Internal pixel format w/ 8800GT & 2600XT

I'm trying to start cc'ing an hour long documentary and figuring out hardware needs.
My MP's 7300GT gives only 8-bit or floating point "internal pixel format"s.
Footage is mainly 1080i50 hdv and possibly going to dci.
MP is 2007 model so it's really hard to choose waht to do:
1) Is "floating point" too gpu intensvie for 7300GT?
2) Would 2600XT enable 10-bit or 12-bit and would it even work with MP2007 & color?
3) Would 8800GT enable 10/12/16-bit and how many weeks/months does it still take for nvidia to make MP2007 efi for it?

Ok,
but still Apple has sold Color for almost an year, so they should know how it works.
When trying to build a reliable system for critical work, Apple has had an advantage since it offers both hardware and software (including os).
So it is unacceptable that in this case right hand does not know what left hand does.
Why didn't they test new graphics cards, which they sell by themselves, with software, that they also sell?
If they did, why they don't publish their findings?
And why would they offer 8800GT as their higher end option for new MacPro, but don't tell that it limits the usage of their FinalCutStudio2 package?
Am I understanding correctly, that Alexis Van Hurkman has told that Nvidias lack of color depth options also apply to 8800GT and since ATI has supported all those options, it still does support all of them with 2600XT?
Will this choise of card (8800GT vs. 2600XT) really be a difficult trade off between color depth in Color and playback speed in Motion?

Problem using byte indexed pixel format in setPixels method of PixelWriter

I try to construct a byte array and set it to a WritableImage using PixelWriter's setPixels method.
If I use an RGB pixel format, it works. If I use a byte-indexed pixel format, I get an NPE.
The stride etc should be fine if I'm not mistaken.

}If there's no solution, maybe someone knows a workaround? We chose to use indexed format because of data size / performance reasons.

You have found a platform bug, file it against the Runtime project at => http://javafx-jira.kenai.com with your sample code and a link back to this forum question.
Byte indexed pixel formats seem like a feature which was never completely (or perhaps even hardly at all) implemented to me.
The PixelFormat type your failed case is using is (PixelFormat.Type.BYTE_INDEXED):
PixelFormat<ByteBuffer> byteIndexedFormat = PixelFormat.createByteIndexedInstance(colorPalette);
System.out.println(byteIndexedFormat.getType());These are the valid PixelFormat types =>
http://docs.oracle.com/javafx/2/api/javafx/scene/image/PixelFormat.Type.html
BYTE_BGRA
The pixels are stored in adjacent bytes with the non-premultiplied components stored in order of increasing index: blue, green, red, alpha.
BYTE_BGRA_PRE
The pixels are stored in adjacent bytes with the premultiplied components stored in order of increasing index: blue, green, red, alpha.
BYTE_INDEXED
The pixel colors are referenced by byte indices stored in the pixel array, with the byte interpreted as an unsigned index into a list of colors provided by the PixelFormat object.
BYTE_RGB
The opaque pixels are stored in adjacent bytes with the color components stored in order of increasing index: red, green, blue.
INT_ARGB
The pixels are stored in 32-bit integers with the non-premultiplied components stored in order, from MSb to LSb: alpha, red, green, blue.
INT_ARGB_PRE
The pixels are stored in 32-bit integers with the premultiplied components stored in order, from MSb to LSb: alpha, red, green, blue.As the native pixel format for a WritableImage is not the same as the pixel format you are using, the JavaFX platform needs to do a conversion by reading the pixels in one format and writing them in another format. To do this it must be able to determine a PixelGetter for your PixelFormat (the PixelGetter is an internal thing, not public API).
And here is the source the determines the PixelGetter for a given PixelFormat type:
http://hg.openjdk.java.net/openjfx/8/master/rt/file/06afa65a1aa3/javafx-ui-common/src/com/sun/javafx/image/PixelUtils.java
119     public static <T extends Buffer> PixelGetter<T> getGetter(PixelFormat<T> pf) {
120         switch (pf.getType()) {
121             case BYTE_BGRA:
122                 return (PixelGetter<T>) ByteBgra.getter;
123             case BYTE_BGRA_PRE:
124                 return (PixelGetter<T>) ByteBgraPre.getter;
125             case INT_ARGB:
126                 return (PixelGetter<T>) IntArgb.getter;
127             case INT_ARGB_PRE:
128                 return (PixelGetter<T>) IntArgbPre.getter;
129             case BYTE_RGB:
130                 return (PixelGetter<T>) ByteRgb.getter;
131         }
132         return null;
133     }As you can see, the BYTE_INDEXED format is not handled and null is returned instead . . . this is the source of your NullPointerException.

International date format for birthdays

Hi, my Mac is set up in System Preferenes to use the international date format. However when I go into my Address Book and enter a birthday date for a contact it won't accept the international format. So for example 11/08/1970 gets stored as the 8 November 1970 when I wanted it to be 11 August 1970.
Is there a separate setting for date formats in Address Book?
Thanks for your help.

