Each page in a PDF document is identified by an integer page index that expresses the page's relative position within the document. In addition, a document may optionally define page labels (PDF 1.3) to identify each page visually on the screen or in print. Page label titles and page indices need not coincide: the indexes are fixed, running consecutively through the document starting from 0 for the first page, but the label titles can be specified in any way that is appropriate for the particular document. For example, if the document begins with 12 pages of front matter numbered in roman numerals and the remainder of the document is numbered in arabic, the first page would have a page index of 0 and a page label title of i, the twelfth page would have index 11 and label title xii, and the thirteenth page would have index 12 and label title 1.
For purposes of page labeling, a document can be divided into labeling ranges, each of which is a series of consecutive pages using the same numbering system. Pages within a range are numbered sequentially in ascending order. A page's label (as numbering format), consists of a numeric portion based on its position within its labeling range, optionally preceded by a label prefix denoting the range itself. For example, the pages in an appendix might be labeled with decimal numeric portions prefixed with the string A-; the resulting page labels would be A-1, A-2, and so on. Please refer to Section 8.3.1 "Page Labels" in <PDF Reference 1.7> for more details.
This class can be used to get page label full title directly, get information of a page label (as numbering format), set or add a new page label, and so on.
def FoxitPDFSDKPython3.PageLabels.PageLabels | ( | document | ) |
Constructor, from a PDF document object.
Constructor, with another page labels object.
If there exists page labeling range information in the specified PDF document, this function is just to construct a page labels object to be associated with these information. If there is no such information in the specified PDF document, the constructed page labels object can be used to set page labeling range information to PDF document.
[in] | document | A valid PDF document object. |
[in] | other | Another page labels object. |
def FoxitPDFSDKPython3.PageLabels.GetNumberTree | ( | ) |
Get the page labels number tree.
def FoxitPDFSDKPython3.PageLabels.GetPageLabelPrefix | ( | page_index | ) |
Get the label prefix string in the page label (as numbering format) of a specified page index.
This function is only useful when input page index has a page label – that means the page index is the starting page index of a page labeling range. Function FoxitPDFSDKPython3.PageLabels.HasPageLabel can be used to check if the page index has a page label. If input page index does not have page label, this function will return empty string.
[in] | page_index | The page index which is the starting page index of a page labeling range. Valid range: from 0 to (count-1). count is the page count of related PDF document, and can be retrieved by function FoxitPDFSDKPython3.PDFDoc.GetPageCount . |
def FoxitPDFSDKPython3.PageLabels.GetPageLabelStart | ( | page_index | ) |
Get the value of the numeric portion for the first page label in the page label (as numbering format) of a specified page index.
Subsequent pages are numbered sequentially from this value until the next page labeling range appears. This value must be greater than or equal to 1.
This function is only useful when input page index has a page label – that means the page index is the starting page index of a page labeling range. Function FoxitPDFSDKPython3.PageLabels.HasPageLabel can be used to check if the page index has a page label. If input page index does not have page label, this function will return -1.
[in] | page_index | The page index which is the starting page index of a page labeling range. Valid range: from 0 to (count-1). count is the page count of related PDF document, and can be retrieved by function FoxitPDFSDKPython3.PDFDoc.GetPageCount . |
def FoxitPDFSDKPython3.PageLabels.GetPageLabelStyle | ( | page_index | ) |
Get the numbering style to be used for the numeric portion in the page label (as numbering format) of a specified page index.
This function is only useful when input page index has a page label – that means the page index is the starting page index of a page labeling range. Function FoxitPDFSDKPython3.PageLabels.HasPageLabel can be used to check if the page index has a page label. If input page index does not have page label, this function will return -1.
[in] | page_index | The page index which is the starting page index of a page labeling range. Valid range: from 0 to (count-1). count is the page count of related PDF document, and can be retrieved by function FoxitPDFSDKPython3.PDFDoc.GetPageCount . |
def FoxitPDFSDKPython3.PageLabels.GetPageLabelTitle | ( | page_index | ) |
Get the full page label title for a page specified by page index.
This function can help to get the full page label title of a specified page index directly, and user does not need to take care about which page labeling range this page belongs to.
Only when related PDF document does not have any page labeling range information, this function would return empty string for each valid page index.
[in] | page_index | A page index. Valid range: from 0 to (count-1). count is the page count of related PDF document, and can be retrieved by function FoxitPDFSDKPython3.PDFDoc.GetPageCount . |
def FoxitPDFSDKPython3.PageLabels.HasPageLabel | ( | page_index | ) |
Check if there is a page label (as numbering format) defined with specified page index.
For each page labeling range, the page label (as numbering format) is defined with its starting page index.
[in] | page_index | A page index. Valid range: from 0 to (count-1). count is the page count of related PDF document, and can be retrieved by function FoxitPDFSDKPython3.PDFDoc.GetPageCount . |
def FoxitPDFSDKPython3.PageLabels.IsEmpty | ( | ) |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
def FoxitPDFSDKPython3.PageLabels.RemoveAll | ( | ) |
Remove all page labels.
def FoxitPDFSDKPython3.PageLabels.RemovePageLabel | ( | page_index | ) |
Remove a page label (as numbering format) defined with a specified page index.
After the specified page label is removed, the related labeling range will be merged to the previous page labeling range sequence.
As required in Section 8.3.1 "Page Labels" in <PDF reference 1.7>, a page label defined with page index 0 is required. So user is recommended not to remove the page label of page index 0 singly.
[in] | page_index | The page index which is the starting page index of a page labeling range. Valid range: from 0 to (count-1). count is the page count of related PDF document, and can be retrieved by function FoxitPDFSDKPython3.PDFDoc.GetPageCount . Not recommend to remove the page label defined with page index 0 singly as required in Section 8.3.1 "Page Labels" in <PDF reference 1.7>, |
def FoxitPDFSDKPython3.PageLabels.SetPageLabel | ( | page_index, | |
label_style, | |||
first_label_number, | |||
prefix_string | |||
) |
Set a page label (as numbering format) defined with a page index which is the starting page index of the range.
If no any page labeling range in the related PDF document, this function will set input page index as the starting page of a new page labeling range and use input values as page label (as numbering format) for this new range. Pages following the specified page will be in the same labeling range, until the next page labeling range appears. Specially, in this case, if input page index is not 0, this function will also add a new page label for index 0, with no label style, no prefix, first label number = 1, by default – this is required in Section 8.3.1 "Page Labels" in <PDF reference 1.7>.
If these is no page label for input page index, this function will set input page index as the starting page of a new page labeling range and use input values as page label (as numbering format) for this new range. Pages following the specified page will be in the same labeling range, until the next page labeling range appears.
If there exists a page label for input page index, this function will replace the old page label (as numbering format) with input values.
[in] | page_index | The page index which is the starting page index of a page labeling range. Valid range: from 0 to (count-1). count is the page count of related PDF document, and can be retrieved by function FoxitPDFSDKPython3.PDFDoc.GetPageCount . |
[in] | label_style | The numbering style to be used for the numeric portion in the page labeling range. Please refer to values starting from FoxitPDFSDKPython3.PageLabels.e_None and this should be one of these values. |
[in] | first_label_number | The value of the numeric portion for the first page label in the page labeling range. It should be greater than or equal to 1. If the input value is invalid, Foxit PDF SDK will use 1 by default. |
[in] | prefix_string | The label prefix string for page labels in the labeling range. This can be an empty string which means not use prefix string. Default value : an empty string. |
