300 (600) dpi resolution for all PDF Images

Dima · July 2018

I need to generate a PDF with a couple of images
with 300 (600)dpi (if Scale needed) resolution. Currently I'm getting
96dpi (screen resolution), where or how can I change it?

I know about ScaleImage and CompressionLevel.
But some images (when ScaleImage = False) have 6000 resolutions in result PDF.

Can you add ScaleImageResolution property to PDF Settings?

Hi Dima,

ReportBuilder will not scale any images in PDF unless the ScaleImages property is set to True. ScaleImages performs a StretchDraw on the image, essentially scaling the image and its data to the control size. Otherwise, the original image data is included in the PDF file and the PDF reader will scale the image to the size allotted.

I will add it to our list of possible enhancements to allow more control of the ScaleImages property for a future release. Currently you will need to manually scale your images, perhaps using image software.

Hi Nico,

>>ReportBuilder will not scale any images in PDF unless the ScaleImages property is set to Tru
Sorry. Of course I was wrong.
I meant the 300 (600) dpi resolution for all Scaled PDF Images (when ScaleImages = True).

>>Currently you will need to manually scale your images.
I do this now for all static images.
But I have problem with user reports and user images.
Example: Price list that show image 1x1 inch
Some user images in DB has resolution 4000x3000 and more.
If ScaleImages = False then pdf file will be very large.
If ScaleImages = True - image quality is not very good.

I recommended my users to used "Microsoft Print to PDF" printer (in this case look like images scaled up to 600 dpi) fo export this report in pdf. But this not work for emails. My customers want to send this report by email...

Hi Nico,
What about more control of the ScaleImages property?

Hi Dima,

This feature did not make it into the latest release but it is still on our list of possible enhancements for a future release.

Thanks for your feedback.
