从第1页删除页眉和页脚

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()

正如您所看到的，这将创建TOC以及FooterCanvas类的页眉和页脚，FooterCanvas类将应用于所有页面，但我不希望它应用于我的pdf的第一页。那我该怎么做呢？

Answer 1

看起来你只有一个PageTemplate。当我想要类似的控件时，我创建了两个单独的PageTemplates，如下所示。

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

MyDocTemplate.addPageTemplates(frontpage) MyDocTemplate.addPageTemplates(backpage)

Answer 2

在其他答案的帮助下，我找到了另一种方法。所以这就是。

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)
