JPEG, TIFF, PSD, BMP, PICT, PNG, ndi GIF ikufotokozedwa
Kodi mumasokonezeka ndi mtundu wanji wa mafilimu omwe mungagwiritse ntchito, kapena mumadabwa kuti kusiyana kotani kuli pakati pa JPEG , TIFF, PSD, BMP, PICT, ndi PNG?
Nazi njira zowonjezera:
- Ngati zithunzizo zapangidwa pa webusaiti kapena pafoni, gwiritsani ntchito JPEG , PNG, kapena GIF.
- Ngati zithunzizo ziwonekere muzinthu zosindikizidwa, gwiritsani ntchito TIFF.
- Ngati mukufuna kusunga ndondomeko yosasinthika, sankhani mapulogalamu anu a fayilo . monga .PSD kwa Photoshop,
Pano pali kufotokozedwa mwachidule kwa mafayilo a mafayilo omwe amagwiritsa ntchito, pamodzi ndi maulumiki omwe mungatsatire kuti mudziwe zambiri:
Nthawi yogwiritsa ntchito JPEG
Magulu Ogwirizana a Zithunzi (JPEG kapena JPG) ndi abwino kwambiri pa zithunzi pamene mukufunikira kusunga kukula kwa fayilo ndipo musakayikire kusiya khalidwe linalake locheperako kukula. Kodi fayilo imakhala yaying'ono bwanji? JPEG nthawi zambiri imawoneka ngati "yotaya". Mwachidule, pamene fayilo ya JPEG imalengedwa compressor amawoneka chithunzi, amadziwika malo amitundu yosiyanasiyana ndikugwiritsa ntchito m'malo mwake. Mitundu yapamwambayi ndi mitundu yomwe sinawonedwe ngati yowonongeka, "kotero, kuchuluka kwa maonekedwe a zithunzi mu fano kumachepetsanso zomwe zimachepetsa kukula kwa fayilo.
Pamene fayilo ya JPG imalengedwa nthawi zambiri mumafunsidwa kuti muyambe kuika khalidwe labwino monga Photoshop Image zomwe mungasankhe zomwe zili zoyambira 0 mpaka 12. Chilichonse pansi pa zisanu chikhoza kuwonetsa chithunzi chojambulidwa chifukwa chidziwitso chochuluka chikuponyedwa kuti tipewe kukula kwa fayilo. Chilichonse pakati pa 8 ndi 12 chimayesedwa ngati njira yabwino.
JPEG si yoyenera mafano okhala ndi malembo, mabala akuluakulu, kapena maonekedwe osavuta chifukwa mizere yowopsya idzaphwanyika ndipo mitundu ikhoza kusuntha. JPEG yokha imapereka zosankha za Baseline, Baseline Optimized, kapena Progressive.
- Baseline (Standard) - Fomu iyi ya JPEG imadziwika ndi onse osatsegula pa Webusaiti.
- Zokonzedweratu zapamwamba - Njirayi ya JPEG imapereka mtundu wokongola komanso kupanikizika pang'ono. Izo zimathandizidwa ndi osatsegula onse amakono koma sizinali zothandizidwa ndi makasitomala oyambirira kwambiri pa Webusaiti. Ndi kusankha kwanu kwa JPEG mafayilo lero.
- Kupita patsogolo - Kumapanga fayilo ya JPEG yomwe imawonetsa pang'onopang'ono pamene ikumasula, kuyambira yowonongeka, ndipo pang'onopang'ono imawoneka ngati ikuwongolera. Sizimapangitsa fano kupopera mofulumira, koma ikhoza kupereka chithunzithunzi cha liwiro kuyambira pomwe chithunzichi chimasungidwa pang'onopang'ono. Ndi ambiri omwe amagwiritsa ntchito intaneti pa maulendo othamanga kwambiri masiku ano, Progressive JPEG sichitha kugwiritsidwa ntchito.
