LibreOffice Writer displays embedded SVG files that use the 'crispEdges' value for the shape-rendering property with blurry edges and corners. The rendering result is the same if the said value has not been set. Also, rendered PDF files created from these Writer documents result in similarly blurry images.
This is particularly detrimental for documents that contain QR codes or other barcodes embedded as SVG images, since sharp precision with these kinds of images is essential, and anti-aliasing is harmful.
Steps to Reproduce:
1. Embed an SVG image that uses the 'crispEdges' value for the shape-rendering property.
(2. Optional: export as PDF.)
1. The embedded SVG has blurry edges.
(2. Optional: the image in the PDF has blurry edges.)
1. The edges and corners should be sharp.
(2. Optional: the edges and corners in the generated PDF should be sharp.)
