示例1: renderTo
# 需要導入模塊: from qwt.qt.QtCore import QRectF [as 別名]
# 或者: from qwt.qt.QtCore.QRectF import setRect [as 別名]

"""
Render a plot to a file
Supported formats are:
- pdf: Portable Document Format PDF
- ps: Postcript
- svg: Scalable Vector Graphics SVG
- all image formats supported by Qt, see QImageWriter.supportedImageFormats()
Scalable vector graphic formats like PDF or SVG are superior to
raster graphics formats.
:param qwt.plot.QwtPlot plot: Plot widget
:param str fileName: Path of the file, where the document will be stored
:param str format: Format for the document
:param QSizeF sizeMM: Size for the document in millimeters.
:param int resolution: Resolution in dots per Inch (dpi)
