从 PDF 导入 3D 场景和内容

Aspose.3D API 的 Scene 类表示 3D 场景。开发人员可以从 PDF 文件中提取 3D 场景和内容。

从受密码保护的 PDF 打开场景

Scene 类的 open 方法允许从输入 PDF 文件加载 3D 场景。开发人员还可以使用 PdfLoadOptions 类为受保护的pdf应用密码，如下面的代码示例所示:

from aspose.threed import Scene
from aspose.threed.formats import PdfLoadOptions

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  Create a new scene
scene = Scene()
options = PdfLoadOptions()
options.password = "password".encode("utf-8")
#  Use loading options and apply password
opt = options
#  Open scene
scene.open("data-dir"  + "House_Design.pdf", opt)

从 PDF 中提取所有原始 3D 内容

PdfFormat 类的 extract 方法允许从 PDF 文件中提取 3D 内容。开发人员可以遍历内容，并将它们保存到单独的文件中，如下代码示例所示:

from aspose.threed import FileFormat

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  The path to the documents directory.
password = None
#  Extract 3D contents
contents = FileFormat.PDF.extract("data-dir"  + "House_Design.pdf", password)
i = 1
#  Iterate through the contents and in separate 3D files
for content in contents:
    fileName = "3d-"  + str(i)
    i = i + 1
    with open(fileName, "wb") as f:
        f.write(content)

提取所有 3D 场景并将其保存为支持的 3D 格式

PdfFormat 类的 extract_scene 方法允许从 PDF 文件中提取 3D 场景。开发人员可以遍历场景，并将它们保存为支持的 3D 文件格式，如下面的代码示例所示:

from aspose.threed import FileFormat

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
password = None
scenes = FileFormat.PDF.extract_scene("data-dir"  + "House_Design.pdf", password)
i = 1
#  Iterate through the scenes and save in 3D files
for scene in scenes:
    fileName = "3d-"  + str(i) + ".fbx"
    i = i + 1
    scene.save("out"  + fileName, FileFormat.FBX7400ASCII)

所有受支持的 3D 文件格式都列在 产品概述 页中。
