Ungasenza kanjani isithombe sosayizi omncane

Kulesi sihloko, sizobhekana nazo zombili izimvume zokwehla nosayizi wesithombe. Endleleni ngayinye, izinhlobo ezimbili zokuhlela zichazwa ngasikhathi sinye, ngakho-ke ufunde ngokuphelele imiyalo yohlelo olukhethiwe.

Indlela 1: I-Adobe PhotoShop

Umhleli we-Adobe Phrographic Graphic odumile ulungele ukunciphisa isithombe. Kunemisebenzi eminingana ohlelweni ngasikhathi sinye, eklanyelwe ukuguqula imvume nokucindezelwa ukuze into isibe isisindo esingaphansi manje. Kwesinye esihlokwana, izindlela ezintathu ezitholakalayo ongazisebenzisa ngewebhusayithi yethu kwiwebhusayithi yethu.

Indlela 2: Gimp

Kuyafaneleka ukusho i-analogue yamahhala ye-Photoshop - Gimp, enayo ngesethi efanayo yamathuluzi. Kuyo, ungashintsha ukulungiswa kwesifinyezo futhi unciphise ikhwalithi yawo ngokwenza usayizi wefayela lokugcina elingaphansi kokuqala.

1. Gijimisa uhlelo, vula imenyu yefayela bese ukhetha Vula. Esikhundleni salokho, ungasebenzisa ukhiye ojwayelekile oshisayo we-CTRL + O.



2. Kuzovela iwindi elisha esikrinini, lapho udinga ukuya khona endaweni yesithombe bese uqhafaza kuyo kabili ukuze uvule.



3. Ukuqala, cabanga ukuthi unganciphisa kanjani ukulungiswa kwesithombe esingeziwe. Ukuze wenze lokhu, shayela imenyu ethi "Image" bese uthola "usayizi wesithombe" lapho.



4. Efasiteleni elincane kufanele ushintshe ububanzi nokuphakama, kuya ngezidingo zomuntu. Uyacelwa ukuthi wazi ukuthi ushintsho oluzenzakalelayo lwengxenye lunikwe amandla. Ukucisha, udinga uchofoze esikhiye kwesokudla kwamasimu ngosayizi. Iwindi elifanayo liqukethe ibhulokhi "yekhwalithi" ngezinketho eziningi zokucubungula. Azisebenzi ekucindezelweni kwesithombe, ngoba leli algorithm lihloselwe ukunxephezela amaphikseli ngokukhulisa isixazululo sesithombe, esikhulisa ikhwalithi yaso.



5. Ukunciphisa into yesisindo ngesithombe kwenzeka nge-Compression ngesikhathi sokonga. Kulokhu, okokuqala udinga ukubiza "ukuthekelisa ngokuthi" ukusebenza kusuka kumenyu yefayela.



6. Nweba uhlobo lwe- "Khetha Ifayela (ngokwandisa".



7. Uma udinga ukuthola ifayela le-PNG FOMA, ungaguqula kukho. I-PNG inesisindo esingaphezu kwe-JPEG, kepha i-GIMP ikuvumela ukuthi ukhethe isilinganiso sokucindezela ngakho, ngaleyo ndlela ugcine ifomathi edingekayo, bese unciphisa isisindo salo.



8. Ngemuva kokukhetha i-PNG, ukuhlela kwamapharamitha angeziwe kuzovulwa. Veza isilinganiso sokucindezela ngokuya ngokuthi kufanele kube kanjani usayizi wefayela omusha. Ngeshwa, ungayihlola kuphela ngemuva kokuthekelisa. Izinto ezisele ngaphandle kokuthi "Gcina imvume" Kungcono ukuthi ungathinti.



9. Lapho ukonga ngefomethi ye-JPEG, ikhwalithi yesithombe ikhethiwe esikhundleni sokucindezelwa. Vele, umsebenzi "Sebenzisa izici zekhwalithi yesithombe sokuqala" kumele ukhubazeke, futhi i- "Ikhwalithi" Regulator ifakwe esimweni esamukelekayo kuwe.



10. Uma uvula amanye amapharamitha, umsebenzi ongaphansi wezobuchwepheshe uzovela ngenani elikhona lokulondolozwa kwesisindo esiphezulu. Ukuvuthwa kungcono ukushiya ngenani le-zero.

Indlela 3: udlame

Ake siqhubeke sisuka kubahleli esinemifanekiso siye ezinhlelweni ezikhethekile zenzelwe ukukhulisa amandla nekhwalithi yesithombe. Zilungile ngoba zikuvumela ukuthi uxhumane ngokushesha namapharamitha adingekayo futhi ujwayelane nomphumela ngaphambi kokonga. Isinqumo sokuqala sibizwa ngokuthi yiRway kanye nokusebenzisana kwenzeka kukho okufana nalokhu:

1. Cindezela inkinobho engenhla bese ulanda inguqulo yakamuva yobusoya kwikhompyutha yakho. Ngemuva kokuqala, iya kuthebhu ngegama lefomethi yefayela lapho isithombe esidingekayo sigcinwe khona ukuhlela, bese uqhafaza ku-Vula ukuvula isithombe.



