我无法解决此错误...我想我无法描述更详细的我的代码：
def loadTexture(filename):
"""load OpenGL 2D texture from given image file"""
img = Image.open(filename)
imgData = numpy.array(list(img.getdata()), np.int8)
texture = glGenTextures(1)
glPixelStorei(GL_UNPACK_ALIGNMENT,1)
glBindTexture(GL_TEXTURE_2D, texture)
glPixelStorei(GL_UNPACK_ALIGNMENT,1)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, img.size[0], img.size[1], 0, GL_RGBA, GL_UNSIGNED_BYTE, imgData)
glBindTexture(GL_TEXTURE_2D, 0)
return texture
我该如何解决这个问题？谢谢
图像似乎没有4个颜色通道。图像很可能只有3个颜色通道。您必须指定格式，GL_RGB而不是GL_RGBA中glTexImage2D。例如：
format = GL_RGB if imgData.shape[1] == 3 else GL_RGBA
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, img.size[0], img.size[1], 0,
format, GL_UNSIGNED_BYTE, imgData)
