxl = tuple(pxl) if not image_colors.get(pxl): image_colors[pxl] = 1 else: image_colors[pxl] += 1 sorted_image_colors = sorted(image_colors, key=image_colors.get,

问题 I draw patterns which have detailed pixels and they often face with Moire effect. I am not good at shading and I am not sure if this problem will be solved by shaders. I have not found any basic, understandable and complete example of shaders. Most of the tutorial websites start a program from the middle omitting the header file includes! This is a MWE of my code. Is it possible to mitigate or remove the Moire effect from it? #include <cmath> #include <vector> #ifdef __APPLE__ #include <GLUT

问题 While testing the GUI of my JavaFX 8 application, I noticed that some labels are not displaying anti-aliased text. After some googling and struggling, I found out a very annoying thing that is happening. The anti-aliasing is being applied only on labels which font size is greater than 80px. Here is an example comparing JavaFX and Swing applications with AA applied: Sample code: https://gist.github.com/anonymous/be60bb89181376ff12aa Is there a way to force the AA in all font sizes? Does this
