It is recommended that android can choose this method to deal with the shortcomings of ETC1 without alpha channel. Memory consumption 4bppД®TC1_A and ETC1_RGB are used in combination to provide alpha channel for ETC1_RGB to achieve transparency. This is also the point that ETC1 has been complained about, so there was an ETC2 later. Memory consumption 4bppД®TC1_RGB consumes very little memory, loading speed is faster than RGBA8888, rendering speed is faster, and the effect is relatively good, but there is no alpha channel. It is strongly recommended that ios use this format. PVRTCI_4BPP_RGBA effect of PVRTCI_4BPP_RGBA is worse than RGBA8888, but the memory consumption is very small, the loading speed is fast, and the rendering speed is fast. The RGBA5555 alpha channel increases the natural transparency effect, but the memory consumption also increases. RGBA5551 is better than RGBA4444 for those with less transparent gradient. RGB565 is a little worse than RGB888 in effect, but it is acceptable for some pictures, but it does not have an alpha channel. RGB888 has fewer alpha channels, and its memory footprint is three-quarters of that of RGBA8888. But the memory consumption is half of RGBA8888. Memory consumption 32bppД¬ompared with RGBA8888, the effect of RGBA4444 is a bit more lost on some pictures. RGBA8888 works best to consume more memory.

At present, the background without an alpha channel is used. The effect of compression to 80% is not much different from the original image, but the compression ratio is very scary, the file is small and the effect is good. Jpg has no alpha channel, so it is often used for background images. Pvr3ccz pvr3ccz is an upgraded version of pvr2ccz, adding some functions, you can use other pixel formats such as ETC1, pvr2ccz was not supported before. The png8 file is small, but the effect has some loss compared to png, and the loss of some image gradient processing effects is more obvious, if the effect is not past, use png Texture output format, commonly used png, png8, pvr3ccz, pkm, jpg. pvr2ccz PowerVRВ TextureВ Format,В PVRВ VersionВ 2,В compressedВ withВ zlib,В cocos2dВ header,В deprecate.pvr2gz PowerVRВ TextureВ Format,В PVRВ VersionВ 2,В compressedВ withВ gzip,В deprecated.pvr2 PowerVRВ TextureВ Format,В PVRВ VersionВ 2,В deprecated.jpg JPGВ imageВ format,В lossyВ compression,В noВ transparency.pvr3ccz PowerVRВ TextureВ Format,В PVRВ VersionВ 3,В compressedВ withВ zlib,В cocos2dВ header.pvr3gz PowerVRВ TextureВ Format,В PVRВ VersionВ 3,В compressedВ withВ gzip.pvr3 PowerVRВ TextureВ Format,В PVRВ VersionВ 3.TheВ formatВ typeВ isВ automaticallyВ derivedВ fromВ theВ sheet'sВ fileВ name.-texture-formatВ SetsВ theВ formatВ forВ theВ textures.
