Usage Examples:

IMAGINGNET-3623 QA 19.11 .NET 3549 Opaque parts

using (Image image = Image.Load("sample_car.svg"))  
{  
 image.Resize(image.Width \* 2, image.Height \* 2);  
 image.Save("sample_car_resize_2_2.png", new PngOptions());  
}

IMAGINGNET-2548 Introduce new classes for vector and multi page images

 

  1. Abstract class VectorImage introduced. And All vector images in the library are inherited from this class. Whereas bitmap images are inherited from RasterImage. That allows you to uniquely separate raster and vector images.
    For example:
using (Image image = Image.Load(fileName))  

{  

if (image is VectorImage)  

{  

...  

}

else

{  

...  

}

}

 The IMultipageImage interface has been introduced, thanks to which you can determine whether the image contains layers/pages/ frames. All multi-page images such as PSD, CDR, GIF, etc. are descendants of this interface. Thanks to the Pages property, you can access the pages of any multi-page image in the library.

For example:

using (Image image = Image.Load(fileName))  
{  
    if (image is IMultipageImage)  
    {  
         var pages = ((IMultipageImage)image).Pages;  
    }  
}

2.Export has been improved; exporting multi-page images has become easier thanks to the MultiPageOptions option. With this option you can specify the pages that you want to export to another format. In the case of export to a single-page format, the 1st page of the range will be exported; in the case of export to a multi-page format, all pages of the range will be exported.
3.1. Example of export from multi-page format to single-page:

int startPage = 3;  
int countPage = 2;  
using (Image image = Image.Load(fileName))  
{  
PngOptions pngOptions = new PngOptions();  
pngOptions.MultiPageOptions = new MultiPageOptions(new IntRange(startPage,
countPage));  
image.Save(outFileName, pngOptions);  
}

Here, the one 4th page will be exported. Png is a single-page format. And page counting is done from scratch.

3.2. Export from multi-page format to multi-page

 int startPage = 0;

 int countPage = 2;

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

 {

     TiffOptions tiffOptions = new
TiffOptions(TiffExpectedFormat.TiffDeflateRgb);

     tiffOptions.MultiPageOptions = new MultiPageOptions(new IntRange(startPage,
countPage));

     image.Save(outFileName, tiffOptions);

 }

Here the 4th and 5th pages will be exported to the tiff format

Please add export method:

private void ExportImage(ImageOptionsBase imageOptions, string ext)  
{

string baseFolder = "D:\\\\images";  
string inputFolderName = baseFolder;  
string outputFolderName = Path.Combine(baseFolder, "out");  
string[] files = Directory.GetFiles(inputFolderName, "\*.\*");  
foreach (string inputFileName in files)  
{

Console.WriteLine(Path.GetFileName(inputFileName));

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

//export only 2 pages  
if (image is IMultipageImage && ((IMultipageImage)image).Pages != null &&
((IMultipageImage)image).PageCount \> 2)  
{  
imageOptions.MultiPageOptions = new MultiPageOptions(new IntRange(0, 2));  
}  
else  
{  
imageOptions.MultiPageOptions = null;  
}

 

if (image is VectorImage)  
{  
imageOptions.VectorRasterizationOptions =
(VectorRasterizationOptions)image.GetDefaultOptions(new object[] { Color.White,
image.Width, image.Height  });  
imageOptions.VectorRasterizationOptions.TextRenderingHint =
TextRenderingHint.SingleBitPerPixel;  
imageOptions.VectorRasterizationOptions.SmoothingMode = SmoothingMode.None;  
}

 

string outFileName = Path.Combine(outputFolderName,
Path.GetFileName(inputFileName) + ext);  
image.Save(outFileName, imageOptions);

}

}

}

and execute this code for cross formats export:

ImageOptionsBase[] imageOptions = new ImageOptionsBase[] {new PsdOptions(), new
WebPOptions(), new GifOptions(), new TiffOptions(TiffExpectedFormat.Default),
new BmpOptions(), new JpegOptions(), new Jpeg2000Options(), new PngOptions(),
new EmfOptions(), new SvgOptions(), new WmfOptions(), new PdfOptions(), };

string[] imageExt = new string[] {".psd", ".webp", ".gif", ".tiff", ".bmp",
".jpeg", ".j2k", ".png", ".emf", ".svg", ".wmf",".pdf"};

if (imageOptions.Length != imageExt.Length)  
{  
throw new Exception("imageOptions length not equal imageExt length");  
}

 for (int i = 0; i \< imageOptions.Length; i++)  
{  
this.ExportImage(imageOptions[i], imageExt[i]);  
}

Result images in this archive: output.zip

*In the case of exporting a multipage format to a onrpage, the 1st page is exported, unless others are specified in MultipageOptions.
*In case of exporting the GIF format to other formats, all frames except the first one can be partially displayed since full frame is obtained by overlay.

IMAGINGNET-3624 Support different raster data types in TIFF format

// below are 3 options for loading raw data

// Example 1. Loading raw data in accordance with its own raw data format.

// Example 2. Raw data loading according to user-specified raw data format.
// In this case, in addition, raw data is converted from its own format to the one specified by the user.
// Note that so far not all raw data formats can be converted to other formats (since not all color converters are still implemented and registered at the ColorConverterFactory).

using (RasterImage image = (RasterImage)Image.Load("input.tif"))
