Display transparent image on axes (MATLAB) -

so have transparent image ( http://imgur.com/fyqslax ) want display on axes in matlab transperancy. this, used code below, works other transparent png images have: [a, map, alpha] = imread('fyqslax.png'); h = imshow(a, map) set(h, 'alphadata', alpha); this code however, not seem work image above. im guessing because has image being grayscale , having bitdepth of 1, resulting in map , alpha having nothing in (whereas other png transparent images have, have in map , alpha). if use this: a = imread('fyqslax.png'); h = imshow(a) a black background appears image should transparent. how display http://imgur.com/fyqslax transperancy on axes? edit: horchler's method worked; thanks!! if run imfinfo('fyqslax.png') , you'll see 'transparency' specified 'simple' , 'simpletransparencydata' set 0 ( false ). can't find documentation on this, think may indicate alpha channel has been compressed image data...

networking - Why does the number of links not matter in the transmission time of circuit switching? -

i reading book networking, , says that, in circuit switching environment, number of links , switches signal has go through before getting destination not affect overall time takes signal received. on other hand, in packet switching scenario number of links , switches make difference. spent quite bit of time trying figure out, can't seem it. why that? to drastically over-simplify, circuit-switched environment has direct line transmitter transmitted once connection has been established; imagine old-fashioned phone-call going through switchboards. therefore transmission time same regardless of hops (well, ignoring physical time takes signal move on wire, small since it's moving @ speed of light). in packet-switched environment, there no direct connection. packet of data sent transmitter first hop, tries calculate open route destination. passes data onto next hop, again has calculate next available hop, , on. takes time linearly increases number of hops. think sendin...

html - How can I use a CSS gradient on both top-left and top-right corners of my page? -

Image
i'm trying figure out how can use this: http://www.colorzilla.com/gradient-editor/ and use 1 in top-left corner of page, top-right. any appreciated. you can either like this (i stripped code out, best viewed in chrome), using 2 wrappers , applying gradient each (provided each ends transparent allow other show through). the gradient code used generate is: #wrapper { width:100%; height:500px; background: -webkit-radial-gradient(top left, ellipse cover, rgba(255,0,0,1) 0%,rgba(255,0,0,0) 50%); border:solid 1px red; } #inner { width:100%; height:500px; background: -webkit-radial-gradient(top right, ellipse cover, rgba(0,0,255,1) 0%,rgba(0,0,255,0) 50%); border:solid 1px blue; } here's demo result: alternately, combine both gradients 1 using colorzilla editor , using multiple color stops.
