Hi everyone.

I'm Gianluca Gaggi, a member of the Msx Association for a few months.

In collaboration with Stefano Roperto and in agreement with Mega President Max, I am building a small TP library to easily create geometric figures in a graphical way.

As primitives (line/point) I'm using the ones provided to me by Stefano.

Today I noticed something.

As an emulator I use BlueMsx and using the Fill procedure (library provided with the Pascal starter pack by Stefano) I noticed a difference in behavior between the emulator and the real machine (I use a svi 728).

In BlueMsx the program crashes as soon as the Fill execution (basically the Paint of Basic) is finished. In SVI (fortunately...) this doesn't happen.

Is this the emulator's fault and is it fixable? Ultimately, it wouldn't be a big problem, but being able to do everything from a PC without having to always test on the real machine would be better.

For now I have created the basic geometric figures (triangles, rectangle (which also acts as a square), regular figures (pentagon facing up...) and above all the possibility of using a variable coordinate center (I can use the coordinates by specifying the position of the x-axis, y a priori).

Additionally, geometric figures can be rotated (except circles and ellipses).

The goal is to bring together many procedures that can stimulate the graphical use of TP and perhaps push towards the creation of a game made with this language.

If anyone has any suggestions/ideas, please let me know.

Later I will put the library and some documentation about it,

Thank you

Gianluca
