Indlela yokujika JPEG

1 Layisha phezulu i JPEG images ofuna ukuyibona.

2 Khetha umgca ongagqibekanga - othe tyaba unika umfanekiso we-mirror, othe nkqo ubonisa umbono ojikelezayo phantsi.

3 Sebenzisa ujikelezo, emva koko khangela naliphi na inqaku, ilogo okanye inani kwimboniselo yangaphambili, kuba ezi zibonisa ngaphaya kunye nezinye zonke izinto.

4 Layisha ezantsi ifayili ejikelezayo JPEG.

Jikelezisa JPEG Imibuzo ebuzwa rhoqo

Ndingayijika iifayili ezininzi ngaxeshanye?

Ewe. I-axis efanayo isetyenziswe kwifayile nganye kwiqela, eyenza ukuba ulungise isiqulathi seefayili esipheleleyo semifanekiso ejikelezayo ethathwe kwindlela enye endaweni yenye ngexesha.

I-Jikelezisa JPEG ibonisa njani ifayili?

Ngokucacileyo, i-mirror ethe tyaba okanye ethe nkqo yi-DCT eguqulweyo engalahlekiyo, ngoko ke ifayile ibhalwe kwakhona ngaphandle kokucoda kwaye iphinde ikhode umfanekiso wonke - i-output ifana ne-pixel efana ne-mirror ebhaliweyo. Ukhetha umgca ohamba phambili - othe tyaba uvelisa umfanekiso we mirror, othe nkqo uvelisa umbono ojikelezayo - kwaye ifayile yonke iguqulwa kuyo.

Nantoni na ekhethekileyo kwi JPEG ekufuneka ikwazi?

Ewe — i.jpeg ne.jpg izilungiso ziyi-bitstream efanayo, ngoko akukho nto apha esebenza ngokuhlukileyo kune-.jpg — kuphela igama lefayili litshintsha. Kufuneka ulinde ixesha ngaphambi kokuba ujikelezise into engayi kuyenza kwakhona ngokulula.

Ndiza kuzama nini ukujika imifanekiso?

Ukulungisa uvavanyo okanye ukuthatha i-webcam eyaphuma ifana, yenza isibini esilinganayo esisuka kwi-assets enye, okanye uthelekiso lokuhamba kwento ejonge ubeko. Ukuba imixholo iqulethe umbhalo, ilogos okanye amanani, khangela isiphumo - ezifana nazo.

Yintoni endinokuyilayisha kwi Jikelezisa JPEG?

Ingaba kukho umda wobungakanani befayili kwi Jikelezisa JPEG?

Ewe: i-akhawunti ekhululekileyo iqhubekeka imifanekiso ukuya kwi-5 MB nganye, equka ngokucacileyo yonke ikhamera ye-JPG kunye nefowuni yomfanekiso; umsebenzi ukwenziwa yi-libjpeg-turbo ne-libwebp, iilayibrari ezifanayo umhleli we-desktop uqhagamshelana nazo. Iifayili ezinkulu zizinto ezi-1 ezimfutshane ezikhululekileyo eziza kukuthintela, kwaye umda yifayili nganye kunokuba yiqela ngalinye.

Ingaba i Jikelezisa JPEG iya kunyusa ubunjani be JPEG images yam?

Umthombo olahlwayo sele uyimpumelelo yendlela enye yokugqitha, kwaye nayiphi na imisebenzi efuna ukubuyisela ikhowudi idibanisa enye. Xa umsebenzi ungakwenziwa ngaphandle kokucofa i-pixel data siyenza endaweni, kwaye apho ayikwazi khona ukhetha umgangatho wezinto eziluncedo ngokwakho kunokuba ufumana okumiselweyo okumiselweyo.

Ndingaqhuba i Jikelezisa JPEG kwi JPEG images ezininzi ngaxeshanye?

Ewe. Nciphisa iqela lonke kwindawo yolayisho phezulu kwaye ziphole ngokuthe ngqo ngemimiselo efana nayo - le yisizathu esiphambili sokwenza oku kumkhangeli zincwadi kunokuba yifayile enye ngexesha kumhleli. Iiakhawunti ezikhululekileyo ziqhuba ifayile enye kwiqela; i pass iphakamisa loo nto.

Kutheni i EPUB inxuwa liququzelela Jikelezisa JPEG?

EPUB.to ibekwe phantsi kwefomati evulekileyo yencwadi ye-e-XHTML kwi zip, ephinda ijikeleze ngoyilo, kwaye ifundeka kwizixhobo zekhompyutha akukho mntu ucinga malunga nobeko. Incwadi yizip egcweleyo yemarkup, imifanekiso kunye nefonti, ngoko ke phantse yonke imisebenzi abantu bezisa kwiwebhusayithi ye-eBook isebenza kwelinye lawona zinto. Jikelezisa JPEG iqhuba kwi-upload efanayo ne-akhawunti efanayo njenge-conversions kuba apho ifuneka khona.

Ndiza kwenza ntoni ngeziphumo xa i Jikelezisa JPEG igqityiwe?

Umguquli kule ndawo uhambisa iincwadi phakathi kwe-EPUB, MOBI, AZW3, PDF ne DOCX, ngoko ke igama liphela kwisixhobo esibonakalayo esiza kufunda. Ukwenza oko emva Jikelezisa JPEG kuthetha ukuba uguqulelo luzakwenziwa ukusuka kuhlobo olungqine ngalo, hayi ukusuka kulowo wawusazilungisa.

Ingaba Jikelezisa JPEG apha isixhobo esifanayo esisebenza kumasayithi afana nalowo?

Iinjini zinikezelwa - isixhobo esifanayo, abasebenzi abafanayo, amaqondo afanayo. Oku EPUB site idibanisa kukubona kwi reflow: yeyiphi yemisebenzi le ncwadi ephindayo ixhasa ngokuqinisekileyo, kwaye yeyiphi kuphela eyenza ingqondo kwi media ethe nkqo- ubeko ngaphakathi kwayo. Iqala kwakhona kwi nto enye malunga nefomati le site ibizwa emva: incwadi yi zip ye XHTML ene manifest, ngoko umbhalo ubiza ngaphantsi kwento kwaye ugqibo ngalunye olubalulekileyo lumalunga nomfanekiso ofakwe ngaphakathi kunye nefonti ye subsets.

Ndifuna i-akhawunti, kwaye ngaba kukho into egcinwa?

Akukho akhawunti, kwaye akukho nto igcinwayo: ulayisho lususwa kubasebenzi emva kokuba umsebenzi ugqibile, akukho nto ifundwayo kwaye akukho nto iqulathe isiqulathi seefayili. Iiakhawunti ezikhululekileyo zikhona kwimbali kunye nobungakanani beqela, hayi kwi access.
