Python pdf转png

pdf转图片，WPS转换是收费的，免费的是有水印的，就写了这个代码。文件下载是打包好的.exe

不带GUI核心代码：

    for pg in range(total):

        rotate = int(0)
        trans = fitz.Matrix(zoom / 100.0, zoom / 100.0).prerotate(rotate)
        pm = page.get_pixmap(matrix=trans, alpha=False)
        if not os.path.exists(png_path):
            os.mkdir(png_path)
        save = os.path.join(png_path, '%s.png' %(pg+1))
        pm.save(save)
    doc.close()
if __name__ == "__main__":

    covert2pic(pdfPath, 200, imagePath)
