Image Maps Ndi Zongokhala Zambiri Zomwe HTML Tags

Mapu a zithunzi ndi njira yosangalatsa komanso yosangalatsa yothetsera Webusaiti yanu, ndiwo nawo, mukhoza kuwongolera zithunzi ndikupanga zigawo za zithunzizo kuti ziwoneke pazinthu zina za intaneti. Ngati muli mu pinch ndipo simukufuna kukopera mapu a mapu, kulenga mapu pogwiritsa ntchito malemba a HTML ndi owongoka.

Mufuna fano, mkonzi wazithunzi ndi mtundu wina wa HTML editor kapena olemba mauthenga. Ojambula ambiri a zithunzi adzakuwonetsani makonzedwe a mbewa yanu pamene mulozera mu fano. Deta yolumikiza izi ndi zonse zomwe mukufunikira kuyamba ndi mapu a zithunzi.

Kupanga Mapu a Chithunzi

Pangani mapu ajambula, choyamba sankhani chithunzi chomwe chidzakhala maziko a mapu. Chithunzicho chiyenera kukhala "kukula kwakukulu" -ndiko, musagwiritse ntchito chithunzi chachikulu kwambiri moti osatsegulayo adzachiyesa.

Mukayika chithunzichi, mudzawonjezera chidziwitso chowonjezereka chomwe chimadziwika bwino ndi mapu:

Mukamapanga mapu ajambula, mukulenga malo omwe amawonekera pa chithunzichi, kotero mapulogalamu a mapu ayenera kulumikizana ndi kutalika ndi kupingasa kwa chithunzi chomwe mwasankha. Mapu amathandiza mitundu itatu yosiyanasiyana ya mawonekedwe:

kagawo kakang'ono kapena kachigawo kakang'ono kamodzi
poly-polygon kapena chiwerengero chamagulu
bwalo-bwalo

Kuti mupange madera, muyenera kudzipatula ndizomwe mukukonzekera mapu. Mapu akhoza kukhala ndi malo amodzi kapena angapo omwe afotokozedwa pa chithunzi chomwe, pamene chododometsa, mutsegule watsopano.

Kwa mapupala , mumapanga mapepala apamwamba kwambiri kumanzere ndi kumunsi. Mipingo yonse yayikidwa monga x, y (pamwamba, pamwamba). Kotero, pa ngodya yakumtunda yakumanzere 0,0 ndi ngodya ya kumanja ya pansi 10,15 mukhoza kufalitsa 0,0,10,15 . Mumaziphatikiza pa mapu:

Kwa polygon , mumapanga mapepala a x, y yodalumikiza mosiyana. Wosatsegula Webusaitiyi amangodzigwirizanitsa ndondomeko yotsiriza ya mipata ndi yoyamba; chirichonse mkati mwa makonzedwe awa ndi mbali ya mapu.

Maonekedwe ozungulirana amangofuna ma coordinates awiri, monga timabukusitiki, koma kuti tizilumikizako kachiwiri, mumatchula chigawo choyambira kapena mtunda kuchokera pakati pa bwalo. Kotero, kuti ukhale ndi bwalo ndi pakati pa 122,122 ndi malo a 5 mungathe kulemba 122,122,5:

Madera onse ndi mawonekedwe angaphatikizidwe pa mapu omwewo:

Mapu a zithunzi anali ofala kwambiri mu nyengo ya Web 1.0 ya m'ma 1990 mpaka mapepala oyambirira a 2000s-mapangidwe kawonekedwe amapangidwa maziko a webusaiti yoyendera. Wojambula angapange chithunzithunzi cha mtundu wina kuti asonyeze zinthu zam'ndandanda, kenako ikani mapu.

Zochitika zamakono zimalimbikitsa kuti anthu azikonzekera ndi kugwiritsa ntchito mapepala apamwamba kuti asamayidwe mafano ndi ma hyperlink pa tsamba.

Ngakhale mapu a mapu adakali othandizidwa muzotsatira za HTML , kugwiritsa ntchito mafoni apamwamba ndi zinthu zing'onozing'ono zapangidwe kungayambitse mavuto osadziwika amtundu ndi mapu a zithunzi. Kuphatikizanso, mavuto amtunduwu kapena zithunzi zowonongeka zimapindulitsa mtengo wa mapu a zithunzi.

Kotero, omasuka kuti mupitirize kugwiritsa ntchito teknoloji yabwinoyi, yomveka bwino podziwa kuti pali njira zowonjezera zowonjezera zomwe zikugwiritsidwa ntchito ndi olemba Webusaiti.
