Your general approach should work, but I’d highlight some details. Instead of your given list of colors, generate a number of color “bins” in the color spectrum to count pixels. Here’s another question that has some algorithms for that: Generating spectrum color palettes Make the number of bins configurable, so you can experiment to get … Read more
A typical python tool chain would be: read your images with with PIL transform them into Numpy arrays use Scipy’s image filters (linear and rank, morphological) to implement your solution As far differentiating the shapes, I would obtain its silhouette by looking at the shape of the background. I would then detect the number of … Read more
The selection of a particular filter for image processing is something of a black art, because the main criterion for judging the result is subjective: in computer graphics, the ultimate question is almost always: “does it look good?”. There are a lot of good filters out there, and the choice between the best frequently comes … Read more
http://jsfiddle.net/Log82brL/7/ #img { width: 100%; height: 100%; object-fit: cover; } object-fit: cover allows the replaced content is sized to maintain its aspect ratio while filling the element’s entire content box: its concrete object size is resolved as a cover constraint against the element’s used width and height.
Yeah, you could use it with the layout=fill option you mentioned. On this case, you’re gonna need to set an “aspect ratio” for your images <div style={{ position: “relative”, width: “100%”, paddingBottom: “20%” }} > <Image alt=”Image Alt” src=”/image.jpg” layout=”fill” objectFit=”contain” // Scale your image down to fit into the container /> </div> You can … Read more
You need to Close() the ZipStream after adding all the data you want to compress; it retains a buffer of unwritten bytes internally (even if you Flush()) that needs to be written. More generally, Stream is IDisposable, so you should also be using each… (yes, I know that MemoryStream isn’t going to lose any data, … Read more
I assume you are using the caption feature of Word, that is, captions were not typed in as normal text, but were inserted using Insert > Caption (Word versions before 2007), or References > Insert Caption (in the ribbon of Word 2007 and up). If done correctly, the captions are really ‘fields’. You’ll know if … Read more
You can add an onerror handler: <img src=”http://example.com/somejpg.jpg” onerror=”this.onerror = null; this.src=”./oops.gif”” /> Note: Setting onerror to null in the handler, so that the webpage doesn’t crash if oops.gif can’t be loaded for some reason.
As of API Level 24 they have added new methods (and updated the documentation) and flags to the WallpaperManager which allow you to set a Wallpaper not only to the home screen but also to the Lockscreen To set a Wallpaper to the Lockscreen use the new flag WallpaperManager.FLAG_LOCK, and one of the methods which … Read more
There is no direct way of converting an Image to UIImage. instead, you should treat the Image as a View, and try to convert that View to a UIImage. Image conforms to View, so we already have the View we need. now we just need to convert that View to a UIImage. We need 2 … Read more
