In ragg: Graphic Devices Based on AGG

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

• Basic setup of package. png, tiff, ppm, and buffer capture support
• Added a NEWS.md file to track changes to the package.
