Watermarks part 2

| No Comments

Do you know, I've just spent 40 minues making a great Blog entry on Watermarking.... then I hit the "go back a page in my browser" button instead of the backspace key... result? No more blog entry.

Lesson learned that hard way.... save your work regularly. It's not like I haven't been in IT for years and had multiple blue screens of death with loss of work as a result.... I should really learn!

Anyway.... Watermarking over multiple files.... Suhail asked me about this following a recent Blog entry on Watermarking.

I first thought of the "Document Processing" menu and the "Batch" commands option. But then I remembered......

Add or replace a watermark, with an open document

1. Choose Document > Watermark > Add.
2. (Optional) To apply the watermark selectively to individual pages, click Page Range Options. Then specify a page range and choose a Subset option, as needed.
3. Specify the watermark:

-------- Then do some noice formatting of the watermark ----------

7. (Optional) To apply the same settings to additional PDFs, click Apply To Multiple. Click Add Files, choose Add Files or Add Open Files, and then select the files. Then in the Output Options dialog box, specify your folder and filename preferences, and click OK.

Now, I can't quite remember if this feature extends back to say, Acrobat 7 but if not, use the Batch processing option, you can add Watermarks there...

Now.... in other news

1. Manchesterford United Town have been grouped with Celtic and some other chaps in the Champions League (that's proper football and United are the current Champions of Europe)

2. England seem to have finally learned how to play Cricket again, even if it's only the one day version of the game)

3. I'm running all over the counrty (OK not actually running... have you seen me run!) holding Acrobat seminars for Government departments and Public sector bodies.

These semainars have been great fun and are aimed just at showing the capabilities of Acrobat, mainly to people who have already purchased the product! Just look at this happy seminar attendee....


If you're working in the UK Public sector and think your team or office could do with a Lunch and learn type of session from Mr Spartacus, pop me a blog comment and I'll see what I can do.

The seminars are free and I promise I won't try to sell you anything.

Acrobat 9 Geo-whatnow PDFs?


Just a quickie, because I've been asked about geospatial PDFs.......

A geospatial PDF contains information that is required to georeference location data. When geospatial data is imported into a PDF, Acrobat retains the geospatial coordinates. With the coordinates, you can view and interact with the PDF to find and mark location data.

Geospatial data can be either vector or raster based or a combination of both. After you import geospatial data into Acrobat, you can use the data in a variety of ways:

* Find and mark location coordinates.
* Measure distance, perimeter, and area.
* Change the coordinate system and measurement units.
* Copy location coordinates to clipboard, and then use them to show locations in several web mapping services.
* Register a raster image to create a geospatially aware PDF.

You can create a geospatial PDF in one of these ways:

* Opening a geospatially enabled TIFF (GeoTIFF) or JPEG 2000 file
* Georegistering a PDF map or scan of geospatial data

When you open an imported file, measurements, point position, and length are displayed in geographic coordinates, which you can change, measure, and mark up. You can also assemble a PDF map from a variety of sources.
Open GeoTIFF and JPEG 2000 files

GeoTIFF files and JPEG 2000 files are raster images that you can import as new documents or as new layers to an existing document. Acrobat preserves the geospatial coordinates embedded in the file. These files retain their geospatial data when they are imported. If you import these files to existing documents, their coordinate system is converted to the coordinate system of the document.

1. Choose File > Create PDF > From File.
2. Select the geospatially enabled file to import.
3. Select settings, and then click OK.

Import shapefiles

You can import a shapefile as a new layer to an existing PDF. The shapefile must overlap with the current PDF map. Otherwise, it is not imported. If it overlaps only partially, only the part that overlaps the current PDF is imported.

A shapefile consists of several files with differing filename extensions. Acrobat requires both the SHP file and the DBF file for importing.

1. Open a PDF map, and choose View > Navigation Panels > Layers.
2. Select Option on the Layer sidebar and click Import As Layer.
3. Browse to the SHP file and select it.
4. Click Settings and change the Line Properties to a solid line and the line color to blue.

Georegister a PDF map

Georegistration enables you to take any PDF map and add coordinates that map to real-world locations. To georegister a map, you need the boundary coordinates of the map (latitude and longitude). You also need the projection scale on which the map is based. With this information, Acrobat can accurately transform the map to WGS 1984, the standard reference frame for earth.

