Rendering 1 / 2-bit graphics / Aliasing

[Tobias]

It would be nice to be able to render images for electronic shelf labels with Reports.NET. For these ePaper-Displays the graphics usually are b/w or b/w/r/y. Is there a way to render such graphics WITHOUT anti-aliasing?

Hello,

Please try to set the Smoothing=false property for the Image component.

Thank you.

Thanks, but you got me wrong. My question was not about rendering an image within an StiReport, but to render it AS an image WITHOUT antialiasing.

If I render render a StiReport as e.g. a PNG, the text, borders etc are all antialiased - this does not work very well with 2 or 4 color ePaper displays. So my question is, if the antialising can be disabled when exporting a StiReport as PNG.

What I haven't tried yet is to export as an SVG and then use SkiaSharp to render the image (which allows to disable antialisaing). But I guess this would require some post processing of the SVG to disable fill/stroke overrides that might override the alisaing controlled by Skia.

Hello,

Please try to use the following option:
StiOptions.Engine.DisableAntialiasingInPainters = true;

Thank you.
