Extract images from documents
GroupDocs.Parser allows to extract images from PDF, Emails, Ebooks, Microsoft Office: Word (DOC, DOCX), PowerPoint (PPT, PPTX), Excel (XLS, XLSX), LibreOffice formats and many others (see full list at supported document formats article).
GroupDocs.Parser’s allows to easily implement simple and complex image extraction cases at the same time (see more at advanced help section).
In this article you can see how to extract images from any supported format without additional settings.
Extract images from documents
To extract images from documents simply call GetImages method:
IEnumerable<PageImageArea> GetImages();
The methods return a collection of PageImageArea objects:
| Member | Description |
|---|---|
| Page | The page that contains the text area. |
| Rectangle | The rectangular area on the page that contains the text area. |
| FileType | The format of the image. |
| Rotation | The rotation angle of the image. |
| Stream GetImageStream() | Returns the image stream. |
| Stream GetImageStream(ImageOptions) | Returns the image stream in a different format. |
| void Save(String) | Saves the image to the file. |
| void Save(String, ImageOptions) | Saves the image to the file in a different format. |
Here are the steps to extract images from the whole document:
- Instantiate Parser object for the initial document;
- Call GetImages method and obtain collection of image objects;
- Check if collection isn’t null (images extraction is supported for the document);
- Iterate through the collection and get sizes, image types and image contents.
The following example shows how to extract all images from the whole document:
// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
// Extract images
IEnumerable<PageImageArea> images = parser.GetImages();
// Check if images extraction is supported
if (images == null)
{
Console.WriteLine("Images extraction isn't supported");
return;
}
// Iterate over images
foreach (PageImageArea image in images)
{
// Print a page index, rectangle and image type:
Console.WriteLine(string.Format("Page: {0}, R: {1}, Type: {2}", image.Page.Index, image.Rectangle, image.FileType));
}
}
