Title: Save to picture
Post by: Electricity440 on March 11, 2013, 10:42:37 am

On axe parser, how can I save the current screen to an external picture (pic0-9). I am just beginning in axe and I'm making a little draw program and I want them to be able to view it outside of the program.
Thanks

Here's how you could save the contents of the screen buffer to Pic0, following the general recipe for saving data to an OS variable:

Code: [Select]

GetCalc("Pic0",768)→P
!If P
.Could not create picture (not enough RAM), handle error here
Else
Copy(L₆,P,768)
End

Thanks, so how would you open one and show it to the screen?

Well, the exact opposite (if appvars and pics work the same) ;)

Code: [Select]

GetCalc("Pic0")→P
!If P
.Picture doesn't exist or is archived, handle error here
Else
Copy(P,L₆,768)
End

If the picture is archived, this should work:

Code: [Select]

GetCalc("Pic0",Y₀)→P
!If P
.Picture doesn't exist, handle error here
Else
Copy(Y₀,L₆,768)
End
