Scale to Fit spreadsheet to one Page

Post by rkwolf0211 »

Trying to find the right combination to scale a spreadsheet to one page.

I have inherited this code that was referencing the following BNDDIR and /copy statements.

H BNDDIR('HSSF')
* Load JAVA Routines
/copy hssf_h

I am trying the following statements, with program dump results. So doing something wrong.

SSPrintSetup_setFitHeight( sheet:1);
SSPrintSetup_setFitWidth( sheet:1);

Any and all help would be appreciated.

These routines work on the PrintSetup class. You are passing an object called 'sheet', which I'm guessing is a Sheet class rather than a PrintSetup class...

I apologize, it has been FOREVER (more than 10 years) since I've worked with this stuff. In my prior job, I ended up building our own spreadsheet creation code because POI was too slow. Then, I changed jobs, and have not used it since... so it's been a REALLY long time.

From another example I found online, I cobbled something together thatt seems to work. I apologize that the H/D specs are still in fixed-format, but I'm super, super busy right now and did not have time to convert the old code to free format. Give this a try:

Code: Select all

     H DFTACTGRP(*NO) BNDDIR('HSSF')

      /copy hssf_h

     D SSSheet_setFitToPage...
     D                 PR                  ExtProc(*JAVA
     D                                     : SHEET_CLASS
     D                                     : 'setFitToPage')
     D   fitToPage                    1N   value

     D book            s                   like(SSWorkbook)
     D text            s                   like(SSCellStyle)
     D sheet           s                   like(SSSheet)
     D row             s                   like(SSRow)
     D ps              s                   like(SSPrintSetup)

      /free
           ss_begin_object_group(100);

          // Create a new workbook

           book = new_XSSFWorkbook();

           Text = SSWorkbook_createCellStyle(book);

          // Create a sheet named 'Test' containing 1 cell
          //  with some test data in it.

           sheet = ss_newSheet(book: 'Test');
           row = SSSheet_createRow(sheet: 1);
           ss_text( row: 1: 'Testing Page Fit': Text);

          //  Set up autofit

           SSSheet_setFitToPage(sheet: *ON);
           ps = SSSheet_getPrintSetup(sheet);
           SSPrintSetup_setFitWidth(ps: 1);
           SSPrintSetup_setFitHeight(ps: 1);

          //  Write it to disk

           SS_save(book: '/tmp/scale_fit.xlsx');
           ss_end_object_group();

           *inlr = *on;
      /end-free

Adding to my last post.. I did not actually print it, but when I go to the 'Print' screen within Excel, I see this:
printSettings.png
printSettings.png (14.42 KiB) Viewed 18461 times
And if I click "Page Setup" from there, I see this:
pageSetup.png
pageSetup.png (16.46 KiB) Viewed 18461 times
So, it looks to me like the program set these correctly.

Okay, I copied your code. Got your copy compiled and ran with huge success.

Now trying to merge into my existing code.

getting RNF5406 - The call passed fewer parameters than the prototype indicates
are required.

I understand you are very busy, I am working through and researching what the difference would be.

That's a normal RPG compile error -- has nothing to do with HSSFR4. It just means you aren't passing all of the parameters required to a given prototype.

Look at the compile listing and see where the error is occuring. Examine that line, and determine which parameter you are missing. Fix the bug.

Well, been trying to get this to work. Moved code to be before the SaveSheet(book);
Debugged, see the code being executed.

I am saving the spreadsheet as a XLS, thought that may be the issue. so change to XLSX, to match the provided code.

Just not having any luck.

moved the fittopage
to the SS_save in my code, still not working:

1994.00 // >> Set up autofit
1995.00
1996.00 SSSheet_setFitToPage(sheet: *ON);
1997.00 ps = SSSheet_getPrintSetup(sheet);
1998.00 SSPrintSetup_setFitWidth(ps: 1);
1999.00 SSPrintSetup_setFitHeight(ps: 1);
2000.00 // >>
2001.00 ss_save(books:IFSDIRS);
2002.00 /end-free
2003.00 P E
