Title: Printing Picture on PDF Report very SLOW a- any way to speed up the printing?
Post by: rjolda on October 09, 2025, 07:07:59 AM

Hi,
Clarion C11
NT 14.36
I have a report which prints to PDF using Net Talk Extension to report procedure with SV PDF Generator.
When I do not include a picture on the report it is blazing fast.
When I DO include a picture on the report it bogs down and takes about 4 seconds.... but it does print correctly.
Picture is 3.4 Mb ( from phone camera).  It is full color - however, I don't need to print color as most places will probably print b/w.

So any way to speed up the printing with the photo?
Should I use a different PDF generator??

I did some digging and PDF can be printed as an image and a few other things.  However, I don't see any settings for PDF print.

Any insight or suggestions appreciated. 
Thanks,
Ron

Hi,
Charles of Lansrad suggested that I use the Bitmap Class of ImageEx and compress it down - indeed, I can compress it from 3.4M to 300K with little loss in quality for my purposes.  Prints faster!

SLow JPG image printing - solved.
I got some insights from folks on discord.
While I used imageEx to shrink original JPG file from 4 MB to 200KB it still printed very slowly.
The answer was to actually change the size of the picture.  It was 4080px x 3072 px.  I shrunk it down to 408 x 300 and it was the RIGHT size and printed Normally!  So the answer for me was taking the original picture and shrinking it to 10% and compressing it with JPG compression to 20 %.  Just right!
