Yintoni GIFCA? GIF-umfanekiso 'VKontakte "hayi kuphela

Kulo nyaka uphelileyo, imfanekiso zibe yinxalenye zokuncokola nokuzonwabisa resource. Kule meko, abasebenzisi "VKontakte" kunye namanye amajelo loluntu abanomdla umbuzo oko SIFCO.

Ingcamango fomathi

GIF zinakho ziqala ngokuthi "codec axelelana anemifanekiso." It waphuhliswa CompuServe ngo-1987 ukuya ukuthumela ibitmaps ngapha komsebenzi womnatha.

Imifanekiso ulwandiso gif kungagcinwa ngaphandle kokuqhatha umgangatho uze ubale ukuya kwi 256 imibala zixhaphakileyo. Kuyenzeka ukuxhasa kwaye inani elikhulu shades kuphiliso xa une-mbala ezahlukeneyo isakhelo ngasinye, yaye zero ulibaziseko phakathi imifanekiso. Ifomati kubandakanya ukusebenza kunye nombala palette eqhelekileyo. Lo mfanekiso igcinwe ngentambo. Ngenxa iifayile LZW-zixinaniswe nge inani elikhulu kwimimandla yohlobo olunye kalula zixinaniswe. Lo mfanekiso abalahlekelwanga definition.

Advanced GIF-umfanekiso

Kuthetha ukuthini GIFCA ukuba umsebenzisi mihla, ukuba ngaba akukho oopopayi? Oku into afuna. Ngoko, kungekudala emva kokudalwa kwifomati kuye kwaphuculwa: ukusuka 1989 GIF iifayile-kunokuba ukubanamandla kwaye ziqulathe iindawo ngaphaya. Animated GIFCA - umfanekiso equlathe izakhelo ezininzi, ngokunjalo inkcazelo malunga nezihlandlo kwakunye naleyo ndlela zibekwa ngayo. Ngokuqhelekileyo, le nkqubo looped, kwaye emva kokuba show GIFCA ngokutsha.

Phakathi zemibala imibala zingabhengezwa ecacileyo. Kulo mzekelo, kubakhangeli zincwadi abasetyenziswayo izakubonisa imvelaphi kwimimandla unpainted. elubala Partial, inkxaso PNG, kuba gifok nobuntu: pixel isenokuba yagcwalisa okanye ngaphaya.

Apho kuyimfuneko GIF-format?

Ukwazi kanye oko GIFCA, sinokugqiba ukuba olu hlobo lomfanekiso kuluncedo kakhulu apho ifayile kufuneka buncinci bobukhulu. Le ndawo ke Internet: yokulandelana nezinto isantya kulayishwa amaphepha, abaphuhlisi bazama ukunciphisa ukusetyenziswa imifanekiso "enzima", wakhetha GIFCA ezilula.

Ifomati GIF kuqhelekile kuyilo web. Yinto efanelekileyo ekudluliseni imifanekiso emincinane, xa Vol. H. Abaqulathe isicatshulwa. ezihonjiswe kakuhle ezahlukeneyo imibhalo yamaqhosha - ukuba ezinye, njengokuba SIFCO. Kunjalo, GIF akafanelanga kusetyenziselwa ukugcina iifoto. Ukulungiselela le njongo JPEG efanelekileyo (JPG): Le fomati ayiphelelanga kwi inani lemibala displayable.

Animated SIFCO wayedla kuyilo websites. Bakwazi ukuphuma ipixels ezibonisa ngaphaya, GIF-umfanekiso uvumelane ngokugqibeleleyo uthotho neminye imifanekiso.

iimpawu technical

Yintoni GIFCA? Okokuqala, oko kuncitshiswa umfanekiso "ubunzima". Ifomathi LZW-ucinezelo, nto leyo evumela ukuba ukudibanisa nempinda pixels. Ngoko ke, imimandla bomzi ngakumbi, kokukhona iya kuncitshiswa umfanekiso. I algorithm ivumela ukunciphisa ubungakanani bit ezisibhozo-imifanekiso zemibala ngaphandle kokunikezela umgangatho: idatha abe inokubuyiselwa ngokupheleleyo. Njengoko kuba iifoto, lo umda imibala 256 ziya kuba vuhlayiseki.

