Following effects have been implemented:
- Adjust Channels
The library also supports photoshop like layer blending modes:
- Soft Light
===================================== ##Using NETFx
You need to add five classes (effects.cs,layers.cs,Util.cs,Bitmap.cs,LockBitmap.cs) to your project in order to use NETFx. These classes are based on .NET 4.0 and are independant of any third party library.
After that, just declare an object of both effects 'class' and 'layers' class:
effects effects = new effects(); //contains all the basic effects layers layers = new layers(); //photoshop like layer implementation
- You need to use my wrapper around the .net Bitmap when applying effects, you can use your old bitmap(if you really have to) like this:
Bitmap oldBMP = new Bitmap("megan.jpg"); //this is .NET Bitmap BitmapW BetterBitmap = new BitmapW(oldBMP); //copy the old bitmap into this one.
Otherwise you can do the following too:
BitmapW BetterBitmap = new BitmapW("megan.jpg"); //load from file
Effects and Layers
- After you have a bitmap and some objects ready to use, try some effects:
BitmapW a = new BitmapW("D:\megan.jpg"); //load an image a = effects.sepia(a); //apply the effect pictureBox1.Image = a.GetBitmap(); //show the resulting image
- You can also merge two bitmaps with some blending options(like in photoshop):
BitmapW a = new BitmapW("D:\megan.jpg"); //load an image BitmapW a = new BitmapW("D:\glow.jpg"); //load another image a = layers.merge("softLight",a,b); //merge 'b' onto 'a' as soft light pictureBox1.Image = a.GetBitmap(); //show the resulting image
Sample code in C#
effects effects = new effects(); //contains all the basic effects layers layers = new layers(); //photoshop like layer implementation BitmapW a = new BitmapW("D:\megan.jpg"); //load an image a = effects.sepia(a); //apply the effect pictureBox1.Image = a.GetBitmap(); //show the resulting image
a more complex sample:
BitmapW a = new BitmapW(openFileDialog1.FileName); //load a bitmap BitmapW layer1 = a.Clone(), layer2 = a.Clone(), layer3 = a.Clone(); //make three copies of the image l1,l2,l3 BitmapW res = a.Clone(); //this will hold the final result layer3 = effects.fill(layer3, 167, 118, 12); //layer 3 is a solid fill of this rgb color layer2 = effects.blur(layer2, "gaussian"); //layer2 is a blurred version of original image layer1 = effects.saturate(layer1, -50); //layer1 is a saturated version res = layers.merge("overlay", res, layer1); //merge layer1 onto original with "overlay" layer blending res = layers.merge("softLight", res, layer2); //now merge layer2 onto this, with "softlight" layer blending res = layers.merge("softLight", res, layer3); //now merge layer3 onto this, with "softlight" layer blending res = effects.saturate(res,-40); //apply -40 saturate effect on this now res = effects.contrast(res, 10); //apply 10 contrast pictureBox2.Image = res.GetBitmap(); //show the resulting image
