The latest Aspose Slides Java 19.12 does not show fill patterns in rotated shapes. I only know that it worked with Aspose Slides 15.11 and I don’t know when it stopped working.
Reproducable like this:
- Add a shape of type
Triangleto a slide. - Define fill pattern: vertical
- Rotate triangle by 90 degrees.
- Generate thumbnail.
Expected result: Triangle should be filled with the vertical lines pattern as in the PPTX file (pattern not rotated).
Actual result: Triangle is filled with the foreColor only.
Here my sample code that produces this behavior:
