IMAGINGNET-2572 Support for converting CMYK PSD to CMYK Tiff

Add to test project method:

 private void PsdToTiffCmyk(string folder, bool isIccProfile)

{

string fileName = string.Format("cmyk_{0}.tiff", isIccProfile);

string inputFile = Path.Combine(folder,"cmyk.psd");

string inputIccFile = Path.Combine(folder,"JapanWebCoated.icc");

string outputFile = Path.Combine(folder,fileName);

using (Image image = Image.Load(inputFile))

{

if (isIccProfile)

{

using (MemoryStream ms = new MemoryStream(File.ReadAllBytes(inputIccFile)))

{

image.Save(outputFile, new TiffOptions(TiffExpectedFormat.TiffLzwCmyk) { IccProfile = ms });

}

}

else

{

image.Save(outputFile, new TiffOptions(TiffExpectedFormat.TiffLzwCmyk));

}

}

}

execute following code:

 string folder = @"D:\tiff\";

//With IccProfile

this.PsdToTiffCmyk(folder,true);

//Without IccProfile

this.PsdToTiffCmyk(folder, false);

IMAGINGNET-2620 When PSD is converted to PNG, an ArgumentOutOfRangeException occurs [.Net]

 using (PsdImage input = (PsdImage)Image.Load("Cloud_AzPlat_Banner3A_SB_EN_US_160x600.psd"))

{

TextLayer textLayer;

foreach (Layer layer in input.Layers)

{

textLayer = layer as TextLayer;

if (textLayer != null)

{

textLayer.UpdateText("123\u0003abc");

}

}

input.Save("Cloud_AzPlat_Banner3A_SB_EN_US_160x600_updated.psd", new PsdOptions() { CompressionMethod = CompressionMethod.RLE });

}

using (PsdImage input = (PsdImage)Image.Load("Cloud_AzPlat_Banner3A_SB_EN_US_160x600_updated.psd"))

{

input.Save("Cloud_AzPlat_Banner3A_SB_EN_US_160x600_updated.png", new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });

}

IMAGINGNET-2619 Gif not properly converted to png

 string file = @"6.gif";

using (Image image = Image.Load(file))

{

image.Save(file + ".png", new PngOptions());

}

IMAGINGNET-2618 Exception on saving Tiff Image

 string sourceFilePath = "Carelogic-1-11082017-3016-CH.tif";

string outputFilePath = "Carelogic-1-11082017-3016-CH Out.tif";

int resolution = 96;

using (RasterImage image = (RasterImage)Image.Load(sourceFilePath))

{

TiffOptions saveOptions = new TiffOptions(TiffExpectedFormat.Default);

saveOptions.ResolutionSettings = new ResolutionSetting(resolution, resolution);

saveOptions.Compression = TiffCompressions.None;

saveOptions.BitsPerSample = new ushort[] { 1 };

int width = image.Width * resolution / (int)image.HorizontalResolution;

int height = image.Height * resolution / (int)image.VerticalResolution;

image.Resize(width, height); // No more exception here!

image.Save(outputFilePath, saveOptions);

}

IMAGINGNET-2617 Fix PSD test rendering for specific case

 using (PsdImage image = Image.Load("1.psd") as PsdImage)

{

image.Save("1.png", new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });

}

IMAGINGNET-2614 Fix PSD crop operation

 PsdLoadOptions psdLoadOptions = new PsdLoadOptions();

psdLoadOptions.LoadEffectsResource = true;

using (PsdImage image = (PsdImage)Image.Load("MSFT_DevEva_Web_Twitter-800x320_2-DVG.PSD", psdLoadOptions))

{

Rectangle rect = new Rectangle(10, 30, 100, 100);

image.Crop(rect);

image.Save("MSFT_DevEva_Web_Twitter-800x320_2-DVG_new_ethalon.png", new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });

}

IMAGINGNET-2612 Exception on converting emf to svg

 string file = @"powerpoint_emf.emf";

using (Image image = Image.Load(file))

{

EmfRasterizationOptions rasterizationOptions = new EmfRasterizationOptions();

rasterizationOptions.PageWidth = image.Width;

rasterizationOptions.PageHeight = image.Height;

image.Save(file + ".png", new PngOptions() { VectorRasterizationOptions = rasterizationOptions });

image.Save(file + ".svg", new SvgOptions() { VectorRasterizationOptions = rasterizationOptions });

