[HTML-3199] - Improvements to space detection algorithm
It is common for PDF files to simulate spaces in text by simply moving the cursor where a space should be. It is up to the PDF reader to interpret where spaces may be added when extracting the text. This behavior is not defined within the PDF specification and we have found when testing files in other PDF Viewers that the results can vary massively.
We have introduced AI concepts to the detection of spaces in FormVu which has produced improvements, particularly in text with tight kerning where the width of a space is smaller than usual. This has also improved files where spaces were unnecessarily added in text that has wide spacing.
[HTML-3196] - Vendor Prefixes in CSS
Updated CSS transform vendor prefixes to add the unprefixed variant and to remove -o and -moz variants. We continue to support IE9 onwards and modern versions of Chrome, Firefox, Edge & Safari.
