使用wxPython + pymupdf消除渲染PDF的锯齿

import wx
import fitz  # PyMuPDF

class PDFFrame(wx.Frame):
    def __init__(self, parent, pdf_path):
        super().__init__(parent, title="PDF Viewer", size=(800, 600))
        self.pdf_path = pdf_path
        self.panel = wx.Panel(self)
        self.bmp = wx.Bitmap()
        self.render_pdf()

    def render_pdf(self):
        # 打开PDF文件
        doc = fitz.open(self.pdf_path)
        page = doc.load_page(0)  # 加载第一页

        # 设置DPI
        zoom = 2  # 放大倍数
        mat = fitz.Matrix(zoom, zoom)

        # 渲染PDF页面为图像
        pix = page.get_pixmap(matrix=mat, alpha=False)
        img = wx.Image(pix.width, pix.height, pix.samples)

        # 将pixmap转换为wx.Image
        for y in range(pix.height):
            for x in range(pix.width):
                img.SetRGB(x, y, pix.get_rgb(x, y))

        # 创建Bitmap并显示
        self.bmp = wx.Bitmap(img)
        self.panel.Refresh()

    def on_paint(self, event):
        dc = wx.BufferedPaintDC(self.panel)
        dc.DrawBitmap(self.bmp, 0, 0)

if __name__ == "__main__":
    app = wx.App(False)
    frame = PDFFrame(None, "path_to_your_pdf.pdf")
    frame.Show()
    app.MainLoop()
