用Python+PIL将多个jpg图像批量合并成一个pdf文件

from PIL import Imageimport os



def jpg2pdf(jpgFile):     global imglist

    path,fileName = jpgFile.rsplit('\\',1)    preName,postName = fileName.rsplit('.',1)



    img = Image.open(jpgFile)    imglist.append(img)    return img.save(path+"\\"+preName+'.pdf', "PDF", resolution=100.0, save_all=True)



def jpg2pdfByPath(pathName):    global imglist      imglist = []    imgfile = ''    files = os.listdir(pathName)    for f in files:        if f.lower().find(".jpg")>0 :

            jpg2pdf(pathName+'\\'+f)            imgfile = f         

    imgMerge = imglist.pop(0) #取出第一个图片示例

    imgMerge.save(pathName+r'\merge.pdf',"PDF", resolution=100.0, save_all=True, append_images=imglist)    print("all images processed!")



jpg2pdfByPath(r'F:\temp\pic')
