Yeah, I just caught that the instructions for installing from source said it might be necessary to run that extra command i just added to the original post. I am now running make check again. Before this install Ubuntu expected me to not use 'magick'. It would say the command wasn't recognized if I ...

After a new install of IM 7.0.7-37 Q16HDRI , I ran "make check". The results had 2 fails: FAIL: tests/wandtest.tap 1 FAIL: Magick++/demo/demos.tap 6 I have opened an issue on the GitHub repo, as the read-out requested - it's here, and includes the test-suite.log - https://github.com/ImageM...

"Maximum TIFF file size exceeded" may mean that you need to install the bigtiff delegate. I started to do that before but left it, as it seemed the library I have, libtiff5, could handle large files too. I didn't know where to put it to install it, and I couldn't find any instructions on ...

@snibgo - it's a good point, about the reference sphere. I wasn't at all sure if that would translate into the grayscale in the same way, or if it would be a translation of that into how grayscales work. But according to GIMP, the modulated image is still a 16-bit image. I"m not happy about the...

https://i.imgur.com/jSMMidd.png That really looks right. It's just a small part in the middle though. Now i'll try it on the whole thing. Edit: for a reference image that is proper 16 bit PNG, an image that is reduced to 4096 x 2048 can be downloaded at the link (12 MB): https://www.moonwards.com/p...

The page on USGS with the file didn't have anything that helped. It's at https://astrogeology.usgs.gov/search/map/Moon/LRO/LOLA/Lunar_LRO_LOLA_Global_LDEM_118m_Mar2014 if you'd like to take a look. The software in which these files are normally loaded, Isis, has a support center. I ended up there on...

Sorry, forgot to do that. The image in the first post shows a large section of the image, behind the histogram dialog box. The original image is also 16-bit grayscale - the file shown is just a section extracted from the middle of it, so the colors should not have been touched. I have tried to look ...

This is a section that is cut from the middle of a file that is an elevation map of the moon's surface. The original is a 16-bit TIFF too large for me to open. I have also reduced the file to 25% its original size, and 50% original size with conversion to jpg. All three resulting images show the gra...

Okay. I'm not used to conventions in code examples - there was a backslash in the example, and it didn't seem to me to be any kind of labelling convention, so i included it. I'll fix that, thanks.

Oh wait, is there really supposed to be a quotation mark after the output file name?

When I tried to copy the syntax in the example, IM couldn't read my file names. convert -extract 4000x4000+44080+21040 \ Lunar_LRO_LOLA_Global_LDEM_118m_Mar2014.tif LOLA-Center.tif convert-im6.q16: unable to open image ` Lunar_LRO_LOLA_Global_LDEM_118m_Mar2014.tif': No such file or directory @ error...

The libtiff5 library is installed, and the Resource limits are all adjusted to be large enough, but when i run convert FileIn.tif -extract 4000x4000+44080+21040 FileOut.tif I get convert-im6.q16: Maximum TIFF file size exceeded. `TIFFAppendToStrip' @ error/tiff.c/TIFFErrors/564. It converted to a TI...

Ok, increasing the disk limit to 70 GB did it. My machine is now working away at resizing the 8.5 GB file to 25%. What came with Ubuntu 18.04 was v6. Compiling v7 for my system i suppose is an option I could try. It is again something i haven't done before. Or I can figure out what is taking up so m...

The one that is 8.5 GB is 92160 x 46080 px and it's 16 bit grayscale. So multiplying those pixels its area is 4.2 GP. I don't know what multiple to put in there to account for the 16 bits, as I don't know how many shades of gray are actually being used. There is 75 GB of space free on my main partit...

Alright, now that I've attempted to convert the image again, it returns a new error. I tried on the image I was trying to process yesterday, and when that failed, I tried on an image that is 8 GB. I have 16 GB of RAM, so I thought that might help. The image I was working with earlier is 22 GB. The c...
