GLib-ERROR - gmem.c - failed to allocate n bytes

See original GitHub issue

Hi.

Im trying to save a large image into tile format. I’m using python 3.6.9 and the code : x = pyvips.Image.new_from_file("test.ndpi", access="sequential") x.dzsave("test_folder")

Which works fine in verison 8.4.5.

But in the latest version 8.9.1: GLib-ERROR **: 12:00:36.791: …/…/…/…/glib/gmem.c:135: failed to allocate 32105299968 bytes when trying to use dzsave.

The image is : <pyvips.Image 110592x96768 uchar, 4 bands, rgb>

It was a bug in 8.9.0, it should be fixed in 8.9.1. I see:

$ python3
Python 3.7.5 (default, Nov 20 2019, 09:21:52) 
[GCC 9.2.1 20191008] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyvips
>>> x = pyvips.Image.new_from_file("bild.ndpi")
>>> x.get("vips-loader")
'openslideload'

The problem seemed to be that the initial build did not have libopenslide-dev installed while building. (It is optionallyin : https://github.com/libvips/libvips/wiki/Build-for-Ubuntu)

So, no, i dont think there was a problem in nither 8.9.1 or 8.9.0.

In this case, it would make sense to throw an exception / warning to the user when trying to use openslideload without libopenslide installed.

Thank you for the help
