Auto Zoom Script

I think this is a scripting issue, but I'm not 100% sure.

I have a Canon Powershot A2400 with CHDK loaded on it.  Everything appears normal there.  What I want to do is to have my camera zoom to a specific spot every time I turn on the camera.  Is that done through scripts?  If so, can you give me a rundown of the steps I need to go through to get this done?

Thank you much!

You can configure a CHDK script to run each time the camera starts.  The option to do that is in the CHDK scripting menu.

What you then need is a small script that pauses for a couple of seconds to let the camera get all setup,  and then issues a set_zoom()  command.

You can make the zoom position a fixed value in the script, or use the @parameter script construct to allow you to specific the zoom position that will be used at subsequent startups.

Let me know if you need help writing the script.

Found this in my collection - should do the job.

I just loaded up the script you attached and it's perfect!  Works beautifully.  Thank you both so much!

Cut & pasted the code here - sometime forum attachments get lost during upgrades & server migration.

--[[
@title Zoom Preset
  @param   z Zoom (%)
  @default z 0
  @range   z 0 100

set_console_layout(1 ,1, 45, 14 )
sleep(2000)
if ( get_mode() == false ) then set_record(1)
    while ( get_mode() == false ) do sleep(100) end
end
zstep=((get_zoom_steps()-1)*z)/100
print("Setting zoom to "..z.." percent. Step="..zstep)
sleep(500)
set_zoom(z)
sleep(1000)
exit_alt()
