HOW2 simulate a keybrd-press ?

Question

We want to start: gpicview *jpg, and immediately switch to full-screen-mode; which is done by . But `man gpicview` says it has no options. And if the it would need be spawned by gpicview ?

Or is there a lightweight *.jpg to FrameBuffer utility? This is for an educational toy.

And also, would the following pseudo-code be suitable for cycling pictures with their matching audio? Write shell script to:-- FOR i := First TO Last DO DisplayJpg[i]; aplay $i.wav; killall //after aplay times-out ENDFOR ?

== TIA

Have a look at the example code in /opt/vc/src/hello_pi

Specifically the hello_jpeg code. This decodes and displays jpegs on the screen using the hardware, so will be fast.

Look at the README file first, you need to build the libaries, then build the program. It should take a minute or two in total, if you are up to that. No changes to any files required.

xmacroplay is very useful for that kind of thing. With a bit of scripting, it is possible to automate web login sequences or even printing both sides of a check on an online banking site.
