添加线对象
Aspose.PDF for Python via .NET 允许您添加 线 形状到 PDF 页面，使用 Graph 类。您可以控制线的颜色、虚线模式和位置。
请按照以下步骤：
import aspose.pdf as ap
import aspose.pdf.drawing as drawing
def add_line(outfile: str):
document = ap.Document()
page = document.pages.add()
graph = drawing.Graph(100, 400)
page.paragraphs.add(graph)
line = drawing.Line([100, 100, 200, 100])
line.graph_info.dash_array = [0, 1, 0]
line.graph_info.dash_phase = 1
graph.shapes.add(line)
document.save(outfile)
如何在 PDF 文档中添加点划线
import aspose.pdf as ap
import aspose.pdf.drawing as drawing
def add_dotted_dashed_line(outfile: str):
document = ap.Document()
page = document.pages.add()
graph = drawing.Graph(100, 400)
page.paragraphs.add(graph)
line = drawing.Line([100, 100, 200, 100])
line.graph_info.color = ap.Color.red
line.graph_info.dash_array = [0, 1, 0]
line.graph_info.dash_phase = 1
graph.shapes.add(line)
document.save(outfile)
添加点划线后的结果：
在页面上绘制线条
您也可以在页面上绘制线条以形成十字交叉。
import aspose.pdf as ap
import aspose.pdf.drawing as drawing
def draw_line_across_page(outfile: str):
document = ap.Document()
page = document.pages.add()
page.page_info.margin.left = 0
page.page_info.margin.right = 0
page.page_info.margin.bottom = 0
page.page_info.margin.top = 0
graph = drawing.Graph(page.page_info.width, page.page_info.height)
line = drawing.Line([page.rect.llx, 0, page.page_info.width, page.rect.ury])
graph.shapes.add(line)
line2 = drawing.Line([0, page.rect.ury, page.page_info.width, page.rect.llx])
graph.shapes.add(line2)
page.paragraphs.add(graph)
document.save(outfile)
