There is a quite simple answer to how to encrypt files. This script uses the XOR encryption to encrypt files. Encrypt the file a second time to decrypt it. #include <iostream> #include <fstream> #include <string> using namespace std; void encrypt (string &key,string &data){ float percent; for (int i = 0;i < data.size();i++){ percent = (100*i)/key.size(); … Read more
Don’t override the paint() method. Custom painting is done by overriding the paintComponent() method of a JPanel (or JComponent) and then you add the panel to the applet Don’t invoke repaint() from any painting method. This will cause an infinite loop. Don’t use sleeping code inside a painting method. If you want animation then use … Read more
You have two lines there. What you want to do is to pick the closer line for each pixel, and calculate the distance to it. This will be your intensity at a given point. Furthermore do a fade to black as you approach the bottom of the image (use your pixel’s y position to do … Read more
No, implementing something like OpenGL is not possible. Since the time OpenGL has decended from the heavens complete, writing something like it was forbidden by all common religions. But really, what you’ll actually need is about 21 years of work, a few thousands of developers and broad support from all industry leaders, so yea, piece … Read more
To draw the I love you text you can call: g.drawString(…) method and position it over the T-Shirt. Next to draw a heart shape, you can call the same method using the ASCII’s heart shape: ♥ But be sure to use a nice (big enough) font so it can be visualized correctly, for example: g.setFont(new … Read more
What you are describing is a LOT of work and something impossible for someone with limited programming experience such as yourself. C++ is neither an easy language nor a language that forgives.. it’s not just about learning the syntax (as is the case with processing or similar languages with automatic garbage collection) – it’s also … Read more
I’m assuming you’re rendering text to an arbitrary component (via paintComponent()) rather than trying to modify the color of text in a JTextPane, JLabel, or other pre-existing widget. If this is the case, you should look into using an AttributedString along with TextAttribute. These allow you to assign different styles (color, font, etc.) to various … Read more
You can turn on a given pixel, but this requires platform specific code and may not portable when the OS or platform changes. My understanding is you want direct access to the screen buffer with nothing between stopping you. Here’s the way to go. Common Research On your platform, find out the graphics controller, brand … Read more
There is only one problem in your code: Change for (int j=0; j<values[i].length; i++) to for (int j=0; j<values[i].length; j++) You put i++ instead of j++. 1 solved Trying to create a chessboard using an array and graphics
Almost all programming languages have libraries that help you create a GUI (Graphical User Interface). Most programming languages, including C++, C#, and Java are general-purpose programming languages – you can use them to program whatever you want. For Java for example, see this tutorial: Creating a GUI With JFC/Swing. If you want to write an … Read more

Not sure it will help but you can try changing some of the Graphics properties. For example: g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); 0 solved Low Quality Rendering Rotating Images
You could make another class in the same folder and let the first one run the second when a button is clicked. If you want any example/ more details/or anything you don’t understand, just leave a comment 2 solved Can i make more than one graphics console in Java?
It’s not possible to do imagesc and axis off at the same time. However, you can modify the imagesc code to achieve this but you will not get MathWorks support for the modified version. To avoid the graphical artifacts, try different figure renderers: painters, opengl, … You can also try the startup flag -softwareopengl. solved … Read more
