The following plugin has an initial blur, followed by a brightness and contrast adjustment

Is there a way to call the brightness and contrast adjustment before applying the blur? I want to add this to my HDR effect, though I already built it without the adjustment and blur as Version 1.0 (I still haven't shared it btw)

 

Edit: (Actually, I just already did - along with my Color Intensifier plugin.)

Already shared it.

Show us the script.

[Sakana Oji]

I seem to have lost it somehow. Basically it's an effect that applies the Frosted Glass effect, followed by the Median effect. But I don't know how to show it to you. I apologize.

Well, we can't fix the error if you can't show us the script that is giving you the error.

I tried my best to recreate it:

// Name: Gaussian Blur with Brightness and Contrast
// Submenu: Blurs
// Author: MJW
// Title: Gaussian Blur with Brighness and Contrast
// Desc: Gaussian Blur with Brightness and Contrast (test multiple built-in effects)
// Keywords: Gaussian blur contrast brightness test multiple built-in effects
// URL:
// Help:
#region UICode
DoubleSliderControl Amount1 = 3; // [0,5] Pressure
DoubleSliderControl Amount2 = 0; // [0,200] Minimum Scatter Radius
IntSliderControl Amount3 = 2; // [1,8] Quality
IntSliderControl Amount4=1; // [1,200] Radius
IntSliderControl Amount5=10; // [0,100] Percentile
#endregion


// Here is the main render loop function
void Render(Surface dst, Surface src, Rectangle rect)
{
    // Setup for calling the Frosted Glass effect
    FrostedGlassEffect frostedEffect = new FrostedGlassEffect();
    PropertyCollection frostedProps = frostedEffect.CreatePropertyCollection();
    PropertyBasedEffectConfigToken FrostedParameters = new PropertyBasedEffectConfigToken(frostedProps);
    FrostedParameters.SetPropertyValue(FrostedGlassEffect.PropertyNames.MaxScatterRadius, Amount1);
    FrostedParameters.SetPropertyValue(FrostedGlassEffect.PropertyNames.MinScatterRadius, Amount2);
    FrostedParameters.SetPropertyValue(FrostedGlassEffect.PropertyNames.NumSamples, Amount3);
    frostedEffect.SetRenderInfo(FrostedParameters, new RenderArgs(dst), new RenderArgs(src));
    // Call the Frosted Glass function
    frostedEffect.Render(new Rectangle[1] {rect}, 0, 1);  
    
    // Adjust median.
    MedianEffect medianEffect = new MedianEffect();
    PropertyCollection medianProps = medianEffect.CreatePropertyCollection();
    PropertyBasedEffectConfigToken medianParameters = new PropertyBasedEffectConfigToken(medianProps);
    medianParameters.SetPropertyValue(MedianEffect.PropertyNames.Radius, Amount4);
    medianParameters.SetPropertyValue(MedianEffect.PropertyNames.Percentile, Amount5);
    medianEffect.SetRenderInfo(medianParameters, new RenderArgs(dst), new RenderArgs(dst));
    // Call the Median function
    medianEffect.Render(new Rectangle[1] {rect}, 0, 1);

    // Now in the main render loop, the dst canvas has a crayon version of the src canvas
    // The dst canvas has the contrast adjusted.
}

Weirdly the error seems to have gone, but now it makes the picture look all weird and glitchy - NOT the kind of effect I want.

 

The picture below proves it:

 

 

How to fix this, please?

Here's your problem:

 

medianEffect.SetRenderInfo(medianParameters, new RenderArgs(dst), new RenderArgs(dst));

You can't render the median effect to the same canvas you're rendering from.

 

You should probably read the tutorials on my web site:

(specifically part 3 & 7)

Okay Bolty

[Sakana Oji]

Okay here's my real actual code that I first worked on (not recreated):

 

// Name: Crayon
// Submenu: Artistic
// Author: Sakana Oji
// Title: Crayon
// Desc: Gives the image a crayon effect
// Keywords: crayon artistic
// URL:
// Help:
#region UICode
DoubleSliderControl Amount1 = 3; // [0,10] Thickness
DoubleSliderControl Amount2 = 0; // [0,200] Minimum Scatter Radius
IntSliderControl Amount3 = 2; // [1,8] Quality
IntSliderControl Amount4=1; // [1,5] Radius
IntSliderControl Amount5=10; // [0,100] Percentile
#endregion


// Here is the main render loop function
void Render(Surface dst, Surface src, Rectangle rect)
{
    // Setup for calling the Frosted Glass effect
    FrostedGlassEffect frostedEffect = new FrostedGlassEffect();
    PropertyCollection frostedProps;
    // Call the Frosted Glass function
    frostedEffect.Render(new Rectangle[1] { rect }, 0, 1); 
    
    // Adjust median
    MedianEffect medianEffect = new MedianEffect();
    PropertyCollection medianProps = medianEffect.CreatePropertyCollection();
    PropertyBasedEffectConfigToken medianParameters = new PropertyBasedEffectConfigToken(medianProps);
    medianParameters.SetPropertyValue(MedianEffect.PropertyNames.Radius, Amount4);
    medianParameters.SetPropertyValue(MedianEffect.PropertyNames.Percentile, Amount5);
    medianEffect.SetRenderInfo(medianParameters, new RenderArgs(dst), new RenderArgs(dst));
    // Call the Median function
    medianEffect.Render(new Rectangle[1] {rect},0,1);

}

[ReMake]

@Sakana Oji, I appreciate your youthful enthusiasm and maximalism, but you are violating item 2) of The Rules (I hope the admins and mods will be lenient to you again - we all make mistakes sometimes). 
No offense, but I suggest you create your own topic in the proper thread as it did @xod with its Unfinished plugins.

[Sakana Oji]

Okay, none taken

As ReMake has indicated, this discussion has wandered off the original topic. I've split into it's own thread.
