问题 Is there a way to manipulate alpha of an image using alpha from another image? Suppose I have a Image and I want to alter its alpha starting opaque at left and totally transparent at right, currently I draw another image with LinearGradientBrush and set alpha of orginal image from second image by looping pixel by pixel, is there another way in Gdiplus, some image mask, or blending alpha of two images? Conclusion: it seems there is no way in GDI+ to blend two images, only way seems to be the

问题 Using the follow image.. ... I am applying this code to create a circle mask: import cv2 import numpy as np img = cv2.imread("car.png") height, width, depth = img.shape circle_img = np.zeros((height, width), np.uint8) mask = cv2.circle(circle_img, (int(width / 2), int(height / 2)), 90, 1, thickness=-1) masked_img = cv2.bitwise_and(img, img, mask=circle_img) cv2.imshow("masked", masked_img) cv2.waitKey(0) This is the output.. How can I find BGR values of the circle using OpenCV ? 回答1: You can

问题 I have raster of the following features: library(raster) library(rgeos) test <- raster(nrow=225, ncols=478, xmn=-15.8, xmx=32, ymn=-9.4, ymx=13.1) I want to mask in this raster the cells that are within a given distance of a point. I create the spatial points as followed: p2=readWKT("POINT(31.55 -1.05)") Then I create a spatial polygon object by adding a 0.5 buffer: p2_Buffered <- gBuffer(p2, width = 0.5) mask(test, mask=p2_Buffered,inverse=T) When I mask my raster given this spatial object,

问题 I have the following problem to solve with WebGL: Imagine a mesh in front of the camera. The mesh is not actually shaded but its "silhouette" as a whole is used to reveal a background image as some sort of mask or stencil if you will. So e.g. you would have an output image with a white background and a silhouette-shape filled with a texture/image being the background at that position. (The meshes I want to use are obviously more complex than a sphere) What is the best way to achieve such an

问题 I have the host computer with Ethernet adapter configured by this way: IP address 192.170.100.10, subnet mask 255.255.255.0. There is also hardware device which works like IP server, configured as: 192.170.100.20, 255.255.255.0. When I connect this device to the host Ethernet adapter, the following information is added to route print command output (Windows): Active Routes: Network Destination Netmask Gateway Interface Metric 192.170.100.0 255.255.255.0 192.170.100.10 192.170.100.10 20 192

问题 when the contents are loaded with ajax, the mask is not working on the input text. What Should I do? with thanks Code: $.ajax({url: path, data: {action:'create_form_profile'}, timeout:5000, type:"POST", success: function(data) { $("#_content").html(data); { $("#birth_date").mask("9999/99/99"); } $("input:hidden").click(function(event) { window.location.href = "logout.php"; sho‌​w_exit(); }); } }); 回答1: For me works this in ajax callback: $('.phone').unmask().mask(phoneMask); I don't

问题 In my example below, the mask works as it should on the green and blue lines, but makes the horizontal red line disappear altogether. When the mask is removed, the red line seems to have nothing wrong with it. What's going on? document.querySelector('button').addEventListener('click', function(){ document.getElementById('problem-line').removeAttribute('mask') }, false) <svg width="400" height="180"> <defs> <g id='circle'> <circle r="50" cx="100" cy="100" /> </g> <mask id="hole"> <rect width=

问题 Please someone can explain to me the purpose of the source and dest parameters in android.text.InputFilter#filter? I tried to read the docs but I am really confused. I am trying to use a regex to make an IP mask. Any help is appreciated. I get it now. So, for example, if I have 123.42, then the user types 123.42d, I will have: dest = 123.42 source = 123.42d start = 5 end = 6 InputFilter[] filters = new InputFilter[1]; filters[0] = new InputFilter() { public CharSequence filter(CharSequence

问题 I've been having trouble to make a JFormattedTextField to use dates with the format dd/MM/yyyy. Specifically, as the user types, the cursor should "jump" the slashes, and get directly to the next number position. Also, the JFormattedTextField must verify if the date entered is valid, and reject it somehow if the date is invalid, or "correct it" to a valid date, such as if the user input "13" as month, set it as "01" and add +1 to the year. I tried using a mask ("##/##/####") with the validate
