#define MATH_GET_STARTDELIMITER "Math/GetStartDelimiter"
// returns the delimiter that marks the beginning of a formula
// wparam=0
// lparam=0
// result=*char Delimiter
// !!! the result-buffer must be deleted with MTH_FREE_MATH_BUFFER

#define MATH_GETENDDELIMITER "Math/GetEndDelimiter"
// returns the delimiter that marks the end of a formula
// wparam=0
// lparam=0
// result=*char Delimiter
// !!! the result-buffer must be deleted with MTH_FREE_MATH_BUFFER

#define MTH_FREE_MATH_BUFFER "Math/FreeRTFBitmapText"
// deletes any buffer that MathModule has created.
// wparam=0
// lparam=(*char) buffer
// result=0

#define MATH_SETBKGCOLOR "Math/SetBackGroundColor"
// changes the background color of the next formula to be rendered.
// wparam=0
// lparam=(COLORREF) color
// result=0

#define MTH_GETBITMAP "Math/GetBitmap"
//returns Bitmap that represents the formula given in lparam (string-pointer)
//this formula has NO Delimiters.
//wparam=0
//lparam=(*char)Formula
//result=(HBITMAP) bitmap
//!!! the bitmap must be deleted with DeleteObject(hobject)

//example:
//HBITMAP Bmp=(HBITMAP)CallService(MTH_GETBITMAP,0, (LPARAM)formula);

#define MTH_GET_RTF_BITMAPTEXT "Math/GetRTFBitmapText"
// returns rich-text stream that includes bitmaps from text given in lparam
// text included between MATH_GET_STARTDELIMITER and MATH_GETENDDELIMITER
// hereby is replaced with a rtf-bitmap-stream that represents the corresponding formula
// wparam=0
// lparam=*char text
// result=*char rtfstream
// !!! the result-buffer must be deleted with MTH_FREE_RTF_BITMAPTEXT

#define MTH_FREE_RTF_BITMAPTEXT "Math/FreeRTFBitmapText"
// deletes the buffer that MTH_GET_RTF_BITMAPTEXT has created.
// wparam=0
// lparam=(*char) buffer
// result=0


// **************************************************************
// The following is still SRMM - specific.
// I plan to modify it, so that other PlugIns can take advantage of e.g. preview-window....

#define MTH_SHOW "Math/Show"
// shows the preview-window
// wparam=0
// lparam=0
// result=0

#define MTH_HIDE "Math/Hide"
// hides the preview-window
// wparam=0
// lparam=0
// result=0

#define MTH_RESIZE "Math/Resize"
// sets the size of the preview-window
// wparam=0
// lparam=(*TMathWindowInfo)
// result=0

#define MTH_SETFORMULA "Math/SetFormula"
// sets the text that the preview-window should parse to display formulas found inside
// wparam=0
// lparam=(*char) text
// result=0

#define MTH_Set_Srmm_HWND "Math/SetSrmmHWND" //übergibt fenster-Handle des aktuellen Message-Dialogs
// If MathModule knows the handle of a SRMM-based window, following features exist:
// - preview window resizes Math-Srmm when it is being resized.
// - Toolbox places text in the Send-Window of the SRMM-window
// wparam=0
// lparam=handle
// result=0

#define MTH_GET_PREVIEW_HEIGHT "Math/getPreviewHeight"
// returns the height of the whole preview-window (including system-menu-bar)
// consider this when maximizing a window to that preview-window is hooked on top or bottom
// it returns the height no matter whether preview-window is visible or not
// wparam=0
// lparam=0
// result=(int) height

#define MTH_GET_PREVIEW_SHOWN "Math/getPreviewShown"
// returns 1 if preview window is visible
// returns 0 if preview window is invisible
// result=(int) shown

#define MTH_SUBSTITUTE_DELIMITER "Math/SubstituteDelimiter"
// replaces Substitute given lparam-structure with internal Math-Delimiter
// wparam=0
// lparam=(TMathSubstInfo) substInfo
// result=0
