ActivVisionTools in general

o Functionality:
  • The property BackColor of all tools is used now only for sub-components where the newly defined color is useful.
  • Each ActivVisionTool has a new property called 'UseIconMode'. If this property is set to true the control is displayed as an icon in design mode and will not be visible in user mode.
  • All tools can now be edited in design mode.
  • If the ActivVisionTools start a particularly time-consuming operation, e.g, the training of an alignment anchor, this is now signaled by a busy cursor.

o Bug Fixes:
  • If you open an ActivvisionTools project from within Visual Basic, the description file (DSC-File) containing the settings is now loaded correctly.

o Manual:
  • The manual Getting Starting Started with ActivVisionTools is now available in its 4th edition. It has been extended slightly and updated to reflect the changes in ActivVisionTools 2.0.
  • The example Visual Basic projects have been adapted to version 2.0.

ActivView

o Speed-Up and Enhancements:
  • The new sub-tool AVTViewFGParameter allows to configure each supported frame grabber in detail.
  • The new sub-tool AVTViewExecuteSimple provides a button to start and stop your application.

o Miscellaneous:
  • The support tool AVTViewImageGrabber has been renamed to AVTViewFG.
  • The example images in AVTViewFG's combo box 'Files' are now sorted alphabetically.
  • The storing of paths where images are searched for has been improved; the example image sequences have been adapted accordingly.

o Functionality:
  • The history of combo box containing the files in AVTViewFG is now saved automatically.
  • An ROI is now activated based on the distance of the 'clickpoint' to the ROI border and/or pickpoints.
  • AVTViewStatus now provides a property page by which its appearance can be configured easily.

o Bug Fixes:
  • ROIs of type circular arc no longer display extra (ghost) handles.
  • The font used to display text in AVTView is now stored correctly.
  • Because AVTViewCalibration calculates the extent of a pixel, i.e., its height and width, and not its size, i.e., its area like ActivGeoCalib, the text of the corresponding label has been changed. Note, that AVTViewCalibration assumes pixels to be quadratic, therefore the height of a pixel is identical to its width.
  • The orientation of elliptic ROIs is now stored correctly.
  • The 'Pixel Height' displayed in AVTViewCalibration was wrong for other units than pixel. This problem has been fixed.

o Manual:
  • The User's Manual for ActivView is now available in its 4th edition. It now shows how to use ActivHistogram and ActivLineProfile to inspect image quality. Furthermore, it explains how to configure frame grabbers using the new sub-tool AVTViewFGParameter and how to modify the list of frame grabbers which can be selected. Besides, the manual has been updated to reflect other changes in ActivVisionTools 2.0.
  • A new example project has been added showing how to inspect image quality. Besides, all example Visual Basic projects have been adapted to version 2.0.

ActivZoom

o Functionality:
  • ActivZoom now displays the coordinate values using the currently selected unit.

ActivGeoCalib

o Functionality:
  • Nine new parameters have been made accessible as properties. Further eight parameters, formerly only accessible via the GUI, are now also properties.

o Manual:
  • The User's Manual for ActivGeoCalib is now available in its 3rd edition. It has been extended slightly and updated to reflect the changes in ActivVisionTools 2.0.
  • The example Visual Basic projects have been adapted to version 2.0.

ActivAlignment

o Functionality:
  • The results of AVTAlignment, e.g., its status, are now returned as tool results instead of ROI results.
  • ActivAlignment now supports ROIs based on polygons.

o Bug Fixes:
  • Trying to edit an ROI of AVTAlignment in fixed mode no longer causes a runtime error.

o Manual:
  • The User's Manual for ActivAlignment is now available in its 2nd edition. It now contains a section showing shows how to access the alignment results directly via the programming interface. Furthermore, the manual has been extended and updated to reflect the changes in ActivVisionTools 2.0, especially the improved handling of ActivDecision.
  • A new example project accesses the alignment status via the programming interface. Besides, all example Visual Basic projects have been adapted to version 2.0.

ActivMeasure

o Bug Fixes:
  • The distance between edges in AVTMeasure with circular shape ROIs is now calculated correctly.

o Manual:
  • The User's Manual for ActivMeasure is now available in its 3rd edition. It has been extended and updated to reflect the changes in ActivVisionTools 2.0, especially the improved handling of ActivDecision.
  • The example Visual Basic projects have been adapted to version 2.0.

ActivBarcode

o Functionality:
  • ActivBarcode now supports ROIs based on polygons.

o Manual:
  • The User's Manual for ActivBarcode is now available in its 3rd edition. It has been extended and updated to reflect the changes in ActivVisionTools 2.0, especially the improved handling of ActivDecision.
  • The example Visual Basic projects have been adapted to version 2.0.

ActivBlobFinder

o Functionality:
  • ActivBlobFinder has a new mode for segmentation. This mode is based on two thresholds (lower and upper). Besides this, it is possible to specify whether the gray values inside or outside this range are to be selected.
  • ActivBlobFinder now supports ROIs based on polygons.

o Manual:
  • The User's Manual for ActivBlobFinder is now available in its 4th edition. It has been extended and updated to reflect the changes in ActivVisionTools 2.0, especially the improved handling of ActivDecision. The section describing how to access the results of ActivFeatureCalc via the programming interface has been removed, as this is described in the new User's Manual for ActivFeatureCalc.
  • The two examples showing how to use the programming interface have been removed. All example Visual Basic projects have been adapted to version 2.0.

ActivFeatureCalc

o Functionality:
  • The new support tool AVTFeatureCalcGray allows to calculate gray value features.

o Bug Fixes:
  • The feature Outer Circle was not calculated correctly. This problem has been fixed.
  • The features 'Area', 'Radius Major', 'Radius Minor', 'Contour Length', 'Radius Inner Circle', and 'Radius Outer Circle' were calculated wrongly if used with the 2D calibration (AVTViewCalibration). This problem has been fixed.

o Manual:
  • The functionality of ActivFeatureCalc is now described in detail in the new User's Manual for ActivFeatureCalc.

ActivDataView

o Functionality:
  • The sliders are no longer reset by an update.

o Bug Fixes:
  • ActivDataView now works correctly with multiple empty ROIs.

ActivDecision

o Speed-Up and Enhancements:
  • The functionality of ActivDecision has been partitioned into three sub-tools: AVTDecision now only shows the overall evaluation of the application and allows to open the other two sub-tools via its context menu. AVTDecisionViewResults displays the results of all connected ActivVisionTools; furthermore, it allows to formulate individual conditions and displays the evaluations of tools, ROIs, objects, and features. AVTDecisionViewDefaults allows to specify default conditions on tool and ROI level. Note, that AVTDecision has a new icon.

o Functionality:
  • The sliders are no longer reset by an update.
  • If you select objects in the tree of AVTDecisionViewResults, they are now highlighted in AVTView.

o Manual:
  • The functionality of ActivDecision is now described in detail in the new User's Manual for ActivDecision.

ActivFile

o Functionality:
  • The control AVTOutputDataSelect, which allows to select data to be written to the log file, was revised to extend and facilitate the possible selections.

ActivSerial

o Functionality:
  • The control AVTOutputDataSelect, which allows to select data to be sent to the serial interface, was revised to extend and facilitate the possible selections.
