Converting Presentation to TIFF format using Aspose.Slides for Java

Aspose.Slides Product Family

Hello Aspose,

I have to convert *.ppt, *.pptx, *.odp files to the TIFF format with CCITTFAX3 compression, 1 bit per pixel. I tried this code:

import com.aspose.slides.ImagePixelFormat;
import com.aspose.slides.Presentation;

    public class SlidesTest {

        public static void main(String[] args) {
            Presentation presentation = new Presentation(SlidesTest.class.getResourceAsStream("off6626PptxAttachment.pptx"));

            com.aspose.slides.TiffOptions options = new com.aspose.slides.TiffOptions();
            options.setPixelFormat(ImagePixelFormat.Format1bppIndexed);
            // options.setCompressionType(TiffCompressionTypes.CCITT4);

            // Save the presentation to TIFF with specified image size
            presentation.save("off6626PptxAttachment.tiff", com.aspose.slides.SaveFormat.Tiff, options);
        }
    }

It appears to me, that setting the pixel format is ignored because the result is a TIFF with colour. Also, the line with options.setCompressionType(…) causes an exception when activated, complaining that CCITT3 (or 4) requires 1bpp.

Is this a bug or restriction in Aspose or am I doing something wrong?
