VectorRasterizationOptions Class

Summary: The vector rasterization options.
Please note that VectorRasterizationOptions will no longer derive from ImageOptionsBase
since Aspose.Imaging 24.12 version.

Module: aspose.imaging.imageoptions

Full Name: aspose.imaging.imageoptions.VectorRasterizationOptions

Inheritance: IHasXmpData, IHasMetadata, ImageOptionsBase

Constructors

Name	Description
VectorRasterizationOptions()	Initializes a new instance of the VectorRasterizationOptions class

Properties

Name	Type	Access	Description
background_color	Color	r/w	Gets or sets a background color.
border_x	float	r/w	Gets or sets the border X.
border_y	float	r/w	Gets or sets the border Y.
buffer_size_hint	int	r/w	Gets or sets the buffer size hint which is defined max allowed size for all internal buffers.
center_drawing	bool	r/w	Gets or sets a value indicating whether center drawing.
disposed	bool	r	Gets a value indicating whether this instance is disposed.
draw_color	Color	r/w	Gets or sets a foreground color.
full_frame	bool	r/w	Gets or sets a value indicating whether [full frame].
keep_metadata	bool	r/w	Gets a value whether to keep original image metadata on export.
multi_page_options	MultiPageOptions	r/w	The multipage options
page_height	float	r/w	Gets or sets the page height. If the value is 0, the source image aspect ratio will be preserved.

positioning	PositioningTypes	r/w	Gets or sets the positioning.
resolution_settings	ResolutionSetting	r/w	Gets or sets the resolution settings.
smoothing_mode	SmoothingMode	r/w	Gets or sets the smoothing mode.
source	Source	r/w	Gets or sets the source to create image in.
text_rendering_hint	TextRenderingHint	r/w	Gets or sets the text rendering hint.
vector_rasterization_options	VectorRasterizationOptions	r/w	Gets or sets the vector rasterization options.
xmp_data	XmpPacketWrapper	r/w	Gets or sets the XMP metadata container.

Examples

This example shows how to load a WMF image from a file and convert it to SVG using WmfRasterizationOptions.


from aspose.pycore import as_of, cast
from aspose.imaging import Image, Color, SizeF
from aspose.imaging.fileformats.wmf import WmfImage, WmfRenderMode
from aspose.imaging.imageoptions import SvgOptions, WmfRasterizationOptions

# Using Aspose.Imaging.Image.Load is a unified way to load all types of images including WMF.
with as_of(Image.load("test.wmf") as image:
	saveOptions = SvgOptions()
	# Text will be converted to shapes.
	saveOptions.text_as_shapes = True
	rasterizationOptions = WmfRasterizationOptions()
	# The background color of the drawing surface.
	rasterizationOptions.background_color = Color.white_smoke
	# The page size.
	rasterizationOptions.page_size = cast(SizeF, wmfImage.size)
	# If embedded emf exists, then render emf; otherwise render wmf.
	rasterizationOptions.render_mode = WmfRenderMode.AUTO
	saveOptions.vector_rasterization_options = rasterizationOptions
	wmfImage.save("test.output.svg", saveOptions)

The following example shows how to set a memory limit when loading a CMX image. The memory limit is the maximum allowed size (in megabytes) for all internal buffers.

from aspose.imaging import Image, TextRenderingHint, SmoothingMode, PositioningTypes, LoadOptions
from aspose.imaging.imageoptions import PngOptions, CmxRasterizationOptions
import os

directory = "c:\\aspose.imaging\\issues\\net\\3419\\"
	
# Setting a memory limit of 10 megabytes for a target loaded image.
load_options = LoadOptions()
load_options.buffer_size_hint = 10
with Image.load(os.path.join(directory, "example.cmx"), load_options) as image:
	png_options = PngOptions()
	cmx_spec = CmxRasterizationOptions()
	cmx_spec.text_renderingHint = TextRenderingHint.SINGLE_BIT_PER_PIXEL
	cmx_spec.smoothing_mode = SmoothingMode.ANTI_ALIAS
	cmx_spec.positioning = PositioningTypes.DEFINED_BY_DOCUMENT
	png_options.vector_rasterization_options = cmx_spec
	image.save(os.path.join(directory, "output.png"), png_options)
