More user-friendly way to create image messages from local image files #58
Description
Creating an user image message from a URL is straight forward using UserMessage.buildImageMessage.
Creating an user image message from a local image file is much more tedious, here's some sample code:
public void postDiagramImage(String userMessageText, Path diagramImagePath) {
List<ChatMessage> messages = ...
UserMessage imageMessage = createImageMessage(userMessageText, diagramImagePath);
messages.add(imageMessage);
...
}
private UserMessage createImageMessage(String userMessageText, Path imagePath) {
ImageContent userMessageContent = new ImageContent(userMessageText);
String imagePathString = imagePath.toAbsolutePath().toString();
String extension = imagePathString.substring(imagePathString.lastIndexOf('.') + 1);
String imageUrl = "data:image/" + extension + ";base64," + encodeImage(imagePath);
ImageContent imageContent = new ImageContent(new ImageUrl(imageUrl));
UserMessage imageMessage = new UserMessage(List.of(userMessageContent, imageContent));
return imageMessage;
}
private String encodeImage(Path imagePath) {
byte[] fileContent;
try {
fileContent = Files.readAllBytes(imagePath);
return Base64.getEncoder().encodeToString(fileContent);
} catch (IOException e){
throw new RuntimeException(e);
}
}It would be great if code like this could be encapsulated, and provided to the user in a friendly manner.
