Unogona kudhonza nzvimbo yaunoda kubva pakutanga, kana kunyora zvakajeka pixel coordinates kana iwe uchiziva.

Ndinogona here kuchera kunzvimbo ine kureba kwechifananidzo?

Kana iwe uchida, kushandura kune PNG yekutanga kazhinji inokwana pachayo - BMP inowanzo kuve makumi maviri nemakumi maviri emakore emhando yeiyo imwecheteyo vhidhiyo sePNG.

I Kukasira BMP ichadzikisa mhando ye BMP images yangu?

Chirongwa chealpha chinoramba chichishanda?

Yeah. PNG neTIFF dzinotora 8-bit alpha channel uye inochengetwa kubva pakutanga kusvika pakupera. Inogona kuiswa chete kana iwe uchida kushandisa fomati isina alpha, saka mapikicha anoratidzika zvakanaka anoiswa pamavara emavara.
