Hiljuti palus \u00fcks meie lugejatest kirjutada Laraveli piltide \u00fcleslaadimise ja k\u00e4rpimise artikli. Varem avaldasin samal teemal artikli PHP \u00fcleslaadimiseks, k\u00e4rpimiseks ja pildi suuruse muutmiseks PHP-s<\/a>. Kuid Laraveli osas peame tegema muudatusi vastavalt Laraveli standarditele. Selles artiklis uurime, kuidas pilte Laravelis \u00fcles laadida ja k\u00e4rpida.<\/p>\n

Selle \u00f5petuse jaoks kavatsen kasutada kahte teeki – imgAreaSelect ja Intervention Image.<\/p>\n

imgAreaSelect<\/a> on jQuery pistikprogramm, mis v\u00f5imaldab pilte k\u00e4rpida<\/a>, valides pildi ristk\u00fclikukujulise ala. See on kerge pistikprogramm ja seda on lihtne kasutada.<\/p>\n

Teiselt poolt on sekkumispilt<\/a> kujutiste k\u00e4itlemise ja manipuleerimise teek. See teek aitab meil serveri poolel pilte luua, redigeerida ja komponeerida.<\/p>\n

Selles \u00f5petuses kasutan k\u00e4rbitud pildi ja sekkumise pilditeegi koordinaatide hankimiseks rakendust imgAreaSelect, et pilti tegelikult serveri poolel k\u00e4rpida vastavalt koordinaatidele.<\/p>\n

Alustamine<\/h3>\n

Alustamiseks oleksite pidanud installima Laraveli. Kui te pole veel loonud, installige see k\u00e4su kaudu:<\/p>\n

composer create-project --prefer-dist laravel\/laravel laravel-dev<\/code><\/pre>\n
\u00dclaltoodud k\u00e4sk seab teie jaoks Laraveli projekti nimega ‘laravel-dev’.<\/p>\n
J\u00e4rgmisena installige oma Laraveli projekti Intervention pilditeek. K\u00e4ivitage projekti juurkataloogist allpool olev k\u00e4sk.<\/p>\n
composer require intervention\/image<\/code><\/pre>\n
P\u00e4rast teegi installimist avage config\/app.php<\/code>fail ja lisage sellele j\u00e4rgmised read.<\/p>\n
Lisage $providers<\/code>massiivi selle paketi teenusepakkujad .<\/p>\n
InterventionImageImageServiceProvider::class<\/code><\/pre>\n
Lisage $aliases<\/code>massiivile fassaad .<\/p>\n
'Image' => InterventionImageFacadesImage::class<\/code><\/pre>\n
L\u00f5puks laadige alla pistikprogramm imgAreaSelect<\/a>. Kopeerige allalaaditud ZIP-failist pildid, CSS- ja JS-fail ning kleepige Laraveli projekti avalikku kausta. P\u00f5him\u00f5tteliselt peaks teie struktuur olema nagu allpool olev ekraanipilt.<\/p>\n
\"Kuidas<\/a><\/p>\n
Kuidas kasutada imgAreaSelect<\/h3>\n
Kuna kavatseme kasutada pistikprogrammi imgAreaSelect CSS-i ja JS-i, ehitame selle \u00fclesehituse. Looge resources\/views\/layouts\/app.blade.php<\/code>fail ja lisage sellesse allolev kood.<\/p>\n
