Kusintha JPEG Mafunso Ofala
Kodi mtundu wa m'mawu oyambirira umakhudzana ndi kusinthika?
+
Amachita. JPEG ndi codec yofanana ndi JPG pansi pa chida chowonjezera - DCT yofanana, tambala yofanana yowerengera, palibe chomwe chimasintha ndi dzina la fayilo. Izi ndi zomwe zimasankhidwa ngati mirror ikhoza kuchitidwa polembanso fayilo kapena kufunikira kuchotsa koyamba.
Pali china chilichonse chokhudzana ndi JPEG chomwe chiyenera kuzindikira?
+
Yes — the.jpeg ndi.jpg zowonjezera ndi chimodzimodzi bitstream, choncho palibe apa amachita mosiyana ndi.jpg — zosintha zokha za dzina la fayilo. Kuyenera kukhala nthawi yoyenera kuti muchepetse chinthu chomwe simungathe kubwezeretsa.
Kodi ndi nthawi iti imene ndikufuna kuzungulira m’malo mozungulira?
+
Kusintha kwa sken kapena kujambula kwa webcam komwe kunatuluka mozungulira, kupanga ma pairs ozungulira kuchokera ku chinthu chimodzi, kapena kugwirizana ndi mfundo yoyang'anira ku layout. Ngati ma contents ali ndi malemba, ma logo kapena ma digito, onetsetsani kuti zotsatirazo - zomwe zimawonekanso.
Kodi ndingapeze owona angapo pamodzi?
+
Ndiyo. The chimodzimodzi axis ndi kuchitidwa kwa aliyense wapamwamba mu gulu, amene ndi mmene inu kukhazikitsa zonse zosunga zobwezeretsera mirrored ziwonetsero zazithunzi mu mphindi imodzi m'malo mwa mmodzi pa nthawi.
Kodi chimachitika ndi EXIF ndi mtundu wa profile deta?
+
EXIF ya kamera (ISO, shutter, lens, GPS) ndi ICC profile yophatikizidwa imapita ku default, chifukwa kuchotsa profile ndi komwe kumachititsa kuti mabala azisintha pa kulowanso.

No. Kusintha JPEG ndi ufulu popanda akaunti, palibe watermark pazotulutsa ndi palibe khoma lolembetsa m'mbuyo mwa kutsitsa. Kutsitsa kumatha kuchotsanso nthawi yochepa pambuyo pomaliza ntchito.
Kodi pali malire a kukula kwa fayilo pa Kusintha JPEG?
+
Yai: maakaunti aulere amapanga zithunzi mpaka ku 5 MB, zomwe zimakhudza kwambiri kamera iliyonse JPG ndi foni; ntchitoyi imachitika ndi libjpeg-turbo ndi libwebp, mabuku omwewo omwe wolemba deta amagwirizana nawo. Mafayilo akuluakulu ndi chinthu chimodzi chomwe chimalepheretsa chida chosalipira, ndipo chida chokha chili ndi fayilo imodzi kuposa fayilo imodzi.
Nchifukwa chiyani malo a PNG amalandira Kusintha JPEG?
+
PNG.to imapangidwa m'njira yomwe mumagwiritsa ntchito pamene simungathe kuwononga pixel: osatha, alpha-oyenera, ndi yankho loyenera kwa zithunzi zazithunzi, ma logo, line art ndi chilichonse chomwe chili ndi maziko olimba. Ntchito ya chithunzi siyimangokhala ndi gawo limodzi: anthu amafika kuti asinthire mtundu ndi kuchoka kufunikira chithunzi cha mtundu wina, kulemera kosiyana kapena mtundu wina. Kuyendetsa Kusintha JPEG pamodzi ndi kutsitsa, ma caps amtundu umodzi ndi akaunti imodzi ndichifukwa chake ndi apa ndipo si pa tabu yachiwiri.
Kodi ndingachite chiyani ndi zotsatirazi pamene Kusintha JPEG yatha?
+
Wosintha patsamba lino amasintha zithunzi ku PNG, JPG, WebP, GIF ndi SVG - zomwe ndi njira yomwe lamulo la kuwala kwa chilengedwe limapangidwa. Izi ndi njira yomwe anthu ambiri adapita, ndipo amachita izi pambuyo pa Kusintha JPEG kuposa kale, kumatanthauza kuti kusintha kwa ntchito kumachokera ku fayilo yomwe mwamaliza kukhazikitsa.
Kodi Kusintha JPEG pano ndi chinthu chomwecho chomwe masamba a sibling amayendetsa?
+
Magalimoto amagawana - mabuku omwewo, ogwira ntchito omwewo, ma limits omwewo. Zosiyana ndi malangizo, ndipo malangizowa amayamba kuchokera ku chinthu chimodzi chokhudza mtundu womwe umagwiritsidwa ntchito patsamba lino: palibe slider yabwino yosayenera - PNG imayenda m'mphepete mwa maulendo a bit-exactly, choncho chinthu chokhacho chomwe chimasintha mtengo wanu ndi kukula kwa fayilo. A PNG sitepe amaganiza za komwe PNG ndi malo abwino komanso komwe si, ndipo lamuloli limatanthauza zambiri kuposa batani.
Kodi ndiyenera kukhala ndi akaunti, ndipo kodi zinthu zina zimasunga?
+
Sichingakhale akaunti, ndipo palibe chomwe chimasunga: zotsitsa zimachotsa ntchito za ogwira ntchito pambuyo pomaliza ntchito, ndipo palibe chomwe mumapanga chimasinthidwa, kupezeka kapena kugwiritsidwa ntchito kwa chilichonse. Maakaunti aulere alipo kwa mbiri ndi kukula kwa batani, osati kulowa.
