BMP kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Kusiza ukwazi ukuthi iphi ikhasi ngalinye likhona: I-BMP iyisici esibalulekile esingenakucindezelwa esingenakucindezelwa se-RGB nama-rowes anesihloko esincane, ngakho-ke ayilahleki futhi ikhulu — 10-20x ubukhulu besithombe esifanayo njenge-PNG, ngenkathi I-PNG i-DEFLATE engalahlekelwanga nge-8-bit alfa channel ephelele ne-16-bit ububanzi obukhethwayo, ngakho-ke ayikwazi ukuncipha uma igcinwa futhi kodwa itholakale enkulu kuma-contents wezithombe. Layisha ihele lakho BMP futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomu le PNG kuphuma - kulabo abafuna ukulahlekelwa (PNG, TIFF, BMP, PSD) wonke ama-pixel agcinwa; kulabo abafuna ukulahlekelwa (JPG, WebP, GIF) ungalungisa umphumela wokhwalithi ngaphambi kokulanda.

Ingabe BMP kuya ku PNG ukuguqulwa kugcina ukubukeka okucacile?

Ukubukeka okucacile kuqhubeka uma udlula ku-PNG, WebP, TIFF, GIF, ICO, PSD noma SVG. Ukushintsha ku-JPG / JPEG / JFIF kuhlambulula i-alpha channel ebheke emuva okumhlophe — uma ufuna ukubukeka okucacile, bheka ifomu elikwaziyo ukubukeka okucacile endaweni ye PNG.

Yini mayelana ne-EXIF metadata uma uguqula BMP 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 amahele BMP ayizinkulungwane ku 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 kanye nezici ezizobe zikhona kuhele PNG?

Ukuziphatha okuzenzakalelayo yi 1:1 — i-PNG yakho iphuma isebenzisa i-pixel efana ne-BMP. I-ICO iphuma ingekho (ikhiqiza isixazululo esiningi se-stack: 16/32/48/64/128/256). Uma ufuna ukuguqula ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize/ ngemuva kokuguqulwa.

Ingabe amafayela ami BMP afihlakele ngesikhathi sokuguqulwa?

Yebo. Amafayela BMP 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/ ukuphoqa okuphelele.

Kungani ihele lami eliguqulwe PNG likhulu / lincane kunalokho engilindele?

Ubukhulu buthathwa yimibukiso emibini yokucindezela, hhayi yi-convertor. Khumbula ukuthi I-BMP iyisici esibalulekile esingenakucindezelwa esingenakucindezelwa se-RGB nama-rowes anesihloko esincane, ngakho-ke ayilahleki futhi ikhulu — 10-20x ubukhulu besithombe esifanayo njenge-PNG, ngenkathi I-PNG i-DEFLATE engalahlekelwanga nge-8-bit alfa channel ephelele ne-16-bit ububanzi obukhethwayo, ngakho-ke ayikwazi ukuncipha uma igcinwa futhi kodwa itholakale enkulu kuma-contents wezithombe — ngakho-ke i-BMP ecindezelwe kakhulu ivame ukuGROWS uma iphinde ikhodwe ku PNG engalahleki, futhi i-BMP ecindezelwe kakhulu engalahleki ivame ukuncipha ngokuqinile ihamba ngenye indlela. Isithombe siqukethe izinto ezibalulekile: izithombe ne-flat line art zicindezela ngokuhlukile.

Ingabe ngisebenzisa ifayela eliguqulwe PNG ngebhizinisi?

Yebo. Ukuguquka kuyisimo sokuguqulwa - ilungelo lokushicilela kusithombe sihlala kuwe (noma ophethe isithombe kumthombo BMP). Sifaka i-watermark, i-metadata stamp, futhi sicela i-license ngaphezulu kwe-output.

BMP

Amafayela e-BMP agcina izithombe ngefomethi ye-bitmap engacindezelwanga, okuholela osayizi bamafayela abakhulu kodwa ikhwalithi ephelele.

PNG

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