Tom qab ua tiav txhua txoj haujlwm ntawm daim duab (daim duab), koj yuav tsum khaws nws rau koj lub hard drive, xaiv qhov chaw, hom ntawv thiab muab qee lub npe.
Niaj hnub no peb yuav tham txog yuav ua li cas thiaj li txuag tau txoj haujlwm tiav hauv Photoshop.
Thawj qhov koj yuav tsum txiav txim siab ua ntej pib cov txheej txheem cawm yog cov qauv.
Tsuas muaj peb hom tawm tswv yim nkaus xwb. Nws yog Jpeg, PNG thiab GIF.

Ib qho tshwj xeeb ntawm hom ntawv yog lwm zaus koj qhib thiab kho qhov hu ua JPEG artifactstshwm sim los ntawm kev poob ntawm qee qhov ntawm cov pixels nyob hauv nruab nrab cov duab ntxoo.
Nws ua raws tias hom ntawv no haum rau cov duab uas yuav siv "zoo li", uas yog, lawv yuav tsis tau kho los ntawm koj.
Tom ntej no tuaj lub hom PNGCov. Cov hom ntawv no tso cai rau koj kom txuag tau daim duab yam tsis muaj keeb kwm yav dhau los hauv Photoshop. Daim duab kuj tseem tuaj yeem muaj cov keeb kwm yav dhau los translucent lossis cov khoom siv. Lwm cov qauv pob tshab tsis txhawb nqa.
Tsis zoo li hom qub dhau los, PNG thaum rov tsim kho (siv hauv lwm cov haujlwm) tsis poob zoo (yuav luag).
Tus sawv cev hom tshiab tshaj plaws niaj hnub no yog GIFCov. Hais txog qhov tsis zoo, qhov no yog hom tsis zoo, raws li nws muaj qhov txwv ntawm tus naj npawb ntawm cov xim.
Txawm li cas los, GIF tso cai rau koj kom txuag tau cov animation hauv Photoshop CS6 nyob rau hauv ib qho ntawv, uas yog, ib qho ntaub ntawv yuav muaj tag nrho cov ntawv kaw tseg ntawm cov animation. Piv txwv li, thaum txuag cov animations rau PNG, txhua daim ntawv sau tau ua ib daim ntawv cais.
Cia peb xyaum me me.
Txhawm rau hu qhov txuag nqi, mus rau cov ntawv qhia zaub mov Cov ntaub ntawv thiab nrhiav cov khoom Txuag Raws Li, los yog siv tus yuam sij kub CTRL + Hloov + S.
Tom ntej no, nyob rau hauv lub qhov rai uas qhib, xaiv qhov chaw nyob kom txuag, lub npe thiab cov hom ntaub ntawv.
Nov yog tus txheej txheem ua haujlwm thoob ntiaj teb rau txhua hom tshwj tsis yog GIF.

Tom qab nias lub khawm Txuag lub chaw teeb tsa ntawv tshwm sim.
Lub substrate
Yog, peb twb paub cov hom ntawv Jpeg tsis txhawb kev ua kom pom tseeb, yog li ntawd, thaum txuag cov khoom ntawm lub pob tshab, Photoshop qhia kom hloov cov pob tshab nrog qee xim. Los ntawm lub neej ntawd nws yog dawb.
Duab Xaiv
Daim duab zoo tau teeb tsa ntawm no.
Ntau hom ntawv
Basic (Txuj) qhia cov duab ntawm lub vijtsam kab los ntawm kab, uas yog, hauv txoj kev ib txwm.
Yooj yim optimized siv Huffman algorithm rau kev nyem. Dab tsi yog qhov no, Kuv yuav tsis piav qhia, saib koj tus kheej hauv net, qhov no tsis siv rau cov lus qhia. Kuv tsuas tuaj yeem hais tias hauv peb qhov no yuav ua rau peb txo me me ntawm cov ntawv loj, uas tsis cuam tshuam rau hnub no.
Kev vam meej Tso cai rau koj los txhim kho cov duab zoo ib kauj ruam dhau los thaum nws rub tawm rau lub vev xaib.
Hauv kev xyaum, thawj hom thib peb thiab peb feem ntau siv. Yog tias nws tsis meej meej vim li cas tag nrho chav ua noj no xav tau, xaiv Basic ("txuj").
Txuag hauv PNG
Thaum txuag rau hom ntawv no, lub chaw teeb tsa kuj pom.
Ntsuas Siv
Qhov kev teeb tsa no tso cai rau koj los zaws qhov kawg nkaus PNG cov ntaub ntawv tsis tau poob zoo. Lub screenshot yog teeb tsa rau kev cog lus.
Hauv cov duab hauv qab no koj tuaj yeem pom cov degree ntawm compression. Thawj lub vijtsam nrog daim duab nrawm, qhov thib ob nrog ib qho tsis pom.
Raws li koj tuaj yeem pom, qhov sib txawv yog qhov tseem ceeb, yog li nws ua rau nkag siab kom tso daw nyob rau hauv "Tsawg me / qeeb tshaj".
Interlaced
Kev Los Ua Poj Nrauj "Tsis xaiv" tso cai rau koj kom pom cov ntaub ntawv ntawm lub vev xaib tsuas yog tom qab nws tau thawm tag nrho, thiab Interlaced nthuav qhia tus duab nrog kev maj mam txhim kho hauv qhov ua tau zoo.
Kuv siv cov nqis, raws li hauv thawj lub screenshot.
Txuag tau GIF
Txhawm rau khaws cov ntaub ntawv (cov tsiaj ntawv) nyob rau hauv hom GIF tsim nyog hauv cov ntawv qhia zaub mov Cov ntaub ntawv xaiv cov khoom Tseg rau Hauv Web.
