- * miGIF compression uses run length encoding. It compresses horizontal runs

- * of pixels of the same color. This type of compression gives good results

- * on images with many runs, for example images with lines, text and solid

- * shapes on a solid-colored background. It gives little or no compression

- * 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)

- * This method is similar to GetPixelColorInterpolated, but this method also properly handles

- * subsampling.

- * If you need to sample original image with interval of more than 1 pixel (as when shrinking an image),

- * you should use this method instead of GetPixelColorInterpolated or aliasing will occur.

- * When area width and height are both less than pixel, this method gets pixel color by interpolating

- * color of frame center with selected (inMethod) interpolation by calling GetPixelColorInterpolated.

- * If width and height are more than 1, method calculates color by averaging color of pixels within area.

- * Interpolation method is not used in this case. Pixel color is interpolated by averaging instead.

- * If only one of both is more than 1, method uses combination of interpolation and averaging.

- * Chosen interpolation method is used, but since it is averaged later on, there is little difference

- * between IM_BILINEAR (perhaps best for this case) and better methods. IM_NEAREST_NEIGHBOUR again

- * leads to aliasing artifacts.

- * This method is a bit slower than GetPixelColorInterpolated and when aliasing is not a problem, you should

- * simply use the later.

- *

- * 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))

-

-	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.

-	Notes by Author:

-*********************************************************************

-

-	Limitations:

-	============

-

-	a) Transparency:

-

-	A Metafile is vector graphics, which has transparency by design.

-	This class always converts into	a Bitmap format. Transparency is

-	supported, but there is no good way to find out, which parts

-	of the Metafile are transparent. There are two ways how we can

-	handle this:

-

-	- Clear the Background of the Bitmap with the background color

-	  you like (i have used COLOR_WINDOW) and don't support transparency.

-

-	  below #define XMF_SUPPORT_TRANSPARENCY 0

-			#define XMF_COLOR_BACK RGB(Background color you like)

-

-	- Clear the Background of the Bitmap with a very unusual color

-	  (which one ?) and use this color as the transparent color

-

-	  below #define XMF_SUPPORT_TRANSPARENCY 1

-			#define	XMF_COLOR_TRANSPARENT_R ...

-			#define	XMF_COLOR_TRANSPARENT_G	...

-			#define	XMF_COLOR_TRANSPARENT_B	...

-

-	b) Resolution

-

-	Once we have converted the Metafile into a Bitmap and we zoom in

-	or out, the image may not look very good. If we still had the

-	original Metafile, zooming would produce good results always.

-

-	c) Size

-

-	Although the filesize of a Metafile may be very small, it might

-	produce a Bitmap with a bombastic size. Assume you have a Metafile

-	with an image size of 6000*4000, which contains just one Metafile

-	record ((e.g. a line from (0,0) to (6000, 4000)). The filesize

-	of this Metafile would be let's say 100kB. If we convert it to

-	a 6000*4000 Bitmap with 24 Bits/Pixes, the Bitmap would consume

-	about 68MB of memory.

-

-	I have choosen, to limit the size of the Bitmap to max.

-	screensize, to avoid memory problems.

-

-	If you want something else,

-	modify #define XMF_MAXSIZE_CX / XMF_MAXSIZE_CY below
