You have a very long rendering....

Have a look at the rendering window. The number of pages per second is a good performance indicator.

 

If you don't see this window or if the number of pages per second is less than ~20, YOU HAVE A PROBLEM!

 

 

With large files, vpxPrint crashes or hangs after a while, with light files the rendering of files is very long, why ?

 

You need to know that  vpxPrint processes files, line  by line.

 

On another terms, vpxPrint reads one line (delimiter is cr-lf or lf) and processes each tag. When a tag is processed, the line is shifted on the left.

 

If your file does not contain line skips,  then the entire file is shifted on each tag ! 

 

You can easily add SKIP each time that you have a sequence <Rxxxx><Cxxxxx> ot <AT> tag with absolute references (<R1><C10> ot <AT=10,20>).

 

Add line skips and the rendering will be done very quickly instead of the poor performance.

 

If your program is difficult to change, insert the following non-destructive code :

        PUT UNFORMATTED "<#500>" skip "<=500>".

on a regular basis.

 

Consider using the <BACKGROUND> tag. The background will be rendered only one time. That is less memory and time consuming. and time consuming.
