General / Running a script on a bunch of images?
« on: 2011 June 10 08:13:41 »
This is probably easy, but I've searched and can't quite figure it out.
I would like to run a repair column script on a batch of images.....how is this done.

I've tried the image container but can't quite figure out how to run a script on the deal....
I've also looked at process container...but again, no joy.

Is there a tutorial/video?

thanks for the help,

bud

PS...the script was found here:

Wish List / gaps in PI
« on: 2011 June 02 20:17:56 »
I've been reading through the various forums to try to catch up and learn and ran across this thread:
http://pixinsight.com/forum/index.php?topic=2218.0

within it Juan had made this statement:

Quote

If we want PixInsight to be a long-lived project, it is essential to build a complete framework without too 'gaps'. Drawing and painting tools, at least at a reasonable level to compete with the applications you've mentioned and other well-known ones, are one of these gaps in my opinion. Each time a user has to move to another application PI as a whole is hurt.


I agree....and the first thing that comes to mind, for me, is the debloom feature.  As currently configured it would be impossible for me to do a full set of images with two of my cameras...both have pretty good blooms on bright stars.   Now, it is possible to do this first in ImagesPlus, AstroArt 5, MaximDL5 and CCDStack V2....all of which I own.  I could then switch to PI.....but, for what purpose at this point?  Maybe for a better alignment/combine (I'm not sure at this point if it is better)?  I do like many of the wavelet/HDR and other filters, but currently it looks like most of my preprocessing will necessarily be done in one of my other programs.

We are getting close to having our 'first light' from our new OBS in New Mexico, and I'd like to become a bit of an evangel and be able to say "processed mainly in PI", but it may be difficult to do this.

So, lets go gapless and do something with blooms.

BTW.....I keep reading in many of the post that 'it is on the to do list'......is this list available for perusal?

best regards,

PCL and PJSR Development / copying a script
« on: 2011 May 31 17:08:48 »
Juan referenced a script in this thread:

http://pixinsight.com/forum/index.php?topic=806

How do I take this and turn it into a useable script?

I have a camera that has a bunch of bad columns that don't seem to calibrate out....and this might be useful.

understand that I know next to nothing about script writing/programming.

best regards,

Off-topic / Error message when align or integration
« on: 2011 May 31 08:21:49 »
Hi all,

I've been an owner for awhile, but with no new data I haven't been using the program much.  I'm watching Harry's excellent videos and working at the same time...with the new ver 1.7.

When I attempt to align some images with StarAlignment I get an error code:
PixInsight API Error
AttachToImage(): Low-level API function error
API error code = 14:
Invalid image handle

So, I thought I'd try some previously aligned images from CCDStack......no joy...
I get the same error code....so, am I missing something obvious?

thanks for the help

General / Sikuli....script tool
« on: 2010 May 20 16:27:52 »
I'm sure most of you "geeks" (that's an affectionate term) have seen this, but it might have some value.

It looks much like an action ability in PS.  I haven't given it a try, yet, but it looks like it might be useful for running a few scripts or processes without needing to really know how to program/write script.

http://groups.csail.mit.edu/uid/sikuli/

from the website:...the language is from MIT...

"Computer users with rudimentary skills will be able to program via screen shots rather than lines of code with a new graphical scripting language called Sikuli  that was devised at the Massachusetts Institute of Technology. With a basic understanding of Python, people can write programs that incorporate screen shots of graphical user interface (GUI) elements to automate computer work. One example given by the authors of a paper about Sikuli is a script that notifies a person when his bus is rounding the corner so he can leave in time to catch it."

It is open source and looks kind of neat.......and is for Linux, Apple OS and Windows.....

best regards,

General / Well, It's official
« on: 2010 May 06 18:17:36 »
Hi all,

I've been feeling a bit guilty about asking for "wish list" things and other stuff and not being a registered owner.

So, just got the commercial license and reinstalled everything.

And, the new install remembered my desired workspace and process icons......cool.

so.....no more guilt,

best regards,

New Scripts and Modules / Blinking Script
« on: 2010 May 06 09:04:48 »
OK, I'm spoiled.......does PI have an image blink capability?

I have MaximDl, AstroArt, CCDStack and ImagesPlus.
CCDStack is the best of the bunch for blinking....it allows me to load my images for processing....apply a stretch to the lot...and then blink through them to see if I have any obviously defective images.  I can then remove them and continue with the processing......or calibrate and save them...whatever....but it is the blink thing that I'm concerned with right now.

Does PI have this capability.....My looking, so far, hasn't found it.

If not, can it be added?....put on the wish list?

General / Bounds of processing?
« on: 2010 May 05 17:29:16 »
Hi all,

Niall, in answer to a question of mine, was good enough to give me a link to the founding statement of the DSA
http://astro-photographer.org/dsa/statement.html

In reading this, and in the discussion on the use, or non-use, of differing making styles it has caused me to think of a few things.

