Have things gotten worse?
Posted: 2019-02-08T13:59:45-07:00
I *was* able to resize images in the past on far less hardware, but it seems that things are trending down over the years.
I've got a TIFF image provided by the FAA for aviation sectionals (https://aeronav.faa.gov/content/aeronav ... tle_96.zip)
The image is fairly static between revisions (17869x12333 ~96mb)
I've noticed recent releases of ImageMagick tools are failing to read/convert/tile* images of this size regardless of the entries in policy.xml
I've got more than enough memory, drive space, etc to do the work - but alas I get resource limit errors.
An example of my resources (from convert -list resource)
Resource limits:
... so until these issues have been fixed I decided to write/share a sample app (in c#) for those of you who are having issues:
On linux install the mono-develop package and you can do mono-csc ./imgsplit.cs to compile it.
sample usage:
(ya it feels dirty to type .exe on a linux box)
