Hi,
I have tested this with aspose-slides 22.10 and 22.12 versions. When parsing uploaded pptx file(example-slide.pptx) and export slide to images. Slide has a chart with table of data, but exported image have text box in wrong possition.
Example of result image slide-result.jpg​​
Capture.PNG (89.3 KB)

example-slide.zip (217.6 KB)

slide-result.jpg (185.3 KB)

Image created:

ISlide​ slide = ......;
slide.getImage​(renderingOptions​, new Dimension(IMAGE_WIDTH, height));

Can you take a look why this is happening and how we could fix that?

It seems you are experiencing an issue with the positioning of text boxes when exporting slides to images using Aspose.Slides. This can sometimes occur due to the way the text boxes and shapes are rendered during the export process.

To troubleshoot and potentially resolve this issue, consider the following steps:

  1. Check Text Box Properties: Ensure that the text boxes in your PPTX file are correctly defined. You can use the is_text_box property to verify that the shapes are indeed text boxes. This can help confirm that the shapes are being recognized correctly by the Aspose.Slides library.

  2. Adjust Rendering Options: When exporting the slide to an image, you might want to experiment with different rendering options. The renderingOptions parameter can be adjusted to see if it affects the output.

  3. Update Aspose.Slides Version: Since you mentioned testing with versions 22.10 and 22.12, consider checking if there are any newer versions available. Sometimes, issues are resolved in later releases, so updating to the latest version might help.

  4. Review the Export Code: Ensure that the code used for exporting the slide is correctly implemented. Here’s a basic example of how to export a slide to an image:

    from aspose.slides import Presentation
from aspose.slides.export import ImageOptions

presentation = Presentation("example-slide.pptx")
slide = presentation.slides[0]  # Access the first slide
image_options = ImageOptions()  # Set your image options here
slide.get_image(image_options, new Dimension(IMAGE_WIDTH, height))

  5. Test with Different Slides: If possible, try exporting other slides or presentations to see if the issue is specific to the example-slide.pptx file. This can help determine if the problem lies within the specific content of that slide.

If the issue persists after trying these suggestions, consider reaching out to the Aspose support team with detailed information about your findings, including the specific versions used and any error messages encountered.

Feel free to share any additional details or screenshots that might help in diagnosing the problem further.

I have tried all these options and results are the same.

@ANDREA.FARRIS,

Thanks for the Presentation file and screenshots.

After initial testing, I am able to reproduce the issue as you mentioned by using your Pesentation file and following sample code. I found wrong text box position rendered in the exported image.

Presentation pres = new Presentation("d:\\files\\example-slide.pptx");
Dimension size = new Dimension(960, 720);
        try {
            for (int index = 0; index < pres.getSlides().size(); index++)
            {
                ISlide slide = pres.getSlides().get_Item(index);
                IImage slideImage = slide.getImage(size);
                try {
                      slideImage.save("d:\\files\\image_java_1" + index + ".png");
                } finally {
                     if (slideImage != null) slideImage.dispose();
                }
            }
        } finally {
            if (pres != null) pres.dispose();
        }
