      public ClientImageData(FontIconDefinition fontIcon)
      Creates a new instance for font icons.

    • ClientImageData

      public ClientImageData(SVGInfo svgInfo)

    • ClientImageData

      public ClientImageData(String resource, String alt, int width, int height)
      Creates a new instance for single-images.

    • ClientImageData

      public ClientImageData(String resource, String alt, int width, int height, int imageWidth, int imageHeight, int offsetX, int offsetY)
      Creates a new instance for multiple-images.

  • Method Details

    • addSingle

      public void addSingle(String resource, int matchMask)
      Adds a single image.

    • addMulti

      public void addMulti(String resource, int matchMask, int offsetX, int offsetY)
      Adds a multiple image.

    • createSingleResolution

      public ClientImageData createSingleResolution(double dpr, String resource, int imageWidth, int imageHeight)
      Creates a new resolution for a single image.

    • createMultiResolution

      Commits this definition for no further changes to be used in transactions.

    • unCommit

      public void unCommit()
      Uncommits the ClientImageData to enable it e.g. to have a new DPR resolution added. The previously committed data remains until a new commit() is performed.

    • append

      public void append(PropMgr propertyManager, SendTransaction trans, double dpr)
      Appends the image data to a transaction for the specified device pixel ratio.
      Parameters:
      propertyManager - The property manager.
      trans - The transaction.
      dpr - The display pixel ratio on the client device.

    • appendNoData

      public static void appendNoData(SendTransaction trans)
      Method to call when no ClientImageData is present and needs to be sent to client.
      Parameters:
      trans - The transaction.

      Gets the default image resource string.
      Returns:
      The resource, or null for none.

    • adjustTo

      public ClientImageData adjustTo(double dpr)
      Find best match, i.e. the exact match first, otherwise the one that is just larger in DPR.
      Parameters:
      dpr - The device pixel ratio.
      Returns:
      The ClientImageData to use for the DPR, or "this" if no match was found.

    • isBitmap

      public boolean isBitmap()
      Returns if the image is a bitmap image type.

    • isFontIcon

      Returns if the image is a font icon image type.

    • isSVG

      public boolean isSVG()
      Returns if the image is SVG.

    • getKStringNonBitmap

      public String getKStringNonBitmap(KStringHTMLImageTag source, IKStringInfoProvider provider)
      Appends the font icon or SVG definition to a KString tag.
      Parameters:
      source - The source KString tag.
      provider - The information provider.
      Returns:
      The string to use.

    • getSVGString

      public String getSVGString(double cx, double cy)
      If the image is an SVG, the returned, perhaps scaled SVG image.
      Parameters:
      cx - Requested scaled width if larger than zero.
      cy - Requested scaled height if larger than zero.
      Returns:
      The SVG string, or null for failure or it's not an SVG image.
