Scanning

With most scanners, you can directly insert a scanned picture into a document. Scanned images are embedded in the document in PNG format.

Make sure the scanner is supported by the SANE system on Linux or other UNIX-like operating systems, or by TWAIN if you are using Windows. Note also that either of these must already be configured on the machine running OpenOffice. If more than one scanner or equivalent device is present, you can select the source from Insert → Picture → Scan → Select Source.

To insert an image from the scanner:

1. Prepare the image on the scanner and make sure that the scanner is ready.
2. Choose Insert → Picture → Scan → Request.
3. The rest of the procedure depends on the scanner driver and interface. You will normally be required to specify the resolution, a scan window, and other options. Consult the scanner’s documentation for more information.
4. When the image is scanned, Draw places it on the page. At this point, it can be edited like any other image.
