Memory Game with Jasper Studio - Problems to create the "background side"

diegoqueres81 · May 7, 2019

I'm developing prototypes of memory games on Jasper Studio.

I would like to generate a report with the following structure:

Page 1: Images and labels of the cards;

Page 2: Background side of the cards on page 1;

Page 3: Images and labels of the cards;

Page 4: Background side of the cards on page 3;

...........................................................................................

A random example:

Printing the report, each page must have printed in both sides.

Front side of page: cards with images and texts

Back side of page: background of the memory cards

I want generate pdf reports that users will print first page, turn the paper in printer, and then they will print the back of the sheet with the background of the cards.

I was able to generate the cards already. But generating the background of the cards on the next sheet, I'm having troubles yet.

Anyone can help?

Have you tried putting each page as a subreport and putting a page break in between?

diegoqueres81 · May 9, 2019

I tried it now. The first page appears normal, the cover of the cards. but on the following pages, both subreports content overflow each other...

What i do to avoid this?

subreport 1 (cover)
break
subreport 2 (back)
break

have you set the POSITIONTYPE of the second subreport element and also the break-elements to FLOAT? Or is it still "FixRelativeToTop"? If so, just change it to "FLOAT".

If you put the second break behind the second subreport element, you always will get an empty page at the end, as the report won't know that the records are consumed/finished... so I guess, this isn't wanted.

actually I think, you wouldn't need a break element at all, as you also could use "RunToBottom" flag on both subReports - of course depending on your structure... so the first one will render your first cards and consume all the page height. now the second one will render your background elements, also consuming all the available page height, and so on... just give it a try.

Unfortunately I can't look at my "alternate duplex background sample", as this was done for a customer at my old company that was printing his general terms always on background of odd pages :-(

I tried your suggestions, C-Box.

Now it's showing all pages of the first subreport. and after that, displays all the pages of the second subreport.
It's close of what I want, but what I want is similar about you described: a page with the front of the cards, the next page with the background of the cards, and so on.

I tried of this way now:

subreport 1 (cover)
break
subreport 2 (back)

Detail band code:

I have tried without break element, and i get the same result.

Well I tried to remind what I've done some years ago for customer... as I said, I can't access the orginal jrxml as I changed the company.

So take a look at the sample attached. Run the Main Report with e.g. 27 empty records (so I used just an empty datasource for testing). The BackSide SubReport is also hardcoded with 9 emtpy records.. but I think you will manage to adapt it to your report/data ;-)

I followed your model. And it helped me a lot, thank you!

I made some improvements and adjusted to my cards.

Two parameters to improve control

I create two parameters to have some control over subreports:

CARDS_BY_COLUMN because, in some cases, i will want print 1 or 2 cards by column (i will do more than one game).

Page Header

Config summary to report

I have configured two properties on Jasper Report tag

isSummaryNewPage="true"

isSummaryWithPageHeaderAndFooter="true"

On subreport, i limit the records who will be showed (avoid overflow more than one page - on page header)

So.. I have to improve more, after tests: how it is showing with one page of cards, with cards filling more or less lines, ...

But in some tests it's already working as I expected.

Thank you very much!
