resize - Calculte new width and height of the video based on the original width, height and ratio -


after searching through - wasn't able find answer i'll give shot here.

i need resize desktop video in order feet on mobile screen, let's original width of video 1915 , original height 1075, calculated aspect ratio:

aspectratio = (width/height); aspectratio = 1.78;

now mobile screen resolution is: height = 1609, width = 1080.

how can resize video in order keep same aspect ratio??

thank you

aspectratio = (width/height)

you want aspectratio 1.78, if want prevent stretching or cropping.

and, max new height 1609 , max new width 1080, so:

1.78 = (1080/height) height = 1080/1.78 = 606.74...

or

1.78 = (width/1609) width = 1.78*1609 = 2864.02...

so, can have 1080x606.74 (which fits on screen), or 2864.02x1609 (which doesn't fit).

so, answer 1080x606.74...

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
