    2,000 pixel firing script munka, árazás ebben: EUR

    Adott egy motor, amit Adult Video Script-nek hívnak. Sajnos egyetlen nagyon fontos elemet kihagytak a fejlesztők ebből a motorból, mégpedig azt, hogy egy videót több kategóriába is fel lehessen tölteni, ( ne csak egybe). PHP és Smarty-n alapuló a cucc. Ha valaki meg tudja ezt oldani, annak adok FTP hozzáférést, és kipróbálhatja tudását :) Max költségkeret 30- 40 USD körül.

    QGIS modul python Véget ért left

    Agráriumban használatos differenciált műtrágya-kijuttatási térkép generáló python script kellene nekem, amit pl. QGIS-ben tudok futtatni. Multipolygon shape tetszőleges rekordjait kellene összeolvasztani automatizáltan bizonyos szempontok szerint. Eddig is meg tudtam oldani, csak automatizálni szeretném, ami programozást jelent, ahhoz viszont nem értek.

    Helló! Egy weboldal készítésével szeretnélek megbízni. Az oldalon kaleidoszkóp képeket lehet rajzolni. Maga a rajzoló rész egy Java applet, beágyazva a weblapba. Az applet kész van, a mérete 1000x550 pixel, de ezt könnyű megváltoztatni. A weblap csak néhány oldalból állna kb. úgy mint ez: Lenne egy főoldal, néhány képpel, ami bemutatja a programot, mit lehet vele csinálni, lenne egy lista a featurokról, stb. Lenne egy draw, vagy valami hasonló feliratos gomb, amivel a rajzoló oldalra lehetne jutni. Ez úgyanúgy nézne ki mint a főoldal, csak a tartalom helyén az ...
