- 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
