Modify C++ project (a TrueType converter DLL)

This project is only for people who understand the task, questions welcome.

We will hand out the existing source only by request with NDA contract.


We have a well written source code in C++, which creates a DLL for use in a VB6 program.

It is coded using VC2010 and compiles fine.

Comments are in English language.

The now given functionality is:

The DLL creates a DXF file containing the glyph data of TrueType from a RTF string.

The result can be read in any CAD software.

As known, the glyphs of TrueType fonts are always closed.

Now the complete glyph data is written to the DXF file as splines.

All this works as expected and error free.

What is needed?

The now given functionality must be preserved and extended.

We now want a determined count of last pieces of a closed loop skipped (usually 1 to 3).

I.e. if a glyph results in 14 pieces, and we want the last 3 pieces skipped, the result is the first 11 pieces in the DXF file.

In case the skip count is larger than the count of existing pieces, it may not give a runtime error.

Instead only as many as possible has to be skipped.

In the existing DXF output, there is a routine that breaks a single spline into line pieces.

The above described logic has to skip the last spline before the spline-to-line conversion.

This all has to be optional and has to be an additional parameter in the DLL call.


It must be possible to compile the source with VC2010 Express with no errors.

It is not allowed to use our source code in other projects, and it is also not allowed to sell it to other parties.

We are always open for discussion and proposals.

If problems or question occur, we want to know as soon as possible.

Payment will happen immediately after testing on our side gives positive results.

Payment will happen in one shot only after completion, no intermediate milestones.

We need an invoice.
