Uma uzinikezela ekuthatheni izithombe noma umsebenzi ohlobene nezithombe, kuqinisekile ukuthi uyazi amafomethi afana neJPG, PNG, GIF ... Yizinto ezivame kakhulu osebenza ngazo. Kodwa kwesinye isikhathi uthola ukuthi uyakudinga guqula isithombe se-JPG sibe yi-PNG, Uyazi ukuthi ungakwenza kanjani?
Lapha sizokutshela ukuthi yiziphi izici zefomethi ngayinye yesithombe nokuthi ungayiguqula kanjani i-JPG ibe yi-PNG ngezindlela ezihlukile, noma ngabe ufuna ukukwenza ngohlelo, ngekhasi eliku-inthanethi noma kusuka kuselula yakho.
Yini isithombe seJPG
Ifomethi ye-JPG ingenye evame kakhulu embonini yedijithali, kodwa futhi iyona esiyisebenzisa kakhulu, kungaba lapho silanda isithombe kwi-Intanethi noma sisilayisha esisodwa kumanethiwekhi omphakathi. Ngokuzenzakalelayo, cishe zonke izinhlelo zigcina izithombe ngale ndlela, futhi uma uzenza ngekhamera yeselula, zinezandiso ze-JPG.
Ngokuqondile, i-JPG, eyaziwa nangokuthi i-JPEG, imele Amaqembu Ochwepheshe Bezithombe Ezihlangene. Leli igama elinikezwe "iqembu lochwepheshe" ukudala le fomethi. Futhi kwenzenjani? Kulungile icindezela izithombe, zombili lezo zenziwe ngokufiphaza nombala, zigcina ikhwalithi ephezulu (yize kukhona ukulahleka okungenziwa ngezifiso).
Ngakho-ke, ngokuya ngekhwalithi oyifunayo esithombeni, futhi ngokuya ngohlelo olisebenzisayo, unganquma ukuthi yikuphi ukulahleka kwedatha ozoba nakho, uma kunjalo. Lokhu kuthinta usayizi waleso sithombe, ngoba kusinda, kukhuphuka ikhwalithi yaso. Kepha kuzothatha isikhathi eside ukuyilanda, ukuyilayisha, ukuyishicilela, noma ukuyithumela.
Izinzuzo zokusebenzisa ifomethi ye-JPG ziningi, ikakhulukazi ngoba iyisandiso esisekelwa kakhulu yiziphequluli (futhi empeleni futhi ngamanethiwekhi okuxhumana nabantu njengoba kukhona amafomethi angaziboni). Ngaphezu kwalokho, ilula kakhulu ngenkathi igcina ikhwalithi, futhi kulula kakhulu ukuyibona lapho upheqa ngezithombe eziningi.
Yini isithombe se-PNG
Namuhla, iziphequluli zewebhu zinamandla okusekela amafomethi wesithombe amaningi. Okuvame kakhulu kuvame ukuba yi-JPG, GIF futhi yebo, ne-PNG. Noma kunjalo, le fomethi inezici ezithile ezihlukile kwezinye, futhi ezingaba nomthelela omuhle noma omubi kuye ngokuthi ufuna ukuyinikeza kanjani.
I-PNG yifomethi yesithombe engathulwa ngezindlela ezimbili ezihlukile:
- I-8-bit PNG. Ifana kakhulu ne-GIF, okusho ukuthi isithombe singakala kancane futhi sigcine izinga elithile lekhwalithi. Kepha awukwazi ukudala ukugqwayiza.
- I-24-bit PNG. Ihlobene nezici ze-JPG, okungukuthi, ingagcina izithombe ezinekhwalithi efanayo nobungako bemibala njengale enye ifomethi.
Manje, i-PNG ibonakala nge gcina isithombe usebenzisa ukuminyaniswa, kepha ngaphandle kokulahleka kwekhwalithi. Okusho ukuthi, uzoba nesithombe sekhwalithi ephezulu. Futhi, ngokungafani nalokho okwenzekayo nge-JPG, kuleli cala i-PNG iyakuvumela ukwenza izinto obala, okuthile okungenzeki ku-JPG (empeleni uma uzama ukuyigcina, ungqimba olusobala luyiguqula lube mhlophe). Kungakho kuyifomethi ekhethwe kakhulu ukugcina ama-logo, izithombe ezisezingeni eliphakeme kakhulu, noma uma zinama-gradients noma okusobala.
