Blend two image into 1 image

[minhdl93]

Hi,

I want to blend two images into one image like in matplotlib. Is it possible? Because when I tried this code, it plotted two images

`isns.set_image(cmap="magma", origin="upper",despine=True)

    isns.imgplot(im.resize((w, h), Image.ANTIALIAS),alpha=0.5)

    isns.imgplot(dec_attn_weights[0, idx].view(h, w))

    plt.show()`

Hi @DangLienMinh - Yes, that is possible with the ax parameter.

You can do the following -

ax1 = isns.imgplot(IMG_1)  # Generates first image
ax = isns.imgplot(IMG_2, ax=ax1)  # Adds second image to the axes of the first image

Note the ax=ax1 in the second function.

Hi @SarthakJariwala, Thank you very much for your help. I tried the mentioned method. However, the result was like this. Only one image was displayed

` isns.set_image(cmap="magma", origin="upper",despine=True)

    ax1 = isns.imgplot(im.resize((w, h), Image.ANTIALIAS),alpha=0.3)

    ax = isns.imgplot(dec_attn_weights[0, idx].view(h, w),ax= ax1)

    plt.show()`

I want something similar to this where image 1 overlay image 2

You would want to have the alpha parameter for the second image (the image that you are plotting as the overlay). Otherwise, if the second image is opaque, it will completely block the first image (basically the result that you got).

So, you can try -

ax = isns.imgplot(dec_attn_weights[0, idx].view(h, w))
ax = isns.imgplot(im.resize((w, h), Image.ANTIALIAS), alpha=0.3, ax=ax)

Thank you very much. It worked perfectly
