Ukusebenzisa Izithombe ezigqamile kwiWebhu nakuPrinta
Ngakho-ke, usanda kususa isizinda esivela esithombeni futhi manje ufuna ukusebenzisa isithombe esicacile kwenye indawo. Wenzani? Impendulo ayilula - kuxhomeke lapho uhamba nayo. Ngakho ake sibheke izinketho zakho.
Kusukela ku-Photoshop (izinguqulo ngaphambi kwe-CS4)
Okokuqala, uma usebenza ku-Photoshop futhi uzophrinta noma iWebhu, hlola i-Export Transparent Image Image Wizard etholakala ngaphansi kwemenyu yosizo. Izokucela uchungechunge lwemibuzo futhi ithumele isithombe ngesakhiwo esifanele. Le nketho isusiwe ku-Photoshop CS4.
Kunezindlela ezimbili kuphela zokubonisa isithombe sedijithali. Isithombe sizovela esibukweni njenge-smartphone, ithebhulethi noma ideskithophu (noma ngaphezulu) ukubonisa noma ukuphrinta. Kanjalo isinqumo sehlela ukufometha ifomethi.
Isithombe siya kusikrini.
Unezinketho ezintathu lapha: GIF, PNG, noma "uzifake nge-JPEG."
- I-GIF - i-GIF iyifomethi yangempela ngokusekelwa okubonakalayo kweWebhu. Inkinga nge-GIF yukuthi kunciphisa i-palette yambala ngokungabi ngaphezu kwemibala engu-256, okwenza ukushintsha kombala, ukuthunyelwa kweposi noma ukukhishwa kwemibala, nokuphazamiseka emifanekisweni emibala ephezulu njengezithombe. Uma ubukhulu bomzimba bomfanekiso buncane njengesikwele esingu-1 intshi noma uzobe uthumela isithombe kwisayithi yezokuxhumana, njenge-Twitter, bese kuthi i-GIF ibheke enye into engezansi ku-GIF ukuthi isekela ngokucacile oku-1-bit. Lokho kusho ukuthi i-pixel ngayinye emfanekisweni wakho iyabonakala ngokucacile noma ayikho into ecacile. Lokhu kusho amasu afanayo afana nokulahla izithunzi nama-vignettes.
- I-PNG - PNG ifomethi eyakhiwe ukuze inqobe ukulinganiselwa okuningi kwe-GIF. Isekela ukukhanya okuphezulu nombala obala usebenzisa iziteshi ze-alpha . Nakuba i- PNG isilokhu iseduze okwesikhashana manje, kuthathe isikhathi eside ukufeza ukwemukelwa okubanzi ngenxa yokuntuleka kokusekelwa kwesiphequluli eminyakeni yakhe yokuqala. Kodwa amafayela we-PNG evulekile asekelwe kusukela ku-IE7, futhi asekelwa kuzo zonke iziphequluli zewebhu ezidumile namhlanje, ngakho-ke kuphephile ukusebenzisa i-PNG kulezi zinsuku ngaphandle kokuthi wazi ukuthi ingxenye enkulu yezilaleli zakho isebenzisa i-hardware ne-software enkulu kakhulu. Izithombe ze-PNG nazo zivame ukubonwa kumadivayisi eselula.
- Qaphela ukuthi uma ufuna ukugcina obala ngokugcwele ngaphandle kwe-halo ephikisanayo, udinga ukulondoloza ifayela lakho le-PNG njengo-PNG-24 hhayi iPNG-8. I-PNG-8 iyasiza ekunciphiseni usayizi wefayela wamafayela we-PNG uma ungadingi ukukhanya, kepha unemikhawulo efanayo yembala ye-palette njengamafayela we-GIF .
- Enye ifomethi ejwayelekile ye-PNG i-PNG-32.Lona akuwona umfanekiso we-32-bit onamabhiliyoni emibala. Lesi yisithombe esimaphakathi esingu-24-bit nesiteshi esingeziwe esingu-8-bit se-greyscale esisetshenziselwa ukubonakala.Kubhokisi lebhokisi le-Photoshop's Export As ..., uma uchofoza ibhokisi lokuhlola le-Transparency udala isithombe se-PNG-32.
- Ukuguqulwa kobugebengu nge-JPEG - Lo msebenzi ozungeze lapho izindawo zesithombe ofuna ukuzenza zivele zigcwele umbala ohlukile wesizinda noma ukuthungwa njengekhasi lewebhu bazobekwa kuzo. Lokhu kusebenza kahle uma ubeka isithombe kusizinda esinembala esiqinile, noma isizinda esincane esincane esibhalwe phansi lapho ukulungiswa kungeke kube yinkinga.
- Leyo yindlela eyodwa yokwenza. Enye ukusebenzisa ukusebenzisa ithuluzi lokukhethwa ukuze ubambe umbala oqinile noma ukusebenzisa Umyalo wokugcwalisa ukugcwalisa ukukhethwa ngombala oqinile.
- Okuningi ku-JPEG
Isithombe senza isicelo sokuhlela ikhasi njenge-InDesign, i-QuarkXpress noma i-PageMaker.
Unezinketho ezintathu lapha: Ifomethi ye-PSD yemvelo ye-Adobe, imigudu efakiwe, noma iziteshi ze-alpha.
- Ifomethi ye-PSD ye-Adobe yemvelo - I-PSD igcina ukukhanya phakathi kwezicelo ze-Adobe, ngakho-ke uma usebenza ngokuphelele ku-Adobe izicelo, sebenzisa ifomethi ye-PSP yangempela ye-Photoshop ngokubonakala.
- Imizila Ehlanganisiwe (EPS) - Izithombe ze-EPS zisekela ukusetshenziswa kwezindlela zokuchofoza ezihlanganisiwe futhi izicelo eziningi zokushicilela ideskithophu zizokwamukela ifomethi ye-EPS . Uma izindlela ezihlanganisiwe zisetshenziselwa ukukhanya, into ehlukanisiwe ingaba nemiphetho enzima kuphela. Akukho okubonakalayo okusobala.
- Okuningi ku-Paths | Okuningi ngokuKhuqa imigudu
- Iziteshi ze-Alpha (TIFF) - Iziteshi ze-Alpha ziyi-masm bitmap ezichaza obala emathunzini wegrey. Uma lisetshenziselwa izinhlelo zokusebenza zokuhlelwa kwekhasi, ifomethi ye-TIFF ikhethwa izithombe ezine- transparency yesiteshi .
- Okuningi kwiziteshi ze-Alpha | Okuningi ku-Masks
Amathrekhi afakiwe ngokumelene ne-Alpha Iziteshi - Imininingwane yokudala nokusebenzisa izindlela ezifakiwe kanye neziteshi ze-alpha zingatholakala kule ngxenye emihlanu yokufundisa kusuka ku-About Desktop Publishing.
