    - #### setUseMatrixFilter

          public void setUseMatrixFilter(java.lang.Boolean useMatrixFilter)
                                  throws java.lang.IllegalStateException

      Configures whether a Matrix filter is used to render this DrawImage in Internet Explorer 6-8.

      With the default of `null`, matrix filters may be used unless `neverUseFilters` has been set. When set explicitly to `true`, matrix filters may be used even if `neverUseFilters` is `true`.

      This setting exists due to platform limitations in Internet Explorer where it is impossible to implement shearing transforms on an image without a matrix filter. Shear can arise by:

      - specifying a nonzero `xShearFactor` or `yShearFactor`,
      - specifying a nonuniform `scale` (where the scale values along the x- and y-dimensions are not equal) and a nonzero `rotation`, or
      - using `KnobType.RESIZE` `control knobs` on a rotated DrawImage.
      When prohibited from using a matrix filter, DrawImage will ignore the shearing components of its local transform. If any of the above conditions are met then the DrawImage might not be drawn correctly. Setting `useMatrixFilter` to `true` avoids this possibility but it also suffers from a range of side-effects mentioned `here`.
      Parameters:
        `useMatrixFilter` - Default value is null
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created
      See Also:
        `IEFilters overview and related methods`

    - #### getUseMatrixFilter

          public java.lang.Boolean getUseMatrixFilter()

      Configures whether a Matrix filter is used to render this DrawImage in Internet Explorer 6-8.

      With the default of `null`, matrix filters may be used unless `neverUseFilters` has been set. When set explicitly to `true`, matrix filters may be used even if `neverUseFilters` is `true`.

      This setting exists due to platform limitations in Internet Explorer where it is impossible to implement shearing transforms on an image without a matrix filter. Shear can arise by:

      - specifying a nonzero `xShearFactor` or `yShearFactor`,
      - specifying a nonuniform `scale` (where the scale values along the x- and y-dimensions are not equal) and a nonzero `rotation`, or
      - using `KnobType.RESIZE` `control knobs` on a rotated DrawImage.

                              java.lang.Integer height)

      Updates the drawImage to match the specified coordinates and size in `local coordinates`.
      Parameters:
        `left` - new left coordinate
        `top` - new top coordinate
        `width` - new width
        `height` - new height

    - #### setDefaultProperties

          public static void setDefaultProperties(DrawImage drawImageProperties)

      Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

      Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

      Parameters:
        `drawImageProperties` - properties that should be used as new defaults when instances of this class are created
      See Also:
        `SGWTProperties`

      Getter implementing the `LogicalStructure` interface, which supports Eclipse's logical structure debugging facility.
      Specified by:
        `getLogicalStructure` in interface `LogicalStructure`
      Overrides:
        `getLogicalStructure` in class `DrawItem`