}

IMAGINGNET-2610 Image saving failed when saving JPEG2000 as PNG

 string inputImage = @"D:\input.jp2";

string outputImage = @"D:\input.png";

using (Image image = Image.Load(inputImage))

{

image.Save(outputImage, new PngOptions());

}

IMAGINGNET-2596 Improve memory usage of Jpeg fomat through improving work with buffer

IMAGINGNET-2568 Image exception on load Tiff image

 string inputFileName = @"D:\posterUfficio_crop.tif";

string outFileName = @"D:\posterUfficio_crop.png";

using (Image image = Image.Load(inputFileName))

{

image.Save(outFileName, new PngOptions());

}

IMAGINGNET-2552 TypeTool6ResourceProcessor.ReplaceTextInGlobalResources does not work. Fix is related to saving PSD metadata after text update (part of it was just not saved), which can be checked by working with updated PSD file directly from Photoshop. If export to other format was the case for you, just don’t bother with it.

IMAGINGNET-2551 Incorrect number conversion in OpenDocument support class: OdEnhancedGeometryReader.ReadEnd.

 string inputFileName = @"D:\Odg\modifiersTest.odg";

string outputFileName = @"D:\Odg\modifiersTest.pdf";

ImageOptionsBase options = new PdfOptions();

System.Globalization.CultureInfo culture = System.Threading.Thread.CurrentThread.CurrentCulture;

System.Globalization.CultureInfo customCulture = (System.Globalization.CultureInfo)culture.Clone();

customCulture.NumberFormat.NumberDecimalSeparator = ",";

System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;

try

{

using (OdgImage image = (OdgImage) Image.Load(inputFileName))

{

this.ExportImage(image.Pages[0], outputFileName, options);

}

}

finally

{

System.Threading.Thread.CurrentThread.CurrentCulture = culture;

}

private void ExportImage(Image image, string fileName, ImageOptionsBase options)

{

options.VectorRasterizationOptions = new MetafileRasterizationOptions

{

PageWidth = image.Width,

PageHeight = image.Height

};

image.Save(fileName, options);

}

IMAGINGNET-2545 Gif image is not properly converted to Png

 string path = @"transbugs.gif";

using (Image m_oDocument = Image.Load(path))

{

int m_iResolution = 98;

Aspose.Imaging.ImageOptions.PngOptions OptionsIM = new Aspose.Imaging.ImageOptions.PngOptions();

OptionsIM.ColorType = Aspose.Imaging.FileFormats.Png.PngColorType.TruecolorWithAlpha;

Aspose.Imaging.ResolutionSetting oResIM = new Aspose.Imaging.ResolutionSetting(Convert.ToDouble(m_iResolution), Convert.ToDouble(m_iResolution));

OptionsIM.ResolutionSettings = oResIM;

((Aspose.Imaging.Image)m_oDocument).Save(path + ".png", OptionsIM);

}

IMAGINGNET-2527 Corrupted DngImage.Width and DngImage.Height after calling the Image.GetPixel method.

 int expectedWidth;

int expectedHeight;

string inputFilename = @"D:\berries-raw.dng";

string outFileName = @"D:\result.tiff";

using (DngImage image = (DngImage) Image.Load(inputFilename))

{

expectedWidth = image.Width;

expectedHeight = image.Height;

Color c = image.GetPixel(3303, 1787);

Console.WriteLine(c);

if (expectedWidth != image.Width)

{

throw new Exception(string.Format("Current file: Expected width = {0}, Actual width = {1}", expectedWidth, image.Width));

}

if (expectedHeight != image.Height)

{

throw new Exception(string.Format("Current file: Expected height = {0}, Actual height = {1}", expectedHeight, image.Height));

}

image.Save(

outFileName,

new TiffOptions(TiffExpectedFormat.TiffNoCompressionRgb));

}

using (Image image = Image.Load(outFileName))

{

if (expectedWidth != image.Width)

{

throw new Exception(string.Format("Result file: Expected width = {0}, Actual width = {1}", expectedWidth, image.Width));

}

if (expectedHeight != image.Height)

{

throw new Exception(string.Format("Result file: Expected height = {0}, Actual height = {1}", expectedHeight, image.Height));

}

}
