tshiab tseem ceeb tsev qiv ntawv tso tawm , tsim los ua haujlwm zoo ntawm kev tswj hwm thaj chaw ntawm pixels, piv txwv li, rau kev sib txuas cov duab thiab ntau hom kev hloov pauv. Lub tsev qiv ntawv yog siv rau cov duab qis qis hauv ntau qhov chaw qhib, suav nrog X.Org, Cairo, Firefox thiab Wayland / Weston. Hauv Wayland / Weston, raws li Pixman, kev ua haujlwm ntawm backends rau software rendering yog npaj. Tus lej yog sau hauv C thiab nyob rau hauv MIT daim ntawv tso cai.
Kev tso tawm tshiab ntxiv kev txhawb nqa yooj yim nyob rau hauv "dav" hom, ntxiv ib qho kev txiav txim dithering lim nrog xiav suab nrov thiab demo cov ntaub ntawv nrog piv txwv ntawm kev siv dithering. Cov ntawv tsim ua raws li Meson cov cuab yeej tau hloov kho tshiab, lub peev xwm los tsim Pixman hauv daim ntawv ntawm lub tsev qiv ntawv zoo li qub tau ntxiv, thiab cov kev kuaj xyuas tsis ua haujlwm tau ntxiv. Txhim kho tsim rau lub Windows platform siv MSVC compiler. Ntxiv kev txhawb nqa rau cov lus qhia txuas ntxiv (X86_MMX_EXTENSIONS) ntawm Suav Hygon Dhyana CPUs, ua raws li AMD thev naus laus zis.
Kev them nyiaj yug rau ARMv3 SIMD cov lus qhia suav nrog rau Nintendo 6DS consoles, thiab Neon SIMD cov lus qhia rau PS Vita. Kev hloov pauv tau ua los ntawm kev siv MD5 / SHA1 hashes rau SHA256 / SHA512.
