Java Requires Chilkat v11.2.0+

Multimodal Input: File Data

Demonstrates sending a request that includes both text and PDF file data for the AI to analyze.

Note: At the time of writing this example, xAI, Perplexity, and DeepSeek do not have the ability to accept non-image multimodal data or URLs.

        // Sample output:

        // This PDF file contains a famous quote from William Shakespeare's "Romeo and Juliet". The quote appears twice on the page:
        //
        // "These violent delights have violent ends
        // And in their triumph die, like fire and powder,
        // Which as they kiss consume. The sweetest honey
        // Is loathsome in his own deliciousness
        // And in the taste confounds the appetite.
        // Therefore love moderately; long love doth so;
        // Too swift arrives as tardy as too slow."
        //
        // The file also includes a portrait image of William Shakespeare. This particular quote is spoken by Friar Lawrence in the play, warning about the dangers of passionate,
        // immoderate love - suggesting that love that burns too intensely tends to burn out quickly, just as fire and gunpowder consume each other when they meet.
