Class SVGRenderingAccuracyTest

java.lang.Object

org.apache.batik.test.AbstractTest

org.apache.batik.test.svg.AbstractRenderingAccuracyTest

org.apache.batik.test.svg.SVGRenderingAccuracyTest

All Implemented Interfaces:

Test

Direct Known Subclasses:

PreconfiguredRenderingTest

public class SVGRenderingAccuracyTest
extends AbstractRenderingAccuracyTest

Checks for regressions in rendering a specific SVG document. The Test will rasterize and SVG document and compare it to a reference image. The test passes if the rasterized SVG and the reference image match exactly (i.e., all pixel values are the same).

Nested Classes

Modifier and Type	Class and Description
protected class	SVGRenderingAccuracyTest.InternalPNGTranscoder Inner class which derives from the PNGTranscoder and calls the manipulateSVGDocument just before encoding happens.

Field Summary

Fields

Modifier and Type	Field and Description
static String	ERROR_CANNOT_TRANSCODE_SVG Error when transcoding the SVG document generates an error {0} = URI of the transcoded SVG file {1} = Exception class {2} = Exception message {3} = Stack trace.
protected String	userLanguage The userLanguage for which the document should be tested.
protected boolean	validate Controls whether or not the SVG file should be validated.

Field Detail

ERROR_CANNOT_TRANSCODE_SVG

public static final String ERROR_CANNOT_TRANSCODE_SVG

Error when transcoding the SVG document generates an error {0} = URI of the transcoded SVG file {1} = Exception class {2} = Exception message {3} = Stack trace.

Constant Field Values

VALIDATING_PARSER

public static final String VALIDATING_PARSER

Validating parser class name

validate

protected boolean validate

Controls whether or not the SVG file should be validated. By default, no validation is used.

userLanguage

protected String userLanguage

The userLanguage for which the document should be tested.

Constructor Detail

SVGRenderingAccuracyTest

public SVGRenderingAccuracyTest(String svgURL,
                        String refImgURL)

Constructor.

Parameters:

svgURL - the URL String for the SVG document being tested.

refImgURL - the URL for the reference image.

SVGRenderingAccuracyTest

protected SVGRenderingAccuracyTest()

For subclasses

Method Detail

setValidating

public void setValidating(Boolean validate)

If true, this test will use validation

getValidating

public boolean getValidating()

setUserLanguage

public void setUserLanguage(String userLanguage)

Sets the userLanguage

getUserLanguage

public String getUserLanguage()

manipulateSVGDocument

protected Document manipulateSVGDocument(Document doc)

Template method which subclasses can override if they need to manipulate the DOM in some way before running the accuracy test. For example, this can be useful to test the alternate stylesheet support.

encode

public TestReport encode(URL srcURL,
                FileOutputStream fos)

Specified by:

encode in class AbstractRenderingAccuracyTest

getTestImageTranscoder

public ImageTranscoder getTestImageTranscoder()

Returns the ImageTranscoder the Test should use
