Public API Changes

Support for the Tile properties of the PictureFillFormat

The following properties have been added to the IPictureFillFormat interface and PictureFillFormat class:

tile_offset_x property returns or sets the horizontal offset of the texture from the shape’s origin in points.
tile_offset_y property returns or sets the vertical offset of the texture from the shape’s origin in points.
tile_scale_x property returns or sets the horizontal scale for the texture fill as a percentage.
tile_scale_y property returns or sets the vertical scale for the texture fill as a percentage.
tile_alignment property returns or sets how the texture is aligned within the shape.
tile_flip property flips the texture tile around its horizontal, vertical or both axis.

The following code sample shows how to add the new Rectangle shape with a tiled picture fill and change the Tile properties:

import aspose.slides as slides

with slides.Presentation() as pres:
    first_slide = pres.slides[0]

    new_image = slides.Images.from_file("image.png")
    pp_image = pres.images.add_image(new_image)

    # Adds the new Rectangle shape
    new_shape = first_slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 0, 0, 350, 350)

    # Sets the fill type of the new shape to Picture
    new_shape.fill_format.fill_type = slides.FillType.PICTURE

    # Sets the shape's fill image
    picture_fill_format = new_shape.fill_format.picture_fill_format
    picture_fill_format.picture.image = pp_image

    # Sets the picture fill mode to Tile and changes the properties
    picture_fill_format.picture_fill_mode = slides.PictureFillMode.Tile
    picture_fill_format.tile_offset_x = -275
    picture_fill_format.tile_offset_y = -247
    picture_fill_format.tile_scale_x = 25
    picture_fill_format.tile_scale_y = 15
    picture_fill_format.tile_alignment = slides.RectangleAlignment.BOTTOM_RIGHT
    picture_fill_format.tile_flip = slides.TileFlip.FLIP_BOTH

    pres.save("Tile.pptx", slides.export.SaveFormat.PPTX)

The next code sample demonstrates how to set the background fill type to the tiled picture fill and change the Tile properties:

import aspose.slides as slides

with slides.Presentation() as pres:
    first_slide = pres.slides[0]

    new_image = slides.Images.from_file("image.png")
    pp_image = pres.images.add_image(new_image)

    # Gets the background of the first slide
    background = first_slide.background

    # Sets the type of the background to OwnBackground
    background.type = slides.BackgroundType.OWN_BACKGROUND

    # Sets the fill type of the background to Picture
    new_shape.fill_format.fill_type = slides.FillType.PICTURE

    # Sets the shape's fill image
    picture_fill_format = new_shape.fill_format.picture_fill_format
    picture_fill_format.picture.image = pp_image

    # Sets the picture fill mode to Tile and changes the properties
    picture_fill_format.picture_fill_mode = slides.PictureFillMode.Tile
    picture_fill_format.tile_offset_x = 15
    picture_fill_format.tile_offset_y = 15
    picture_fill_format.tile_scale_x = 46
    picture_fill_format.tile_scale_y = 87
    picture_fill_format.tile_alignment = slides.RectangleAlignment.CENTER
    picture_fill_format.tile_flip = slides.TileFlip.FLIP_Y

    pres.save("BackgroundTile.pptx", slides.export.SaveFormat.PPTX)

IFontsManager.get_font_bytes() and IFontsManager.get_font_embedding_level() methods have been added

A method get_font_bytes has been added to the IFontsManager interface and the FontsManager class. This method allows retrieving byte data of fonts from a presentation.

The following example shows how to retrieve binary font data from a presentation:

import aspose.slides as slides
import aspose.pydrawing as drawing

with slides.Presentation("Presentation.pptx") as pres:
    # Retrieve all fonts used in the presentation
	fonts = pres.fonts_manager.get_fonts()

    # Get the byte array representing the regular style of the first font in the presentation
	font_bytes = pres.fonts_manager.get_font_bytes(fonts[0], drawing.FontStyle.REGULAR)

A method get_font_embedding_level has been added to the IFontsManager interface and the FontsManager class. This method allows you to get the embedding level of the font.

The following example shows how to get the embedding level for a font:

import aspose.slides as slides
import aspose.pydrawing as drawing

with slides.Presentation("Presentation.pptx") as pres:
    # Retrieve all fonts used in the presentation
	fonts = pres.fonts_manager.get_fonts()

    # Get the byte array representing the regular style of the first font in the presentation
	font_bytes = pres.fonts_manager.get_font_bytes(fonts[0], drawing.FontStyle.REGULAR)

    # Determine the embedding level of the font
    embedding_level = pres.fonts_manager.get_font_embedding_level(font_bytes, fonts[0].font_name)

The font embedding level is described by enumeration EmbeddingLevel and can take the following values:

INSTALLABLE
RESTRICTED
PREVIEW_PRINT
EDITABLE
NO_SUBSETTING
BITMAP_ONLY
