text

问题 I have an input image of a paragraph of text in single line spacing. I'm trying to implement something like the line spacing option to increase/decrease space between text lines in Microsoft Word. The current image is in single space, how can I convert the text into double space? Or say .5 space? Essentially I'm trying to dynamically restructure the spacing between text lines, preferably with an adjustable parameter. Something like this: Input image Desired result My current attempt looks

问题 I have a problem when adding values in a barplot in R.

问题 I am trying to draw my own graphic within a kivy 'canvas'. For now I have a red or green rectangle which changes colour once per second, but I want to add a changing text label. After a little searching it appears that there isn't a "Text" Instruction which can be added to the canvas. I have found a few references to using a Label() widget as well as the canvas Instructions, but this does not seem ideal, and also I can't seem to get it to render more than once. Here's my object as it stands

问题 How do I sort a text file by three columns with a specific order to those columns in Python? My text_file is in the following format with whitespaces between columns: Team_Name Team_Mascot Team_Color Team_Hometown Number_of_Wins Team_Coach Example: Bears LittleBear Blue Beartown 15 BigBear I want to sort it by Team_Color first, Team_Hometown second, and Number_of_Wins third in ascending order. Therefore the attributes: Bears Blue Beartown 15 Coach1 Bears Red Dogtown 30 Coach6 Bears Blue

问题 Suppose I have a large campsite like "seating" chart with several hundred lots sectioned off and outlined in photoshop. (each lot is roughly a square) Every lot needs to be numbered in photoshop and also editable in the future in case of changes. The lots are scattered and curve around the landscape so entering text in one layer seems out since for example lot 27 with be on the right and rotate 20 degrees to match the lot and yet lot 185 might be way over on the left at a far different angle.

问题 I'm trying to find the first most frequent, the second most frequent, ..., the last most frequent words/categories in the following text cat . library(stringr) cat <- c("AA","AA","AA","Ee","Dd","Ee","Bb","Cc","Cc","Cc") OUTPUT that I need: most1 AAA Cc most2 Ee most3 Bb Dd Can one help me in this regard? Tnx! 回答1: You can use table like: sort(table(cat), TRUE) #cat #AA Cc Ee Bb Dd # 3 3 2 1 1 And as a character vector: x <- table(cat) x <- rev(do.call(rbind, lapply(split(names(x), x), paste

问题 Guys I'm trying to find a way to don't have the awk error "too many open file" . Here's my situation: INPUT : ASCII file, lot of line, with this scheme: NODE_212_lenght.._1 NODE_212_lenght.._2 NODE_213_lenght.._1 NODE_213_lenght.._2 In order to split this file with every record with the same NODE number, I've used this one-liner awk command awk -F "_" '{print >("orfs_for_node_" $2 "")}' <file With a file composed by lots of lines, this command keeps sayin "too many open files" . I've tried

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
