Zooming image and Clear image preview

Hello

there are anyway to set config . when you upload image and click for preview and the image immedietly zooming in 10 times then Original image ? As i am facing issue that when i upload my pic and zoom in, the image is not really clear and the image still too small to see.

my image pixels size is 690 x 35000

on my nextcloud .config is

<?php 'preview_max_x' => null, 'preview_max_y' => null, 'preview_max_scale_factor' => 10, and try those preview generator apps setting occ preview x and y and quality image the result still the same. Anyone have get solution to help me fix this ? as i already do research for 2 days don't find any solution to resolve. thankyou,

I uploaded your new picture:

The preview is minimized because it is uses the browser window only from top to button. (Firefox)

With the click of browser zoom (+) it is shown as preview full size. The preview full size is scaled from 690 x 35000 to 81 x 4096 (div 8,5) on a normal nextcloud installation.

I think there are two problems:
a.) the preview is scaled from top to button and in your case very small.
b.) the original preview size with click on browser zoom is also too small.

I think you must solve both problems. With the configuration for picture preview (if it works) you can only solve the problem b.)

Perhaps you can use https://apps.nextcloud.com/apps/sharingpath and access the pictures direct in your browser. The preview function in nextcloud has different problems for your picture size.

additive:
Perhaps you must first delete your preview images and then reconfigure the preview options.
