PDFWidget for 2.1

BrianO had created a PDFWidget for 1.3 (http://forums.arcgis.com/threads/12142-FSV-1.3-My-version-of-PDF-Widget-using-AlivePDF?highlight=print).

I have ported this to 2.1. I have commented out the portrait orientation option since the map image does not yet scale properly. That leaves landscape by default and it too is getting cut-off (see attached) on the bottom - so if anyone knows how to scale this properly please respond here!

I was receiving an 'Alpha channel not supported for now' error - you need to replace the logo.jpg (referenced on line 99 of the mxml) with your logo that has no alpha channel (I got mine to work by exporting the logo from photoshop....) - not sure what is going on here exactly.

Oh ya...you need to include the AlivePDF.swc library in your build path. I've attached the latest AlivePDF.swc here (0.1.5 RC). Don't forget to also add PDFWidget.mxml to the modules for building...

I don't think there is much that can be done in terms of scaling the image without distortion...sometimes the image will just not fill up the entire pdf. So I modified the placement of the titleblock and map. Now the titleblock is at the top and the map below...that way the map can never overlap the titleblock. If interested copy the code below and replace everything below '//create a landscape map' in the PDFWidget.mxml posted above...

else  //create a landscape map
    {
     //create landscape letter-size pdf and set margins
     landPDF=new PDF(Orientation.LANDSCAPE,Unit.MM,Size.LETTER);
     landPDF.setDisplayMode(Display.FULL_PAGE,Layout.SINGLE_PAGE);
     landPDF.setMargins(2,2,2,2);
     landPDF.addPage();
     
    
     //add PDF document metadata--most people never notice but give credit where due
     //and create a "well-formed" pdf document
     landPDF.setTitle(txtTitle.text);
     landPDF.setSubject(pdfSubject);
     landPDF.setAuthor(pdfAuthor);
     landPDF.setKeywords(pdfKeywords);
     landPDF.setCreator(pdfCreator);
     
     //draw neat line
     //landPDF.drawRect(new Rectangle(2,2,275,212));
     
     //draw title block rectangle
     landPDF.drawRect(new Rectangle(3,3,273,32));
     
     //add logo image
     landPDF.addImageStream(new myLogoJPG() as ByteArray,"DeviceRGB",null,3,5,40,0,0,1,Blend.NORMAL,null);
     
     //add title text entered in widget input
     landPDF.setFont(timesboldFont,22);
     landPDF.addText(txtTitle.text,50,10);
     
     //add subtitle text entered in widget input
     landPDF.setFont(timesFont,16);
     landPDF.addText(txtSubtitle.text,50,17);

This is a print sample that Mark H put together. I find it to be a very nice utility for trimming the map to get the print size correct. There are a few different pieces to get this to work but I would recommend downloading it and looking at the code to see how he trims the map. I use some of this code on my site and it has been very helpful for sizing the map correctly. Technically you don't need all of the pieces and you can just call his PrintMapUtil.as to return your map as a bitmap.

Thanks, I will look into that.

On a different note...is it possible to ensure the background colour set in the viewer gets exported to the PDF?

In my config.xml I have added a sixth element which designates the background colour....

<stylecolors>0xCCCCCC,0x777777,0x555555,0x333333,0xCCCCCC,0xBED2FF</stylecolors>

....but this does not make it onto the PDF.

Thanks!

Philipp,

I have found that you have to explicitly set the map objects background color before you take the snapshot.

Philipp,

I have downloaded the source code for PDF Widget and incorporated the AlivePDF.swc to libs. The widget is implemented error free, but does not proceed further after I click on the "Generate PDF" button.

Could you post the latest widget source code?

I haven't made any changes to the code that you have already implemented. Did you add the PDFWidget.mxml to the 'modules'? Also, once you click the 'Generate PDF' button there is no progress bar to let you know how long the process will take....for me it has been running anywhere from 5 seconds to about 25 seconds....

If anyone could chime in with the method on how to include certain widgets (ie, Roberts Dynamic Legend widget) on the resulting PDF that would be much appreciated. Export to PDF is great but certain maps simply require a legend to be printed (ie, zoning maps).

Thanks for any help!

Hey Nadeem,
Did you ever get this to work? I am having the same problem with the widget, it is not doing anything, when i click on Generate PDF. Thanks.

with the addition of this import statement:

import com.esri.viewer.ViewerContainer;

and changing this line (line 296):

landPDF.addImage(map,rsLand,2,35,0,0,0,1,false,ImageFormat.PNG,100,Blend.NORMAL,null);

to this:

landPDF.addImage(ViewerContainer.getInstance(),rsLand,2,35,0,0,0,1,false,ImageFormat.PNG,100,Blend.NORMAL,null);

it is possible to print everything that is visible on your map (ie, open widgets, legend, scalebar, navigation control and header). What I would like to do is to remove the header and navigation widgets from the resulting pdf....anyone have any ideas? Also, while I'm on the topic it would also be nice to see a north arrow in there....I guess that could be done now using the StaticImageWidget.....

Thanks!

I have figured out that if you take out the Logo's Image Bindable and ImageStream lines that are there in the mxml to show logo, the widget functionality proceeds and creates a PDF. Try it.

I am trying to implement this widget for my site. So far it works well.

I wonder if since there isn't really a way to see a progress bar to show when it is done generating the pdf, would there possibly be a way to make it open when it is finished? Any ideas would be greatly appreciated.
Thanks!

I think I have asked this before - but will try again....

I have this PDFwidget working so that all open widgets, navigation controls, scalebar and header get inserted on the map. I had to do this so that you could have the Dynamic Legend widget open and have it appear on the map. The drawback is that all other open widgets get included as well - including the actual PDFwidget!

It would be ideal to be able to remove the header and navigation widget and be able to choose which widgets to include. This is probably a tall order....and I am not sure how to go about this...

Thanks for any input!

Ahhh, seeing a dynamic legend printed on the map, now that would be good! Takes me back to the good ol' days.

thejones23,

Could you elaborate on how to use the PrintMapUtil.as in conjunction with AlivePDF? I'm already using the print sample you're talking about, but using it for the PDF is a bit beyond my understanding, especially since I'm really new to AlivePDF.

I'm having sandbox violations when I attempt to export if I have WMS in my operational layers that have skipgetcapabilities="true"

does this export to pdf support WMS?

The general problem is that Flash does not let you take a snapshot of a image (access its bitmap data) if it's loaded from another domain and the domain doesn't have a permissive crossdomain.xml file. You can work around this by using a proxy.

I am not entirely sure how to deal with proxy pages. this is not my area of expertise.
I have IIS on win7 and .net framework vers 2.0
I have downloaded the proxy pages for .net from here: http://help.arcgis.com/en/webapi/flex/help/index.html#/Using_the_proxy_page/017p0000000v000000/

and am trying to follow the instructions there. but is a bit convoluted. I need to create a new directory in IIS to put my proxy pages in, then convert to app? or does it mean the web app for flex viewer that I have running, that is referencing WMS from another server?
