Convert Word files to image formats in C# and VB.NET
With GemBox.Document you can easily convert Word files to images using just C# or VB.NET code. You can save your document to any type of Saving a single page of a Word document as an image is useful for generating the document's preview or thumbnail. To create a single PNG or JPEG file from a Word file, you need to save the document with The following example shows how you can convert a Word page to a PNG image of a specified size. If a document doesn't specify page color then image formats that support transparency, like PNG, will have a transparent background and image formats that don't support transparency, like JPEG, will have a white background. Or you can specify what image background color should be used by setting the document's page color with the section's You can also save multiple pages from a Word document as a single multi-frame image. For this, you need to use an image format that supports multiple frames, like TIFF or GIF, and you need to specify the The following example shows how you can convert all Word pages to a multi-page TIFF image. You can also save each page from a Word document as a separate PNG or JPEG image. We recommend saving each ImageSaveFormat like PNG, JPEG, BMP, WMP, GIF, or TIFF.Convert a Word file to a single image
