TIFF kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyiguqula kanjani i-TIFF ibe yi-PNG ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho TIFF futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomu le PNG. Ukungabi nalutho PNG (PNG, TIFF, BMP) wonke ama-pixel agcinwa; ukungabi nalutho PNG (JPG, WebP) ungalungisa umphumela womgangatho ngaphambi kokulayisha. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa. I-PNG isebenzisa ukucindezelwa kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele.

Yini ezoba nezinga le-layers kuhele lwami TIFF?

Zihlanganiswa, ngokuqhubekayo, kusithombe esifanayo esihlobene. Amamodali wokuxuba, ama-masks, ama-layers wokuhlela kanye nombhalo ohlelayo wonke axazululwa kumapixels aphesheya ngoba PNG ayikho isakhiwo esigcinayo. Gcina i TIFF njenge-master esebenza kahle futhi uthathe i PNG ngokuqinile njenge-export. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC efakwe ngaphakathi namaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingayo ukuphrinta nokugcinwa kwemisebenzi. I-PNG iyifomethi yesithombe esibi: isithombe esigcinwe njenge-PNG sivame ukuba likhulu izikhathi eziyisithupha kuya kweziyishumi kunesithombe esifanayo njenge-JPG noma i-WebP.

Ingabe umbala wami we-CMYK uzoqhubeka nokuguqulwa ku PNG?

Kuguqulwa ku sRGB, ngoba PNG ayikho indlela ye CMYK. Ukusetshenziswa kweskrini lokho kulungile. Uphrinta okuhweba akuyona - i-gamut shift ishintsha indlela imibala egcwele ikhiqizwa ngayo kuphrinta, ngakho-ke thumela umphrinta okuqala TIFF endaweni ye-PNG.

Ingabe TIFF kuya ku PNG ukuguqulwa kugcina ukubukeka okucacile?

Ukubukeka okucacile kuqhubeka uma PNG i-PNG, WebP, TIFF, GIF, noma SVG. Ukushintsha ku-JPG kwenza i-alpha channel ibe mhlophe. Uma ufuna ukubukeka okucacile esinqumweni, bheka ukubonakala okucacile okuqaphelayo PNG endaweni ye-PNG=JPG. I-PNG yakhiwa ngo-1996 njengento eshintshayo engekho emthethweni ye-GIF, futhi yashintsha ibe yifomethi yesithombe esingasebenzisi iphutha ye-web.

Yini mayelana ne-EXIF metadata uma uguqula TIFF kuya ku PNG?

Kuzo zonke izishintsho, ama-EXIF ama-camera afana nemodeli ye-camera nendawo ye-GPS afakwanga ku-PNG. Akukho sinqumo kule khasi sokugcina noma ukususa i-metadata, ngakho hlola imiphumela ngombonisi we-metadata uma kubaluleke.

Ingabe ngingakwazi ukushintsha amafayela amaningi TIFF abe PNG ngasikhathi sinye?

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

Yini isixazululo esizobe sikhona kuhele PNG?

Okuzenzakalelayo yi-1:1 — PNG yakho igcina ama-pixels alinganayo we-TIFF. Uma ufuna ukuguqula ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva kokuguqulwa, noma uyibeke nge /image-resize/ utility.

Ingabe amafayela ami TIFF afihlakele ngesikhathi sokuguqulwa?

Yebo. Amafayela TIFF alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi angeke ahlukaniswe. Ukulayishwa kanye nokuguqulwa kwe PNG kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukufinyelela kunqubomgomo egcwele.

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.

PNG

Amafayela e-PNG asekela ukucaca futhi asebenzisa ukucindezela okungenakulahlekelwa, okwenza afaneleke kakhulu kuma-graphics, ama-logo, kanye nezithombe-skrini.