1. Open a PDF that contains a map image, and note the projection that the map is based on.
2. Choose Tools > Analysis > Geospatial Registration Tool
3. Type a name, and then draw a neatline around the perimeter of the map.

A neatline separates a map from the rest of the page. It is commonly drawn around the map borders. The neatline defines the map area and allows you to remove parts of the page that are not relevant to the map. Or, select Use Page Bounds As Neatline to use the page border as the neatline. Move around the PDF by using either scroll bars or arrow keys. However, selecting another tool, such as the Hand tool or Zoom tool cancels the registration process.

4. Click one corner of the map, and in the Geospatial Registration dialog box, type the latitude and longitude coordinates for the first point. The coordinates define the area that is registered.
5. Click in at least two remaining corners, and type the latitude and longitude coordinates for each. Then click Next.
6. Select the associated coordinate system and units (projection scale) to associate with the map and click OK.

I'm almost lost for words, yeah, like that's going to happen. So the GB team have surpassed their target of 35 medals (at least that's what I heard the target was). More importantly, the colour of those medals has been the surprise, 16 Golds with a possible 2-3 more (being optomistic).

What I really have enjoyed though, is the cycling. I can't remember a time where Great Britain have been so dominant in an Olympic discipline. It's a wonderful change to see British athelets step into an arena and see the competition think... oh no, it's a Brit! Rare and lovely to watch. I was lucky enough to watch some of the cycling world championships in Manchester, many people were worried that the GB team had peaked too soon (myself amongst them) but we've shown how well we can prepare when the funding and setup is right.

Well done to all our sportsmen and women and a little thanks also to UK Sport who seem to have put all the right elements together.

Oh well, back to work!

Well, I couldn't let it go by, a dull game followed by Penalties......


You beauty!

Our good friends at Winsoft posted a note in a recent blog post of mine and I thought it was worth a full entry in and of itself...

Acrobat 9 is now also available for Middle Eastern languages.

These dedicated versions of Acrobat 9 gather all the characteristics of the US versions plus enhanced and advanced features to handle Middle Eastern languages (Right to Left direction, non-Roman text, Hindi digits, etc.).

More information on

Middle Eastern - Arabic
Middle Eastern - Hebrew
North African

Thanks Chaps!

It's been a while since I spent much time looking at Acrobat with reference to the AEC world...

One of the major announcements for Acrobat 9 that I didn't pick up on straight away was the support of the IFC file format in Acrobat Pro Extended (You'll recall, this is the replacement for Acrobat 3D). This is significant as it supports Building Information Modeling workflow's. This features allows you to share your 3D models via a pdf document and have full visualization and now object property data associated to the model. This allows us to develop functionality that will be supported by multiple 3D CAD applications on the market today. The IFC files formats that we are supporting are the IFC2x3 and IFC2x2.

IFC is an open standard data model where building information can be represented and shared between various processes and professions. It is a very dynamic, flexible model, and can be used from from early planning stages to a complete and very detailed model of the built environment.

So how does it work?

All you need access to is the IFC file. You do not have to have the native 3D CAD application installed on your computer. Just simply open Acrobat Pro Extended and drag and drop the IFC file into the open window. This will convert your model to pdf.

I can then zoom into an object and select that object and turn on my Model Tree (File - Navigation Panels - Model Tree). The result is now I can see all the IFC information associated to that particular object as shown below.


(Thanks to my colleague Jonathan Bowman for the image, check out his excellent blog, he is the Adobe Acrobat AEC Guru!)

So, you can see that's pretty straightforward The value of Acrobat Pro Extended is that it goes way beyond simple visualization. A lot of people want to compare us to current 3D viewers on the market. The value is that I am now able to access and utilise 89% of the worlds desktops as anyone with the Free Adobe Reader can also view, navigate and see the IFC information.

Of course, PDF is also a format that people are comfortable using, so one minute they're opening a PDF created from a Word document, the next it's a 3D file containing BIM information, easy peasy. No barriers to adoption!

Of course, we can also use all the other rich Acrobat functionality with the 3D model such as being able to combine this model with other documents, review and comment, collaborate, etc.
