draw

问题 I want to be able to scale text-based objects (for example with classes and subclasses of IText, Textbox) without stretching the text inside of the object. The interaction of scaling and moving is on user-side (UI), not programmatically (I am working on a drawing editor). The behaviour I am looking for is similar to the one in the sticky notes apps: You can scale the paper but this action does not scale your text too. I have already checked this, but this is only for horizontal prevention:

问题 We currently have a leaflets map that plots several points. The service (consumed by the map) includes, among other things, the coordinates and the path for a static svg icon. That's working fine. The next step is to create the actual icon so it looks like the icon below. In this example, there are 3 "groups" with 4 "lines" each. Each "line" has its own azimuth (the angle). Also, each "line" has its own length. The angle is the same any way you look at it, but the length is in miles, since

问题 New to programming, I am trying to plot road boundary-like lines. Basically, I am creating something like a road map and I want a rectangle to always be moving through the trajectory (I mean, the x, y coordinates of the rectangle increase with relation to the lines). The idea is like the image below. Can anyone help me? How do I create and plot the red lines as well as the black rectangle which is moving in the direction of the arrows? UPDATE: I need to check that the distance from the

问题 I have been trying to modify the code from this Tutorial so that after a bullet strikes an enemy the player.png image is shown at position x = 60 and y = 48 . But the image does not remain fixed , it just appears and disappears. I don't know exactly where the wrong or missing element is in the code but I suspect that one of the causes is some misuse of my part of the for loop within the draw_reaction function. My player.png image My MWE code: import pygame import random # Define some colors

问题 I'm trying to animate a rectangle based on a coordinate determined by for-loop, inside a button. Here is my JComponent Class: public class Rect extends JComponent { public int x; public int y; public int w; public int h; public Rect (int x, int y, int w, int h) { this.x = x; this.y = y; this.w = w; this.h = h; repaint(); } @Override public void paintComponent(Graphics g) { Graphics2D g2 = (Graphics2D) g; super.paintComponent(g); g2.setColor(Color.green); g2.drawRect(x+15, y+15, w, h); } } and
