How to split one long page into multiple pages?

Hi,

Here is an adaptation of a script I wrote some times ago:

var theFormat=["US Letter",612,792,"–",612,792*3];
var nbPages=this.numPages;
for (var p=0; p<nbPages; p++) {
	this.newPage(p+nbPages,theFormat[4],theFormat[5]);
	this.addWatermarkFromFile({
		cDIPath: this.path,
		nSourcePage: p,
		nStart: p+nbPages,
		nScale: -1,
	});
}
this.deletePages(0,nbPages-1);
var thePath=this.path.replace(/.pdf$/i," (Splited in "+theFormat[0]+" Format).pdf");
this.saveAs({
	cPath: thePath,
	bCopy: true,
});
for (var p=0; p<nbPages; p++) {
	for (i=0; i<3; i++) {
		this.newPage(p+nbPages+i,theFormat[1],theFormat[2]);
		this.addWatermarkFromFile({
			cDIPath: thePath,
			nSourcePage: p,
			nStart: p+nbPages+i,
			nVertAlign: app.constants.align.top,
			nVertValue: theFormat[2]*i,
		});
	}
}
this.deletePages(0,nbPages-1);
this.saveAs({cPath: thePath});

Copy this script in the empt console window, then select all the text and press the ENTER key of the numerical panel.

That should fit your scan in a 3-page US letter sheet format.