The first would be....
In deconvolving an image, how far can I go before it starts to become "non-documentary" because of the changing of information?

As an example:  I want to bring out the detail in the arms of a galaxy...say M31.
At what point are to many iterations crossing the line.....or perhaps the combination of a deconvolve, HDR and a DSE?  Each and every process has changed information.  The ultimate purpose being to overcome my horrible seeing and the limitations of my equipment.  My usual method is to do it until pleasing to the eye.  This appears to be very unscientific, but does meet one of the rules of the DSA....specifically to "Produce emotions in the spectator."
While this may have met this specific rule, but at what point does it step over the line?

thanks for any help,

bud

Hi all,

I've been trying a few tuts, and the Dark Scale Enhancement one is giving me fits.

I've done the color space deal.
Then the ATrousWaveletTransformm, but the AWT that I do doesn't match anything from the Tut....in fact it doesn't seem to do much of anything, let alone remove all color....I've tried to match the onscreen steps, and settings, but to no avail.  I've tried this with three different color images.

any ideas.....the on screen tut is from a different version than my current 1.06..could this be the cause?

Once I'm successful on this step it says that I must "To isolate the dark structures efficiently, the result from the previous step is subtracted from the image with PixelMath.  An image without bright small-scale structures is obtained after this operation (Figure 3). ""

How is this accomplished?....by applying the AWT to a "clone" of the original and then subtacting in PixelMath?.....the instructions aren't clear at all.

Wish List / Arrow Keys
« on: 2010 May 02 23:13:44 »
Hi Guys,

I know that I can make small adjustments in the different boxes by typing in the numbers rather than trying to minutely move a slider.....but it is tedious.
Is it possible to add the arrow keys to this adjustment procedure?.....simply click in the box and then use the up and down arrows to make the fine adjustments...First get it close with the slider....then use the arrow keys for the fine stuff.........as we watch the live preview?

General / Layers
« on: 2010 May 02 08:56:48 »
I hope this isn't considered blasphemous, but I find the layers and mask ability to be one of the most powerful features of PS.

In PS I'm able to perform a very "strong" filter...such as sharpening, noise reduction, saturation, or import a deconvolution.....then hide all. I can then use a brush to only apply to the areas that I'm concerned with.
It completely eliminates the need to build specific masks and the amount of masking can be infinitely adjusted with flow and opacity...then applying a gaussian blur to the mask to eliminate any edges......this is, to me, the ultimate in masking.
I've been fooling with the masking ability of PI and it is more powerful than any of the other programs that I have, but it still doesn't give me the fine control that I'd like to have and can currently do in PSCS2.

Now, is this possible to be implemented in PI?

I know I can workaround this by doing the HDR/deconvolution/transforms...etc in PI and then exporting and importing into PS, but it'd be nice to have a single platform to do it on.

I have no idea what it takes to make a process/interface to do this, but it'd be slick as snot if it could be done.

best regards,

PS, I also like that many of the keyboard shortcuts of PI are the same as in PS...very convenient.

General / Linear/Non Linear
« on: 2010 April 30 08:06:35 »
From watching some of the tutorials it seems that it is best to keep the image linear as long as possible ..... for such things as deconvolution, hdr wavelets..etc.
Is this correct?

Now, this is how I am understanding some of the program functions from the tutorials...

When I do a histogram transformation....on the live preview......then drag the new instance icon to the ScreenTransfer it gives the same visual look.
Now I understand that this method will keep the image linear...is this correct?
Also, the histogram transformation ..... by itself....is a linear transformation....is this correct?

Also, is there an information page that lets me know the attributes of the image....specifically if it is now linear/non-linear.  I've checked the history and it doesn't seem to show this

best regards,

bud

General / upgrade integrity/time limit
« on: 2010 April 28 11:03:00 »
I've been reading alot of the requests and it says that more modules will be available in the future....star statistics, bloom reduction....etc....all of which I'd be interested in.

The question....if I purchase the program how long will I receive free updates?.....and are they free updates?

best regards,

General / Workspace saving
« on: 2010 April 28 10:57:29 »
Hi, I am evaluating PI and have watched all of Harry's videos (thanks harry) and am starting to get a feel for the program.

In Photoshop I am able to save various workspaces with tools that I like to use for particular applications....such as the layers palette, actions palette...etc.

Is this possible in PI....I know you can save the process icons, but they apparently need to be reloaded each time.

I'd like to be able to open PI and have the processes that I use the most as shaded icons on the right hand side....or where ever I want them to be on my desktop.

Is this possible?

best regards,

bud guinn

PS...I did a quick search for this and didn't find the answer.....
