Imifanekiso Raster kunye nomsebenzi kunye nabo

Xa sisebenza kunye nemizobo ezikumila kumacala mabini, kubaluleke kakhulu ukuqonda iziseko isakhiwo kunye nemigaqo apho uya kutshintshwa, ilizwi, ukumela, njengoko kubonakala nge computer. Yeentlobo ezimbini eziphambili imifanekiso - kumda wesangqa kunye yeraster -each ifumana isicelo yayo kwindawo ethile, kwaye kananjalo nezinto zalo eziluncedo.

Units apho ibitmaps ezi pixels. Ezi izikwere encinane monitor, eziqulathe kunye nokudlulisela ulwazi umbala. Kunye ibitmaps zabo uncedo elisongiweyo ngathi puzzle, kwaye waqonda xa iyonke. Umgangatho monitor ukubonisa ezi imifanekiso kuxhomekeka kwinani pixels-intshi. Ngokomthetho yonke iikhompyutha mihla enziwa enesisombululo of pixels 72 okanye 96 nge-intshi (ixabiso kuyahlukana nedlela parameters yeskrini).

imifanekiso Raster ingagcinwa kwakhona ngokukhawuleza ahluka ukusuka kumda wesangqa abasetyenzisiweyo ngokukhangela kwi ngobukhulu. Le fomati oluqhelekilyo eyi - a gif, .bmp, .png, jpeg, .psd kunye nabanye.

imifanekiso Raster zifunyanwa njengokwenza ifayile kwi Adobe Photoshop usebenzisa izixhobo ezisisiseko, ngokunjalo ukukrwaqula nawaphi amaxwebhu. Ukongezelela, onke iifoto ningabaleli hlobo yemizobo emacala-mabini. Ngaloo ndlela, ngaphandle kokutshintsha kwifomathi ezi ntlobo iifayile kule nkqubo, unako ukuthintela ukuphulukana umgangatho uhlaba imibala. Kwaye print imifanekiso usebenzisa iprinta, njengoko umfanekiso bitmap.

Translation yeraster umfanekiso ibe kumda wesangqa noko ilula kwaye kufuna kuphela umhleli yemizobo exhasa zombini iindidi zemifanekiso. Kulo mzekelo, xa ukugcina umfanekiso sibonisa nje format yemizobo kumda wesangqa. Noko ke, le ndlela ayisoloko ukunika iziphumo ezilungileyo. Kubalulekile kakhulu ukuba ngokutsha ngesandla umfanekiso bitmap ibe kumda wesangqa, kodwa ke ifuna ubuchule okulungileyo ekusebenzeni kumhleli yemizobo kumda wesangqa.

Ngoko ke, makhe abethelele iingongoma eziphambili kumfanekiso ye bitmap kwikhusi - igridi pixel, umgangatho leyo ixhomekeke isisombululo kunye kumphathi wakho. yemizobo ezinjalo kalula ibe ngenye indlela. Phezu sihlolisisa ezi iziphaluka ezi ngokohlobo imifanekiso Somzobo onamacala amaninzi uziziqwempu line ezo imida pixels.

imifanekiso Raster ke, ngaphandle kwamathandabuzo, kuneengxaki kunokwenzeka, nto leyo nayo angena kubethwa ngoyaba. Ngokungafaniyo yemizobo wesangqa, loo imifanekiso imida ukwanda kunye nezinye iinguqu ezinkulu. Ekubeni ukwanda okubonakalayo isikali a bitmap, kusenokwenzeka ukuba ulahlekelwe yimali. Ngoko ke, ukugcinwa we pixel imifanekiso yobukhulu enkulu iquka, ngokulandelelana, kunye oluninzi kwinkumbulo yekhomputha. Ukongeza, ezi yemizobo yeraster phantse akayixhasi iipropati elubala. imifanekiso kuphela gif kwaye png afakwa kulo msebenzi, ngoko ke kufuneka umgangatho kwinqanaba eliphezulu.

format Raster afanelekile kakhulu abo baxhasa ekudaleni imifanekiso kunye izithunzi entsonkothileyo zinjalo, kunye nezinye iziphumo-ntathu kunye noburhabaxa. Kakade ke, abafoti ukusingatha lowo wakho imifanekiso Photoshop, ibonisa kuphela uhlobo lwe bitmap graphic.
