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

# 使用 Aspose.Imaging.Image.Load 是一种统一的方式来加载包括 WMF 在内的所有类型的图像。
with as_of(Image.load("test.wmf") as image:
	saveOptions = SvgOptions()
	# 文本将被转换为形状。
	saveOptions.text_as_shapes = True
	rasterizationOptions = WmfRasterizationOptions()
	# 绘图表面的背景颜色。
	rasterizationOptions.background_color = Color.white_smoke
	# 页面大小。
	rasterizationOptions.page_size = cast(SizeF, wmfImage.size)
	# 如果存在嵌入的 emf，则渲染 emf；否则渲染 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\\"
	
# 为目标加载的图像设置 10 兆字节的内存限制。
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)

The following example shows how to export all pages of CDR document to PDF.

from aspose.imaging import Image, TextRenderingHint, SmoothingMode
from aspose.imaging.imageoptions import PdfOptions, CdrRasterizationOptions, PositioningTypes
from os.path import join

dir_: str = "c:\\3570"
input_cdr_file_name: str = join(dir_, "tiger.cdr")
output_pdf_file_name: str = join(dir_, "tiger.cdr.pdf")
with Image.load(input_cdr_file_name) as image:
	pdf_options = PdfOptions()
	rasterization_options = CdrRasterizationOptions()
	rasterization_options.text_rendering_hint = TextRenderingHint.SINGLE_BIT_PER_PIXEL
	rasterization_options.smoothing_mode = SmoothingMode.NONE
	rasterization_options.positioning = PositioningTypes.DEFINED_BY_DOCUMENT
	pdf_options.vector_rasterization_options = rasterization_options
	image.save(output_pdf_file_name, pdf_options)
