    There was a plugin named something like PathTool / Drawing. It could make spirals, splines and other complex lines. I cannot find it in Plugin index. I also don't remember exact name. 

     

    I didn't noticed that PDN now has more than 1000 plugins.

    How to merge images into one file?

    in Paint.NET Discussion and Questions

    Posted

    Use this plugin.

     

     

    Import all images as layer. and 'save as' sprite with option as 1 column. Then reopen through recent files. This will save files as vertical sprites.

     

    If you want to do that horizontally

     

    1. import all images in through layers menu.

    2. rotate 90 degree through edit menu.

    3. save as sprite-sheet with option column 1.

    4. go to file menu, and open the new file from recent files.

    5. rotate 90 in opposite direction from edit menu.

    6. save

    Paint.net on Mac?

    in Paint.NET Discussion and Questions

    Posted · Edited by Pratyush

    paint.net for Mac is not going to happen.

     

    Quoted from FAQ:

     

    (1) Will it ever be ported to Mac OS, Linux, or any other operating system?

    (2) What about Mono support? Wouldn't that be really easy?

    We will not be doing any work to directly support Mac OS, Linux, Mono, or any other platform. We are doing this in order to focus on the best quality and support for the platform that we develop on: Windows with .NET. Also, we simply do not have the resources or expertise to do any of this work.

    Please help with "Kill Color Keeper" plugin.

    Hi Everyone,

     

    Being a beginner I know next to nothing about programming and I am trying to achieve something.

     

    Here, I wanted to make amendment in UI for Kill color Keeper like this. This was to include dropdown from Jotaf's original plugin.

    Previous UI was.

    Ke1os7u.png

     

    In UI region I Added, 

    #region UICode
DoubleSliderControl Amount1 = 1; // [0,20] Color tolerance:
ColorWheelControl Amount2 = ColorBgra.FromBgr(0,0,0); // [PrimaryColor] {!Amount3} Select Color
CheckboxControl Amount3 = false; // [0,1] Use specific Values to Select Colors
ListBoxControl Amount4 = 0; // {Amount3} What Color?|What color?|Primary Color|Secondary Color|White|Gray|Black
RadioButtonControl Amount5 = 0; // [1] Functions|Keep Color|Kill Color
IntSliderControl Amount6 = 0; // [0,255] Consider transparent any alpha smaller than:
IntSliderControl Amount7 = 255; // [0,255] {Amount5} Consider transparent any alpha greater than:
#endregion

    And for assigning input color value I updated this line 

    ColorBgra color = Amount2;

    into this block of codes. 

    ColorBgra color;
    if(Amount3)
        color = Amount2;
    else
      //selecting things from dropdown
        switch(Amount4)
        {   
            case 0: // Primary color
          
                color = (ColorBgra)EnvironmentParameters.PrimaryColor;
                break;
            case 1: // Secondary color
                color = (ColorBgra)EnvironmentParameters.SecondaryColor;
                break;
            case 2: // White
                color = ColorBgra.White;
                break;
            case 3: // Gray
                color = ColorBgra.Gray;
                break;
            default: // Black
                color = ColorBgra.Black;
                break;
        }

     

    So, In UI output is as expected, for the drop-down & Color-Wheel are enabled and disabled and working as expected. But somehow the selection of color is not working at all.

     

    i.e. The behavior is I am seeing.

    • When checkbox for "specific values" is checked, Dropdown is enabled as expected, I can choose color from dropdown but Output for the selected Color from dropdown doesn't reflect on Canvas.
    • When checkbox for "specific values" is unchecked,  ColorWheel is  enabled as expected, I can change value for color but Again output for the selected Color from ColorWheel doesn't reflect on Canvas.

     

    UI is eternally struck on Primary Color which is default value. If I comment the whole "if else and switch" block of new code,  and replace it with simply "ColorBgra color = Amount2;" every thing starts working again magically. How to make the it work?  I am at my wit's end and I can't understand what is happening here. :cry::cry::cry:.

    Thanks @Ego Eram Reputo for all of the work. 

    Just two suggestion. :) :) 

    1) Tinker the description a bit, :)Gradual stripes can draw stripes in any direction and nubs cab be set anywhere.

    2) In Jotaf's Grim Color Reaper's discussion please mention about updated version, so that people visiting that place know that an updated version exists.

     

    Thank you so much. :beer::mrblue:

    In the documentation, I referred to these keyboard combinations like this;

     

    Tool Shortcuts

    Rectangle Select

    S

    Lasso Select

    S x 2

    Ellipse Select

    S x 3

    Magic Wand Tool

    S x 4

    Shapes

    O x 2

    Move Selected Pixels

    M

    Move Selection

    M x 2

    (of course it's laid out much better than that!)

     

    If I correctly remember.....

    Once you have selected Shapes tool by O X 2, it's 'A'. 'A' is chord to select Shapes.

    i.e.

     

    Rectangle Shape

    A

    Rounded Rectangle

    A x 2

    Ellipse Shape

    A x 3

    Rhombus

    A x 4

    Trapezoid

    A x 5

    And so on...
