Color Intensifier and HDR - My first two plugins

[Sakana Oji]

Created with a little help from ReMake, BoltBait and others!

 

Color Intensifier is based on this tutorial by xmario, while HDR is based on applying an inverted, blurred and black and white overlay on the original image.

Here is the code for Color Intensifier:

 

// Name: Color Intensifier

private UnaryPixelOps.Invert invertOp = new UnaryPixelOps.Invert();

// Setup for using Reflect blend op
private BinaryPixelOp reflectOp = LayerBlendModeUtil.CreateCompositionOp(LayerBlendMode.Reflect);

protected override void OnDispose(bool disposing)
{
    // Release any surfaces or effects you've created.
    if (bacAdjustment != null) bacAdjustment.Dispose();
    bacAdjustment = null;
    base.OnDispose(disposing);
}

void PreRender(Surface dst, Surface src)
{
    bacProps = bacAdjustment.CreatePropertyCollection();
    PropertyBasedEffectConfigToken bacParameters = new PropertyBasedEffectConfigToken(bacProps);
    bacParameters.SetPropertyValue(BrightnessAndContrastAdjustment.PropertyNames.Brightness, 0);
    bacParameters.SetPropertyValue(BrightnessAndContrastAdjustment.PropertyNames.Contrast, -1);
    bacAdjustment.SetRenderInfo(bacParameters, new RenderArgs(dst), new RenderArgs(src));
}

// Here is the main render loop function
void Render(Surface dst, Surface src, Rectangle rect)
{
    // Call the Brightness and Contrast Adjustment function
    bacAdjustment.Render(new Rectangle[1] {rect},0,1);

    // Now in the main render loop, the dst canvas has an adjusted version of the src canvas
    for (int y = rect.Top; y < rect.Bottom; y++)
    {
        if (IsCancelRequested) return;
        for (int x = rect.Left; x < rect.Right; x++)
        {
            ColorBgra CurrentPixel = dst[x,y];

            // TODO: Add additional pixel processing code here
            CurrentPixel = desaturateOp.Apply(CurrentPixel);

            CurrentPixel = invertOp.Apply(CurrentPixel);

            CurrentPixel = reflectOp.Apply(src[x,y], CurrentPixel);

            dst[x,y] = CurrentPixel;
        }
    }
}

 

And this code is for HDR:

// Setup for using pixel op
private UnaryPixelOps.Desaturate desaturateOp = new UnaryPixelOps.Desaturate();
private UnaryPixelOps.Invert invertOp = new UnaryPixelOps.Invert();

// Setup for using Overlay blend op
private BinaryPixelOp overlayOp = LayerBlendModeUtil.CreateCompositionOp(LayerBlendMode.Overlay);

protected override void OnDispose(bool disposing)
{
    // Release any surfaces or effects you've created.
    if (blurEffect != null) blurEffect.Dispose();
    blurEffect = null;
    base.OnDispose(disposing);
}

void PreRender(Surface dst, Surface src)
{
    blurProps = blurEffect.CreatePropertyCollection();
    PropertyBasedEffectConfigToken BlurParameters = new PropertyBasedEffectConfigToken(blurProps);
    BlurParameters.SetPropertyValue(GaussianBlurEffect.PropertyNames.Radius, Amount1);
    blurEffect.SetRenderInfo(BlurParameters, new RenderArgs(dst), new RenderArgs(src));
}

// Here is the main render loop function
void Render(Surface dst, Surface src, Rectangle rect)
{
    // Call the Gaussian Blur function
    blurEffect.Render(new Rectangle[1] {rect},0,1);

    // Now in the main render loop, the dst canvas has a blurred version of the src canvas
    for (int y = rect.Top; y < rect.Bottom; y++)
    {
        if (IsCancelRequested) return;
        for (int x = rect.Left; x < rect.Right; x++)
        {
            ColorBgra CurrentPixel = dst[x,y];

            // TODO: Add additional pixel processing code here
            CurrentPixel = desaturateOp.Apply(CurrentPixel);

            CurrentPixel = invertOp.Apply(CurrentPixel);

            CurrentPixel = overlayOp.Apply(src[x,y], CurrentPixel);

            dst[x,y] = CurrentPixel;
        }
    }
}

Removed Takeafile link, removed Dropbox links and added zip attachments

AHAHAHAHAHAHHAAA! Oh my grease, the code tag turned that last word into a code! Well at least I know that they work...

I have some feedback regarding ways to improve and simplify your code. I'm about the walk out the door, so I'll get back to later tonight.

How does that equate to HDR?

Download them as a 2-plugin pack: https://takeafile.com/?f=wananekike

 

No offense directed to you, but what a awful way to distribute your plugins. Please use a different service or host, or better yet, attach a ZIP file to the forum.

[Ego Eram Reputo]

Yup. I'm backing toe_head2001 with the request for an attached ZIP.

 

 

Neither source code compiles as posted. Both give me this error in codeLab....

You aren't doing any per-pixel processing in either effect, so you don't need the X,Y loops.

 

For example, your "HDR" plugin can go from this:

void Render(Surface dst, Surface src, Rectangle rect)
{
    // Call the Gaussian Blur function
    blurEffect.Render(new Rectangle[1] {rect},0,1);

    // Now in the main render loop, the dst canvas has a blurred version of the src canvas
    for (int y = rect.Top; y < rect.Bottom; y++)
    {
        if (IsCancelRequested) return;
        for (int x = rect.Left; x < rect.Right; x++)
        {
            ColorBgra CurrentPixel = dst[x,y];

            // TODO: Add additional pixel processing code here
            CurrentPixel = desaturateOp.Apply(CurrentPixel);

            CurrentPixel = invertOp.Apply(CurrentPixel);

            CurrentPixel = overlayOp.Apply(src[x,y], CurrentPixel);

            dst[x,y] = CurrentPixel;
        }
    }
}

To this:

void Render(Surface dst, Surface src, Rectangle rect)
{
    // Call the Gaussian Blur function
    blurEffect.Render(new Rectangle[] {rect}, 0, 1);

    desaturateOp.Apply(dst, rect);

    invertOp.Apply(dst, rect);

    overlayOp.Apply(dst, src, dst, rect);
}

 

 

Also a note about the Dispose override. Please place objects within a diposing condition.

Yes, I know CodeLab wrote this code for you, but you used an old version. The newest version of CodeLab corrects this oversight.

protected override void OnDispose(bool disposing)
{
    if (disposing)
    {
        // Release any surfaces or effects you've created.
        if (blurEffect != null) blurEffect.Dispose();
        blurEffect = null;
    }
  
    base.OnDispose(disposing);
}

Maybe you have the error because you don't have the latest version of CodeLab - and you know what? I'm done with Takeafile now anyway. I'm heading back to Dropbox from now on.

[Ego Eram Reputo]

Just attach a zipped file to the first post.

I think I already did... did I?

[Ego Eram Reputo]

No. You posted Dropbox links to the zipped files. You can attach the files directly to the first post in this thread. This is the preferred method as users don't have to rely on any external host. Meaning the plugins will be available to forum users because they are actually attached to the forum.
