  • scaler C++ extension: added alternative implementations of C99 features so that this extension is now compatible with Microsoft Visual C++ compiler (was only compatible with gcc)
  • Replaced all Fortran 77/90 extensions by Cython extensions:
    • Building guiqwt no longer requires a Fortran compiler (but only a C/C++ compiler for the C++ scaler extension and the C Cython extensions)
    • 2-D histogram items are drawn 3 times faster than before
    • The Mandelbrot example runs faster too

Bug fixes:

  • guiqwt.image_nanmin/_nanmax: bug fixed when data is a numpy.ma.MaskedArray object

  • (Issue 37) Plot axis widget: added support for mouse double-click to set the axis range

Possible API compatibility issues:

  • guiqwt now requires Python 2.6 (Python 2.5 support has been dropped)
  • guiqwt.io module: file type filters are now sorted depending on data types

  • FreeFormTool/MultiLineTool: fixed warning when clicking the first two points if these two points are at the exact same position (happened only when creating such a shape on an empty canvas)
  • Fixed "Edit data..." tool: oedit function returns None when dialog is canceled or an array when it's validated (fixed "truth value" error)
  • (Issue 32) pyplot/better compatibility with Matplotlib: plot now accepts lists instead of NumPy arrays
  • (Issue 33) tools.LoadItemsTool: parent constructor was not called
  • (Issue 36) plot.PlotManager: fixed typo when setting the plot manager to plot_id

Version 2.2.0

New features:

  • Fixed minimum value for histogram display
  • Fixed Issue 16: use double precision for point baseclass
  • Fixed rounding error in image.assemble_imageitems: concerns the snapshot tool, and the new rotate/crop dialog box (Rotate/Crop dialog: added a specific test checking if exported image is exactly identical to the original image when the cropping rectangle has the same size and position as the image below -- see rotatecrop.py test script).
  • scaler: linear interpolation was inactive on image edges (first/last col/row)
  • ImagePlot widget: fixed aspect ratio when showing the widget for the first time
  • Events/Hit test:
    • Plot item: fixed AttributeError with cursors (when clicking on the canvas with no current active item)

    • QuadGridItem: allow set_data to update X,Y along with Z
    • new item PolygonMapItem: PolygonMapItem is intended to display maps i.e. items containing several hundreds of independent polygons
  • guiqwt.builder.make.error: added options 'errorbarwidth', 'errorbarcap', 'errorbarmode' and 'errorbaralpha' (avoid having to tweak the ErrorBarParam to customize these settings)
  • guiqwt.pyplot/pydicom: avoid the annoying warning message about the DICOM dictionnary revert
  • guiqwt.tools:
    • EditItemDataTool: new tool for editing displayed curve/image data using a GUI-based array editor (this feature requires the spyderlib library)

Bug fixes:

  • ErrorBarCurveItem (error bar curves):
    • now handling NaNs uncertainties properly
    • handling runtime warnings that could end badly in draw method (example: transforming a zero in log scale)
  • Annotations/pickle bugfix: a QString (instead of unicode) was pickled for annotation title, hence leading to compatiblity issues with PyQt API v2
  • guiqwt.io.array_to_dicomfile: fixed value representation error for smallest/largest pixel value parameters
  • guiqwt.resizedialog.is_edit_valid: fixed compatibility issue with PyQt API v2

  • baseplot: added method 'copy_to_clipboard' + tools: added CopyToClipboardTool (copy canevas window to clipboard)

Version 2.1.4

Since this version, guiqwt is compatible with PyQt4 API #1 and API #2. Please read carefully the coding guidelines which have been recently added to the documentation.

Bug fixes:

  • Sift/bugfix: difference/division operations were performed backwards (s001-s000 instead of s000-s001)
  • Sift: working directory is now changed after opening/saving signal/image
  • label.RangeComputation: fixed bug if compute function was returning more than one result and when X-range was empty (e.g. selection is outside curve X-axis values)
  • curve.CurvePlot: fixed pan/zoom erratic behavior for curves associated with log-scale axes
  • baseplot.BasePlot: now performing an autoscale after changing axis lin/log scale (set_axis_scale/set_scales)
  • annotations.AnnotatedSegment/CRITICAL: fixed an error (introduced in v2.1.0) when computing segment length (returned length was twice lower than the real value)
  • image.XYImageItem (Contributor: Carlos Pascual): fixed bug when Y-axis array is of dimension Ni+1 (where Ni is the number of rows of the image pixel data array)
  • Fixed compatiblity issues with PyQt v4.4 (Contributor: Carlos Pascual)
  • (minor) Fixed label text (too long) of 2D-Histogram items background color in shown DataSet
  • guiqwt.io.array_to_dicomfile/bugfix: Smallest/LargestImagePixelValue fields had wrong type (str instead of int)

