v1.4.4

Changes in v1.4.4

• bug fix with missing dynamic libraries in v1.4.3 and v1.4.2 (#61; thanks to Ole Streicher)
• bug fix with test suite using make -j (#62; thanks to Ole Streicher)

v1.4.3

Changes in v1.4.3

• bug fix with parsing longer escape sequences that contain shorter ones, like \beta (containing \b) and \gamma (containing \ga)
• added \odot symbol
• revert marker 1 to point plotting, not resized with character height

v1.4.2

Changes in v1.4.2

• bug fix with build on Mac OS: explicitly request static libs for libgiza.a and libpglot.a
• bug fix with pkg-config failing to find cairo.h
• bug fix with weird black screen on Mac OS after clicking in a plot window (#55)
• issues in test suite fixed (#50)
• bug fix with giza_circle (#52)
• added automated build and test suite to github actions workflow

v1.4.1

Changes in v1.4.1

• quieter output from mp4 device
• bug fix in release workflow

v1.4.0

Changes in v1.4.0

• added mp4 driver, can simply give "file.mp4" as the device to generate mp4 file
• can amend flags to ffmpeg using GIZA_FFMPEG_FLAGS environment variable
• automated cleanup of temporary .png files used to make the movie
• add registered and copyright sign as symbols (thanks To Hiroyuki Ito)
• Add support for '1' and '2' options to giza_box (thanks to Hiroyuki Ito)
• Add support for PG[SQ]ITF. PGPLOT has three image transfer functions defined for PGIMAG: linear, log, sqrt. These are now implemented (thanks to Harro Verkouter)
• Fix giza_set_colour_table to set colour indices. The function would warn about inconsistent entries in the controlPoints and return with an error, not setting the colour-index table (thanks to Harro Verkouter)
• Follow PGPLOT auto-linestyle in PGCONT (thanks to Harro Verkouter)
• Address char height/line width scaling issues: According to PGPLOT documentation, symbols are drawn using current attributes character height and line width (thanks to Harro Verkouter)
• license moved to LGPL rather than GPL

v1.3.2

Changes in v1.3.2

• bug fix with spaces at end of string causing failure on open_device in Fortran interface (#35)

v1.3.1

Changes in v1.3.1

• giza_axis and giza_tick added to libcpgplot interface (#12)
• fixed various documentation issues
• API documentation automatically updates via github workflow

v1.3.0

Changes in v1.3.0 compared to v1.2.1

• new library functions giza_set_motion_callback and giza_end_motion_callback
• can now specify a callback function func(x,y,mode) that will be called every time the cursor moves
• implemented giza_axis and giza_tick with replacement functionality for PGAXIS and PGTICK (#12)
• Fortran API no longer trims text strings before passing them to giza routines. This enables one to send a string of blank characters with an opaque background colour in order to erase previously drawn text

v1.2.1

Changes in v1.2.1 compared to v1.2.0

• bug fix specifying device at prompt with directory path, e.g. dir/file.png

v1.2.0

Changes in v1.2.0 compared to v1.1.0

Features:

• new giza_set_number_format() sets format to use by giza_box() (thanks to chafar)
• giza_open() now detects and handles errors occurring during setup of the new device
• PGEND()/cpgend() now closes all open devices, as per documentation (thanks to H. Verkouter)
• giza build includes freetype and fontconfig libraries
• improved font memory management (thanks to H. Verkouter)

Bug fixes:

• build failure caused by giza_box_time fixed (#21)
• bug fix with internal logic in naming png files if blank page exists (thanks to Aard Keimpema, #28)
• seg fault fixed when multiple devices are opened and closed in random order (thanks to H. Verkouter)
• fixed possible buffer overflow in giza_format_number (thanks to H. Verkouter)
• avoid the 'initial declarations are only allowed in C99 mode' error (thanks to M. Hutchison)

Other:

• deleted unused _giza_change_size() function
• updated documentation for github
• automated build checking, api documentation and release-on-tag via github actions
