.net photo select 'wand' functionality -


Can I simulate wand functionality in my normal photo editor? To wit. The user clicks on a piece of photo and the app automatically selects the surrounding X pixels based on a given factor (usually tolerance threshold).

How can I do this? Any thoughts on .NET? Thank you

You have to manipulate the basic pixels to accomplish this, I start by storing the color of that pixel Which I clicked, then the induction of a 2D array which is the same dimension as the image. Change the int associated with the pixel that was clicked on 1. At that point, you only have to use a pseudo-mapping algorithm so that it can be exploded outside, by changing the mailing pixels from "1" in their array, and non-matching pixels "1".

After all, you will have a maniper-esque escad 2d array with the heart of 1s and the edges of -1, and then the uncontrolled area will still be at 0. 1S becomes the selected area

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
