colour changing plugin

[bitchcraft]

hey guys, i'm looking for a very simple plugin & i'm sure it already exists, i just can't find it.

all i want is a plugin that will change an entire layer's colour to a hex/rgb code that i can input. i don't want any info on the colour changer tool or using the fill bucket, for clarification; i want a plugin that will allow me to put in a hex/rgb code and when applied will change the entire layer to said colour (other than transparent areas, obviously). thanks in advance!

Here is a CodeLab script to do what you want:

 

// Name: with Named Color
// Submenu: Fill
// Author: BoltBait
// Title: Fill with Named Color
// Version: 1.0
// Desc: Fill selection with named color
// Keywords: fill|hex
// URL: http://www.BoltBait.com/pdn
// Help: Fill with Named Color v1.0\nCopyright ©2018 by BoltBait\nAll rights reserved.
#region UICode
TextboxControl Amount1 = "#0088ff"; // [0,255] Enter a color by name (green) or by hex code (#00ff00):
CheckboxControl Amount2 = true; // [0,1] Keep original alpha
#endregion

void Render(Surface dst, Surface src, Rectangle rect)
{
    bool Valid = true;
    ColorConverter c = new ColorConverter();
    ColorBgra nc;
    try
    {
        nc = (Color)c.ConvertFromString(Amount1);
    }
    catch
    {
        nc = Color.Red;
        Valid = false;
    }
    for (int y = rect.Top; y < rect.Bottom; y++)
    {
        if (IsCancelRequested) return;
        for (int x = rect.Left; x < rect.Right; x++)
        {
            if (Valid)
            {
                if (Amount2) nc.A = src[x,y].A;
                dst[x,y] = nc;
            }
            else
            {
                dst[x,y] = src[x,y];
            }
        }
    }
}

It prompts you for a string.  You can enter any of the standard color names or if you start with a hash tag, you can enter a hex code.  It supports the following entries: https://www.w3schools.com/colors/colors_names.asp

 

How to use this script?  Easy!  Just go here: http://boltbait.com/pdn/codelab and download and install CodeLab.  Paste this script into CodeLab and build yourself a DLL to install into paint.net.

Fix untested, sloppy code.

first off, thanks so much for your help, i really appreciate it! 

i've created the dll and it seems to be working properly in terms of prompting me for a colour or hex, but for some reason when i enter any value at all, it crashes immediately

i'm probably just doing something stupid but i'm awful with code so if you know what it is i'm doing wrong i'd really appreciate more help :'D

 

here's the error message:

Nope.  It was me.

 

All fixed.

 

If you enter something invalid, it just won't change the image.

 

That means, as you type a color word, R-E-D, for example, you won't see a change until you type the letter D.

Welcome Bitchcraft! You might want to try Remake's Color Range plugin.

boltbait, thank you so much for your help, the code works perfectly now! i've donated on the codelab page, sorry i can't afford much 

thanks to everyone else too for your additional suggestions
