Usage Examples:
IMAGINGJAVA-8895 Blank output image on converting TIFF
String inputPath = "input.tiff";
try (Image image = Image.load(inputPath))
{
image.save(inputPath + ".pdf");
}
IMAGINGJAVA-8894 Creating a PNG with BitDepth=16 throws an exception in evaluation mode
String outputPath = "output64Bit.png";
PngOptions createOptions = new PngOptions()
{{
setBitDepth(16);
setColorType(PngColorType.TruecolorWithAlpha);
setCompressionLevel(9);
setFilterType(PngFilterType.Sub);
setProgressive(true);
}};
License lic = new License();
lic.SetLicense(""); // no license
try (PngImage pngImage = new PngImage(createOptions, 100, 100))
{
Graphics graphics = new Graphics(pngImage);
LinearGradientBrush gradientBrush = new LinearGradientBrush(
new Point(0, 0),
new Point(pngImage.getWidth(), pngImage.getHeight()),
Color.getBlue(),
Color.getTransparent());
graphics.fillRectangle(gradientBrush, pngImage.getBounds());
pngImage.save(outputPath);
}
IMAGINGJAVA-8890 PNG to PDF: Temporary files not deleted
try (Image pngImage = Image.load("high_resolution_image.png"))
{
PdfOptions exportOptions = new PdfOptions();
pngImage.save("out".pdf, exportOptions);
}
IMAGINGJAVA-8884 Reduce memory usage during AVIF image loading.
### Example
The sample AVIF image is exported into a PNG image format. Compared to the previous version, processing speed has increased approximately 12 times, while memory usage has been reduced by about 20 times.
String inputPath = "input.avif";
String outputPath = "output.png";
try (AvifImage image = (AvifImage)Image.load(inputPath))
{
image.save(outputPath);
}
IMAGINGJAVA-8879 Fix bugs with rendering some characters in CDR format
try (Image image = Image.load("Test corel.cdr"))
{
image.save("result.png", new PngOptions()
{{
setVectorRasterizationOptions(new CdrRasterizationOptions()
{{
setPositioning(PositioningTypes.DefinedByDocument);
}});
}});
}
IMAGINGJAVA-8878 Some EXIF metadata props are missing after JPEG to TIFF
int imageOrientation = 0;
String inputPath = "input.jpeg";
try (Image image = Image.load(inputPath))
{
if (image instanceof IHasExifData)
{
IHasExifData hasExif = (IHasExifData) image;
if (hasExif.getExifData() != null)
{
imageOrientation = hasExif.getExifData().getOrientation();
}
}
image.save(inputPath + ".tiff",
new TiffOptions(TiffExpectedFormat.TiffJpegRgb)
{{
setKeepMetadata(true);
}});
}
int outputOrientation = 0;
try (Image image = Image.load(inputPath))
{
if (image instanceof IHasExifData)
{
IHasExifData hasExif = (IHasExifData) image;
if (hasExif.getExifData() != null)
{
outputOrientation = hasExif.getExifData().getOrientation();
}
}
}
assert imageOrientation == outputOrientation;
IMAGINGJAVA-8876 Conversion of PNG file from 8 bit per channel to 16 fails without a license
License lic = new License();
lic.SetLicense(""); // no license
try (Image image = Image.load("OutputAllTypes2.png"))
{
PngOptions options = new PngOptions()
{{
setBitDepth(16);
setColorType(PngColorType.TruecolorWithAlpha);
}};
image.save("OutputAllTypes2-64Bit.png", options);
}
IMAGINGJAVA-8869 Regression: EMF to PDF: Blank output file
try (Image image = Image.load("example.emf"))
{
EmfRasterizationOptions rasterOpts = new EmfRasterizationOptions();
rasterOpts.setPageWidth(image.getWidth());
rasterOpts.setPageHeight(image.getHeight());
rasterOpts.setBackgroundColor(Color.getWhiteSmoke());
PdfOptions pdfOptions = new PdfOptions();
pdfOptions.setVectorRasterizationOptions(rasterOpts);
image.save("emf_out.pdf", pdfOptions);
}
IMAGINGJAVA-8788 Error in image save without license
License lic = new License();
lic.setLicense(""); // no license
try (Image image = Image.load("OutputAllTypes2.png"))
{
PngOptions options = new PngOptions();
options.setBitDepth(16);
options.setColorType(PngColorType.TruecolorWithAlpha);
image.save("OutputAllTypes2-64Bit.png", options);
}
IMAGINGJAVA-8139 Incorrect conversion from EPS to PNG
try (Image image = Image.load("C3.eps"))
{
image.save("output.png", new PngOptions());
}
