PUBLIC MARKS with tag pixel

The image-rendering CSS property provides a hint to the browser about the algorithm it should use to scale images. It applies to the element itself as well as any images supplied in other properties for the element. It has no effect on non-scaled images.

Using Paper.js you can easily work with the colors of individual pixels of Raster items.

When using GDI+ method you can optimize the process of bitmap manipulation  seven  times.I am implementing an image scaling algorithm at my University Seam Carving . While working on this project I realized that simply accessing pixels by the GetPixel and SetPixel methods is too slow.

The Bitmap class has GetPixel and SetPixel methods that let you acquire and change color of chosen pixels. Those methods are very easy to use but are also extremely slow. My previous post gives detailed explanation on the topic, click here if you are interested. Fortunately, you don’t have to use external libraries (or resign from .NET altogether) to do fast image manipulation. The Framework contains a class called ColorMatrix that lets you apply many changes to images in an efficient manner. Properties such as contrast or saturation can be modified this way. But what about manipulation of individual pixels? It can be done too, with the help from the Bitmap.LockBits method and the BitmapData class… A good way to test individual pixel manipulation speed is color difference detection. The task is to find portions of an image that have color similar to some chosen color. How to check if colors are similar? Think about color as a point in three dimensional space, where axis are: red, green and blue. Two colors are two points. The difference between colors is described by the distance between two points in RGB space.

Due to the amount of features and level of abstraction, I knew that creating this map would be a great test of my proficiency with Mapbox Studio, as well as Studio's own limits. By diving into the deep end, I learned some useful strategies.

Wedding, despite what its name may suggest, is not a very pretty part of Berlin. It’s drab, seedy, and has long been among the city’s poorest areas. Today, it’s home to a large immigrant population, mostly Turks, as evidenced by the kebab houses and hookah bars that line its gray streets.
