camera - How to resize image in Ionic 3 without quality reduce and target width and height? -


i want reduce size of images taken camera api quality reduce not good. best thing reduce resolution don't want use target width , height images.

for example, want image width 1280 , image height change automatically ratio, in api should use exact width , height.

how can change height dynamic image ratio???

for now, use code:

 this.camera.getpicture({   quality: 60,   destinationtype: this.camera.destinationtype.file_uri,   sourcetype: sourcetype,   mediatype: this.camera.mediatype.picture,   targetwidth: 1280,   targetheight: 1280,   encodingtype: this.camera.encodingtype.jpeg,   savetophotoalbum: (source === picturesource.camera),   allowedit: true })

i use image resizer native api in camera , works. when value assign width , height turn greater 1 target value , adjust 1 original ratio.. here code: 

 this.camera.getpicture({   destinationtype: this.camera.destinationtype.file_uri,   sourcetype: sourcetype,   mediatype: this.camera.mediatype.picture,   encodingtype: this.camera.encodingtype.jpeg,   savetophotoalbum: (source === picturesource.camera),   allowedit: true })   .then(imageuri => {     this.imageresizer.resize({       uri: imageuri,       quality: 60,       width: 1280,       height: 1280     }).then(uri => handler(uri))   })   .catch(error => console.warn(error))

}

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
