+
+I have an old Sony PRS-T2 which works perfectly. I wanted to put some manga on it but there is this bar on the bottom with the page number that is hidding part of the images ([sometimes also text](https://www.reddit.com/r/Calibre/comments/nyfyap/sony_prst2_space_in_top_missing_text_on_bottom/), so I am not the only one with this problem).
+
+![]({{ '/assets/images/posts/2024/manga_prs-t2/20241219-105624_Prs-t2.png' | absolute_url }})
+
+I think there is other possibilities like css but I did not succeed really and testing was pain.
+
+My files are .cbz in really good quality. I used [KCC (a.k.a. Kindle Comic Converter)](https://github.com/ciromattia/kcc) to convert them in epub, crop them to a specific resolution to get the maximum of it ... here the parameters I used:
+
+![]({{ '/assets/images/posts/2024/manga_prs-t2/20241219-105328__KCC.png' | absolute_url }})
+
+What I did then was just add some pixel at the bottom of the pictures. I used bash via WSL.
+
+*Steps:*
+
+- rename the epub to zip
+- unzip it
+- add the 100 white pixel to the bottom of each pictures
+- rezip in epub
+
+Here the source code:
+
+```sh
+#!/bin/bash -i
+
+wd=$(pwd)
+mkdir converted
+
+for j in *epub; do
+
+	# get the names from the loop needed
+	filenameepub=$j
+	filename=$(basename "$filenameepub" .epub)
+	cp "$filenameepub" "${filename}.zip"     # rename the epub to zip
+	unzip "${filename}.zip" -d "${filename}" # unzip it
+	cd "${filename}/OEBPS/Images"            # go to the wanted directory where the pictures are
+
+	for i in *jpg; do
+		nname=$(basename "$i" .jpg)_temp.jpg
+		mv "$i" "$nname"                                                    # rename the original picture
+		convert "$nname" -background white -gravity south -splice 0x70 "$i" # use imagemagick to add 70px to the bottom
+		rm "$nname"                                                         # remove the temp picture
+	done
+
+	cd "${wd}/${filename}"
+	zip -r "../converted/${filename}_new.epub" "./" # rezip the epub
+	cd "$wd"
+	rm "${filename}.zip" # remove the temp files left
