I have to port rdlc reports from .NET to CORE. Since rdlc are not supported yet, I tried to recreate them using Migradoc.

The original one:
Attachment:
dots_or.PNG
dots_or.PNG [ 3.83 KiB | Viewed 222 times ]


My current result is the following:
Attachment:
dots_new.PNG
dots_new.PNG [ 6.91 KiB | Viewed 222 times ]


I created png dots, converted them to base64 strings and added them using the following code:
Code:
cell.AddImage(base64StringVariable)


Since the size of each image is very low, just 12x12 pixels, the pdf has a quite poor quality.
Do you have some hint in order to improve quality?

The obvious hint: use larger images.

To prevent Adobe Reader from anti-aliasing the images, set "image.Interpolate = false;" for the image or disable image anti-aliasing in Adobe Reader.

Thanks.
...I apologize. Didn't see the properties Height and Width of the returned Image object.
However, I can't find "image.interpolate"
