从第一页删除标题和页脚

Question

 class MyDocTemplate(BaseDocTemplate):
        def __init__(self, filename, **kw):
            self.allowSplitting = 0
            apply(BaseDocTemplate.__init__, (self, filename), kw)
            template = PageTemplate('normal', [Frame(1.0*cm, 1*cm, 19*cm, 27*cm, id='F1')])
            self.addPageTemplates(template)
        def afterFlowable(self, flowable):
            if flowable.__class__.__name__ == 'Paragraph':
            text = flowable.getPlainText()
            style = flowable.style.name
            if style == 'Heading1':
                level = 0
            elif style == 'Heading2':
                level = 1
            else:
                return
            E = [level, text, self.page]
    #if we have a bookmark name append that to our notify data
            bn = getattr(flowable,'_bookmarkName',None)
            if bn is not None:
                E.append(bn)
            self.notify('TOCEntry', tuple(E))
 class FooterCanvas(canvas.Canvas):
     def __init__(self, *args, **kwargs):
         canvas.Canvas.__init__(self, *args, **kwargs)
         self.pages = []
     def showPage(self):
         self.pages.append(dict(self.__dict__))
         self._startPage()
     def save(self):
         page_count = len(self.pages)
         for page in self.pages:
             self.__dict__.update(page)
             self.draw_canvas(page_count)
             canvas.Canvas.showPage(self)
         canvas.Canvas.save(self)
     def draw_canvas(self, page_count):
         page = "Page %s" % (self._pageNumber)
         self.saveState()
         self.setFont('Times-Roman', 10)
         self.line(40,23,560,23)
         self.drawString(280, 25, page)
         self.line(40, 810, 560, 810)
         self.drawString(40,813,"abc")
         self.restoreState()

您可以看到，这将创建TOC，以及FooterCanvas类和FooterCanvas类的标题和页脚正在应用于所有页面，但我不希望它将其应用于我的PDF的第一页。那么我该如何实现？

Answer 1

看起来只有一个pagetemplate。当我想要类似的控件时，我会创建两个单独的pagetemplate，例如下面。

frontpage = PageTemplate(id='FrontPage', onPage=footer, frames=[]) 
backpage = PageTemplate(id='BackPage', onPage=header, frames=[])
MyDocTemplate.addPageTemplates(frontpage) MyDocTemplate.addPageTemplates(backpage)

Answer 2

我在其他答案的帮助下找到了另一种方法。所以在这里。

Frame1=Frame(x1,y1,width,height,id='F1')
Frame2=Frame(x1,y1,width,height,id='F2')
def FooterCanvas(canvas,doc):
    page = "Page %s" % (canvas._pageNumber)
    canvas.saveState()
    canvas.setFont('Times-Roman', 10)
    canvas.drawString(280, 15, page)
    canvas.restoreState()
class MyDocTemplate(BaseDocTemplate):
    def __init__(self, filename, **kw):
        self.allowSplitting = 0
        apply(BaseDocTemplate.__init__, (self, filename), kw)
        self.addPageTemplates([PageTemplate(id='firstPage',frames=Frame1),PageTemplate(id='allpages',frames=Frame2,onPage=FooterCanvas)
            ])
    def afterFlowable(self, flowable):
        if flowable.__class__.__name__ == 'Paragraph':
            text = flowable.getPlainText()
            style = flowable.style.name
            if style == 'Heading1':
                self.notify('TOCEntry', (0, text, self.page))
            if style == 'Heading2':
                self.notify('TOCEntry', (1, text, self.page))
Story=[]
write your styles here and write your TOC styles. create TOC instance and add levels for TOC(levels are optional).
Story.append(NextPageTemplate('firstpage'))
First page with some paragraph or graphics.
Story.append(NextPageTemplate('allpages'))
Story.append(PageBreak())
Rest of the pages with some paragraph or graphics.
doc=MyDocTemplate("abc.pdf")
doc.multiBuild(Story)