  • tools.ImageStatsTool/bugfix: image title was not shown
  • CurvePlot: autoscale for log scales / bugfix: handling zero values
  • tools.AxisScaleTool/bugfix: when updating its status, the tool was setting the axes scales even when not necessary, hence causing an autoscale since changeset 1159 (687e22074f8d)
  • ItemCenterTool was not working as expected when centering annotated shapes having a specific transform matrix
  • XYImageItem objects: re-added cross-section support (removed accidently)
  • Curve autoscale method (curve.CurvePlot/ErrorBarCurvePlot):
    • now handles non-finite values (NaNs and infs)
    • logarithmic scales: now excludes zero/negative values to avoid confusing the autoscale algorithm

Possible API compatibility issues:

  • Moved functions from guiqwt.io to new module guiqwt.qthelpers: exec_image_save_dialog, exec_image_open_dialog, exec_images_open_dialog
  • Markers:
    • label and constraint callbacks take now 2 arguments (the marker's coordinates) instead of 3
    • removed method 'move_point_to': use new method 'set_pos' instead (takes two arguments: x, y)
  • Removed cursors introduced in v2.1.0:

    • Removed signals.SIG_CURSOR_MOVED, shapes.HorizontalCursor, shapes.VerticalCursor, annotations.AnnotatedHCursor, annotations.AnnotatedVCursor and associated builder methods (annotated_vcursor, annotated_hcursor)
    • Builder methods vcursor and hcursor were slightly changed (see tests/cursors.py to adapt your code)
    • Use markers instead of cursors (and SIG_MARKER_CHANGED instead of SIG_CURSOR_MOVED -- arguments are not identical, see signals.py):
      • base object: shapes.Marker
      • associated builder methods: marker, vcursor, hcursor, xcursor (see tests/cursors.py)
  • label.LabelItem: renamed method 'set_position' to 'set_pos' (consistency with shapes.PointShape, ...)
  • Annotations:
    • method get_center now returns coordinates without applying the transform matrix, i.e. in pure plot coordinates
    • the following methods were renamed to highlight the fact that the transform matrix is applied in those computations:
      • get_center was renamed to get_tr_center
      • get_size was renamed to get_tr_size
      • get_angle was renamed to get_tr_angle
      • get_diameter was renamed to get_tr_diameter

Version 2.1.0

Bug fixes:

  • cross_section: CrossSectionWidget.update_plot argument 'obj' was not optional as in CrossSectionPlot.update_plot
  • Contrast adjustment panel: when setting range (i.e. possible change of image data), levels histogram was not updated
  • Tests: handling I/O errors occuring when user has no write permission on current directory
  • Image items: bugfixes in ImageItem (scale issues: replaced x0,y0,dx,dy by xmin,xmax,ymin,ymax) + added intermediate class RawImageItem (ImageItem without scale)
  • Image module: fixed pixel alignment issues (get_closest_indexes, ...)
  • TrImageParam: fixed wrong class inheritance
  • LegendBoxItem/bugfix: missing argument for include_item
  • guiqwt.image.get_filename: bugfix when filename is None
  • ErrorBarCurveItem.set_data: now accepts None for both dx and dy (interface consistency with its parent class, CurveItem)
  • Image items/Align rectangular shape to image pixels/bugfix: this feature was not working for scaled images (ImageItem, MaskImageItem, ...)
  • guiqwt.curve/image: improved autoscale method (now works with curves plotted on two different Y-axes)
  • guiqwt.image: fixed issues related to empty filename/data when pickling/unpickling items
  • OpenFileTool: now remembers the previously browsed directory
  • Fixed PyQt >=v4.8 compatibility issue: PyQt is less permissive with signal string syntax (PyQt_PyObject is mandatory for passing a Python/C++ object)
  • guiqwt.fit: fixed rounding error due to slider's non-continuous behaviour
  • guiqwt.label/bugfix: text label was reset to '' when redrawn
  • guiqwt.fit: bugfixes when using logscale
  • guiqwt.io.array_to_imagefile/text files: format is now '%d' for integer data types
  • (Fixes Issue 7) guifit: standard fit boundary excludes rightmost value
  • guiqwt/curve.py: added workaround to avoid division by zero when clicking between curves
  • guiqwt/io.py-array_to_dicomfile: fixed ambiguous VR for PixelData when changing DICOM data (forced to 'OB')
  • Bugfix: recent versions of PyQt don't like the QApplication reference to be stored in modules (why is that?)
  • Annotation/get_infos: fixed unicode error occuring with py2exe distribution only

