Stamp Annotations ​

Stamp annotations add seal-like marks on PDF pages. You can use PDF standard stamps or custom bitmaps and images.

Standard Stamps ​

PDF defines standard stamp icons via setIconName():

Icon NameDescription
"Approved"Approved
"AsIs"As is
"Confidential"Confidential
"Departmental"Departmental
"Draft"Draft
"Experimental"Experimental
"Expired"Expired
"Final"Final
"ForComment"For comment
"ForPublicRelease"For public release
"NotApproved"Not approved
"NotForPublicRelease"Not for public release
"Sold"Sold
"TopSecret"Top secret

Example: Standard Stamp ​

java
import com.foxit.sdk.common.fxcrt.RectF;
import com.foxit.sdk.pdf.PDFPage;
import com.foxit.sdk.pdf.annots.Annot;
import com.foxit.sdk.pdf.annots.Stamp;

PDFPage page = doc.getPage(0);

RectF rect = new RectF(100, 600, 280, 660);
Stamp stamp = new Stamp(page.addAnnot(Annot.e_Stamp, rect));

stamp.setIconName("Approved");
stamp.setBorderColor(0xff009900);
stamp.setContent("已批准");
stamp.resetAppearanceStream();

Custom Bitmap Stamp ​

Use setBitmap() with any android.graphics.Bitmap:

java
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import com.foxit.sdk.common.fxcrt.RectF;
import com.foxit.sdk.pdf.PDFPage;
import com.foxit.sdk.pdf.annots.Annot;
import com.foxit.sdk.pdf.annots.Stamp;

PDFPage page = doc.getPage(0);

RectF rect = new RectF(100, 400, 300, 500);
Stamp stamp = new Stamp(page.addAnnot(Annot.e_Stamp, rect));

Bitmap bitmap = BitmapFactory.decodeFile("/sdcard/my_stamp.png");
stamp.setBitmap(bitmap);
stamp.resetAppearanceStream();

Stamp via Image Object ​

setImage() uses the SDK Image object with frame index and compression:

java
import com.foxit.sdk.common.Image;
import com.foxit.sdk.common.fxcrt.RectF;
import com.foxit.sdk.pdf.PDFPage;
import com.foxit.sdk.pdf.annots.Annot;
import com.foxit.sdk.pdf.annots.Stamp;

PDFPage page = doc.getPage(0);

RectF rect = new RectF(100, 400, 300, 500);
Stamp stamp = new Stamp(page.addAnnot(Annot.e_Stamp, rect));

Image image = new Image("/sdcard/stamp_image.jpg");
stamp.setImage(image, 0, 0);
stamp.resetAppearanceStream();

Stamp Rotation ​

java
int rotation = stamp.getRotation();
stamp.setRotation(45);
stamp.rotate(90);

stamp.resetAppearanceStream();
