Minor glyphs positioning issue

For some PDFs library produces slightly incorrect positioning of particular glyphs:

SVG1:

PDF2:

SVG2:

pdf1.pdf
pdf2.pdf

Thanks for reporting this issue.

Regarding the unaligned letters, I get the same result in Adobe Reader (first image) and Firefox (second image) at some resolutions. This is likely rounding errors due to transformations applied on individual letters in the headers.

Regarding the space before the ending "n", I can't reproduce this in PdfToSvg.

Questions:

• Are you using the latest version of PdfToSvg?
• Which SVG viewer do you use?
• Are you using any non-default options in the calls to ToSvgString or SaveAsSvg?
• Is there some post processing on the SVG?

This seems to be caused by a font creation date that was outside the expected range. This will be fixed in version 1.6.0.

Are you using the latest version of PdfToSvg?
Yes, the latest sources from master branch

Which SVG viewer do you use?
Edge or Chrome browser and WPS Office pdf viewer/editor - both produces same render (at least I don't remember any difference)

Are you using any non-default options in the calls to ToSvgString or SaveAsSvg?
Yes, my bad, sorry. I completely forgot, I added some options in my software half year ago:) Reported result was produced with

            var svgConversionOptions = new SvgConversionOptions()
            {
                CollapseSpaceEmbeddedFont = 0.2,
                FontResolver = FontResolver.EmbedWoff,
            };

Default options gives correct result.

Is there some post processing on the SVG?
No.

Thanks for the followup. The problem in PDF2 should now be fixed in version 1.6.0.
