- * (this is the point: in order to avoid transgression of the Unisys patent
- * on the LZW algorithm.) However, miGIF generates data streams that any
- * reasonably sane LZW decompresser will decompress to what we want.
- *
- * 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
- * on images with few runs, for example digital or scanned photos.

-/**
- * 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)

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

- * 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.

- Note by Author:
-*********************************************************************
-
- 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: see ximawmf.h
- you may configure some stuff there

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