Usage Examples:
IMAGINGJAVA-8194 Incorrect extracting embedded bmp from Cdr image
try (Image image = Image.load("D:\\test.cdr"))
{
EmbeddedImage[] bmp_image = ((VectorImage) image).getEmbeddedImages();
int i = 0;
for (EmbeddedImage im : bmp_image)
{
try
{
im.getImage().save(String.format("D:\\Cdr_image%d.bmp", i++));
}
finally
{
im.close();
}
}
}
IMAGINGJAVA-8193 Incorrect saving Dicom image
try (DicomImage image = (DicomImage)Image.load("IMG-0002-00007.dcm"))
{
image.save("IMG-0002-00007.dcm.dcm");
}
IMAGINGJAVA-8192 Review error messages in the entire library
Proper exception message example:
// invalid CDR with no pages
try (Image image = Image.load("city-auto-skf_2.cdr"))
{
// do something
}
catch (RuntimeException e)
{
// check if error is happened because the image has no pages
String correctMessage = "CDR document contains no pages.";
if (!e.getCause().getMessage().equals(correctMessage))
{
throw e;
}
}
IMAGINGJAVA-8191 Implement Jpeg saved quality estimation
try (JpegImage image = (JpegImage)Image.load("cat.jpg"))
{
boolean isNotDefaultQuality = image.getJpegOptions().getQuality() != 75;
}
IMAGINGJAVA-8187 Can’t load PNG image
try (Image image = Image.load("input.png", new LoadOptions {{ setDataRecoveryMode(DataRecoveryMode.ConsistentRecover); }}))
{
image.save("output.png");
}
IMAGINGJAVA-8186 SVG image Load method throws an exception
try (Image img = Image.load("new_black_2.svg");)
{
System.out.println(img.getSize());
}
IMAGINGJAVA-8184 Can’t convert WMZ to PNG
Now WMZ export to raster PNG format works properly:
try (Image image = Image.load("image.wmz"))
{
PngOptions options = new PngOptions();
options.setVectorRasterizationOptions(new WmfRasterizationOptions()
{{
setPageHeight(image.getHeight());
setPageWidth(image.getWidth());
}});
image.save("result.png", options);
}
IMAGINGJAVA-8182 Problem in EMF to SVG conversion
String baseFolder = "D:\\";
String file = "J_ORD042-I_0011.emf";
String inputFileName = baseFolder + file;
String outputFileName = inputFileName + ".svg";
try (Image image = Image.load(inputFileName))
{
image.save(outputFileName, new SvgOptions());
}
IMAGINGJAVA-8181 Artifacts appear when load tiff file and save to tiff with parameters
try (RasterImage image = (RasterImage) Image.load("input.tiff"))
{
XmpPacketWrapper xmp = image.getXmpData();
if (xmp == null)
{
XmpHeaderPi xmpHeader = new XmpHeaderPi(UUID.randomUUID().toString());
XmpTrailerPi xmpTrailer = new XmpTrailerPi(true);
XmpMeta xmpMeta = new XmpMeta();
xmp = new XmpPacketWrapper(xmpHeader, xmpTrailer, xmpMeta);
image.setXmpData(xmp);
}
if (xmp.containsPackage("dc"))
{
for (XmpPackage xmpPackage : xmp.getPackages())
{
if (xmpPackage.getNamespaceUri().trim().equalsIgnoreCase("http://purl.org/dc/elements/1.1/"))
{
if (xmpPackage.containsKey("dc:keywords"))
{
xmpPackage.set_Item("dc:keywords", "2021");
}
else
{
xmpPackage.addValue("dc:keywords", "2021");
}
}
}
}
else
{
XmpBasicPackage xmpPackage = new XmpBasicPackage("dc", "http://purl.org/dc/elements/1.1/");
xmpPackage.addValue("dc:keywords", "2021");
xmp.addPackage(xmpPackage);
}
image.save("output.tiff", new TiffOptions(TiffExpectedFormat.TiffLzwRgba));
}
IMAGINGJAVA-8180 Incorrect export BMP -> JPG -> PNG
Correct BMP -> JPEG -> PNG export example:
try (Image bmp = Image.load("bmp-image.bmp"))
{
try (ByteArrayOutputStream jpegStream = new ByteArrayOutputStream())
{
bmp.save(jpegStream, new JpegOptions()
{{
setColorType(JpegCompressionColorMode.Rgb);
}});
try (Image jpeg = Image.load(new ByteArrayInputStream(jpegStream.toByteArray())))
{
jpeg.save("bmp-to-jpeg-to-png.png", new PngOptions()
{{
setColorType(PngColorType.TruecolorWithAlpha);
setProgressive(true);
}});
}
}
}
IMAGINGJAVA-8178 Cannot export particular EPS image
try (Image image = Image.load("test.eps"))
{
image.save("output.png", new PngOptions());
}
