C# Resize EPS Description

Resizing the image is an operation that changes one of the, or both, dimensions of the image: width and height. The content of the image is left the same, but the image itself can be scaled in dependence of new values of width and height. If with and height are proportionally increased the representation of EPS image will be enlarged, otherwise it will be lessened. If width and height are changed disproportionately the resulting representation of EPS image will be compressed or elangated in some direction. The volume of the EPS file will remain almost unchanged as our solution doesnt’t work with the content but works with the header and the setup section of EPS file. To set up new size for the representation of EPS image often it is necessary to know its existing size and choise the units in which to assign new size. It can be Points (1/72 of inch), Inches, Millimeters, Centimeters and Percents. So the steps for resizing EPS image in C# follows:

1. Initialize PsDocument object with an input stream containing EPS file.
2. Extract existing size of the image using static method ExtractEpsSize.
3. Create an output stream for resulting EPS file.
4. Resize PsDocument object with new size in selected Units with static method ResizeEps.

Resize EPS setting new size in Points in C#

In the following C# code snippet new size of the image is set by Points (1/72 of inch):

// For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-.NET

// The path to the documents directory.
string dataDir = GetDataDir();

 //Create an input stream for EPS file
using (Stream inputEpsStream = new System.IO.FileStream(dataDir + "input.eps", System.IO.FileMode.Open, System.IO.FileAccess.Read))
{
    //Initialize PsDocument object with input stream
    PsDocument doc = new PsDocument(inputEpsStream);

    //Get size of EPS image
    Size oldSize = doc.ExtractEpsSize();

    //Create an output stream for resized EPS
    using (Stream outputEpsStream = new System.IO.FileStream(dataDir + "output_resize_inches.eps", System.IO.FileMode.Create, System.IO.FileAccess.Write))
    {
        //Save EPS to the output stream with new size assigned in inches
        doc.ResizeEps(outputEpsStream, new SizeF(oldSize.Width * 2, oldSize.Height * 2), Units.Points);
    }
}

Resize EPS setting new size in Inches in C#

In the following C# code snippet new size of the image is set by Inches:

// For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-.NET

// The path to the documents directory.
string dataDir = GetDataDir();

 //Create an input stream for EPS file
using (Stream inputEpsStream = new System.IO.FileStream(dataDir + "input.eps", System.IO.FileMode.Open, System.IO.FileAccess.Read))
{
    //Initialize PsDocument object with input stream
    PsDocument doc = new PsDocument(inputEpsStream);

    //Get size of EPS image
    Size oldSize = doc.ExtractEpsSize();

    //Create an output stream for resized EPS
    using (Stream outputEpsStream = new System.IO.FileStream(dataDir + "output_resize_inches.eps", System.IO.FileMode.Create, System.IO.FileAccess.Write))
    {
        //Save EPS to the output stream with new size assigned in inches
        doc.ResizeEps(outputEpsStream, new SizeF(5.791f, 3.625f), Units.Inches);
    }
}

Resize EPS setting new size in Millimeters in C#

In the following C# code snippet new size of the image is set by Millimeters:

// For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-.NET

// The path to the documents directory.
string dataDir = GetDataDir();

 //Create an input stream for EPS file
using (Stream inputEpsStream = new System.IO.FileStream(dataDir + "input.eps", System.IO.FileMode.Open, System.IO.FileAccess.Read))
{
    //Initialize PsDocument object with input stream
    PsDocument doc = new PsDocument(inputEpsStream);

    //Get size of EPS image
    Size oldSize = doc.ExtractEpsSize();

    //Create an output stream for resized EPS
    using (Stream outputEpsStream = new System.IO.FileStream(dataDir + "output_resize_mms.eps", System.IO.FileMode.Create, System.IO.FileAccess.Write))
    {
        //Save EPS to the output stream with new size assigned in millimeters
        doc.ResizeEps(outputEpsStream, new SizeF(196, 123), Units.Millimeters);
    }
}

Resize EPS setting new size in Percents in C#

In the following C# code snippet new size of the image is set by Percents:

// For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-.NET

// The path to the documents directory.
string dataDir = GetDataDir();

 //Create an input stream for EPS file
using (Stream inputEpsStream = new System.IO.FileStream(dataDir + "input.eps", System.IO.FileMode.Open, System.IO.FileAccess.Read))
{
    //Initialize PsDocument object with input stream
    PsDocument doc = new PsDocument(inputEpsStream);

    //Get size of EPS image
    Size oldSize = doc.ExtractEpsSize();

    //Create an output stream for resized EPS
    using (Stream outputEpsStream = new System.IO.FileStream(dataDir + "output_resize_mms.eps", System.IO.FileMode.Create, System.IO.FileAccess.Write))
    {
        //Save EPS to the output stream with new size assigned in percents
        doc.ResizeEps(outputEpsStream, new SizeF(200, 200), Units.Percents);
    }
}
