Some test text!
A stamp in a PDF document is analogous to applying a rubber stamp on a paper document.
PDFTron SDK benefits include:
To stamp an image to a page in a PDF document.
PTPDFDoc *doc = [[PTPDFDoc alloc] initWithFilepath: filename]; PTStamper *s = [[PTStamper alloc] initWithSize_type: e_ptrelative_scale a: 0.05 b: 0.05]; PTImage *img = [PTImage Create: [doc GetSDFDoc] filename: imagename]; [s SetSize: e_ptrelative_scale a: 0.5 b: 0.5]; //set position of the image to the center, left of PDF pages [s SetAlignment: e_pthorizontal_left vertical_alignment: e_ptvertical_center]; PTColorPt *pt = [[PTColorPt alloc] initWithX: 0 y: 0 z: 0 w: 0]; [s SetFontColor: pt]; [s SetRotation: 180]; [s SetAsBackground: NO]; //only stamp first 2 pages PTPageSet *ps = [[PTPageSet alloc] initWithRange_start: 1 range_end: 2 filter: e_ptall]; [s StampImage: doc src_img: img dest_pages: ps];
Stamp a PDF File
Full code sample which shows how to stamp PDF pages with text, images, or with other PDF pages and how to add new content (or watermark).
Stamper can be used for PDF pages with text, images, or with other PDF content in only a few lines of code. Although Stamper is very simple to use compared to ElementBuilder/ElementWriter it is not as powerful or flexible. In case you need full control over PDF creation use ElementBuilder/ElementWriter to add new content to existing PDF pages as shown in the ElementBuilder sample project.
