Revision

Notes

10.5
  • FEATURE_EXPOSURE now accommodates 1 or 3 parameters (if supported by the camera model). The additional 2 parameters allow the user to specify exposure limits to be applied for AUTO operations.
  • AUTO and ONEPUSH operations can now be performed for FEATURE_GAIN (if supported by the camera model).
  • FEATURE_AUTO_ROI can now be used to limit the set of pixels used for AUTO operations (if supported by the camera). Currently, the features that can use the AUTO_ROI, are FEATURE_EXPOSURE, FEATURE_GAIN, and FEATURE_WHITE_BAL.

10.4
  • Added support for the Navitar (Generation 2) Zoom and Fine Focus Controller. More specifically, added the following new functions:
    • PxLGetNumberControllers will enumerate all controllers connected to the system, providing identifying information on each.
    • PxLAssignController will assign a specific controller, to a camera. Features implemented by this controller, are then controlled via the camera identifier.
    • PxLUnassignController will un-assign a specified controller, from a camera. That controller can then be assigned to a different camera.

10.3
  • Added support for 10-bit packed format (for cameras that support this format).


10.2 
  •  PxLGetEncodedClip will allow an application to capture a video clip from a stream of camera images, encoding them using a specified encoding technique.
    Currently, only H.264 encoding is supported.

  • PxLFormatClipEx converts a captured video stream (encoded or not), into a video file suitable for viewing via a video player.
    Currently, .avi and .mp4 video formats are supported.


10.1 
  •  Added support for General Purpose Input (GPI) for PL-D cameras.

  • Added CAMERA_INITIALIZE_EX_FLAG_ISSUE_STREAM_STOP flag for PxLInitializeEx. 

  • Increased USB 3.0 interoperability for Power Saving options.

  • Reduced minimum exposure time for PL-D721, PL-D722 and PL-D725 cameras..

  • Bug Fixes.

 
10.0
  • Compliant with the latest USB3 VISION standard for all PL-D cameras.
IMPORTANT NOTE: U3V Compliant cameras will not work with Release 9.3 host software (and older).

  • FEATURE_FOCUS can now accept upto 2 parameters when PxLSetFeature is called with the FEATURE_FLAG_ONEPUSH bit of the flags register is set (to perform a one-time auto focus operation). These two additional parameters (if supplied) will represent the range over which the auto focus is to be applied.

  • Added support for dotNet v4.5 platform.

  • Removed support for Windows XP.

  • Various bug fixes.
9.3
  • Added the new feature FEATURE_SPECIAL_CAMERA_MODE. This feature is currently only supported on the new PL-D752 cameras. It allows you to put the camera in a special mode of operation that accommodates a wider range of frame rates.

  • Added support of the feature FEATURE_AUTO_ROI to the PL-D camera line. This new feature, when used with FEATURE_WIDE_SHADING to allow the user to white balance the camera using a specified portion of the image.

  • Add a new function:
    • PxLGetCurrentTimestamp to allow an application to sample the image timestamp clock of a camera (without actually capturing an image).            
    • PxLSetPreviewStateEx behaves identically to PxLSetPreviewState - but has an additional callback function to accommodate changes made to the preview window (required for Linux implementation). 


  • Added support for the pixel format PIXEL_FORMAT_XXXX_PACKED_MSFIRST. This new 12-bit packed pixel format may be used with certain models of PL-D cameras.

A bug which caused byte swapping in the PxLCameraRead & PxLCameraWrite functions has been fixed.
Jan 2005
Improvements to PxLFormatClip to improve performance and limit dropped frames.
Dec 2004
Fix for using multiple descriptors. These were not working properly if tabs were switched in the Dev App.

There is a new PixeLINKApi.bas file included in the install for use with Visual Basic.

From version 4.0, the following changes have been made:

  • New functions have been added:
    • PxLCameraRead & PxLCameraWrite - read and write blocks of data from the advanced address space of the camera registers. The format of the data is camera dependant and is defined in the relevant camera system guide.

  • Flip and Rotate modes have been added to accommodate vertical and horizontal image flips as well as image rotations. If these are not supported directly by the camera, they will be performed by the driver on the host.

  • A feature to control white shading was added to allow control of individual color gains.

  • A number of new Pixel_Formats have been added for compatibility with color Bayer patterned cameras. The formats also take into account the rotation and flip modes of the camera/driver.

  • In the documentation, the term "decimation" has been replaced with "pixel addressing mode". Several pixel addressing modes have been added for cameras that support decimation, binning, averaging and resampling.

  • The API supports features compatible with IIDC specification 1.31.

  • Multiple Descriptor structures are possible depending on the firmware of the camera being used. The latest descriptor format now includes the pixel addressing mode, white shading and rotate status of the camera. The new data is appended to the end of the descriptor structure. Special instructions to ensure backwards compatibility can be found in Appendix D.
