I need some image programming advice

I am trying to build a high resolution image that consist of vertical lines from other images.

To be exact: I want to build an image that is 3888×2592 pixels. I want to build it using 3888 vertical lines that are 2592 pixels high. I have a folder with 3888 high resolution images and the new image should be build by extracting vertical line number one from the first picture, vertical line number two from the second picture, vertical line number three from the third picture and so on.

Here is a very simple illustration:

It would be possible to do this manually in photoshop. Open one image, cut the first column of pixels, paste in a new image and repeat 3888 times… But this is something that would be much easier by automation. Pseudo code:

- Create new image, 3888×2592

For n = 1 to 3888
- Open image number n
- Copy column number n (1×2592 pixels)
- Paste at column number n in new image
Next n

…the problem is that I have no idea what tool to use. Could this be programmed using automator and apple script? Using automation in photoshop? Or do I need to learn xcode and do it the hard way?

Preferably a solution that could be done on a Mac.

Any advice is appreciated!

Not sure why I would buy this one…

Cool city, cool people.

Best WLAN name ever

11.04.10 | 6 Comments

Today I decided to do a quick experiment. I’m on board the business class on a train bound for Göteborg. And as usual I have my trusted Huawei MiFi to give me internet access. With the recent fuzz around Firesheep I decided to do a quick test.

I renamed the SSID on my MiFi to “Free WiFi” and turned off the encryption. Launched Firesheep and waited. After less than fifteen minutes I had a Facebook account that I could log on to. On the status page from the MiFi I could see that I had three computers connected.

After a while I had another Facebook account I could log on to. But I just wanted my point proven. So I decided to stop and change the SSID again. This time I called my network “I will hack you with firesheep”. For some strange kind of reason nobody logged on to that one…

Update:
My headline is not correct. The best WLAN name ever is the last one in this list: Hilarious wifi network names

Quick App Review: Touch Retouch vs. Photo Fixer

11.01.10 | 3 Comments

You want to remove something from an image on your iPhone? As always, there’s an app for that. Here’s a quick test of two. Links: Touch Retouch and Photo Fixer.

Image 1: Remove the path

Touch Retouch

Brush a red layer on what you want to remove.

When you are satisfied hit “go”. Wait. And:

Photo Fixer

On this image it kept giving me a message about the fact that the area was too large. So I gave up.

Image 2: Remove the trashcan

Touch Retouch

Select and process:

Not completely satisfied, so I select more and get a decent result:

Photo Fixer

Touch Retouch

Photo Fixer:

Problem with too large selection. I decided to do it in several steps.

And got this result:

My conclusion after this quick test is that Touch Retouch is easier to use, is faster and gives better results than Photo Fixer.

But Photo Fixer is the new kid on the block and will probably mature as it gets updated etc. So keep an eye on both of them.

Update:
See the comments. One of my requested features is a sort of popup that shows what’s going on under your finger. The people behind TouchRetouch tells me that this is coming in version 2.0 later in November.

…in addition to lots of other improvements:
• 1:1 image viewer;
• Flickr, Facebook, Picasa, Twitter sharing;
• Clone Stamp tool;
• Finger move hint;
• Localized help;
• Application settings;
• Improved algorithm for large pictures;
• Landscape mode;
• EXIF data support.

Looking forward to that. And it’s very nice to see that both developers have contacted me because of this quick review. I’ll keep an eye on both these apps.
