It was the afternoon of HackDay… and I’d tried a couple of hack<\/a> ideas<\/a> without a massive amount of success. I wanted to have something functional to show by the end of the day, so thought I’d give something easy a try.<\/p>\n

I’d spent quite a bit of the morning getting to know the Windows Mobile camera API, so I thought I’d try and use it in an application. <\/p>\n

Background<\/b>
\nMy Windows Mobile cameraphone comes with a basic camera app. Then you can do what you want with your photos. <\/p>\n

The idea<\/b>
\nI thought I’d try writing an alternative camera app that makes it easier to do some things with photos – such as uploading to flickr<\/a>, posting to a WordPress<\/a> blog, sending by email, and so on.<\/p>\n

Why?<\/b>
\nWithout sounding like a Kodak advert, photos are more fun if you can share them. Anything that makes that easier could be a good thing. <\/p>\n

What was the plan?<\/b>
\nIt was fairly late in the afternoon by now, so I went back to managed code<\/a>. The app is based around using the CameraCaptureDialog<\/a> to get an image, then offer a bunch of things to do with it. <\/p>\n

flickr<\/b> – A chance to play with a web service – I went looking for the flickr API<\/a> for uploading pictures. <\/p>\n

This lets the user fill in the title, description and some tags and add it to their flickr space without needing to leave the camera app. <\/p>\n

And I reused some old GPS code<\/a> to add the ability to give flickr the location that the photo was taken<\/a>. This is quite neat – although you can use email to upload to flickr<\/a> from a phone, it would be much harder to include the location.
\n

\nWordPress<\/b> – Ah… erm… yeah… I kinda ran out of time and never got round to this. \ud83d\ude42
\n

\nemail<\/b> – A simple form that will let you send the photo as an attachment in an email.
\n

\nadd to Contacts<\/b> – Windows Mobile can attach pictures to contacts in the Outlook address book – so that someone’s picture is shown when they phone you, or next to emails and text messages that they send you. This form gives you a list of contacts in your address book, and lets you choose one for the photo to be added to.<\/p>\n

add GPS location to EXIF data<\/b> – flickr has a weird way of handling GPS location data – it doesn’t seem to use EXIF tags as you might expect, it has it’s own way. But I thought it might be nice to add the ability to add the GPS location where the photo was taken to the photo’s EXIF data. <\/p>\n

I managed to get the GPS location okay, but wasn’t able to add it to the photo. The .NET functions to add EXIF tags to photos, like SetPropertyItem<\/a> are not included in the .NET Compact Framework that you get on Windows Mobile, and I ran out of time before I could work out how to add the data in manually. <\/p>\n



\nAnd there it is. Not entirely finished, but by this point it was about 6pm on a Friday evening, and HackDay was over. <\/p>\n","protected":false},"excerpt":{"rendered":"
