Send Switch Stat variables to JavaScript

[LasseThid]

Is it possible to somehow use the Stat.TrimboxWidth and Stat.TrimboxHeight variables in a JavaScript for use in a calculation?
I need to somehow calculate the width and height of a pdf in millimeters without decimals and then send the result back to switch.

Hello,

You don't need necessarily use Javascript.
You may use the built-in functions "Calculation"



Best regards,

Code: Select all

var width = job.getVariableAsNumber("[Stat.TrimboxWidth]"); 
var height = job.getVariableAsNumber("[Stat.TrimboxHeight]");

The problem with the Switch Calculation is that you get atleast one decimal and HP SmartStream Designer Imposition is not able to import an imposition containing a . in the file name, i.e. 90.0x55.0 is seen by SmartStream designer as 90 .

The way to get around it would be to divide the result by 10 with one decimal and then multiply by 10, but I'm not sure if that will do they job.

With JavaScript I can use .floor and get rid of the decimals in the calculation.

var width = job.getVariableAsNumber("[Stat.TrimboxWidth]"); 
var height = job.getVariableAsNumber("[Stat.TrimboxHeight]"); 

Thank you very much.

You can use Round() in Switch Calculation variables.

Thanks Andrea.
That's may make life a bit easier for me.

Update:
I can't figure out how to use Round() in my calculation.
[Switch.Calculation:Expression="Round([Stats.TrimBoxWidth]/72*25.4)"] results in the value 0 instead of the expected 90.

[MoodyBro]

Code: Select all

Round([Switch.Calculation:Expression="[Stats.TrimBoxWidth]/2.83464"])

You could also use a script-expression so you can log your parameters:

Code: Select all

var width = Math.round(job.getVariableAsNumber("[Stats.TrimBoxWidth]")/2.83464);
job.log(2,"Width: %1", width);

width;

Thanks to everyone for helping me out.

Script is done now and working as expected.

@MoodyBro:
As I'm just starting to learn scripting I'm a bit curious about the log thing.
Can you expand on how it's working and how to use it, either here or in a PM?

Thanks
Lasse

The "Log" are just the messages in Switch
You are able to write into these messages with "job.log":

Code: Select all

job.log(1,"Hello world!");

The number "1" ist the message-type, so you are able to write Error-, Warning- oder just normal Info-Messages.

1 | Info (black)
2 | Warning (yellow)
3 | Error (red)

You can also write some variable-informations into your "log":

Code: Select all

// myFile = "flyer_2015.pdf";
job.log(3,"The process for file %1 doesn't work!", myFile);
// This will write a red text into your log: "The process for file flyer_2015.pdf doesn't work!"


// you can also use more than just one variable
job.log(2,"FirstVariable = %11, SecondVariable = %12", [firstVar, secondVar]);

Thanks for the explanation MoodyBro.

I will look into that next time I'm working on a script.
