delphi怎么读pdf?

Question

使用adobe的AcroPDFLib_TLB组件可以整体很好的显示出pdf,
但我想根据光标位置把pdf里的文章一句一句的读到程序里,即得到句子的字符串,有什么办法吗?

Answer 1

AcroPDFLib_TLB应该有这个接口吧

Answer 2

好像都没有能返回字符串的接口

    procedure Set_src(const pVal: WideString); safecall;

    procedure setShowToolbar(On_: WordBool); safecall;
    procedure gotoFirstPage; safecall;

    property messageHandler: OleVariant read Get_messageHandler write Set_messageHandler;

Answer 3

AcroPDF1.setCurrentPage(PDF文件页码)，这样可以转到相应的页，你说的得到字符，没有试过

Answer 4

呵呵,我们说的是同一个控件吧? 
C:\Program Files\Common Files\Adobe\Acrobat\ActiveX\AcroPDF.dll
里面基本没有带返回值的方法呀

Answer 5

试试这个，呵呵