2. Efasiteleni elivula elivelayo, thola into bese uqhafaza kuyo kabili.



3. Isiphakamiso sizokhulisa usayizi wesithombe ngokushesha, okudingeka uvuma.



4. Ku-Little "Resample" Window kufanele unciphise ukulungiswa kwesithombe, ukuhlela amasimu ebhlokini elisha.



5. Ngemuva kokuqinisekiswa kwezenzo, iwindi lohlelo oluphambili luzovuleka. Kuyo ubona isisindo sesithombe ngemuva kokwenza kahle. Lungisa i-slider "esezingeni eliphezulu uma ufuna ukuthola ifayela elicindezelwe ngokwengeziwe. Ngakwesobunxele kukhombisa ukubukeka kwasekuqaleni kwesithombe, nakwesokudla - ngemuva kokucutshungulwa.



6. Kuthebhu yeMetadata, ungasusa isithombe sesithombe, ngoba sisetshenziswa kakhulu, kepha kukhulisa usayizi wefayela.



7. Okulandelayo "ukulungiswa kwesithombe" ngeslayidi sokushintsha ukukhanya, umehluko kanye nokugembula kwesithombe. Akuthinti usayizi wento, kepha kusiza kuphela ukuthuthukisa ukubukeka kwesithombe.



8. Uma ufuna ukucindezela isithombe ngokuzenzakalela ngosayizi othile, sebenzisa inkinobho ethi "Compress to usayizi".



9. Ensimini entsha, faka umphumela oyifunayo kuma-kilobytes.



10. Lapho usuqede, chofoza inkinobho ethi "Gcina" ukuze ugcine ifayela elisha elivele livele noma liguqulwe ngosayizi wesithombe.



11. Cacisa igama layo bese ukhetha isandiso esifanele.

Indlela 4: I-Cesium

I-Cesium ihlinzeka umsebenzisi ngesethi yamathuluzi wokucindezela izithombe zombili ngokwekhwalithi nemvume. Ngokusobala, lolu hlelo lufana nelokuqala, kepha umsebenzi kulo luhlukile.

1. Ngemuva kokuqala, cindezela inkinobho ukuze uye efasiteleni elivulekile lefayela.



2. Ku- "Explorer", thola isithombe bese uqinisekisa ukwengeza kwawo kuhlelo.



3. I- "Compression parameters" block iveza isilayidi sokunciphisa ikhwalithi nohlu olunefomethi yokuguqula etholakalayo. Uma ungeze izithombe eziningana ngasikhathi sinye, yenza kusebenze "ukufaka isicelo sayo yonke" ipharamitha.



4. Beka ibhokisi eliseduze kwe- "Size Sikane" lapho udinga ukuhlela imvume yalo, hhayi usayizi wefayela uqobo. Emasimini "Wokubukelwa" kanye ne- "Height", setha amanani adingekayo kumaphikseli.



5. Ihlala kuphela ukucacisa ifolda yokukhipha izinto ezisetshenzisiwe.



6. Bheka futhi ukunemba kwamapharamitha akhethiwe bese uqhafaza "Yenza Ukucindezelwa".



7. Inqubo ithatha isikhathi esithile, okuncike kwinombolo nevolumu yamafayela angeziwe. Ensimini ethi "Ubukhulu obusha", ubona inani ama-kilobytes uma kungakufaneli, shintsha amapharamitha wekhwalithi futhi ucindezele futhi.

Indlela 5: I-Light Image Resizer

I-Light Light Resiziser isatshalaliswa ngemali, kepha isikhathi sayo sesilingo sekwanele ukunciphisa usayizi wezithombe eziningana. I-interface yenziwa ngesitayela esikahle futhi umsebenzi wayo yonke imisebenzi ucacile ngisho wabaqalayo, ngakho-ke akufanele kube nezinkinga zokucubungula isithombe.

1. Ngemuva kokusebenzisa ngempumelelo uhlelo, chofoza inkinobho ethi "Amafayela".



2. Ku- "Explorer", khetha isifinyezo ukunciphisa usayizi, ubuyela kwimenyu enkulu bese uqhafaza ku- "Phambili".



3. Ukucindezela usayizi wefayela, kusebenze ipharamitha "yobukhulu" bese usetha inombolo efiselekayo ye-kilobyte.



4. Cabanga ngeminye imisebenzi ewusizo lapho ukuhlela izithombe. Ku- "Usayizi" block, ungabeka isinqumo sokunqumela futhi ukhubaze isilinganiso soSIZO SOKUGCINA. Okulandelayo "igoli", lapho ungakhetha khona ukuthi uyokwakha amakhophi amafayela noma ungene esikhundleni sangempela kufolda efanayo. Ku- "enwetshiwe" Kunamathebhu amaningi ahlukile, kepha akayona eyokucindezela kwesithombe. Zisebenzise ezinye izinhloso - ngokwesibonelo, lapho ufuna ukwengeza izihlungi noma ushintshe ukuqondiswa kwesithombe.



5. Lapho usuqedile, chofoza u- "Run", ngaleyo ndlela uqhuba inqubo yokucubungula.



6. Uzokwaziswa ngokuphothulwa kokusebenza nesithombe futhi uthole imininingwane mayelana nevolumu yendawo egciniwe.
