Legacy ImageMagick Discussions Archive

The image is 17310 x 11310 pixel, 16 bit per channel of depth-color. I mean I have enough memory. I have 4 Gb of RAM, and, where I stop some running not-so-useful processes, I think my PC could also make no swap on HD. What I see is that the PC works to read image - from an external usb drive - than ...

I'm thinking about some different configuration between imagemagick for Linux and for Win.
I'm thinking something like a default configuration more optimized on Linux.
Am I wrong?

Please someone help me!

Can you post the convert string?
Thank you

P.S.: I'm not enable to download image from that link

Hi everyone I tried to convert some big images tif (more than 1 Gb 16bit of color depth) with convert command. I want to rotate them 270° and to reduce them in only 8bit color depth. When I tried it on Ubuntu 13.04 - 4Gb RAM, reading from an USB formatted in FAT32, writing in another USB in FAT32 ...

@Greenkoopa
I've tried to convert one of my tif image with parameters show in thread you have me said - (I think RomanK is a colleague) and it works fine!!!
Thank you very much.

Now I MUST learn to search something in a forum.....

Bye

Thank you very much.

To Greenkoopa: my problem is unrelated to open multiple images, you're right. The first command line I wrote in this forum isn't precise. I don't know if my problem is related to tif file - But I'm quiet sure it is related to a too big output .jp2 file. The image I linked is the most large free ...

Ok.
I can't send you a link to photos that I must convert; they are under hard restriction.
But you can download the Blue Marble 2012 at http://www.nasa.gov/images/content/6184 ... h_full.jpg

In any case, I think you can create one large tif using an up-scale of any image (but I'm not sure).

Thanks snibog and fmw42 for your answers. Now I know another important feature abuot convert. But even if I convert only one file, the program crashes. (I've tryed just 10 min ago to do this) However, the bash script process just only one file each time. Can you try to convert a tif big enough? If ...

Yes, my computer is big enough. I have 4 Gb of memory, I work without X server started, so I can let free so much RAM. When I have all the photos, I occupy 1,6 TB of HD, but this is not a problem. I wrote a bash script that search tif image in a folder, and, if file exists, converts each photo in ...

The command line that I've wrote to convert tif in jp2 is:
Have I some mistake done?

Good morning everyone. I have some images (I think they are one thousand and half) that are in TIF format, RGB 16bit, 17310x11310 pixel. With the convert tool I have now a new image, RGB 8bit. I want to convert it in .jp2 format with high quality (-quality 95), but when I try to do this, imagemagick ...
