[Feature Request] Hitomi.la DL enhancement #150

Closed Ero-gamer closed 6 months ago

Ero-gamer commented 6 months ago

Feature request to add option to choose between native encoded image format: avif and jxl over webp, jpeg and png for downloads.

When I save images from hitomi.la directly while on browser, I get them as .avif image format which is better compressed compared to .webp. But when I download archive or images from Pupil app, I always get .webp images, and there is no way to download .avif or .jxl image formats.

Possible solution: make saving individual images from Hitomi.la automated.

Android BitmapRegionDecoder used to decode images in this app only supports JPEG, PNG, WebP and HEIF, so we cannot use .avif or .jxl image formats.

For jpeg and png, hitomi got rid of those formats in favor of avif and webp so it does not exist on the hitomi server.

I know that, what I want is avif format. When I save image file on Hitomi website using Brave browser, I get .avif image format. But when I download images from Pupil app, I get images on .webp format only, no option to choose .avif format. Why not add option to download .avif/.jxl format as archive only? So users can choose to download between webp and avif format then view it on device using external app.

I don't know if it is a good choice to let users download the image and not being able to display in app. If I had to add the option to download avif/jxl I think I also have to add support for displaying avif/jxl which is planned for now but not actively in development at this point.

I see, thank you for your fast reply and looking forward to future update when avif/jxl format is added for download/view.

PS: consider Coil as in-app image decoder because it is fast, lightweight, regulary updated, support avif and many other format, has the best image resampling/subsampling quality filter and it is already used by many apps including EhViewer.
