Public API Changes
PDF 1.7 and PDF 1.6 export support added
We implemented support for PDF export to formats 1.6 and 1.7:
- PdfCompliance.PDF16
- PdfCompliance.PDF17
This Python code demonstrates an export to PDF 1.7 operation:
import aspose.slides as slides
with slides.Presentation("pres.pptx") as presentation:
options = slides.export.PdfOptions()
options.compliance = slides.export.PdfCompliance.PDF17
presentation.save("pres.pdf", slides.export.SaveFormat.PDF, options)
PDF A2a, A2b, A2u, A3a and A3b compliance levels export support added
We implemented support for PDF export operations with A2a, A2b, A2u, A3a and A3b compliance levels:
- PdfCompliance.PDF_A2A
- PdfCompliance.PDF_A2B
- PdfCompliance.PDF_A2U
- PdfCompliance.PDF_A3A
- PdfCompliance.PDF_A3B
This Python code demonstrates an operation where a PDF is saved based on the PdfCompliance.PDF_A2A compliance level:
import aspose.slides as slides
with slides.Presentation("pres.pptx") as presentation:
options = slides.export.PdfOptions()
options.compliance = slides.export.PdfCompliance.PDF_A2A
presentation.save("pres.pdf", slides.export.SaveFormat.PDF, options)
Hyperlink sound management support added
Hyperlink.sound, a new property, has been added to the Hyperlink class to represent the played sound of an hyperlink.
import aspose.slides as slides
with slides.Presentation("pres.pptx") as presentation:
slide = presentation.slides[0]
# Gets the first shape hyperlink
link = slide.shapes[0].hyperlink_click
if link.Sound is not None:
# Extracts the hyperlink sound in byte array
audioData = link.sound.binary_data
OLE object frame relative path to a linked file support added
We implemented a new ability that allows you to access and change the relative file path data for OleObjectFrame using the new OleObjectFrame.link_path_relative property.
import aspose.slides as slides
with slides.Presentation("pres.pptx") as presentation:
oleFrame = presentation.slides[0].shapes[0]
if type(oleFrame) is slides.OleObjectFrame and oleFrame is not None:
print("The relative path: " + oleFrame.link_path_relative)
StopPreviousSound property added for animation effects
The Effect.stop_previous_sound property of the Effect class specifies whether the animation effect stops the previous sound.
import aspose.slides as slides
with slides.Presentation("demo.pptx") as presentation:
# Gets the first effect of the first slide.
firstSlideEffect = presentation.slides[0].timeline.main_sequence[0]
# Gets the first effect of the second slide.
secondSlideEffect = presentation.slides[1].timeline.main_sequence[0]
if firstSlideEffect.sound is not None:
# Changes the second effect Enhancements/Sound to "Stop Previous Sound"
secondSlideEffect.stop_previous_sound = True
Get base placeholder support added
The Shape.get_base_placeholder method has been added. It returns a basic placeholder shape (shape from the layout and/or master slide that the current shape is inherited from).
This Python code shows you how to get all (master/layout/slide) animated effects of a placeholder shape:
import aspose.slides as slides
with slides.Presentation("pres.pptx") as pres:
slide = pres.slides[0]
shape = slide.shapes[0]
shapeEffects = slide.layout_slide.timeline.main_sequence.get_effects_by_shape(shape)
layoutShape = shape.get_base_placeholder()
layoutShapeEffects = slide.layout_slide.timeline.main_sequence.get_effects_by_shape(layoutShape)
masterShape = layoutShape.get_base_placeholder()
masterShapeEffects = slide.layout_slide.master_slide.timeline.main_sequence.get_effects_by_shape(masterShape)
