Qt QImage帮助文档中的表格

constant	value	Description
QImage::Format_Invalid	0	The image is invalid.
QImage::Format_Mono	1	The image is stored using 1-bit per pixel. Bytes are packed with the most significant bit (MSB) first.
QImage::Format_MonoLSB	2	The image is stored using 1-bit per pixel. Bytes are packed with the less significant bit (LSB) first.
QImage::Format_Indexed8	3	The image is stored using 8-bit indexes into a colormap.
QImage::Format_RGB32	4	The image is stored using a 32-bit RGB format (0xffRRGGBB).
QImage::Format_ARGB32	5	The image is stored using a 32-bit ARGB format (0xAARRGGBB).
QImage::Format_ARGB32_Premultiplied	6	The image is stored using a premultiplied 32-bit ARGB format (0xAARRGGBB), i.e. the red, green, and blue channels are multiplied by the alpha component divided by 255. (If RR, GG, or BB has a higher value than the alpha channel, the results are undefined.) Certain operations (such as image composition using alpha blending) are faster using premultiplied ARGB32 than with plain ARGB32.
QImage::Format_RGB16	7	The image is stored using a 16-bit RGB format (5-6-5).
QImage::Format_ARGB8565_Premultiplied	8	The image is stored using a premultiplied 24-bit ARGB format (8-5-6-5).
QImage::Format_RGB666	9	The image is stored using a 24-bit RGB format (6-6-6). The unused most significant bits is always zero.
QImage::Format_ARGB6666_Premultiplied	10	The image is stored using a premultiplied 24-bit ARGB format (6-6-6-6).
QImage::Format_RGB555	11	The image is stored using a 16-bit RGB format (5-5-5). The unused most significant bit is always zero.
QImage::Format_ARGB8555_Premultiplied	12	The image is stored using a premultiplied 24-bit ARGB format (8-5-5-5).
QImage::Format_RGB888	13	The image is stored using a 24-bit RGB format (8-8-8)
QImage::Format_RGB444	14	The image is stored using a 16-bit RGB format (4-4-4). The unused bits are always zero.
QImage::Format_ARGB4444_Premultiplied	15	The image is stored using a premultiplied 16-bit ARGB format (4-4-4-4).
QImage::Format_RGBX8888	16	The image is stored using a 32-bit byte-ordered RGB(x) format (8-8-8-8). This is the same as the Format_RGBA8888 except alpha must always be 255.
QImage::Format_RGBA8888	17	The image is stored using a 32-bit byte-ordered RGBA format (8-8-8-8). Unlike ARGB32 this is a byte-ordered format, which means the 32bit encoding differs between big endian and little endian architectures, being respectively (0xRRGGBBAA) and (0xAABBGGRR). The order of the colors is the same on any architecture if read as bytes 0xRR,0xGG,0xBB,0xAA.
QImage::Format_RGBA8888_Premultiplied	18	The image is stored using a premultiplied 32-bit byte-ordered RGBA format (8-8-8-8).
QImage::Format_BGR30	19	The image is stored using a 32-bit BGR format (x-10-10-10).
QImage::Format_A2BGR30_Premultiplied	20	The image is stored using a 32-bit premultiplied ABGR format (2-10-10-10).
QImage::Format_RGB30	21	The image is stored using a 32-bit RGB format (x-10-10-10).
QImage::Format_A2RGB30_Premultiplied	22	The image is stored using a 32-bit premultiplied ARGB format (2-10-10-10).
QImage::Format_Alpha8	23	The image is stored using an 8-bit alpha only format.
QImage::Format_Grayscale8	24	The image is stored using an 8-bit grayscale format.
