JPG kuya BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Kusiza ukwazi ukuthi iphi ikhasi ngalinye likhona: I-JPG igcina i-8-bit RGB nge-DCT elahlekile nge-4:2:0 chroma subsampling ngokuzenzakalela, ngakho umbhalo obomvu oqinile kanye nama-edge anzima yizinto zokuqala zokuncibilikisa, ngenkathi I-BMP iyisici esibalulekile esingenakucindezelwa esingenakucindezelwa se-RGB nama-rowes anesihloko esincane, ngakho-ke ayilahleki futhi ikhulu — 10-20x ubukhulu besithombe esifanayo njenge-PNG. Layisha ihele lakho JPG futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomu le BMP kuphuma - kulabo abafuna ukulahlekelwa (PNG, TIFF, BMP, PSD) wonke ama-pixel agcinwa; kulabo abafuna ukulahlekelwa (JPG, WebP, GIF) ungalungisa umphumela wokhwalithi ngaphambi kokulanda.

Ingabe JPG kuya ku BMP 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 BMP.

Yini mayelana ne-EXIF metadata uma uguqula JPG kuya ku BMP?

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

Ingabe ngingakwazi ukushintsha amahele JPG ayizinkulungwane ku BMP 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 BMP?

Ukuziphatha okuzenzakalelayo yi 1:1 — i-BMP yakho iphuma isebenzisa i-pixel efana ne-JPG. 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 JPG afihlakele ngesikhathi sokuguqulwa?

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

Kungani ihele lami eliguqulwe BMP likhulu / lincane kunalokho engilindele?

Ubukhulu buthathwa yimibukiso emibini yokucindezela, hhayi yi-convertor. Khumbula ukuthi I-JPG igcina i-8-bit RGB nge-DCT elahlekile nge-4:2:0 chroma subsampling ngokuzenzakalela, ngakho umbhalo obomvu oqinile kanye nama-edge anzima yizinto zokuqala zokuncibilikisa, ngenkathi I-BMP iyisici esibalulekile esingenakucindezelwa esingenakucindezelwa se-RGB nama-rowes anesihloko esincane, ngakho-ke ayilahleki futhi ikhulu — 10-20x ubukhulu besithombe esifanayo njenge-PNG — ngakho-ke i-JPG ecindezelwe kakhulu ivame ukuGROWS uma iphinde ikhodwe ku BMP engalahleki, futhi i-JPG ecindezelwe kakhulu engalahleki ivame ukuncipha ngokuqinile ihamba ngenye indlela. Isithombe siqukethe izinto ezibalulekile: izithombe ne-flat line art zicindezela ngokuhlukile.

Ingabe ngisebenzisa ifayela eliguqulwe BMP ngebhizinisi?

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

JPG

Amafayela e-JPG asebenzisa ukucindezela okulahlekile okwenzelwe izithombe, okunikeza osayizi abancane bamafayela ngenkathi kugcinwa ikhwalithi yokubuka.
