|

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
