H A DRockchip_FAQ_RGA_CN.md997 …YUV格式存储相对较为特殊，本身排列要求需要2对齐，Y通道单像素存储大小为8bit，UV通道根据420/422决定每四个像素的存储大小，所以YUV格式Y通道需要4对齐才能满足RGA的硬件取数要求，…
1009 **Q2.7**：RGA的fill功能可否支持YUV格式？
1018 Color fill supports YUV format as input source.
1024 ​ 该功能与RGB颜色填充调用一致，通过配置需要填充色彩的RGB值填充色彩，不同的是输出结果可以设置为YUV格式。
1047 …请尝试更新SDK至最新版。由于RGA硬件本身不支持灰度图格式，这里灰度图使用的格式是 **RK_FORMAT_Y400** ，表征为没有UV通道的YUV格式，仅有Y通道的YUV便是256阶的灰度图。
1049 ​ 由于是YUV格式，这里需要注意色域空间的问题，librga中CSC 转YUV格式时默认为BT.601 limit range，而limit range的Y通道并不是0~255，涉及到CSC转…
1059 **Q2.11**：使用RGA其他功能正常，仅在RGB与YUV格式转换时出现严重色差（偏粉偏绿）是什么原因？
1083 **A2.12**：如果输出结果为RGB格式，可以通过 **imblend()** 接口实现，通常选择src over模式，将src通道的图像叠加在dst通道的图像上；如果输出结果为YUV格式，可以…
1087 …2YUV转换，而RGA内部的叠加均需要在RGB格式下进行，所以为了保证RGB图像叠加在YUV图像上，必须src作为叠加的背景图像YUV，src1作为叠加的前景图像RGB，最终由dst通道将混合后的…
