Dear everybody!

I took photo of my fav personal book so i can carry around in my ipad. I tried using monochrome but the blackground is not pure white. I tried -lat which improve the text but left the background a dirty mess. I used -level which gave me a almost good result but some text are almost washed out. I have 100+ image to process. I found textcleaner but its script is not for windows.

Any kind souls, do you have some guidance for me and help me out? Much thanks in advance!

My textcleaner seems to work. I get



or try


convert Larry008.tif -lat 25x25+10% result.tif

try adjusting the 25 to smaller values and see if you get any better results depending upon the size of the text and value.

Hi fmw42,

I tried "convert Larry008.tif -lat 25x25+10% result.tif" but got a black image as a result (https://www.dropbox.com/s/w077l7pwyr13h ... t.tif?dl=0)

I am using
Version: ImageMagick 6.9.2-4 Q16 x64 2015-10-10

Since it is working at your machine, what could i be missing at my machine?

Much thanks in advance!

My mistake, it only works for light text on dark background, so do two negates. So try
If on unix, try my script

Aha! Thanks Fred! I finally understand how the +10% and +5% works after seeing the result and googling bit more on the parameter. Thanks man! I am getting the results after following your latest guidance. Thanks again!
