Texture mapping bitmap to SVG path -

-

i have ordinary rectangular bitmap able use fill four-pointed svg path - mapped texture 4 corners of bitmap mapped 4 points of path , rest of image 'warped' accordingly.

i have been able fill svg rect same image , transform rect such bitmap transformed it:

<defs>   <pattern id="bmp" x="0" y="0" width="1" height="1">     <image x="0" y="0" width="100" height="100" href="mybmp.bmp"/>   </pattern> </defs> <rect x="0" y="0" width="100" height="100" fill="url(#bmp)" stroke="black" transform="skewx(10)"/>

when try use bitmap fill path though gets mapped bounding box of path shape , not 4 points of path itself:

<defs>   <pattern id="bmp" x="0" y="0" width="1" height="1">     <image x="0" y="0" width="100" height="100" href="mybmp.bmp"/>   </pattern> </defs> <path d="m 0 0 l 100 0 l 120 80 l 50 120 z" fill="url(#bmp)" stroke="black" />

is possible same effect first example (texture mapped corners of rectangle) in arbitrary path shape?

one solution give pattern viewbox content image gets scaled fit pattern bounds.

<svg>    <defs>      <pattern id="bmp" x="0" y="0" width="1" height="1"               viewbox="0 0 100 100">        <image x="0" y="0" width="100" height="100" xlink:href="http://www.placekitten.com/100/100"/>      </pattern>    </defs>    <path d="m 0 0 l 100 0 l 120 80 l 50 120 z" fill="url(#bmp)" stroke="black" />  </svg>

depending on shape of path, may need set preserveaspectratio="xmidymid slice". ensure pattern gets scaled size large enough cover whole path no gaps.

<svg>    <defs>      <pattern id="bmp" x="0" y="0" width="1" height="1"               viewbox="0 0 100 100" preserveaspectratio="xmidymid slice">        <image x="0" y="0" width="100" height="100" xlink:href="http://www.placekitten.com/100/100"/>      </pattern>    </defs>    <path d="m 0 0 l 100 0 l 120 80 l 50 120 z" fill="url(#bmp)" stroke="black" />  </svg>

Android volley - avoid multiple requests of the same kind to the server? -

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