Possible API compatibility issues:

  • Panel interface: added mandatory method 'configure_panel' which is called just before adding the very first tool to the manager
  • baseplot: renamed guiqwt.baseplot.EnhancedQwtPlot to BasePlot

Other changes:

  • Cross sections/apply lut option turned on: now clipping data between 0 and LUT_MAX (0-1023), as it is done for displayed data
  • Added RGBImageItem
  • Scaler extension: added support for boolean arrays (e.g. for showing masks)
  • Added DeleteItemTool (add an entry "Remove" in plot item context menu)
  • Plot items/introduced notion of "private items": new item methods: (is_private, set_private), new plot methods: (get_private_items, get_public_items)
  • BaseImageItem.get_closest_indexes (+code refactoring): added argument 'corner' -> see new method 'get_closest_index_rect'
  • Shapes/Annotations: code cleaning/refactoring + implemented 'get_rect' method for EllipseShape
  • Tools deriving from InteractiveTool: added arguments 'title', 'icon' and 'tip' to customize the tool's action
  • MaskedImageItem: added ImageMaskTool to edit image's mask interactively
  • ShapeParam: added attributes "private" and "readonly"
  • interfaces.IBasePlotItem: added argument 'ctrl=None' to 'move_local_point_to' (ctrl is True when 'Ctrl' button is pressed)
  • Ellipse/Circle shapes: when pressing 'Ctrl' button while resizing the shape, its center position will remain unchanged
  • guiqwt.plot: added classes CurveWindow/ImageWindow (derived from QMainWindow)
  • Added transitional package guiqwt.transitional (regroup all Qwt5 import statements)
  • BasePlot: added class attributes AXIS_IDS, AXIS_NAMES (removed AXES)
  • BasePlot: added methods 'set_axis_limits' and 'get_axis_limits'

  • Panel widgets are now dockable
  • guiqwt.fit: code cleaning/refactoring + added FitWidget (similar to FitDialog but inherits directly from QWidget)
  • guiqwt.fit: fit params may now be changed as often as needed (the param widgets are reconstructed then)
  • guiqwt.fit: replaced set_fit_func and set_fit_params by set_fit_data (non sense to be setting one without the other)
  • Added vertical/horizontal cursor plot items (+ tools + cursor info label): see builder.make.vcursor, hcursor and info_cursor
  • Cross section panel: added button "auto refresh" (enabled by default) (e.g. may be disabled for large images)
  • Added signal SIG_MASK_CHANGED, emitted by plot when an image mask has changed
  • guiqwt.fit.FitWidget/FitDialog: now working with no fit param
  • guiqwt.signals.SIG_ITEM_REMOVED is now emitted by plot when an item is removed from the item list panel (as before) or using the delete item tool (new)

  • guiqwt.fit: added option 'param_cols' to regroup N fit parameters on each row
  • SnapshotTool: added options to add images together (instead of the default replace behavior) + bugfixes
  • Renamed signal_app.py to sift.py (Sifia -> Sift)
  • Sift: added support for image processing
  • Image levels histogram (contrast panel): replaced the 'remove first bin' feature by an intelligent Y-axis scaling
  • guifit: reorganized layout to gain some space + added option 'size_offset' to change param label's size
  • guiqwt.plot.CurveDialog: added attribute 'button_box' (reference to the QDialogButtonBox instance)
  • guiqwt.io: added open/save filedialog filters 'IMAGE_LOAD_FILTERS' (types supported by 'imagefile_to_array') and 'IMAGE_SAVE_FILTERS' (types supported by 'array_to_imagefile')
  • guiqwt.io: added support for "I;16B" images
  • Sift/added image operations (+ various bugfixes/enhancements): resize and rotate (90°, -90°, H/V flipping, arbritrarily rotation)
  • Sift: added run scripts + py2exe setup script + icon
  • PanelWidget: added class attributes PANEL_TITLE and PANEL_ICON
  • guiqwt.cross_section.CrossSectionItem: added method 'process_curve_data' (called when cross section data has changed instead of calling 'set_data' directly)
  • Tools: added 'toolbar_id' argument to all tools deriving from CommandTool
