How to improve image output get it with montage ImageMagick -


i joined images using montage resolution of image output less images input.

my images input have 640x480 each

but output 256x378

i searching in web , didn't find solution improve output of image quality.

the montage command i'm using

montage -tile 2x3 1.png 2.png 3.png 4.png 5.png 6.png -resize 1024x1024  montage_png.png

anyone know how can better output resolution?

suggestion 1

try way... let montage organise images montage , pass result on convert resizing of result.

montage -tile 2x3 1.png 2.png 3.png 4.png 5.png 6.png miff:- | convert miff:- -resize 1024x1024 montage.png

the intermediate image passed miff (magick image file format) preserves detail , metadata , quality.

suggestion 2

if 5 or 6 images , not hundreds, can in 1 go convert this. need know +append joins images in row , -append joins images in column. joining 1&2 in row, 3&4 in row, 5 & 6 in row , putting 3 rows in stack , resizing result.

convert [12].png +append \( [34].png +append \) \( [56].png +append \) -append -resize 1024x1024 result.png

enter image description here

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
