    Lens Flare

    What's this?

    “Lens flare is created when non-image forming light enters the lens and subsequently hits the camera's film or digital sensor. This often appears as a characteristic polygonal shape, with sides which depend on the shape of the lens diaphragm…”

    How to install

    Close Paint.net

     

    Classic version of Paint.net

    Unzip and (re)place the DLL in your Effect folder usually:

    C:/Program Files/Paint.NET/Effects (please reverse / for correct path)

     

    Microsoft Store version of Paint.net

    Unzip and (re)place the DLL in your Effect folder usually:

    You have to adapt for your language My Documents

     

     

     

    Thanks to

    @toe_head2001 for help with windows form issues (dark theme and good advices).

     

     

     

    How to use it

    LF_Tuto1b.gif

     

    First of all the plugin is searching for the brightest point of the active layer. If the layer is empty or monochrome, the top left corner is the default point.

    Then from this point passing through the center of the canvas, an imaginary line is used to place each of the fourteen shapes defined by the grid of settings.

    Flares are concentric circles, hexagons and other shapes with a fading white to gray.

    Flakes are rays.

     

    NEW: Up to 10 bright points could be placed and found around the canvas. Use the pen to spot single pixels with same bright color. 

     

    The User interface

    This plugin is added to the menu Effects, submenu Render.

     

    lensflare_UI.png

     

    The interface is divided in several areas:

     

    Area 1 common factors

    Distance factor

    Set the distance adjustment to the center of the canvas. Default distance is estimated by the white point.

     

    Radius factor

    Overall adjustments of the radius of the shapes.

     

    FlaKe intensity factor

    Change luminosity of all flakes.

     

    FlaRe intensity factor

    Change luminosity of all flares (circles, hexagons and other shapes).

     

    FlaKe width of rays

    Ratio to change the width of the rays of the flakes.

     

    FlaRe width adjustment

    Change thickness of concentric shapes (circles, hexagons and other shapes).

     

    Final blur

    The effect is better with a small blur. The blur is applied on the active layer. You should use a separated layer to keep your image unblurred.

     

     

    Area 2 FX table

    This table define each shape of the lens flare (FX).

    The first column shows a symbol of the shape.

    The default values are based on several samples I found on the web.

     

    FX type

    Select the FX type: 0=none, 1=circle, 2= star, 3=hexagon. This changes the symbol.

    New shapes added: 4=diamond, 5=pentagon, 6=star, 7=flower, 8=triangle.

     

    Distance

    Set the distance to the center of the FX. The positive distances are the farthest, the negative ones are the closest. The shapes are drawn in the order from top to bottom, overlapping each other.

     

    Int radius

    Value for the internal radius of the shape (zero for a filled shape).

    Checkbox above Int radius

    Check the box to switch to a percentage based on the external radius. It’s easy to set an internal radius at 80% of the external radius.

     

    Ext radius

    Value for the external radius of the shape.

     

    Ray/Circle

    For flake, define the number of rays to draw the star.

    For flare, define the number of concentric shapes to draw.

    .

    Invert

    0=gradient from white (inside) to black (outside).

    1=gradient from black (inside) to white (outside).

     

    Grey level

    Set the luminosity limit for the FX.

    Checkbox above Grey level

    Check the box to use the primary and secondary colors.

     

    Angle

    Set the rotation angle for the FX.

     

    Area 2b tabulation sequence

    Click on this picture to change the tabulation sequence in the table.

    Green/Vertical: allows to fill the table column per column, going through a parameter for all the FX.

    Blue/Horizontal: allows to fill the parameters FX per FX.

     

     

    Area 3 Set all

    Enter a value in the dark cell to set all values in the column above at once.

     Click on the lockers to fix a line so the “Set all” won’t change locked FX.

     

    Area 4 XML Settings

    Menu with save/load possibilities.

     

    Smart values button

    Set the range of values you need on the first and the last lines. Then when you click on the Smart values button, the values are calculated and evenly distributed over the unlocked lines. Columns updated by this button are: Distance, Int radius, Ext radius, Rays/circles, Grey level and Angle. No change for locked lines and no change if first and last values of a column are equals.

     

    Help button ?

    Click on the ? (top right of the interface) to open this post.

    Seems there are some issues.....

     

    MadJik, did you edit the button after it was posted? Did it show up at all?

    I add the button to the text then I refresh by F5 to have the attached file number. Then submit. Till this the button is ok.

     

    When the post is "posted", the button is replaced by the text...

     

    Could it be a browser problem?

     

    Lens flare WIP

    in Plugin Developer's Central

    Posted

    Searching help for debug this / or improve the code.

     

    help1.png

     

     

    This effect is drawing 14 forms (circle/hexagone/rays).
    It should look like a lens flare effect.
    It needs a layer filled with black color. You could set the origin of the light by plotting a single white pixel on the canvas.
    The center of the canvas is the second point used to draw a virtual straight line.
    Each centers of the 14 forms are placed over this line.

     

    Settings allow to choose each type of form, distance, radius etc.
    14 forms x 7 parameters, this is a number of 98 datas to define/handle.
    Plus some other (7) common parameters.

     

    The problems are:
    -(ok)changes on the 98 settings run the rendering.
    -(ko)changes on the 7 common parameters have not effect.
    -(ko)first cycle of the effect doesn't work (linked?).
    -(ko)tried to have sliders for the 7 common parameters (failed so I delete these sliders).

     

    Instead of checking each change of parameters, I use a single counter++ to check for any change.

    To make it works, I use the button reset of a common parameter or make a change on one of the 98 settings.

     

    Other points to solve:
    -dark theme for Windows form effects?
    -XML save and load works fine. Any idea to set a saved file as default setting to load when the effect is openning?
    -Tab (tabulation sequence) is set to go column by column. Any idea to have a checkbox to change it to go row by row?
