vectorize hoto hanya ce mai ban sha'awa mai ban sha'awa ga masu zane-zane da masu zane-zane, ko da yake yana iya zama da amfani sosai ga masu fasaha na dijital, masu zanen tambari da kowane mai amfani da ke aiki tare da hotuna don shafin yanar gizon su ko masu sana'a. A cikin wannan sakon mun bayyana yadda ake yin shi.
Amma kafin magance wannan tambaya, ya zama dole a san abin da tsari yake vectorization. Yawancin hotunan da muke samu a Intanet ko kuma da muke lodawa a kwamfutocin mu suna da dige-dige ko pixels. Wannan yana nufin girmansa ya fi girma kuma ayyukan gyare-gyare suna da hankali da rikitarwa.

Menene vectorizing hoto?
Tsarin vectorization yana gudana canza hotuna da aka yi da pixels zuwa hotuna da aka yi da vectors. A fasaha, ya ƙunshi canza waɗannan pixels zuwa layi, lanƙwasa da maki. Don haka, hoton da ya kasance bulogi ɗaya ya zama ginshiƙi na tubalan waɗanda za a iya gyara su daidaikunsu. Ta wannan hanyar yana yiwuwa a cimma ƙarin daidaitaccen gyare-gyare da aikin ƙira.
Fayil ɗin da aka samo daga tsarin vectorization ana adana shi a cikin jerin takamaiman tsari: CDR, AI, SVG da EPS, musamman.
Akwai dabaru daban-daban don ƙirƙirar hoton vector: daga zana polygons da layi, don cika hoton da launi. Koyaya, lokacin da muke magana game da canza hoton da ke akwai, watau canza hoton bitmap zuwa vector, akwai hanyoyi guda biyu kawai don yin shi:
- Zana sifofin layi da lanƙwasa na siffa vector akan hoton.
- Yin amfani da auto vectorization kayan aiki. Yi shirye-shiryen hidima su ƙirƙiri sabon hoto a tsarin vector dangane da ainihin hoton.
Da zarar canji ya cika, ana iya ƙara ƙarar sakamako na ƙarshe ta hanyar zayyana siffofinsa, yin tasiri ga tsananin launi, laushi ko jaddada layinsa, da dai sauransu.

Yawancin masu zane-zane a duniya, duka masu son da ƙwararru, suna amfani da su akai-akai Corel zana. Hakanan ana iya amfani da wannan shirin don ƙirƙira da shirya hotunan vector. Da zarar mun shigar da ita a kan kwamfutarmu, tsarin vectorization yana da sauƙi, kawai bi waɗannan matakan:
- Da farko, muna buɗe shirin Corel Draw kuma mu ƙirƙiri sabon fayil,
- To dole ne mu shigo da hoton cewa muna so mu canza (tsararrun PNG ko JPEG suna da inganci).
- Muna danna hoton kuma zaɓi zaɓi Bitmap.

Babban kayan aiki kyauta don ƙirƙirar hotunan vector. Tare da Inkscape ba zai yiwu a sanya hoto a kan layi ba, dole ne a sauke shirin. Yin aiki da shi abu ne mai sauqi, kawai ka loda hoton da kake son yin aiki da shi sannan ka danna "Vectorize Bitmap".
Akwai filtata daban-daban guda uku don amfani: Ƙofar haske, gano gefen da ƙididdige launi.
