Changelog ========= Changes in libuca 2.1.0 ----------------------- Released on June 10th 2015 This is a combined bug fix and feature release. Most notably there is a new uca_camera_readout() API to grab arbitrary frames from cameras with in-camera memory, e.g. the pco.dimax. - pco: fix deadlock with streamed acquisition - pco: allocate memory also when just reading out - pco: do not reset storage mode - file: signal change of ROI and bitdepth and read complete filename path - ufo: update trigger policy - dexela: Correct the ROI dimensions respecting the binning mode - dexela: only allow symmetricall binnings - pylon and dexela: update to the new trigger API - Add FindClserSis to find the frame grabber SDK - sensor-width, sensor-height and sensor-bitdepth are not construct-only anymore Changes in libuca 2.0.0 ----------------------- Released on April 24th 2015 This release changes the trigger properties from a single "trigger-type" property to separate "trigger-source" and "trigger-type" properties. Apart from that numerous bug fixes and the following updates have been done since 1.6.2: - uca-benchmark measures more mode combinations. - A basic Python-based TANGO server has been added. - pco: Check for SiliconSoftware run-time version 5.2.2. - Add uca_camera_write to "write" arbitrary data to the camera. The semantics are camera-specific. - Added uca_plugin_manager_get_camerah to pass property values via a GHashTable. - The plugin directory can be queried via pkg-config. - The Python GIL is released on potentially long-running code paths. Changes in libuca 1.6.2 ----------------------- Released on November 14th 2014 This bugfix release solves a regression introduced with libuca 1.6.0 and documented at https://github.com/ufo-kit/libuca/issues/61. Changes in libuca 1.6.1 ----------------------- Released on October 29th 2014 This is a bugfix release smoothing out daily operation. In particular, we - release the Python GIL to avoid blocking on grabs - added missing property specification for exposure-auto in the pylon plugin - improved robustness of ROI setting in the pylon plugin - added global shutter support for pco.edge cameras Changes in libuca 1.6 --------------------- Released on September 19th 2014 This is mainly a cleanup and bugfix release with the following major updates: - Updated and fixed the Dexela plugin (v1.3.2). - Fixed a race condition for buffered acquisition. - Added `version` property to pco cameras. - Reset all property units and warn on override ### API changes - Removed "sensor-max-frame-rate" property. - Remove unused virtual `record_` functions. - Added `uca_camera_set_writable` and `uca_camera_is_writable_during_acquisition`. Changes in libuca 1.5 --------------------- Released on July 22nd 2014. ### API additions The base camera class has a new "buffered" property. If it is set to TRUE, a thread acquires data into an internal ring buffer. The readout API via uca_camera_grab has not changed. You can customize the number of pre-allocated buffers with the "num-buffers" property. A new uca_camera_is_recording call reflecting the "is-recording" property has been added. ### Minor changes - The GUI is more streamlined now and features region-of-interest selection and simpler zooming. - A new file "camera" can read a directory of TIFFs. This is an experimental implementation that only supports 8 or 16 bit TIFFs. - The xkit plugin does not depend on any third-party code any more but uses direct UDP communication. - The Dexela and Pylon plugins have been updated. Changes in libuca 1.4 --------------------- ### X-KIT detector plugin This release adds experimental support for X-KIT, a Medipix2 and timepix detector system developed at IPE/KIT. Note, that this requires a pre-built shared library and header files by the chip vendor. ### API changes - `uca_camera_grab` does not set an error when the stream finished in readout mode. Now, only `FALSE` is returned. ### Minor changes - A Travis instance was setup and Clang compilation has been turned on. - Performance of `uca-camera-control` has been increased and the GUI received color mapping of grey values. - Many fixes for pco.dimax, .edge and .4000. - Fix frame order in the GUI. Changes in libuca 1.3 --------------------- Released on July 24th 2013. ### Correct ABI versioning Until now, the ABI version was not set correctly and all versions prior 1.3 bear the same ABI version 1. This version has ABI version 2 and all subsequent versions will increase it if the ABI breaks. ### More control and sleeker design for the control GUI The look of the GUI was changed and includes now controls