pcd conversion issue

[Drobniac]

Hey ppl, whats up?

So I have this problem and I don't know if it is a bug, or if my pcd files are faulty.
When I try to convert a pcd file to a png file like this "magick something.pcd something.png" I always get the following error:

magick: improper image header ` something.pcd' @ error/pcd.c/ReadPCDImage/545.

Now this would be fine and dandy if it was with just one file, but this happens with every pcd file I try to convert... Whats up with that?

Here's the header of one of those pcd files

# .PCD v0.7 - Point Cloud Data file format
VERSION 0.7
FIELDS x y z
SIZE 4 4 4
TYPE F F F
COUNT 1 1 1
WIDTH 1366408
HEIGHT 1
VIEWPOINT 0 0 0 1 0 0 0
POINTS 1366408
DATA binary_compressed

Is this not good? Am I missing something?

What is your full ImageMagick version and platform? Please always provide that. I presume IM 7.x.x.x. I don't think we can definitively answer that without having and example file. Can you upload one to some free service (that preserves your input format) such as dropbox.com and put the URL here?

But I suspect the issue is that ImageMagick reads PCD (Kodak Photo CD) format. It would appear you have Point Cloud Data, which is not the same and I do not know that ImageMagick reads that. See http://www.imagemagick.org/script/formats.php and the list generated by doing

Code: Select all

magick -list format