LZW algorithm ofuna ngamayelenqe efanayo kwifayile ebizwa amabinzana, esabela kubo markers kwaye ugcwalisa kwitheyibhile. Umzekelo, umfanekiso uye 70 oneeseti eziyi-pixels ezinemibala e-orenji, omthubi kunye ezipinki ngebala. Ngamnye kubo uya kunikwa ixabiso efanayo - umzekelo, 8. Le datha iya egcinwe ngohlobo amaxesha 70 kunye amangenelo ezisibhozo. Inowuthi ingxolo kulo mfanekiso, ucinezelo kukuba ezikumgangatho ophezulu.

Enye into le fomathi indlela ngolu yokugcina ulwazi. Imiqolo bohlulwa babe ngamaqela, ukutshintsha odolo zazo ngaphakathi ifayile. Nangona umfanekiso ulayishiwe, ngokuthe ngcembe kuvela. Ngoko ke, lo gama GIFCA kuphela eboniseweyo ngokupheleleyo, kunokuthi kubonwe, kodwa isisombululo ephantsi.

abhalwe kuqala 1, 5, 9 kunye imigca phambili ngamathuba "4" ngendlela efanayo ukuba kuvela qalisa. Xa 25% ilandelwa, ungabona umfanekiso imfiliba. Ngaphezu koko kuvela imigca 3, 7, 11 kunye, umfanekiso uba amaxesha 2 ngakumbi. Ke kwixesha lolayisho enye series (2, 6, 10, ... 4, 8, 12 ...), kwaye ofumana uhlobo lokugqibela emfanekisweni. Le ndlela ukurekhodwa kwandisa kancinci ubukhulu SIFCO, kodwa ukwazi ukubona phambi kokuphela umxokozelo koko kanye leli phutha incinane.

Yintoni GIFCA "In Touch"?

imfanekiso, ayilayishwanga abasebenzisi BK - ezi imifanekiso ezihambayo ngohlobo GIF. Kuba abo sele ukwazi GIFCA kuba yintoni nomdla ukwazi ukubeka indlela kwinethiwekhi yoluntu.

Ukucola Luphiliso evela kwenye indawo, kufuneka nqakraza kwi ekunene iqhosha lemouse ekunene kwaye ufumane menu ekuvumela ukuba ukukhuphela idilesi (URL). Emva koko kufuneka uye kwindawo 'VKontakte "uze uncamathisele idilesi ye-ndawo apho ukuvela GIFCA (umzekelo, endle apho ubhale iposi okubhaliweyo phezu kodonga). Le nkqubo iza download ngokuzenzekelayo lo mfanekiso, uze uhlanganiso zisuswe. Cinezela Enter ukushicilela SIFCO.

SIFCO ukulayisha ezantsi ukusuka kwikhompyutha yakho, kufuneka zifakwe kwicandelo "Documents 'i (ulwahlulo ivulwa kwi Useto). Nqakraza "Faka uxwebhu", khetha izinga lokufikelela. Ukuze ukubeka SIFCO kumyalezo okanye ngeposi, kufuneka cinezela iqhosha "Namathelisa" kwaye ufumane ifayile.

imfanekiso, ibonwe ngabahlobo, unako zisindise. Ukuze wenze oku, kufuneka kubekho umfanekiso kunye "+", cofa kuyo, ekunene nqakraza kwaye ukhethe kwi menu into oyifunayo.

Yintoni SIFCO in VC? Le yindlela entle ukuhombisa iprofayile yakho, ukuvakalisa iimvakalelo, ukonwabisa wena kunye nabahlobo. Yongeza ephilayo imbalelwano okanye ababeseludongeni computer yakho okanye websites: Ngoku uyazi indlela yokuyenza!
