Here is the Solution I have done with Pixels. Attaching the source code so one can try the exact and get the result. I have sample images of 128×128 (Width x Height). using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Drawing; using System.IO; //using System.Globalization; namespace colorchange { class Program { static void Main(string[] … Read more
Use px or em CSS FONT-SIZE: EM VS. PX VS. PT VS. PERCENT Points (pt): Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in … Read more
It uses pixels, but I’m sure you’re wondering how to use dips instead. The answer is in TypedValue.applyDimension(). Here’s an example of how to convert dips to px in code: // Converts 14 dip into its equivalent px Resources r = getResources(); int px = Math.round(TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, 14,r.getDisplayMetrics()));
Height is the Standard Measure Font height is measured or specified by the height of a line, which is the full height required to display the gamut of characters, including those that dip below the line, like j, and raised elements (accents on capitals, for instance) like Ê. (source: banzaimonkey.net) Fonts in order of appearance: … Read more
Apart from the good answers already given, here’s an example of how to get a simple array structure to walk on. (You can use e.g. Goz’ code for the iteration.) GetDIBits reference @ MSDN You have to select DIB_RGB_COLORS as flag for uUsage and set up the BITMAPINFO structure and the BITMAPINFOHEADER structure it contains. … Read more
If you want to make your image simpler (i.e. with less colors), but good looking, you have a few options: A simple approach would be to divide (integer division) by a factor N the image, and then multiply by a factor N. Or you can divide your image into K colors, using some clustering algorithm … Read more
You can do it a couple of different ways. You can use unsafe to get direct access to the data, or you can use marshaling to copy the data back and forth. The unsafe code is faster, but marshaling doesn’t require unsafe code. Here’s a performance comparison I did a while back. Here’s a complete … Read more
