A PDF page is defined in PDF coordinate system which uses the lower-left corner of the page as origin point (0, 0).
Usually, a PDF page object is retrieved from a PDF document by function FSPDFDoc::getPage:. For most case, a PDF page should be parsed first and then be used. Function FSPDFPage::isParsed can be used to judge whether the PDF page has been parsed or not. For a unparsed page, please use function FSPDFPage::startParse:pause:is_reparse: to parse it.
This class offers functions to get/set data of a PDF page, such as page width/height, page rotation, display matrix and so on. Also, this class offers functions to retrieve PDF annotations:
Class FSPDFPage is derived from class FSGraphicsObjects, so class PDFPage also offers functions to retrieve PDF graphics objects:
This class object can also be used to construct objects of other classes in order to access specified information in PDF page:

Markup annotations can be grouped. The group consists of a primary annotation and one or more subordinate annotations. Some entries in the primary annotation are treated as group attributes that should apply to the group as a whole; the corresponding entries in the subordinate annotations should be ignored. These entries are contents, last modification time, fill color/border color, title, pop-up annotation, creation time, subject, and open status. So user should respect the group property: when a property of an annotation in the group is changed, the other annotations in the same group should be changed too.
Operations that manipulate any annotation in a group, such as movement, cut, and copy, should be treated by viewer applications as acting on the entire group.

This array should contains at least 2 markup annotations, and all the markup annotations in this array should be different from others. All the markup annotations in this array should be in current page. Specially, if a markup annotation in this array is already in another group, that group will be set to the new group with the new header as well. |
[in] | header_index | The index that specifies a markup annotation in parameter annot_array to be the header of the group. Valid range: from 0 to (ammot_count -1). |
- (void) setBox: | (FSPDFPageBoxType) | box_type | |
box: | (FSRectF*) | box | |
Set page box.
[in] | box_type | Page box type. Please refer to values starting from FSPDFPageMediaBox and this should be one of these values. |
[in] | box | New box rectangle, in PDF coordinate system. |
- (void) setClipRect: | (FSRectF*) | clip_rect |
Set clip rectangle for all graphics objects on current PDF page.
After this function finishes successfully, please re-parse current page by function FSPDFPage::startParse:pause:is_reparse: with parameter is_reparse YES.
[in] | clip_rect | New clip rectangle, in PDF coordinate system. |
- (void) setSize: | (float) | width | |
height: | (float) | height | |
Set page width and height.
When changing page width/height, Foxit PDF SDK will always do as following:
First, choose "page rotation is 0" as the basis page status and choose the left-bottom corner of the page (with page rotation is 0) as the basis point. And then, always change the position of top page boundary and right page boundary (with page rotation is 0) to change page size.
[in] | width | New page width. It should be a positive value and the unit is 1/72 inch. |
[in] | height | New page height. It should be a positive value and the unit is 1/72 inch. |
- (void) setSizeWithType: | (FSPDFPageSize) | size |
Set page size type.
When changing page size, Foxit PDF SDK will always do as following:
First, choose "page rotation is 0" as the basis page status and choose the left-bottom corner of the page (with page rotation is 0) as the basis point. And then, always change the position of top page boundary and right page boundary (with page rotation is 0) to change page size.
[in] | size | Size type to specify the new size of current page. Please refer to values starting from FSPDFPageSizeLetter and this should be one of these values. |
- (void) setThumbnail: | (FSBitmap*) | thumbnail |
Set page thumbnail.
Thumbnail bitmap does not use alpha channel. So user is recommended to set a bitmap without alpha channel to be the new thumbnail. If a bitmap with alpha channel is set, the new thumbnail will use white background by default.
[in] | thumbnail | New page thumbnail. It should be a valid bitmap. |
- (FSProgressive *) startParse: | (unsigned int) | flags | |
pause: | (id<FSPauseCallback>) | pause | |
is_reparse: | (BOOL) | is_reparse | |
Start to parse current page.
It may take a long time to parsing a PDF page, so Foxit PDF SDK uses a progressive process to do this. All the resources of page content will be loaded after the PDF page is parsed.
[in] | flags | Parsing flags. Please refer to values starting from FSPDFPageParsePageNormal and this should be one or a combination of these values. |
[in] | pause | Pause callback object which decides if the parsing process needs to be paused. This can be nil which means not to pause during the parsing process. If this is not nil, it should be a valid pause object implemented by user. |
[in] | is_reparse | YES means to re-parse current page, while NO means not to re-parse current page. |
- (BOOL) transform: | (FSMatrix2D*) | matrix | |
need_transform_clip_path: | (BOOL) | need_transform_clip_path | |
Transform a PDF page, including annotations and form fields on the page.
[in] | matrix | Transform matrix. |
[in] | need_transform_clip_path | YES means to transform the page with clip rectangle, while NO means not. |
- (void) updateAnnotList |
Update the annotation list.
If any annotation is modified(added/removed...) by changing "Annots" dictionary item directly, please call this function to update the annotation list after the changing.
