We recently upgraded our version of image magick from 6.5.1 to 6.5.7 (via karmic->lucid ubuntu upgrade). One of the commands we rely on is resizing an image and then placing it on top of another image: composite -gravity 'Center' -resize '304x202!' watermark.png -size '320x213' base.jpg result.jpg In this example we are expecting a r...

So I can't afford using the classical embedding by using the following: <html> <img src="m...

Hey all, I would like to measure the time it takes for an image to appear on-screen in Java. I can override the paint() method and see how long that method takes to execute, but I am not sure if the image is on the screen at the end of that method. Basically, I want to fill these requirements: Time to show an image on-screen is cons...

I've read a number of questions on finding the colour palette of an image, but my problem is slightly different. I'm looking for images made up of pure colours: pictures of the open sky, colourful photo backgrounds, red brick walls etc. So far I've used the App Engine Image.histogram() function to produce a histogram, filter out values ...

I read somewhere in Google's reference (and I can not find it again) that the shadow for the map marker should be at a 45 degree angle. What is the transformation to apply to the original image to achieve this? By eyeball it looks like it could be a horizontal shear of about 50% followed by a vertical compression to 50%, but I suspect it...