for acquisition as well as status information about the frames pixel values. Moreover, the frames can now also be scaled *up* to 200 and 400 per cent. Acquired frames can now also be stored as a raw binary dump. ### Minor changes - Added `sensor-pixel-width` and `sensor-pixel-height` to describe the cameras pixel size in meters. - Added `-c/--camera` flag to uca-camera-control to specify a camera name from the command-line and by-pass the choice window. - Added `-n/--num-frames` and `-r/--num-runs` to uca-camera-benchmark. - The mock camera produces Gaussian distributed, random data now. - Sane defaults have been set for binning and ROI and don't need to be repeated by cameras that don't support them. - Fix exposure time calculation for UFO camera. Changes in libuca 1.2 --------------------- Released on April 16th 2013. ### API break The interface of uca_camera_grab() has changed. The buffer must be provided as a void pointer (or gpointer in GLib speak), _not_ the address of a void pointer. Furthermore, uca_camera_grab() returns TRUE if grabbing an image was successful and FALSE if not. The plugin manager does not call the plugins "constructor" function directly but instantiates it via the GInitable initialization function. Therefore, all plugins must implement initialization code in the objects init function and flag errors in the init method from the GInitable interface. ### Restructuring of tools All binary sources are now found in bin/, with the GUI application now split off from the command line tools. Also, all tools are now installed with a common "uca-" prefix, e.g. `uca-camera-control` and `uca-grab`. ### Minor changes - Improved plugin packaging: Plugins can now specify a version number independent of libuca which is reflected when building RPM packages. - `uca-grab` is a lot more useful now and gained `--num-frames` and `--duration` parameters as well as the possibility to write frames as a single multi-page TIFF file. - Bug fixes for Dexela, pco and UFO cameras. Changes in libuca 1.1 --------------------- Released on October 26th 2012. ### Plugin System A new plugin manager is used to instantiate camera objects from a shared library. Instead of calling `uca_camera_new`, a plugin manager is created that looks in pre- and user-defined directories for DSOs that match `libuca[A-Za-z].so` and used to instantiate: UcaPluginManager *manager; UcaCamera *camera; manager = uca_plugin_manager_new (); camera = uca_plugin_manager_get_camera (manager, "foo", &error); The plugin manager adds a dependency on GModule (pkg-config package `gmodule-2.0`) that is part of GLib. ### Minor changes - It is now possible to generate GObject introspection meta data to bind libuca to all languages that support GObject introspection. A first experiment of UcaDevice using this was successful and the camera showed up in Jive. - Added virtual function uca_camera_stop_readout() to cleanup after using uca_camera_start_readout(). - There is now a mechanism to register and query physical units of camera properties. Camera plugins must call uca_camera_register_unit() for each property that they want to have a physical unit (e.g. UCA_UNIT_SECOND) attached to. Client programs can get this information with uca_camera_get_unit(). - The control GUI learned some new tricks: live histogram, zooming and recording into an internal ring buffer. Changes in libuca 1.0 aka 0.6 ----------------------------- Released on September 19th 2012. ### GObject Type System Instead of using a home-grown type and class system, we switched to the GObject system as part of GLib. This effort has the advantage of much more typesafe properties and better signal and closure handling. Most of the ideas and approaches of libuca 0.5 have been transfered. However, instead of trying to initialize each camera first and having the user decide what to use, the user must now determine the used camera at compile time or use the factory pattern to delegate this to run-time. ### Tango Wrapper The old Tango wrapper has been superseded by a generic one that proxies GObject's to the Tango bus. This makes things a lot easier, for example reacting on remote property setting and more robust type safety. The wrapper is developed as an external project at ISS by Volker Kaiser. Changes in libuca 0.5.0 ----------------------- - Put work under LGPL 2.1 - Adapt cameras/ipe.c to support the current driver API - Adapt cameras/pco.c to support libpco 0.3 - API changes - new enum type uca_buffer_status - uca_cam_grab_callback()s have to return uca_buffer_status - typedef all types - New symbols: - uca_cam_release_buffer()
