Hello, Alexei and All:
I am very glad, you replied so quickly.
Here is some my advices:
1. Flip font image is very easy. To add this function, someone should research whole code, and give a good resolution.
First, it need to transfer a parameter from caller to indicate.
2. I had sent some sourcodes like bitmap italic(two years), line thickness(this year). And I didn't receive a reply like it's
good or bad.
3. I suggest that we make a plan, to add those features step by step. I will do it as your mean on sourcecode, to make it
easy. Include:
Rotate for 4directions.
Italic
New bold algorithm.
Gray bold.
I really love freetype very much, so I want to make it more powerful and.
Waiting for your plan.

主 题：Re: This is freetype sourcecode from TSIT(I made many improvements)
Those improvements include:
Outline:
italic for any value.
line thickness.
Bitmap:
Rotate for 4 directions.
Italic. Three type: clockwise, counter-clockwise, top to bottom(chinese chars needthis feature).
Bold. We use a new algorithm.
Gray Bold. If all pixels use black color, some chinese chars are very ugly. So I developed a gray bold to make them very beautiful.
Filp. Left to right, and top to bottom.
Some of these changes alter API by renaming. This is Not acceptable. Other changes are trivial special cases: flip, turn. This is trivial and not interesting to general public. An intelligent user can easily implement this.
If you want us to consider the bitmap emboldening algorithms, which you claim as novel, please present them separately from the rest. And explain them very carefully.
