# librawprocessor #

* A library for processing 16bit gray scaled medical RAW images.

* Supports multi-platforms: Windows, Linux and MacOSX.

* Reading 8 to 16bit gray scaled RAW image and make its downscale window size into 8bit another RAW image, or reverse.

### This library supports these functions. ###

 1. RAW read by image size of height, width automatically calculated and padded with Zero.

 1. Get weight informations to calculating window size.

 1. Windowing - threshold cut-off (for lose useless image datas, or make it easy to processing)

 1. CLAHE( Contrast Limited Adaptive Histogram Equalization )

 1. Export to 8bit pixel array(vector array)

 1. Export to 16bit pixel array(vector array)

 1. Reverse all pixels ( black to white, or white to black )

 1. Flip H/V and Rotate in 90,180,270 degrees.

 1. 2 different ways for tone mapping (known as H.D.R image)

### Makefile rule ###

 1. Refer to HOW2MAKE.

### And still these functions are not embodied. ###

 1. Nothing in now.

### Reserved to be included ###

* Nothing now, bug fix if found.

### Latest update ###

* Version marked as 0.9.35.150.

* Included byte swapping

### Previous updates ###

* Fixed some bugs in AdjustingXXX methods.

* Enhanced CLAHE region divider, no failure at running, but result may affected.

* Fixed getting version information.

* Added RotateFree, RotateFree in cropped for original image size.

* Changed method name Reverse() to Invert()

* Changed method name ReverseAuto() to InvertAuto()

* Fixed a bug of Rotate180()

* Added Low Frequency Filter (may used for removing artifacts)

* Added Edge Enhancement Filter

* Added Anistropic Filter

* Optimized CLAHE algorithm works.

* Included prototype of CLAHE, not optimized.

* Fixed wrong range threshold method.

* Fixed some issues

  1. Tone mapping divide & multiply fixed different range.

* Supporting 2 different methods of Hight Dynamic Range tone mapping with this methods:

  1. bool AdjustToneMapping();

* Now supporting openmp, compiler may need support this.

* Added ReverseAuto();

* Fixed a bug in resize to same image.

* Fixed a bug of AdjustGamma();

* Supports Gamma, Brightness, Contrast with these methods:

  1. bool AdjustGamma( float gamma );

  2. bool AdjustBrightness( float percent );

  3. bool AdjustContrast( float percent ); 

* Now supporting Pixel filterings with :

  1. ApplyFilter();

  2. CloneWithFilter();

* Basically provides these filters:

  1. blur

  2. blur more

  3. edge

  4. edge more

  5. sharpen

  6. sharpen more

  7. sharpen subtle

  8. unsharpen mask (in development)

* User customizable filter availed, see WIKI.

* Median filter included:

  1. ApplyMedianFilter();

* Enhanced for these methods:

  1. Get16bitThresholdedImage();

  1. Get8bitThresholdedImage();

* Changed some integer type to unsigned.

* Added function for Linear, Rectangle, Polygon regional histogram data.

  1. GetLinearPixels();

  1. GetRectPixels();

  1. GetPolygonPixels();

* Can getting information about average, variance, deviation from this method:

  1. GetAnalysisFromPixels();

* Fixed a bug Rescaled result applied again transform.

* Changed some method names:

  1. getWidth() -> Width()

  1. getHeight() -> Height()

  1. rescale() -> Rescale()

* Added method:

  1. SaveToFile()

* Reverse(Invert) all pixels with bit-range ( 9 to 16 )

* LoadingMatrix changed to Transform (unsigned int) definitions.

* Supporting these transforms :

  1. Flip horizontal.

  1. Flip vertical.

  1. Rotate clock wide 90,180,270

  1. Rotate reverse clock wide 90,180,270

* Included RAW image filtered scaling.

* Rescale method supports these: BiLinear/BiCubic/BSpline/Lanczos3

* Source refer to Free Image Project (http://freeimage.sourceforge.net/)

* Removed class methods not handles TCHAR casting.

* Compatible with 64bit gcc compilers.
