尺寸不匹配。:(

print(string(size(channelview(text))) * " != " * string(size(channelview(basis))))

(4, 278, 2195) != (691, 1024)

让图像的尺寸相等，为相互叠加做好准备。

new_basis = channelview(basis)
c_basis = zeros(3,size(new_basis,1),size(new_basis,2))
for i in 1:3
   c_basis[i,:,:] = new_basis
end 

text_new = imresize(text, ratio=2)
text_new = imresize(text_new, size(channelview(text),2)-150, size(c_basis,3))

x = (size(c_basis,2)-size(channelview(text_new),2))
arr_zero = RGB.(zeros(x,size(c_basis,3)))
text_new = [text_new; arr_zero]

c_text = channelview(text_new)
c_text = c_text[1:3,:,:]
c_text[c_text.>0.999999999].=0.0;

print(string(size(c_text)) * " = " * string(size(c_basis)))

(3, 691, 1024) = (3, 691, 1024)

开始叠加。

postcard = c_basis*0.75 + c_text*0.25
postcard = RGB.(postcard[1,:,:], postcard[2,:,:], postcard[3,:,:])

让我们在节日气氛中添加红色！

с_postcard = channelview(postcard)
postcard = RGB.(с_postcard[1,:,:]*2,с_postcard[2,:,:],с_postcard[3,:,:])

保存，以免丢失我们的酷卡！

save("postcard.jpg", postcard)
