image processing - Custom halftones algorithm on laser printers -


excuse naivety possible hack laser printer driver/firmware implement custom dithering instead of embedded default ones?

if postscript laser printer might able use sethalftone operator use different threshold array screens.

if want use dithering or instead need 'hack' code. i've no doubt possible, enormously difficult , mind pointless.

if don't technique in printer use ghostscript render postscript grayscale image, apply technique like, wrap resulting 1 bit per pixel image postscript , send printer. because image monochrome no further screening applied.

if talking colour can same, you'll have produce separated output , recombine halftoned images one.

i should point out printer manufacturers expend reasonable degree of effort in getting passable quality output, taking characteristics of print technology account. won't impossible better, you'll have have idea doing.

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
