ragg (development version)

  • Make sure the linejoin/linemitre setting is honored when drawing rectangles (#162)

ragg 1.3.0

  • Added supported for new graphics enigine features: Groups, paths, luminance masks, and glyphs
  • Add a switch (defaults to on) to snapping rectangles to the pixel grid when they are only drawn with fill (no stroke)
  • Fixed a bug causing repeated warnings when using a font at 0 size (#130)
  • Silence a bug in clang-ASAN that incorrectly reported sanitiser issues

ragg 1.2.7

  • Fix a stack imbalance bug

ragg 1.2.6

  • Fix symbol rendering bug on windows (#132)
  • Add support for dev.capabilities() (#105)
  • Prepare for Arm Windows

ragg 1.2.5

  • Fix a bug when rendering glyphs from a colour font that also provide greyscale glyphs (#105)
  • Move sprintf() to snprintf() in the AGG source code to comply with Arm64 deprecation
  • Better guard against bad input (#116)

ragg 1.2.4

  • Fixed a regression that turned off line mitre support (#119)

ragg 1.2.3

  • Second attempt at rendering jpegs with transparent background. Now, the buffer is filled with solid white before any drawing happens.
  • Fixed a bug that resulted in newlines being rendered as missing glyphs on some Linux versions (#111)

ragg 1.2.2

  • MacOS: configure script now uses the local system dependencies provided by CRAN via pkg-config. Autobrew libs are used as fallback on non-cran servers only.

ragg 1.2.1

  • Fix bug that caused R to crash when writing tiff files with transparent background (#97)

ragg 1.2.0

  • Add support for new graphic engine features:
    • Arbitrary clipping paths
    • Alpha masks
    • Linear and radial gradients
    • Tiling patterns
  • Use white as background when passing in a fully transparent background colour to devices that doesn't support alpha (notably jpeg) (#91)
  • ragg now defers symbol font resolving to systemfonts which makes it possible to register alternative symbol fonts using register_font() (#90)
  • Filenames in UTF-8 are now treated correctly on Windows (#87)
  • Fix size selection of non-scalable fonts when the requested size is bigger than the available

ragg 1.1.3

  • Use int32_t instead of int32 in old code
  • Prepare for UCRT
  • Better error message when failing to allocate memory for the buffer (#82)
  • Increase storage size limits for paths (#80)

ragg 1.1.2

  • Fix bug in agg_capture() that resulted in premultiplied colour values being returned

ragg 1.1.1

  • Fix a bug in glyph dimension lookup that could cause system crashes
  • Fix bug in font caching when multiple ragg devices are used simultaneously

ragg 1.1.0

  • Major version release to signify the much improved text support that includes full support for right-to-left scripts and bidirectional text (mix of RtL and LtR scripts). It further adds full support for OpenType features and non-scalable fonts.
  • Re-exporting register_font(), register_variant(), and font_feature() from systemfonts
  • Re-exporting get_font_features() from textshaping
  • Use new textshaping API and handle font fallback correctly
  • Add support for rendering colour fonts (#1)

ragg 0.4.1

  • Skip text tests on CRAN as no text is plottet on the CRAN solaris machine
  • Fixed a bug resulting in system crash on certain systems, as well as clang-ASAN error. (#59)

ragg 0.4.0

  • ragg now requires the Harfbuzz and Fribidi libraries to be available when installing from source due to their dependency in the textshaping package.
  • Move text shaping to the new textshaping package.
  • Fix agg_capture() on big endian systems (#49, @QuLogic)
  • Fix use of symbol font on Windows by moving to Segoe UI Symbol which has a Unicode charmap (#51)
  • Better compatibility with knitr and ggplot2::ggsave()

ragg 0.3.1

  • Roll back support for new clipping options in the graphic engine as it was buggy.

ragg 0.3.0

  • Fix a bug when plotting partially transparent raster (#44)
  • Add a scaling argument to all devices allowing you to change relative scaling of output.
  • Horizontal and vertical text are now snapped to the pixel grid in order to improve rendering quality.
  • Internal changes to prepare for coming updates to the graphic engine

ragg 0.2.0

  • Fix compilation on R <= 3.3 by including Rdynload.h explicitly
  • Fix a performance regression when plotting text (#33)
  • Fix erroneous width calculations of strings starting with a space on windows (#32)
  • Fix a bug in agg_capture() where the output became mangled if device height != width
  • Fix a bug in raster support where raster data did not get premultiplied before rendering (#38, @yixuan)
  • Fix an integer overflow issue in the AGG source code

ragg 0.1.5

  • Fix compilation on macOS

ragg 0.1.4

  • Fix a bug in AGG's font manager that ignored the font index when it stored and retrieved cached faces

ragg 0.1.3

  • Fix bug preventing ragg from displaying 50% transparent black
  • Another attempt at fixing compilation on mac build machines

ragg 0.1.2

  • Fix compilation on certain Linux systems by preferring dynamic libraries over static ones (#25, @jimhester).

ragg 0.1.1

  • Avoid a bug when the call to start a device included too many characters (#16)
  • Fix integer overflow runtime errors in agg source code (agg_scanline_storage_aa.h), by changing storage to long
  • Remove benchmarking vignettes as it was causing too much trouble on stripped down systems... They are still available on https://ragg.r-lib.org
  • Better build setup to properly build on all macOS systems

ragg 0.1.0
