Version 6.1.0

Breaking Changes

  • GrapeCity.Documents.Svg.SvgMatrix class renamed to Matrix and moved to GrapeCity.Documents.Common namespace.

  • GrapeCity.Documents.Imaging.InterpolationMode enum has been moved to GrapeCity.Documents.Drawing namespace.

New Features and Improvements

  • Added GcGraphics.InterpolationMode property that gets or sets the sampling mode to use when drawing images with resizing.

  • Added GcGraphics.IsInterpolationModeSupported() method, which indicates whether the current graphics implementation supports a specified interpolation mode.

  • Added the following classes and enums to GrapeCity.Documents.Layout namespace that implements a flat layout model based on constraints. Instead of setting the exact position of a visual element, constraints define rules for how that position depends on the positions of other elements:

    • GrapeCity.Documents.Layout.LayoutHost class: Represents the host and origin of a coordinate system for LayoutView objects.

    • GrapeCity.Documents.Layout.LayoutView class: Represents a transformed surface with a set of LayoutRect objects.

    • GrapeCity.Documents.Layout.LayoutRect class: Represents a rectangle with constraints.

    • GrapeCity.Documents.Layout.AnchorPoint class: Represents a point to be used as an anchor.

    • GrapeCity.Documents.Layout.Contour class: Represents a closed figure on a LayoutView.

    • GrapeCity.Documents.Layout.LayoutException class: Represents an error that occurred when resolving constraints in a LayoutRect.

    • GrapeCity.Documents.Layout.Constraint class: The base class for LayoutRect constraints.

    • GrapeCity.Documents.Layout.AngleConstraint class: Determines the rotation angle of the target LayoutRect.

    • GrapeCity.Documents.Layout.AspectRatioConstraint class: Determines the aspect (width to height) ratio of the target LayoutRect.

    • GrapeCity.Documents.Layout.StarSizeConstraint class: Determines the proportional width or height (weight) of the target LayoutRect.

    • GrapeCity.Documents.Layout.SizeConstraint class: Restricts the width or height of the target LayoutRect.

    • GrapeCity.Documents.Layout.PositionConstraint class: Determines the position of the sides or centers of the target LayoutRect.

    • GrapeCity.Documents.Layout.ContourConstraint class: Determines the min/max position of sides relative to the contour.

    • GrapeCity.Documents.Layout.AnchorParam enum: Specifies the source parameter of the anchor LayoutRect.

    • GrapeCity.Documents.Layout.TargetParam enum: Specifies the target parameter of the constraint's target LayoutRect.

    • GrapeCity.Documents.Layout.ContourPosition enum: Specifies the position of the anchor for a contour constraint.

  • Added the following classes that use LayoutHost and related classes and enums to draw simple or complex tables with merged, rotated, auto-sized, multilayer cells with customizable styles:

    • GrapeCity.Documents.Drawing.TableRenderer class: A helper class for drawing tables on a GcGraphics (e.g., GcPdfGraphics or GcBitmapGraphics).

    • GrapeCity.Documents.Drawing.TableCell class: Represents the layout, style, and data of a table cell. Cells can contain simple text, multi-formatted TextLayout, or owner-drawn content.

    • GrapeCity.Documents.Drawing.FrameStyle class: Describes the inner border and filling of a table cell or table frame.

    • GrapeCity.Documents.Drawing.CellStyle class: Describes the relative position, inner border, filling, and layout of a table cell.

    • GrapeCity.Documents.Drawing.FrameBorders enum: Specifies which border lines are drawn in a table cell or table frame.

    • GrapeCity.Documents.Drawing.FixedTableSides enum: Specifies which sides of a table are fixed. The position of those sides does not depend on the table's content.

    • GrapeCity.Documents.Drawing.CellPosition enum: Specifies whether a table cell appears behind or on top of other cells.

  • The default encoding used by GcBitmap.SaveAsIco() changed from Argb32 to Png.

Resolved Issues

  • Miscellaneous minor big fixes.
