-*\r
-* \brief This filter computes one-pixel-wide skeleton of a 3D input image.\r
-*\r
-* This class is parametrized over the type of the input image\r
-* and the type of the output image.\r
-* \r
-* The input is assumed to be a binary image. All non-zero valued voxels\r
-* are set to 1 internally to simplify the computation. The filter will\r
-* produce a skeleton of the object. The output background values are 0,\r
-* and the foreground values are 1.\r
-* \r
-* A 26-neighbourhood configuration is used for the foreground and a\r
-* 6-neighbourhood configuration for the background. Thinning is performed\r
-* symmetrically in order to guarantee that the skeleton lies medial within\r
-* the object.\r
-*\r
-* This filter is a parallel thinning algorithm and is an implementation\r
-* of the algorithm described in:\r
-* \r
-* T.C. Lee, R.L. Kashyap, and C.N. Chu.\r
-* Building skeleton models via 3-D medial surface/axis thinning algorithms.\r
-* Computer Vision, Graphics, and Image Processing, 56(6):462--478, 1994.\r

- * If you need to sample original image with interval of more than 1 pixel (as when shrinking an image), \r
- * you should use this method instead of GetPixelColorInterpolated or aliasing will occur.\r
- * When area width and height are both less than pixel, this method gets pixel color by interpolating\r
- * color of frame center with selected (inMethod) interpolation by calling GetPixelColorInterpolated. \r
- * If width and height are more than 1, method calculates color by averaging color of pixels within area.\r
- * Interpolation method is not used in this case. Pixel color is interpolated by averaging instead.\r
- * If only one of both is more than 1, method uses combination of interpolation and averaging.\r
- * Chosen interpolation method is used, but since it is averaged later on, there is little difference\r
- * between IM_BILINEAR (perhaps best for this case) and better methods. IM_NEAREST_NEIGHBOUR again\r
- * leads to aliasing artifacts.\r

+/**
+ * This method reconstructs image according to chosen interpolation method and then returns pixel (x,y).
+ * (x,y) can lie between actual image pixels. If (x,y) lies outside of image, method returns value
+ * according to overflow method.
+ * This method is very useful for geometrical image transformations, where destination pixel
+ * can often assume color value lying between source pixels.
+ *
+ * \param (x,y) - coordinates of pixel to return
+ * GPCI method recreates "analogue" image back from digital data, so x and y
+ * are float values and color value of point (1.1,1) will generally not be same
+ * as (1,1). Center of first pixel is at (0,0) and center of pixel right to it is (1,0).
+ * (0.5,0) is half way between these two pixels.
+ * \param inMethod - interpolation (reconstruction) method (kernel) to use:
+ * - IM_NEAREST_NEIGHBOUR - returns colour of nearest lying pixel (causes stairy look of
+ * processed images)
+ * - IM_BILINEAR - interpolates colour from four neighbouring pixels (softens image a bit)
+ * - IM_BICUBIC - interpolates from 16 neighbouring pixels (can produce "halo" artifacts)
+ * - IM_BICUBIC2 - interpolates from 16 neighbouring pixels (perhaps a bit less halo artifacts
+ than IM_BICUBIC)
+ * - IM_BSPLINE - interpolates from 16 neighbouring pixels (softens image, washes colours)
+ * (As far as I know, image should be prefiltered for this method to give
+ * good results... some other time :) )
+ * This method uses bicubic interpolation kernel from CXImage 5.99a and older
+ * versions.
+ * - IM_LANCZOS - interpolates from 12*12 pixels (slow, ringing artifacts)
+ *
+ * \param ofMethod - overflow method (see comments at GetPixelColorWithOverflow)
+ * \param rplColor - pointer to color used for out of borders pixels in OM_COLOR mode
+ * (and other modes if colour can't calculated in a specified way)
+ *
+ * \return interpolated color value (including interpolated alpha value, if image has alpha layer)

