Hallo again!
okay, I implemented now the stuff for pix_buffer_read and it performs much much better (as fast as pix_image).
the changes:
o) check for new buffer: at start rendering and if the buffer is changed with a message
o) check for new image in the buffer: at start rendering, when buffer changes, when index changes, in auto-change-mode every frame of course
The only situation, where the behaviour differs is, when a new image is loaded into a buffer - so you would have to retrigger the index now - is that okay?
The new files are attached - if they are accepted I will also update the help patches ...
LG Georg
