Blurring image preview

[TroySigX]

Info

• Operating System: Endeavour OS, linux-6.1.11arch
• Terminal: Yakuake
• nvim --version: 0.8.3
• fzf --version: latest

• [ ] The issue is reproducible with mini.sh

fzf-lua configuration

```lua require('fzf-lua').setup({ previewers = { builtin = { ueberzug_scaler = "cover", extensions = { ["gif"] = { "viu", "-b" }, ["png"] = { "viu", "-b" }, ["jpg"] = { "viu", "-b" }, ["jpeg"] = { "viu", "-b" }, }, }, }, }) ```

Description

Image is very blurry when previewing in fzf-lua, like this:

This is the original image previewed through viu in terminal:

This happens due to the limitations of the neovim terminal, open a new terminal with :new | term and run viu inside and the result would be the same, not much I can do about it (that’s why you have to use viu -b).

You can try chafa, it works a bit better inside neovim.

Chafa doesn't work for me, it shows like this:

How do I solve it, here's my config:

local img_previewer = { "chafa" }

require("fzf-lua").setup({
    previewers = {
        builtin = {
            ueberzug_scaler = "cover",
            extensions = {
                ["gif"] = img_previewer,
                ["png"] = img_previewer,
                ["jpg"] = img_previewer,
                ["jpeg"] = img_previewer,
            },
        },
    },
})

Does it work if you open a terminal inside neovim with :new | term and run chafa <image_path.png>?

[TroySigX]

It doesn't

[ibhagwan]

It doesn't

Then you have your answer why it doesn’t work within fzf-lua, these media previews are mere suggestions I have no control over how or if they work within the neovim terminal.

Thank you!

[ibhagwan]

If you’re on Linux and use Xorg I recommend ueberzug, it works differently, it spawns an x-window on top of the preview pane, doesn’t use a terminal so it’s not bound by these limitations, will provide the most crisp previews.

[TroySigX]

It works perfectly, thank you so much!

[ibhagwan]

It works perfectly, thank you so much!

That’s great! Play around with the scaler to get the result you like most, possible options (from the ueberzug project page) are: "crop", "distort", "fit_contain", "contain", "forced_cover" and "cover" (default)
