svglite (development version) Unreleased

  • svglite now uses systemfonts for text metric calculations and font family lookup.

  • svglite now directly encodes raster data into png instead of rendering it through cairo. If the provided raster is smaller than the final requested size it will be resized.

  • SVG’s can now get a top-level id so that style definitions doesn’t spill into the surrounding HTML (#91)

  • Dimensions are now encoded into the top-level <svg> tag (#90)

  • Starting a new page creates a new file if the filename supports it (#98, @vandenman).

  • The inline devices now defaults to the same dimensions as svglite() (#89)

  • Clip defs are now only written if they don’t already exist (#110)

  • Clipping is now defined with outer groups instead of on each element (#109)

  • svglite now uses cpp11 instead of Rcpp (#100)

  • svgz output is now supported natively (#6)

  • Text adjustments are now encoded in css where possible (#107)

  • The use of textLength CSS property can now be turned of (#118)

  • web font imports can now be given when creating an svg (#108)

  • Add scaling argument to devices to control line-width and text scaling (#115)

svglite 1.2.3 2020-02-07

  • The radius of circles is no longer expressed in pt (#93, @vandenman).

  • Dimensions smaller than 1 now retain two significant figures (#94, @ilia-kats).

  • @thomasp85 takes over as maintainer

svglite 1.2.2 2019-05-17

  • Improvements to reproducibility of generated SVGs: Negative zeros are now treated as positive, and the clip ID are now generated from truncated elements.

  • svglite now uses the polygon SVG element. This ensures that polygons are properly closed (#82).

  • Text metrics are now correctly computed for Unicode characters in plotmath expressions (#81).

svglite 1.2.1 2017-09-11

This release makes svglite compatible with gdtools 0.1.6

svglite 1.2.0 2016-11-04

New features

  • The device functions gain system_fonts and user_fonts arguments.

  • Two new vignettes: vignette("fonts") and vignette("scaling"). The vignette on fonts explains in detail how to use the new fonts arguments and why. The vignette on scaling goes over scaling issues, e.g. when embedding svglite outputs in a web page.

  • xmlSVG() gains height and width arguments (#66).

  • New stringSVG() device function for quick testing.

Improvements

  • Greatly improves the performance of svgstring() (#58).

  • Clip paths now get a unique identifier to avoid collisions when multiple plots are included in a document (#67).

  • Raster graphics are now correctly cropped (#64) and handle transparency properly.

  • The dimensions of text fields are now hardcoded in the SVGs to prevent alignment issues.

Bug fixes

  • editSVG() works again (#56).

  • The dashes in lines with lwd < 1 are scaled better (#68).

  • Transparent blacks are written correctly (#62, #63).

  • Text is now scaled correctly (#72, #59). See also the new vignette on scaling.

svglite 1.1.0 2016-02-09

  • Text metrics now converted from points to pixels (#45, #48) - this fixes text alignment issues.

  • Intermediate outputs are always valid SVG (#53).

  • New svgstring() returns plot as a string (#40, @yixuan).

  • Use raster test compatible with older versions of R.

  • Add support for clip(). This also fixes a number of minor issues with grid graphics (@yixuan, #47 and #49).

  • Fix incorrect device size (#50).

svglite 1.0.0 2015-12-09

svglite is fully featured svg graphics device that works on all platforms, forked from RSvgDevice. It supports all graphics device features:

  • All types of line dashing are supported (#15). All line end and line join styles are supported (#24).

  • Text is now coloured, and uses the same default fonts as R (Arial, Times New Roman, and Courier). Font metrics are computed using the gdtools package so that plotmath() and strwidth() now work.

  • Transparent colours are now generated with rgba() rather than using stroke-opacity and fill-opacity styles (#16). NA fills and colours are translated to “none”.

  • par(bg) affects the background colour (#8).

  • Rasters are supported by embedding base64-encoded pngs in a data url (#2).

  • polypath() is now supported, which also allows the showtext package to render fonts correctly with this device (#36).

We also made a few other tweaks to the rendered SVG:

  • Only the viewBox attribute of <svg> is set (not width and height): I’m reasonably certain this makes it easier to use in more places (#12).

  • Default styling properties are specified in a global <style> element: this reduces overall file size, and should make it easier to re-style the output for your own needs.

  • You can now only produce a single page per device - previously this worked but produced incorrect output (#5).

  • Output no longer contains dummy <desc> element (#4)

And added some helper functions:

  • xmlSVG() and htmlSVG() make it easier to view generated SVG, either as raw XML or in RStudio/the browser.

  • editSVG() opens the SVG in the default SVG viewer/editor.
