问题 I have been trying to figure out what I am doing wrong when calculation the position and size of the mask rectangle once the target image has been resized. Below is the documentation from fabric JS: clipPath :fabric.Object a fabricObject that, without stroke define a clipping area with their shape. filled in black the clipPath object gets used when the object has rendered, and the context is placed in the center of the object cacheCanvas. If you want 0,0 of a clipPath to align with an object

问题 I am trying to get my game to look/scale well across different devices. I am attempting to introduce the dp and sp metrics into my apps as much as possible, but in this case I am refactoring a game to use these metrics for layout and widget sizing. Where before, my layouts were sized using size_hint in order to have everything get it's size relative to it's parent(the app itself is not given a size, nor is the window, but the root widget/layout has size_hint=(1, 1) ), I am now faced with

问题 This question already has answers here : ggplot with 2 y axes on each side and different scales (17 answers) Closed 4 days ago . I created a barchart with ggplot2 geom_bar and want to have two metrics in the bars. I used melt to do so. However, I now need a second y-axis with another scale, because the numbers of the two metrics are too different. In the following the dataframe and the code I used: df <- data.frame(categories = c("politics", "local", "economy", "cultural events", "politics",

问题 I'm am working on a project at the moment where I am trying to create a Hilbert curve using the Python Imaging Library. I have created a function which will generate new coordinates for the curve through each iteration and place them into various lists which then I want to be able to move, rotate and scale. I was wondering if anyone could give me some tips or a way to do this as I am completely clueless. Still working on the a lot of the code. #! usr/bin/python import Image, ImageDraw import

问题 I have a series of CSS hexagons. I would like to apply CSS scale transform for different viewport widths, though gaps are appearing within my hexagon shapes. This problem is most evident on Firefox at any scale value. It also appears in Chrome if scaled to non-integer values. Firefox additionally shows baffling horizontal lines in the :before and :after pseudo elements, though these lines are in the centre of a border and not at the edge of any shape. Snippets A simplified version of my

问题 I'm using FontForge. I'm modifying the lower case q to make a straight-stalked 9. The q has 2 logical parts, the stalk, and the 'c'. The 'c' is too big vertically. How can I scale it down vertically while keeping the vertical stroke widths the same (and not altering any of the horizontal dimensions)? I'm a novice with FontForge, so please spell out your explanation and provide step-by-step instructions. Thanks for your help. 回答1: It sounds like you want to decrease the x-height of the 'q'

问题 I have a data which can be generated like this: set.seed(1) foo <- sample(1:10000,1000) foo[c(1:100)] <- 1 After this to get the zvalues, which are calculated by scale, I used: boo<-rollapply(foo,50,scale) But all the values of boo seems to be NAN. background info: z-score = scale = (x - mean)/ std deviation My first question is why do I get NAN for all the values? For the first 100, I understand that std dev is o . So, I should get Nan only for the first few rows, but I get NAN for all the

问题 I'm trying to make one heatmap using ggplot2 that contains 3 types of variables where each need their own independent legend/scale. I am able to plot them all in one heatmap (pictured below), but I am having trouble separating them to have their own legend. My three categories are the row "Score", "samp1" and the rest of the data. I would like each of these to have their own independent legends with their respective ranges. My only addition would be to have the row score have a green,yellow
