The “Image loading failed” exception you are encountering when converting HEIC to PDF using Aspose.Imaging may be due to an unsupported HEIC file format or a corrupted file. Here are a few steps you can take to troubleshoot and resolve the issue:

  1. Check File Integrity: Ensure that the HEIC file is not corrupted. Try opening it with a different application to verify its integrity.

  2. Update Aspose.Imaging: Make sure you are using the latest version of Aspose.Imaging, as updates may include fixes for known issues with file formats.

  3. Convert to Supported Format: If the HEIC file continues to cause issues, consider converting it to a more common format (like JPEG or PNG) using a different tool before processing it with Aspose.Imaging.

  4. Sample Code: Here’s a basic example of how to load a HEIC file and save it as a PDF:

    using Aspose.Imaging;
using Aspose.Imaging.ImageOptions;

// Load the HEIC file
using (Image image = Image.Load("path/to/your/file.heic"))
{
    // Save as PDF
    image.Save("output.pdf", new PdfOptions());
}

If the problem persists after trying these steps, please provide additional details about the HEIC file or any error messages you receive for further assistance.

I’m using Aspose.Imaging 25.10 and that example code is exactly what I’m using. Can it be confirmed that this heic is not supported? I’m using Aspose so that I do not have to use another tool to convert to jpeg. Thanks!
