Interface IImageExportStrategy

All Known Implementing Classes:

CustomImagesStrategy, ExportImagesAsBase64Strategy, ExportImagesToFileSystemStrategy, SkipImagesStrategy

public interface IImageExportStrategy

Defines a strategy for handling image export during document-to-Markdown conversion. Implement this interface to control where and how images extracted from the source document are stored.

The library ships with several built-in strategies:

• ExportImagesAsBase64Strategy — embeds images inline as Base64, the default.
• ExportImagesToFileSystemStrategy — writes images to a folder on disk.
• SkipImagesStrategy — omits images entirely.
• CustomImagesStrategy — delegates to a callback you supply.

Implement this interface directly when none of the built-in strategies meet your needs.

Example:

{@code
 public class CloudImageExportStrategy implements IImageExportStrategy {

Method Summary

Modifier and Type	Method and Description
String	getImagesFolder() Gets the folder path where exported images will be stored.
OutputStream	getImageStream(ImageExportContext context) Returns a writable stream for the image described by context.

Method Detail

getImagesFolder

String getImagesFolder()

Gets the folder path where exported images will be stored.

Returns:

a relative or absolute folder path. This value is used to construct image URIs in the Markdown output.

getImageStream

OutputStream getImageStream(ImageExportContext context)

Returns a writable stream for the image described by context. The library writes the image bytes to this stream during conversion.

Parameters:

context - The image export context containing the default image file name and other metadata. You may modify imageFileName before returning the stream to change the file name that appears in the Markdown output.

Returns:

a writable stream where the image data will be written, or null to use the default behavior
