It's something from the old ptp liveview code, it will go away.

This is not so good. Since we have cameras with different screen width and lua drawing & console comands it would be useful to have a command for determination of screen width.

Textbox added.

[offtopic]

When I was writing the lua drawings I tried to provide such lua commands like draw_get_width() and draw_get_height() but I had no idea how to do so. It would be very nice.

AFAIR I tried to just return the values of camera_screen.width and camera_screen.height (as in gui_draw.c) but they gave strange values. Now I can't recall what it was.

The idea was:

Code: (c) [Select]
static int luaCB_draw_get_width( lua_State* L )
{
  lua_pushnumber( L, camera_screen.width );
  return 1;
}

static int luaCB_draw_get_height( lua_State* L )
{
  lua_pushnumber( L, camera_screen.height );
  return 1;
}


With such functions there could be constant values defined in drawings.lua modules for convenient usage:

Code: (lua) [Select]
WIDTH=draw_get_width()
HEIGHT=draw_get_height()

That's fine, but it should not be this function, because what it returns is not very useful for lua.

Maybe a moderator can split this discussion ?

Or to make things easy - just start another thread on "Scripting function to report display sizes" ?

Select/case?
« Reply #15 on: 29 / May / 2012, 09:49:29 »
Skywalker9's Selective Intervalometer script uses select/case/end_select, but I can't find that in the cross reference or any other documentation.  Am I missing something?
