Dear Jedi,

Thanks for considering Aspose.Slides for JAVA

Yes, it is possible to take images of the slides using Aspose.Slides JAVA. Here is a complete code that takes a source presentation name and output the images of all slides in an output directory.

Just change the input/output directory name and source presentation name and run the code.

For general help, see Programmer’s Guide here.

Aspose Documentation

CODE

public static void getThumbnails() throws Exception {
    //Input and output directory
    String strPath = "D:\\downloads\\test3oct\\";

    //Source presentation name
    String strFile = "Jensen_v1.3-Test.ppt";

    //Create a source presentation object
    Presentation srcPres = new Presentation(new FileInputStream(new File(strPath + strFile)));

    //Get the collection(array) of slides
    Slides slds = srcPres.getSlides();

    //Get the count of normal slides (excluding master slides)
    int sldsCnt = slds.getLastSlidePosition();

    //Iterate all normal slides
    for (int i = 1; i <= sldsCnt; i++) {

        //Get ith slide
        Slide sld = srcPres.getSlideByPosition(i);

        //Get the thumbnail image, 1.0f, 1.0f is the scaling factor
        BufferedImage img = sld.getThumbnail(1.0f, 1.0f);

        //Create a file for the image
        File imgFile = new File(strPath + "slide" + i + ".jpg");

        //Write the image into the file
        ImageIO.write(img, "JPEG", imgFile);
    }
}

Thanks for your response, I’ll give that a go, my ultimate aim is to convert the Java code into ColdFusion, is there any example anywhere of using the above code in ColdFusion?
