I use 6.8.1 q16

Is it possible to crop 15px from the right side, 5 px from top, 25 from bottom and 10 from the left side? I use a SP3000 scanner and it leaves mask on all four side, i would like to do a batch job. Thanks.

Yeah i want them in dpi not per centimeter.

i finally got it

Anyway, if only there is more people like you fmw42, always helping the people in need. A huge THANK YOU!

Exactly that same number of pixels in WxH as before!

But the problem is that, when i use code you suggested,

convert *.bmp -units pixelsperinch -density 300 test00.tif

it does only one file and from 3637x2433; 128,31x85,83cm; 72dpi i get 3637x2433; 12,12x8,11cm; 762dpi

How can i convert a .bmp image to a tif image with 300dpi resolution.

My bmp files, scans form a SP3000 scanner, are 72dpi images with size of 128x85cm, I would like to have them at 300dpi 30x20cm without changing resolution.

Can you send an example TIFF of the format you want it to have. We need to understand better what you want. The file I generated above had one layer and 4 channels (RGB and separate alpha). When I open it in PS (CS), it has one layer (background) and 4 channels red, green, blue, alpha 1. What is wr...

Still no luck, maybe it has something to do because when you do the command it makes layer 0 instead of background layer.

I've updated Imagemagick to 6.9.3-4 Q16 x64 and my libtiff is 3.8.2 (gnuwin32 http://gnuwin32.sourceforge.net/packages/tiff.htm) When i open your file in Photoshop i don't see separate alpha channel only dithered image, when i open it in any pic viewer i see image normally. Yes i need simple transfe...

ahh, I use Windows 7, was tired last night and misunderstood you. I posted google link as a reference to a script used, don't mind images there.

When i use command above i get this:



and i need it like this:

Thank you for a superfast response :D I use ImageMagick 6.9.2-3 Q16 x64 This is a link to my dropbox folder with two files (i've lowered resolution to 600dpi because originals are over 100MB): https://www.dropbox.com/sh/v0u2w9pnmgvrzt0/AADUrlXu6NikiQ7WRXvCHGg1a?dl=0 P_scan0006.tif - file created wit...

Hello everyone and sorry for asking maybe a stupid question. I'm using a Vuescan program to scan my negatives, and negfix8 script to remove orange mask. Vuescan saves infrared scan of a negative for purposes of dust and scratch removal. It does that by saving IR scan as an alpha channel. RAW scan th...