+ * Faster way to almost properly shrink image. Algorithm produces results comparable with "high resoultion shrink"
+ * when resulting image is much smaller (that would be 3 times or more) than original. When
+ * resulting image is only slightly smaller, results are closer to nearest pixel.
+ * This algorithm works by averaging, but it does not calculate fractions of pixels. It adds whole
+ * source pixels to the best destionation. It is not geometrically "correct".
+ * It's main advantage over "high" resulution shrink is speed, so it's useful, when speed is most
+ * important (preview thumbnails, "map" view, ...).
+ * Method is optimized for RGB24 images.
+ *
+ * \param newx, newy - size of destination image (must be smaller than original!)
+ * \param iDst - pointer to destination image (if it's 0, this image is modified)
+ * \param bChangeBpp - flag points to change result image bpp (if it's true, this result image bpp = 24 (useful for B/W image thumbnails))
+ *
+ * \return true if everything is ok

-\r
- Metafile Formats:\r
- =================\r
-\r
- There are 2 kinds of Windows Metafiles:\r
- - Standard Windows Metafile\r
- - Placeable Windows Metafile\r
-\r
- A StandardWindows Metafile looks like:\r
- - Metafile Header (MEATAHEADER)\r
- - Metafile Records \r
-\r
- A Placeable Metafile looks like:\r
- - Aldus Header (METAFILEHEADER)\r
- - Metafile Header (METAHEADER)\r
- - Metafile Records\r
-\r
- The "Metafile Header" and the "Metafile Records" are the same\r
- for both formats. However, the Standard Metafile does not contain any\r
- information about the original dimensions or x/y ratio of the Metafile.\r
-\r
- I decided, to allow only placeable Metafiles here. If you also want to\r
- enable Standard Metafiles, you will have to guess the dimensions of\r
- the image.\r

+*********************************************************************
+
+ Metafile Formats:
+ =================
+
+ There are 2 kinds of Windows Metafiles:
+ - Standard Windows Metafile
+ - Placeable Windows Metafile
+
+ A StandardWindows Metafile looks like:
+ - Metafile Header (MEATAHEADER)
+ - Metafile Records
+
+ A Placeable Metafile looks like:
+ - Aldus Header (METAFILEHEADER)
+ - Metafile Header (METAHEADER)
+ - Metafile Records
+
+ The "Metafile Header" and the "Metafile Records" are the same
+ for both formats. However, the Standard Metafile does not contain any
+ information about the original dimensions or x/y ratio of the Metafile.
+
+ I decided, to allow only placeable Metafiles here. If you also want to
+ enable Standard Metafiles, you will have to guess the dimensions of
+ the image.
+

- Limitations:\r
- ============\r
-\r
- a) Transparency:\r
-\r
- A Metafile is vector graphics, which has transparency by design.\r
- This class always converts into a Bitmap format. Transparency is\r
- supported, but there is no good way to find out, which parts\r
- of the Metafile are transparent. There are two ways how we can\r
- handle this:\r
-\r
- - Clear the Background of the Bitmap with the background color\r
- you like (i have used COLOR_WINDOW) and don't support transparency.\r
-\r
- below #define XMF_SUPPORT_TRANSPARENCY 0\r
- #define XMF_COLOR_BACK RGB(Background color you like)\r
-\r
- - Clear the Background of the Bitmap with a very unusual color\r
- (which one ?) and use this color as the transparent color\r
-\r
- below #define XMF_SUPPORT_TRANSPARENCY 1\r
- #define XMF_COLOR_TRANSPARENT_R ...\r
- #define XMF_COLOR_TRANSPARENT_G ...\r
- #define XMF_COLOR_TRANSPARENT_B ...\r
-\r
- b) Resolution\r
-\r
- Once we have converted the Metafile into a Bitmap and we zoom in\r
- or out, the image may not look very good. If we still had the\r
- original Metafile, zooming would produce good results always.\r
-\r
- c) Size\r
-\r
- Although the filesize of a Metafile may be very small, it might\r
- produce a Bitmap with a bombastic size. Assume you have a Metafile\r
- with an image size of 6000*4000, which contains just one Metafile\r
- record ((e.g. a line from (0,0) to (6000, 4000)). The filesize\r
- of this Metafile would be let's say 100kB. If we convert it to\r
- a 6000*4000 Bitmap with 24 Bits/Pixes, the Bitmap would consume\r
- about 68MB of memory.\r
-\r
- I have choosen, to limit the size of the Bitmap to max.\r
- screensize, to avoid memory problems.\r
-\r
- If you want something else,\r
- modify #define XMF_MAXSIZE_CX / XMF_MAXSIZE_CY below\r
