Usage examples:
IMAGINGJAVA-1085 SVG to EMF Conversion
Please unpack archive - input.zip. Change value of varible basePath in code to the unpacked folder. execute follow code:
String[] testFiles = new String[]
{
"input.svg",
"juanmontoya_lingerie.svg",
"rg1024_green_grapes.svg",
"sample_car.svg",
"tommek_Car.svg"
};
String basePath = "C:\\Errors\\IMAGINGJAVA-1085\\";
String outputPath = basePath + "output\\";
File dir = new File(outputPath);
if (!dir.exists())
{
assert dir.mkdirs() : "Can not create output directory!";
}
for (String fileName : testFiles)
{
String inputFileName = basePath + fileName;
String outputFileName = outputPath + fileName + ".emf";
final Image image = Image.load(inputFileName);
try
{
image.save(outputFileName,
new EmfOptions()
{{
setVectorRasterizationOptions(new SvgRasterizationOptions()
{{
setPageSize(Size.to_SizeF(image.getSize()));
}});
}});
}
finally
{
image.close();
}
}IMAGINGJAVA-1092 PSD ignore alpha channel option doesn’t work without a license
// Reset license to Evaluated
License lic = new License();
lic.setLicense("");
String sourceFileName = "alphachannel(2).psd";
PsdImage image =
(PsdImage)
Image.load(
sourceFileName,
new PsdLoadOptions()
{{
setReadOnlyMode(true);
setIgnoreAlphaChannel(true);
}});
try
{
image.save("result.jpg", new JpegOptions());
}
finally
{
image.close();
}IMAGINGJAVA-1091 Gif Image saving failed
String dir = "C:\\Errors\\IMAGINGJAVA-1091\\";
GifImage gifImage = (GifImage)Image.load(dir + "XmpData_0.gif");
try
{
TiffOptions saveOptions = new TiffOptions(TiffExpectedFormat.TiffNoCompressionRgba);
saveOptions.setCompression(TiffCompressions.Lzw);
saveOptions.setImageWidth(gifImage.getWidth());
saveOptions.setImageLength(gifImage.getHeight());
saveOptions.setResolutionSettings(new ResolutionSetting(gifImage.getHorizontalResolution(), gifImage.getVerticalResolution()));
gifImage.save(dir + "XmpData_0.tif", saveOptions);
}
finally
{
gifImage.close();
}IMAGINGJAVA-1090 Dicom file loses color when converted to BMP
String dir = "C:\\Errors\\IMAGINGJAVA-1090\\";
Image gifImage = Image.load(dir + "input.dcm");
try
{
gifImage.save(dir + "output.bmp", new BmpOptions());
}
finally
{
gifImage.close();
}IMAGINGJAVA-1089 Improve Jpeg DCT encoder performance
Please take a big PNG image big.png and use the following code to convert that to JPEG:
public void TestJira3087_BigPngToJpeg()
{
String dir = "C:\\Errors\\IMAGINGJAVA-1089\\";
long startTm = System.nanoTime();
Image gifImage = Image.load(dir + "big.png");
try
{
gifImage.save(dir + "big.jpg", new JpegOptions());
}
finally
{
gifImage.close();
}
long endTm = System.nanoTime();
System.out.format("**** Conversion %s to %s takes %f ms.", "big.png", "big.jpg",
(endTm - startTm) / 1000000f);
}The average running time on my PC is about 40.273 sec. for v18.8 and 39.622 sec. with optimization.
Please take a big TIFF image tiff and use the following code to convert it to JPEG:
public void TestJira3087_BigTiffToJpeg()
{
String dir = "C:\\Temp\\Errors\\IMAGINGJAVA-1089\\";
long startTm = System.nanoTime();
Image gifImage = Image.load(dir + "FullImage.tiff");
try
{
gifImage.save(dir + "FullImage.jpg", new JpegOptions());
}
finally
{
gifImage.close();
}
long endTm = System.nanoTime();
System.out.format("**** Conversion %s to %s takes %f ms.", "FullImage.tiff", "FullImage.jpg",
(endTm - startTm) / 1000000f);
}The average running time on my PC is about 3.342 sec. for v18.8 and 3.335 sec. with optimization.
IMAGINGJAVA-1088 SVG is not converted to PDF
Image image = Image.load("test.svg");
try
{
PdfOptions pdfOptions = new PdfOptions();
SvgRasterizationOptions svgRasterizationOptions = new SvgRasterizationOptions();
svgRasterizationOptions.setPageSize(Size.to_SizeF(image.getSize()));
pdfOptions.setVectorRasterizationOptions(svgRasterizationOptions);
image.save("test.pdf", pdfOptions);
}
finally
{
image.close();
}IMAGINGJAVA-1086 TIFF throws exception during saving
Image image = Image.load("Fig 1 Location map.tiff");
try
{
image.save("out.tiff", new TiffOptions(TiffExpectedFormat.TiffLzwRgb));
}
finally
{
image.close();
}IMAGINGJAVA-1075 Dashed lines appear as solid in saved SVG
Image image = Image.load("image32.emf");
try
{
EmfRasterizationOptions emfRasterizationOptions = new EmfRasterizationOptions();
emfRasterizationOptions.setPageSize(Size.to_SizeF(image.getSize()));
SvgOptions svgOptions = new SvgOptions ();
svgOptions.setVectorRasterizationOptions(emfRasterizationOptions);
image.save("image32.emf.svg", svgOptions);
}
finally
{
image.close();
}IMAGINGJAVA-1043 Option for setting locale in application
Firstly, catch the error
Locale.setDefault(Locale.forLanguageTag("en-KR"));
// Now set default locale, it must be locale that define the language and country both
CurrentThreadSettings.setLocale("ko_KR");
EmfRecorderGraphics2D graphics = new EmfRecorderGraphics2D(
new Rectangle(0, 0, 1000, 1000), new Size(1000, 1000),
new Size(100, 100));
Pen pen = new Pen(Color.getRed()); // RED color
graphics.drawLine(pen, 1, 1, 50, 50);
EmfImage image = graphics.endRecording();
// Here we caught the error because of unsupported locale, moreover this code corrupt data of internal structures and after that nothing will work until restart.
try
{
image.save("test_pen.emf", new EmfOptions());
}
finally
{
image.close();
}Secondly there will be no error.
Locale.setDefault(Locale.forLanguageTag("en-KR"));
// Now set default locale, it must be locale that define the language and country both
CurrentThreadSettings.setLocale("ko_KR");
EmfRecorderGraphics2D graphics = new EmfRecorderGraphics2D(
new Rectangle(0, 0, 1000, 1000), new Size(1000, 1000),
new Size(100, 100));
Pen pen = new Pen(Color.getRed()); // RED color
graphics.drawLine(pen, 1, 1, 50, 50);
EmfImage image = graphics.endRecording();
// Now, there is no error!
try
{
image.save("test_pen.emf", new EmfOptions());
}
finally
{
image.close();
}IMAGINGJAVA-1024 Exception on converting image
Image image = Image.load("image75.emf");
try
{
EmfRasterizationOptions emfRasterizationOptions = new EmfRasterizationOptions();
emfRasterizationOptions.setPageSize(Size.to_SizeF(image.getSize()));
SvgOptions svgOptions = new SvgOptions ();
svgOptions.setVectorRasterizationOptions(emfRasterizationOptions);
image.save("image75.emf.svg", svgOptions);
}
finally
{
image.close();
