JPG ukuba ICO Imibuzo Ebuzwa Rhoqo Ngokuguqula

Kwifomati engalahlikiyo ICO (PNG, TIFF, BMP) yonke i-pixel igcinwa; kwifomati elahlayo ICO (JPG, WebP) ungalungisa umgangatho phambi kokukhuphela. I-JPG ilahlekile: umfanekiso uguqulwa nge-DCT, i-quantized, kunye ne-entropiya-ekhowudiweyo, ngeqhosha lomgangatho elilawula ukuba kuphi okuninzi okulahlekileyo. I-ICO enye igcina iziboniso ezininzi ze icon efanayo kubungakanani obuhlukileyo - 16x16 ukuya kwi-256x256 - ukuze i-OS ikhethe enye eqaqambileyo.

Yintoni ubungakanani obumele i ICO iqulethe?

Qhubeka 16x16, 32x32, 48x48 kunye ne 256x256 kwaye ucofe zonke iwindows ezikwimeko-bume kunye namacebo okukhangela afuna. I ICO epheleleyo igcina zonke, ngoko inkqubo yokusebenza ikhetha uthelekiso olufutshane endaweni yokubuyisela ubungakanani obunye ezantsi kwaye iyenze ibe mnyama.

Phumeza /susa indawo yangasemva/ emva koko ukucima isiqalo — ngoko i-alpha isiqhagamshelanisi ICO ibonelela ngento yokugcinwa. I-ICO ivumela ifayili enye ukuba isebenze ibar yomsebenzi, uluhlu lwefayile, isinqumlisi se-desktop kunye ne-tab yomkhangeli zincwadi ngaphandle kokuba nanye yazo ijonge iphinde ithathe ithamsanqa.

Hayi. Ii-artefacts zokucinezela eziphekwe kwi JPG zii-pixels zedata eziqhelekileyo ngoku, kwaye ICO igcina kakuhle kunokuba isuse. Ifayile ihlala ikhula, ngamanye amaxesha ikhula amaxesha amaninzi. Kubalulekile ukwenza phambi kohlela, kuba utshintsho oluthe kratya aluyi kunyusa udidi lwesibini lolahleko phezulu.
