[Minor Feature] Scripting Variables: Image Dimensions

[iwr-redmond]

It would be helpful to be able to dynamically set width and height for an existing image. This would allow, for example, a for loop to process a set of source images with different dimensions, e.g. by multiplying the width and height by a certain amount before using Controlnet Tile to upscale the source image.

Hmm, yes this could be useful for shorthand

Sorry, I am a little busy on holiday at the moment, though here are some long form round about ways to achieve this effect
over a list of image file paths (strings)

# glob a directory

{% for i in unquote("output/*.png", expand=True) %}
    \setp size image_size("{{i}}", format_size=False)
    \setp times_2 format_size([2 * d for d in size])


    # delay expansion (Jinja / shell quirk)
    \print {{ '{{ times_2 }}' }}
{% endfor %}

Or

# glob a directory

{% for i in unquote("output/*.png", expand=True) %}
    \setp size image_size("{{i}}", format_size=False)
    \setp times_2_x size[0] * 2
    \setp times_2_y size[1] * 2

    # delay expansion (Jinja / shell quirk)
    \print {{ '{{ times_2_x }}x{{ times_2_y }}' }}
{% endfor %}

The scaled dimension is just printed here but this could be used to loop over input images while scaling their dimensions with --output-size (and a diffusion / image processing call)

There hasn't been much grass growing under your feet of late. You deserve a holiday!
