TR's Film Stock Plugin V1.2.0 (Dec 18 2013)

[TechnoRobbo]

TechnoRobbo's Film Stock Plugin v 1.2.0

A photographer often chooses his film speed to, among other things, control the contrast of the image.

High ISO yield high contrast images and low ISO yield low contrast.

 

TR's Film Stock re-interprets the image's contrast without loosing the images dynamic range.

Low contrast doesn't fog the image shadows, and high contrast doesn't wash out highlights.

 

V1.2.0 Code Updated for Speed

V1.1 Updated for Paint.net 4.0

I thought you were on holiday!

Haven't played with this one yet - bit confused by the code - (I often am).
Code looks like there should be a checkbox and an integer slider, screen shot just has int slider?

Many many thanks for all the new plugins (and example code) - go and enjoy your holiday (vacation)!

all the best

I like this!

Good job again! Keep making some, you are doing great.

Red,

 

Yes I finished this at night in the hotel room, I used my daughters laptop , thats why the menu's purple

Code looks like there should be a checkbox and an integer slider, screen shot just has int slider?

 

the invisible checkbox is used as a global variable. it's a semaphore used to accelerate the render.

The biggest issue that slows down the code is the line by line way PDN feeds the image giving the user a realtime preview and thumbnail.

 

One of several work arounds I use is the semaphore. I couple it with a try catch(needed if user changes settings often)  and a keep alive code for the ui dialog so it displays status.

 

Note I use it with the selection and not the rect parameter. I process the whole image once and use the semaphore to ignore the subsequent calls.

 

I use the pdnregion if I want to process only the selected pixels.

 

If I were to remove the wrapper the code would take forever since it's calculatuing the brightest and darkest pixels. and it would scan for them on every scanline, yikes

 

 

I use this wrapper for slow code:

 

#region UICode 
bool Amount1 = true; // [0,1] 
#endregion 

void Render(Surface dst, Surface src, Rectangle rect)
{
     if (Amount1){
          // next two lines are necessary if you are using system graphics. 
          Rectangle sel = EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt();
          dst.CopySurface(src, sel.Location,sel);
         //========================= 
          Amount1=false;
          try {

               //your code goes here
     
          }catch(Exception e){}

     }else{
      //======= next code is a keep alive for dialog box 
     //so users know its working. 
            ColorBgra CP=dst[0,0];
            dst[0,0]=CP;
     }
}

Hi TR,

Thanks for the explanation and wrapper code example. All just a little bit clearer now! - it can be slow getting new ideas into an old head like mine.

Enjoy the rest of your time off.
Useful effect Btw. Thanks.

Red,

Your Welcome, I'm 51 BTW, and we're not fossils yet.

[TechnoRobbo]

wouldn't it be more @ home in Effects >>> Photo ?)

Sure, if you wanna be all "logical" about it. I suppose I could skip the hotel's free Twerking lessons and update the menu.

 

Thanks for the tip Welsh, I uploaded the change. I kept version the same since it's functionally the same program.

Beautiful Pic. I had to download and flip between the two but I see you've richened the green hues.

All features of the Plugin - now work with 3.511 and 4.0 

[TechnoRobbo]

Version 1.2.0 Updated for Speed

[skullbonz]

I have been flipping between both images that Seerose posted and I can not see a difference. Even after seeing TR's reply I studied the green until my eyes hurt and still see no difference. I can definitely see the differences in TR's pics though. 

[TechnoRobbo]

Skull,

This should help

Here's an XOR of the 2 images - XORs show the difference in color - Identical details come out black.

[skullbonz]

Now you really got me scratching my head,lol  

[TechnoRobbo]

Skull, yes it's subtle

 

[skullbonz]

Lol,ok,Now I see it. Thanks for showing me the light.
