PixInsight 1.7.4 Released

[astropixel]

Linux 64bit ubuntu - working well. Unzip and extract to user directory, or write over old installation. More responsive than previous version. Very nice. Thanks Juan.

Is there  a new PCL version as well?

[Juan Conejero]

Hi Georg,

Is there  a new PCL version as well?

Yes, of course. I'll release it during the next days. It is a transitional release before PCL 2.0, which I'd like to have ready on next Spring. PCL 2 will be an open source library released under PCL license.

I also have to publish the source code of your GradientDomain module. As you surely have noted, there are a few identifier changes (e.g. 'Gradient' instead of 'Gradients', 'HDR' instead of 'Hdr', etc, which we have made for coherence with platform guidelines. However, all existing instances (icons, projects, etc) continue working thanks to new PCL 'aliasing' features. Allow me a few days of rest and we'll release everything.

The previous core worked with a big image for ~90Mpx in the mosaic's mode, but the new one doesn't want to work: it reports that there's not enough memory.

OS: Ubuntu 11.04 32-bit
RAM:  5GB

That happens because you're working at the limit of 32-bit addressable memory. The Linux kernel won't provide more than 3 GB to applications. This is true no matter how much memory you have installed. Along with that total limit, the maximum size of a contiguous memory block will always be relatively small (smaller and smaller as more memory gets allocated),  and may lead to an out of memory condition even if there's plenty of unused memory. This is a problem common to all 32-bit operating systems.

The *only* solution: install a 64-bit Linux distribution and run a 64-bit version of PixInsight. Unless you have a vintage machine you already have a 64-bit capable processor, and a 64-bit Ubuntu will manage your 5 GB of RAM nicely. Please note:

- All 32-bit versions of PixInsight are now obsolete. We no longer try to optimize our tools to run on 32-bit operating systems.

- So far we have been releasing 32-bit versions of PixInsight for compatibility with legacy hardware. Soon we'll discontinue them for Linux and Mac OS X (now that we have a stable Cocoa-based version for Mac OS X). We'll continue releasing a 32-bit version for Windows for some time because Windows is not free and there are many machines (mainly laptops) with 32-bit versions of Windows installed. The FreeBSD port of PI is already only available as a 64-bit application.

Juan,

Looking good on Mac OS X Lion, 64bit - it looks as if a lot of the minor but irritating UI glitches are gone. Getting image window focus seems much cleaner - no more of that problem with the lost cursor on overlapping windows.

I'll let you know if I see any problems, but so far so good.

Thanks,

Sean

This is a transitional version to stabilize the platform in preparation to more important releases that we'll see in 2012.

OMFG!! You're adding LAYERS!!!
