Script to export worksheets properly to pdf.

Recommended Posts

We all know we can't export worksheet properly to PDF due to the page print setting that doesn't work. I've always wanted to export X sheets on a chosen paper size, mostly A4.

Instead of creating an Sheet Layer for each worksheet, with a manual made viewport that scales it down until it fits you can use this script to do that for you. It only needs one Sheetlayer for all of your worksheets btw.

This script works pretty easy

- choose a layername where an image of the ws will be stored.

- Setup and choose a sheetlayer with the page size, sheet border and title block you want. Make sure the page is not moved.

Loop this script for each worksheet you need within the export pdf script and there you go. Never need to make a viewport again to scale any worksheet !

This is pretty basic and might not work for each type and position of titleblock, it can also only scale down but it can be tweaked into anything. It reads the sheet border frame dimensions and margins and will place and scale the viewport where it belongs. There is an option to shift the viewport to the bottom / top.

Batchprint all the way !

PROCEDURE CreateWsViewport(LayerName,DesignLayerName,SheetName	:STRING; VAR FrameHd	:HANDLE);
	VAR
		PrintLayerHd,ViewportHd,SheetHd,SheetImageHd, LayerHd	:HANDLE;
		result,MoveToTop,MoveToBottom,IsTitleBlock_B,IsTitleBlock_T	:BOOLEAN;

	BEGIN

		{ Delete the previous viewport incase this script is looped ? }
		IF GetObject(ViewportName) <> NIL THEN DelObject(GetObject(ViewportName));

Working example how I implemented it making one pdf of A4 pages containing 3 types of unlimited worksheets:
