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

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.
center_drawing	bool	r/w	Gets or sets a value indicating whether center drawing.
draw_color	Color	r/w	Gets or sets a foreground color.
page_height	float	r/w	Gets or sets the page height. If the value is 0, the source image aspect ratio will be preserved.
page_size	SizeF	r/w	Gets or sets the page size. If one of SizeF dimensions is 0, the source image aspect ratio will be preserved.
page_width	float	r/w	Gets or sets the page width. If the value is 0, the source image aspect ratio will be preserved.
positioning	PositioningTypes	r/w	Gets or sets the positioning.
smoothing_mode	SmoothingMode	r/w	Gets or sets the smoothing mode.
text_rendering_hint	TextRenderingHint	r/w	Gets or sets the text rendering hint.

Methods

Name	Description
clone()	Creates a new object that is a shallow copy of the current instance.
copy_to(vector_rasterization_options)	Copies to.

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)