Ifomethi ye-PNG (okusho ukuthi "Portable Network Graphics") yathuthukiswa maphakathi no-1990s futhi yenziwa ngoba kwakudingeka ifomethi ezogwema izinkinga ze-GIF, kepha ngasikhathi sinye ingaba nazo zonke izinzuzo ze-JPEG kanye I-GIF.
Guqula isithombe se-JPG sibe yi-PNG
Manje njengoba wazi ifomethi ngayinye, yisikhathi sokukhuluma ngokuthi ungasiguqula kanjani isithombe se-JPG sibe yi-PNG, ngoba kunezinketho eziningi zokwenza lokho. Lapha sichaza eziningana zazo.
Izinhlelo zokuguqula isithombe se-JPG sibe yi-PNG
Inketho yokuqala onayo ukusebenzisa izinhlelo ozoba nazo ngokuqinisekile kukhompyutha yakho. Sikhuluma, ngokwesibonelo, nge-Paint, Photoshop, GIMP ... noma yimuphi umhleli wesithombe ngoba lokhu kuvame ukusekela amafomethi ahlukile.
Yini okufanele uyenze? Okulandelayo:
- Vula uhlelo ozolusebenzisa.
- Vula isithombe se-JPG ozosiguqulela kolunye uhlelo ohlelweni. Ungayihlela uma udinga noma usebenza nayo bese ulondoloze umphumela (noma uwulondoloze njengoba unjalo).
- Manje, sekuyisikhathi sokuyilondoloza. Kodwa-ke, esikhundleni sokushaya inkinobho ethi "Gcina", noma "Ifayela / Gcina", kufanele ushaye inketho ethi "Gcina njenge". Ngale ndlela, uhlelo luzohumusha ukuthi ufuna ukusindisa leso sithombe kepha ngefomethi ehlukile.
- Esikrinini se-Save As, izokunikeza uhlu lwamafomethi wesithombe ongasindisa kuwo isithombe. Ukuphela kokufanele ukwenze ukukhetha isandiso se-PNG ukuze ekugcineni usilondoloze futhi usigcine kukhompyutha yakho ngaleyo ndlela.
Amakhasi wamahhala we-inthanethi wokuguqula isithombe se-JPG sibe yi-PNG
Uma ungafuni ukusebenzisa uhlelo lwekhompyutha, kungaba ngoba ungenakho okufakiwe, noma ngoba udinga ukuthi lwenziwe ngokushesha (ikakhulukazi uma kunezithombe ezimbalwa ongaziguqula zisuke ku-JPG ziye ku-PNG, lapho-ke kungahle kuthakazelise ukusebenzisa amanye amakhasi e-web akunikeza le "sevisi."
Eqinisweni, eziningi zazo zikhululekile futhi okumele ukwenze ukulayisha izithombe futhi zizoshintsha ifomethi ngokuzenzakalelayo ukuze uphinde uzilande (ngamunye ngamunye noma kufayela le-zip) futhi ungaba nazo njengoba uzifuna.
Izibonelo zamakhasi wamahhala we-inthanethi wokuguqula isithombe se-JPG sibe yi-PNG yilezi ezilandelayo:

Kuthiwani uma ufuna ukuguqula isithombe se-JPG sibe yi-PNG? Ingabe kunesidingo sokudlulisa isithombe kwikhompyutha yakho kuqala ukuze usebenze naso futhi usiguqule? Noma ungakwenza kusuka kuselula efanayo?
Yebo, ungakwenza kanjalo. Ukwenza lokhu, unezinketho eziningana:
- Ungakwenza ngezinhlelo zokusebenza, njenge-Photo Converter; Isithombe nesithombe esiguqulayo jpg pdf eps psd, png, bmp…; Isiguquli sesithombe, isithombe ku-JPG / PNG, PNG Magic ...
- Enye inketho ngokusebenzisa isiphequluli, sisebenzisa amakhasi afana nalawa esesishilo ngaphambili, ukuthi cishe zonke zisebenza ngefomethi yeselula.
