Image image = Image.load(filePath);

try

{

	if (!(image instanceof PsdImage))

	{

		return;

	}

	PsdImage psdImage = (PsdImage)image;

	Layer[] layers = psdImage.getLayers();

	for (int index = layers.length - 1; index >= 0; index--)

	{

		Layer layer = layers[index];

		if (!(layer instanceof TextLayer))

		{

			continue;

		}

		TextLayer textLayer = (TextLayer)layer;

		textLayer.updateText("\\()");

	}

	PsdOptions imageOptions = new PsdOptions(psdImage);

	psdImage.save(outputFilePath, imageOptions);

}

finally

{

	image.close();

		new Size(100, 100));

Pen pen = new Pen(Color.getRed());  // RED color

graphics.drawLine(pen, 1, 1, 50, 50);

EmfImage image = graphics.endRecording();

try

{

	// In final file you MUST see the RED line, not BLACK, please check it.

	image.save("test_pen.emf", new EmfOptions());

}

finally

{

	image.close();

}

IMAGINGJAVA-1058 Improve Jpeg DCT decoder performance.

 public void IMAGINGJAVA_1058()

{

	String dir = "C:\\Errors\\IMAGINGJAVA-1058\\";

	long startTime = System.nanoTime();

	resizeAspose(dir + "interleaved.jpg", dir + "interleaved.out.jpg", 300, 300);

	long msInterleaved = System.nanoTime() - startTime;

	startTime = System.nanoTime();

	resizeAspose(dir + "non-interleaved.jpg", dir + "non-interleaved.out.jpg", 300, 300);

	long msNonInterleaved = System.nanoTime() - startTime;

	System.out.format("**** Conversion %s takes %d ms.\n", "interleaved.jpg", msInterleaved / 1000000);

	System.out.format("**** Conversion %s takes %d ms.\n", "non-interleaved.jpg", msNonInterleaved / 1000000);

}

private static void resizeAspose(String inputPath, String outputPath, int desiredWidth, int desiredHeight)

{

	Image image = Image.load(inputPath);

	try

	{

		int originalWidth = image.getWidth();

		int originalHeight = image.getHeight();

		float percentWidth = (float)desiredWidth / (float)originalWidth;

		float percentHeight = (float)desiredHeight / (float)originalHeight;

		float percent = percentHeight < percentWidth ? percentHeight : percentWidth;

		int newWidth = Math.min((int)(originalWidth * percent), originalWidth);

		int newHeight = Math.min((int)(originalHeight * percent), originalHeight);

		image.resize(newWidth, newHeight, ResizeType.NearestNeighbourResample);

		image.save(outputPath);

	}

	finally

	{

		image.close();

	}

}

I’ve got the following result: v18.7 Conversion interleaved.jpg takes 2348 ms. Conversion non-interleaved.jpg takes 908 ms.

Optimized Conversion interleaved.jpg takes 1296 ms. Conversion non-interleaved.jpg takes 437 ms.

So the execution time was reduced almost twice after optimization.

IMAGINGJAVA-1027 EMF file not properly converted to SVG

 String baseFolder = "C:\\IMAGINGNET-3048\\";

String fileName = "image39.emf";

String inputFileName = baseFolder + fileName;

String outputFileName = baseFolder + fileName + ".svg";

Image image = Image.load(inputFileName);

try

{

	EmfRasterizationOptions emfRasterizationOptions = new EmfRasterizationOptions();

	emfRasterizationOptions.setPageSize(Size.to_SizeF(image.getSize()));

	SvgOptions options = new SvgOptions();

	options.setVectorRasterizationOptions(emfRasterizationOptions);

	image.save(outputFileName, options);

}

finally

{

	image.close();

}

IMAGINGJAVA-1025 Color radiance issues in images

 String baseFolder = "C:\\IMAGINGJAVA-1025\\";

String fileName = "image34.emf";

String inputFileName = baseFolder + fileName;

String outputFileName = baseFolder + fileName + ".svg";

Image image = Image.load(inputFileName);

try

{

	EmfRasterizationOptions emfRasterizationOptions = new EmfRasterizationOptions();

	emfRasterizationOptions.setPageSize(Size.to_SizeF(image.getSize()));

	SvgOptions svgOptions = new SvgOptions();

	svgOptions.setVectorRasterizationOptions(emfRasterizationOptions);

	image.save(outputFileName, svgOptions);

}

finally

{

	image.close();
