After updating from Clarion 9.1 to Clarion 11.1, saving to a PDF is extremely slow. A 50-page report (without images) takes about 4 minutes. Does anyone have an idea what might be causing this? Regards, Henk

Yes, if you are using the SV ReportToPdf global extension then you can select the engine there. Worth doing.

Henk, Have you checked and cleaned your temp folder?

Temp folder almost empty and I don’t think it has anything to do with deleting the WMF files. What I do is the following: I generate the report in a preview. Then I save it as a PDF (takes a long time). The preview is still on the screen. Then I close the preview. And that goes quickly. Another thi…

I thought I had read somewhere that there’s a different (better) PDF engine that someone from the community contributed to SV. I wonder if there’s a place that you have to specify it. If I am steering you to look in the wrong place, I pre-pologize to you. But I don’t see any other suggestions yet. I…

The PDFs generated by the built-in report target class are bloated and very large. You can programmatically print to PDF on disk with Microsoft Print to PDF printer driver. Use PRINTER{PROPPRINT:printtoname} to assign the file name. It is faster and generates smaller PDF files. You do need to wa…

It is amazing. I switched from “Clarion” to “Image2PDF”. The same report is now saved in 2 seconds. And the file size has been reduced to 179kB. Thanks a lot Bruce.

One thing to remember with Image2PDF is the generated PDF text isn’t searchable or selectable. Each page is an embedded image.

I dont think thats accurate Rick. (I’ll check later if im near a PC). The option to save the PDF as text, or a single image, is a different option. I’ll update this answer later when I’ve confirmed.

Just did a test. Can search for words in the PDF and also select and copy parts of the text.

Test if Close(Report) is SLOW on your System? – Mine 100x slower than C6

I did show this on the Wednesday Clarion Live Open Webinar 9/22/21 at 4:30. Test window looks like below. You can see on my system API delete is about 90x faster at 1000 pages. [image] Click “1. RTL Normal” to test time to Close(Report) which shows in the Normal column. Click “2. API Delete” and it will run code like this that deletes all preview files before Close.