Nthawi yogwiritsa ntchito TIFF
TIFF (Tagged Image File Format) ndi yabwino kwa mtundu uliwonse wa bitmap (zochokera pa pixel) zojambulidwa kuti zisindikizidwe chifukwa mawonekedwe awa amagwiritsa ntchito mtundu wa CMYK. TIFF imapanga mafayilo akulu chifukwa cha chisankho chofanana cha 300 ppi popanda kutaya khalidwe. TIFF imasungiranso zigawo, alpha poyera, ndi zina zomwe zimapangidwa kuchokera ku Photoshop. Mtundu wambiri wowonjezera womwe umasungidwa ndi mafayilo a TIFF amasiyana m'mawonekedwe osiyanasiyana a Photoshop, choncho funsani thandizo la Photoshop kuti mudziwe zambiri.
Nthawi yogwiritsira ntchito PSD
PSD ndi mtundu wa Photoshop. Gwiritsani ntchito PSD pamene mukufuna kusunga zigawo, kuwonetsetsa, zigawo zosinthika, masks, kudula njira, zojambula zosanjikizana, zojambula, zolemba, ndi mawonekedwe, ndi zina zotero. Kumbukirani, zolembazi zikhoza kutsegulidwa ku Photoshop ngakhale osintha zithunzi adzatsegula iwo.
Nthawi yogwiritsira ntchito BMP
Gwiritsani ntchito BMP kwa mtundu uliwonse wa bitmap (zozikidwa pazithunzi). BMPs ndizithunzithunzi zazikulu, koma palibe kutayika mu khalidwe. BMP ilibe phindu phindu pa TIFF, kupatula ngati mungagwiritse ntchito pa Windows wallpaper. Ndipotu BMP ndi imodzi mwa mafano omwe amasungidwa kuyambira masiku oyambirira a makina a makompyuta ndipo nthawi zambiri sagwiritsidwa ntchito masiku ano. Izi zikufotokozera chifukwa chake nthawi zina zimatchulidwa kuti "maonekedwe".
Nthawi yogwiritsira ntchito PICT
PICT ndi ya kalembedwe yakale ya Mac, yomwe imagwiritsidwa ntchito pafupipafupi, Mofanana ndi BMP ya Windows, PICT siigwiritsidwe ntchito masiku ano.
Nthawi yogwiritsa ntchito PNG
Gwiritsani ntchito PNG pamene mukufunikira kukula kwa mafayilo osapangidwira. Mafayi a PNG amakhala ochepa kuposa mafano a TIFF. PNG imathandizanso al transparent (m'mphepete mwachangu) ndipo inakonzedwa kuti ikhale yojambula zithunzi pa Web. Dziwani kuti ngati mukufuna kusunga bwino , muyenera kusunga fayilo yanu ya PNG monga PNG-24 osati PNG-8. PNG-8 ndi yothandiza kuchepetsa kukula kwa mafayilo a mafayili a PNG pamene simusowa kuwonetsetsa, koma ali ndi zofanana zosiyana ndi ma fayilo a GIF .
PNG mtundu umagwiritsidwanso ntchito popanga zithunzi za iPhones ndi iPads. Dziwani kuti zithunzi sizimapereka mtundu wonse wa png. Chifukwa chake ndi png ndi zopanda pake, kutanthauza kuti kuli kochepa ngati kulimbikitsidwa kulikonse komwe kumagwiritsidwa ntchito ku fano la png lomwe limakhala ndi zazikulu zazikulu kuposa mafayilo awo .jpg.
Nthawi yogwiritsira ntchito GIF
GIF Gwiritsani ntchito zithunzi zosavuta pa Web kuti musakhale ndi mitundu 256. Mafayi a GIF nthawizonse amachepetsedwa kukhala 256 mitundu yapadera kapena yocheperapo ndipo amapanga zochepa kwambiri, zojambula zojambula za Webusaiti . GIF ndi yabwino kwa mabatani, ma chart kapena zithunzi, zojambulajambula, zojambula, ndi malemba. GIF imagwiritsidwanso ntchito pa zojambula zazing'ono, za compact Web. GIF sayenera kugwiritsidwa ntchito kwa zithunzi ngakhale pali kubwezeretsedwa kwa zithunzi za GIF ndi GIF Masewero chifukwa cha kuwuka kwa mafoni ndi zachikhalidwe.
