问题 I have two pdf files of the same length, let's say pdf1.pdf and pdf2.pdf. I'm trying to watermark each page of pdf1.pdf with pdf2.pdf (i.e., page 1 of pdf1.pdf with page 1 of pdf2.pdf, page 2 of pdf1.pdf with page 2 of pdf2.pdf ...).

Crystal Reports 11 - Useless blank page is added with just group headers that have data

由 与世无争的帅哥 提交于 2020-08-08 05:53:48
问题 I have a weird problem I have never seen before using Crystal Reports. I built a complex PDF monthly report for a bank that generates over 200 pages.

But for some reason the report inserts quasi-blank pages rarely and seemingly randomly before it shows data. These pages aren't entirely blank, all my headers including group
