+// If this DLL is dynamically linked against the MFC\r
+// DLLs, any functions exported from this DLL which\r
+// call into MFC must have the AFX_MANAGE_STATE macro\r
+// added at the very beginning of the function.\r
+//\r
+// For example:\r
+//\r
+// extern "C" BOOL PASCAL EXPORT ExportedFunction()\r
+// {\r
+// AFX_MANAGE_STATE(AfxGetStaticModuleState());\r
+// // normal function body here\r
+// }\r
+//\r
+// It is very important that this macro appear in each\r
+// function, prior to any calls into MFC. This means that\r
+// it must appear as the first statement within the \r
+// function, even before any object variable declarations\r
+// as their constructors may generate calls into the MFC\r
+// DLL.\r
+//\r
+// Please see MFC Technical Notes 33 and 58 for additional\r
+// details.\r

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

+\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

+\r
+ 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
