在Python中调用`CR ModeInfo`结构体以及枚举类型`CR TrigTypeOpt`和`CR GainLevelOpt`，可以使用以下代码示例：

from ctypes import Structure, c_int, c_float, c_char_p

# 定义CR ModeInfo结构体
class CR_ModeInfo(Structure):
    _fields_ = [
        ('nModeID', c_int),
        ('nImageWidth', c_int),
        ('nImageHeight', c_int),
        ('nCutoffX', c_int),
        ('nCutoffY', c_int),
        ('nBinX', c_int),
        ('nBinY', c_int),
        ('fMaxFrmRate', c_float),
        ('nMaxExpTime', c_int),
        ('nPixelDepth', c_int),
        ('nTrigTypes', c_int * 16),
        ('nTrigTypeNum', c_int),
        ('nGainLevels', c_int * 16),
        ('nGainLevelNum', c_int),
        ('nDefaultGainLevel', c_int),
        ('nRoiX', c_int),
        ('nRoiY', c_int),
        ('szDesc', c_char_p)
    ]

# 定义枚举类型
class CR_TrigTypeOpt:
    CR_FluExtSync = 0x08
    CR_FluIntSync = 0x09

class CR_GainLevelOpt:
    CR_G0 = 0
    CR_G1 = 1
    CR_G2 = 2
    CR_G3 = 3
    CR_G4 = 4
    CR_G5 = 5
    CR_G6 = 6
    CR_G7 = 7

# 创建CR_ModeInfo对象
mode_info = CR_ModeInfo()

# 设置结构体字段的值
mode_info.nModeID = 1
mode_info.nImageWidth = 640
mode_info.nImageHeight = 480
# 设置其他字段的值

# 访问结构体字段的值
print("Mode ID:", mode_info.nModeID)
print("Image width:", mode_info.nImageWidth)
print("Image height:", mode_info.nImageHeight)
# 访问其他字段的值

请注意，代码中的设置和访问结构体字段的值仅是示例，你需要根据实际情况进行修改。另外，`szDesc`字段是一个字符指针，可能需要根据实际情况进行处理。枚举类型`CR TrigTypeOpt`和`CR GainLevelOpt`直接在代码中定义了相应的常量。
