[Scilab-users] Video Player in Scilab

[Philipp Mühlmann]

Hi,

I suppose you always excange the current data of the already existing
Matplot with new Frame data?

Otherwise you would add a axis-children each time you excecute "Matplot
"..hence for each frame.

This will make you function become very slow after short time.

you can check with:

a = gca()
a.children

a.children should have only one entry.

I had this behaviour as described above building a GUI for scolling through
a set of Images.

My work around:

- create an empty Matplot first.

- At the real displaying of data I only exchange the "matplot.data" such
as:    a.children.data. = new_image;


Greetings,
Philipp
