PERTAIN_TOProblem

The Crystal portion must run on Windows under .NET Framework. — in a Windows Form to react (Core web API) conversion project. Tension: Can't use .NET Core. Outcome: So highest you can go is 4.8.1.

PERTAIN_TOSolution

there are 3rd-party Crystal Reports automation packages — If you don't want to develop the Crystal portion yourself. Tension: provide a command line API. Outcome: that provide a command line API.

PERTAIN_TOSolution

Your main app can call the Crystal app, pass the rpt file path, parameters, logon info, export format, export file, etc. — Your main app. Outcome: It can then deliver the exported file to the end user.

PERTAIN_TOProblem

The issue I am seeing is that the resolution decreases significantly during this process. — The program converts the PDF to JPG, performs the "slicing" action, then converts it back to PDF for printing. Tension: I did some research and saw that the PDFBox tools is able to set the DPI of the JPG during conversion from PDF, which I did using some code from AI, however it did not help the resolution. Outcome: My son said to convert to PNG which is lossless and, again I had AI write me some code which also didn't seem to work.

PERTAIN_TOSolution

There is a cross-platform multi-language PDF API (C, C#, CSS, Python, JavaScript, but not yet Java ?) that is well suited to this task. — Here I am simply using OS command lines with the prebuilt binary. Tension: Unlike many other methods the output PDF file size should be only slightly larger than the input PDF. Outcome: cpdf -chop-v 866 in.pdf -o 2bits.pdf & cpdf -chop-v 2598 2bits.pdf 2 -o 3bits.pdf.
