Lens flare WIP

[MadJik]

Searching help for debug this / or improve the code.

 

 

 

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?

Thanks.

I think I can help you with all of those things, but your link to the source code doesn't work.

Oops, typo in the link... Ok now.

Most of the rendering issues were solved by utilizing OnSetRenderInfo.

Done.

Take a look in InitialInitToken(). I placed some code there that should work.

You just need to change the TabIndex on each control. I've done this for you; VS Designer makes it extremely fast and easy to update them all.

I didn't add these, but I'm guessing the issue was that they got into a update loop.

i.e. Slider updates NumBox, causing the NumBox to update the Slider, causing the Slider to update the NumBox, ect.

Just create a flag so that doesn't happen. Take a look at my Pie Chart plugin if you're not sure.

@toe_head2001 many thanks, it's much better. I have to dig more in the code to understand the changes.

 

For the tabulation sequence, I want to add a checkbox for the user to choose between horizontal or vertical tabulation.

I will Something try with "foreach (Control control in this.Controls)".

New version:

 

Visual Studio Sources

The blur is visible while the UI is open. After Ok, no more blur.

Ctrl-F the blur is applied.

 

My config dialog design is empty, so I use the cs editor...

@toe_head2001 Still haven't found a way to solve the final blur. Just disabled it...

 

I'm not sure about the correct words to use in English for the flare (circle/hexagon) and the flake (star). Any clue?

I'll take a look at it later today.

Hmm... The issue with Blur when pressing OK... I can't explain it.

It works when the dialog is open, and it works when you press Ctrl+F.

 

I use very similar code in my Blur Fill plugin, and it works fine there.

Maybe there's a bug in paint.net that affects custom UI effects, but not IndirectUI effects... I don't know; more testing would need to be done.

@toe_head2001 thank you for your time. I did also that kind of tests, I was about to turn crazy about this.

 

I think I will release without blur.

Then try to adapt an old codelab sample for next version.