OK. This appears to be a bug in Address Book. It doesn’t bother me because I always type dates using a non-ambiguous format, e.g. “11-Aug-1970” or “1970/08/11” (which Address Book does interpret correctly). If it bothers you and you don’t want to type the address using one of those formats, you can report the bug in one of the following places:

Using Y8/Y16 pixel format in LabVIEW through DirectShow

I am trying to use Y8 or Y16 pixel format (also called Mono8 or Mono16) on a FireWire camera through DirectShow. However, these formats always showed up as unknown in NI-MAX's "Video Mode" drop down menu. Interestingly, "Snap" worked properly and images were acquired correctly using these two formats in NI-MAX.
I am a bit puzzled why they showed up as unkown. Could this be an issue with camera's own DirectShow filter?
Has any one else used Y8 or Y16 pixel formats successfully in NI-MAX on a FireWire camera? How were they listed in "Video Mode" menu?
Thanks in advance.

Hi,
The list of DirectShow pixel formats that IMAQdx knows about comes from the list Microsoft defines here:
http://msdn.microsoft.com/en-us/library/windows/desktop/dd407353(v=vs.85).aspx
Looking at the uncompressed RGB list (includes monochrome as well) and note that there are no 16-bit monochome formats in that list. The only true "grayscale" formats (those where DirectShow does not give us an RGB color image) are RGB1, RGB4, and RGB8. Any other formats will be translated by DirectShow to an RGB image.
Essentially if your camera is returning an image format that is not listed in Microsoft's defined list of GUIDs, it will show up as "Unknown" and IMAQdx will expect it to be an RGB image. DirectShow will convert the image using whatever filters you have installed to that format.

How to Set Pixel Format for AEGP Plugin???

Hi,
Does Anyone know how to set pixel format (ARGB or BGRA etc) for After Effect (AEGP) Plugin (Source Generator).

It requires the Canon Hacker's Developement Kit (CHDK). It runs off of your SD card and does not harm your camera. Download a program called Stick-

Unable to Edit - "Invalid Pixel Format"

When I click on JPEG thumbnails in iPhoto 9 nothing happens. If I then click the edit button manually, the thumbnails appear at the top arrayed horizontally but, when I click on one, it doesn't open up in the edit window. Each time I do this the following error message appears in the console:
12/13/09 11:44:22 AM iPhoto[687] invalid pixel format
12/13/09 11:44:22 AM iPhoto[687] invalid context
Same issue and error message with Preview.
I only have this issue with my MacMini (early '09) under SL 10.6.2. No problem under 10.5.8 on MacMini or on my MBP under 10.6.2.

I'm joining this party.
Brand new Mac mini 2,53 Ghz with SL 10.6.2 that replaced an 2 GHz mini.
The iPhoto library was already on an external disk (Drobo) so file copy issues are not the cause of this.
And when I connect to the Drobo from another Mac mini (exactly the same model, I just bought 2 of them!), I can open the files without any problems.
So it has to be this particular mini.
The only difference between the two mini's is that the one with troubles runs without a monitor.
The one without troubles has a 23" ACD attached to it.

Need to give internal & external format while creating Data Source

Hi Experts,
Plz share some knowledge for internal and external format in field Tab while creating datasource.
when we will give internal format and External format?
Thanks in Advance.
Regards.
Alok

Hi Alok,
External format is the format for the External data. The external format needs to be converted into Internal format and for that you have to use a conversion exit say for example Alpha conversion routine.
For further details please go through the below link,

How to disable internal TNEF format for mail message?

for exchange 2007/2010
my configuration is as follows:
1. i've added a RoutingAgent, that catches every message that its subject contains
a specific word, then - re-routes it into a dummy domain (dummy.com for example).
2. i've added SendConnector that catches dummy.com in the address space, and
routes it to a smtp listener.
If i send mails from outlook client to another user in the domain, it seems
that outlook wraps the smtp request in TNEF format (where the body and attachments are replaced with winmail.dat file).
If i add a recipient which is outside of the exchange domain, the smtp request is sent well in a regular MIME format.
can i somehow change the internal handling to simple MIME format? i need to
relay it to an external IP...
i tried to disable it in "Remote transport" - didnt work, because i'm routing
those internal mails.
thanks!

Hi,
Please refer the following post about how to disable TNEF in exchange 2010 server:

International Date Format Doesn't "Stick"

I have tried to set the international date and time format to "medium" for both the Dates and Times sections, but no matter what I do the change doesn't stick. Upon restart, the setting has reverted to "short". What can I do to get the "medium" setting to stay?

Hi Jason -
Not sure if this will work but try deleting the presets that are present, then select 'medium' then add the numerical bits that you want into the empty space by dragging them over. Don't forget to hit OK. After this try logging out to see if it stuck or not.

International transfer - format DTAZV

Hi all,
We have an issue where our client wants to implement International transfer payment method (L) using payment medium workbench, format DTAZV. As per my findings the system is using function modules (eg - FI_PAYMEDIUM_DTAZV_30 ) to fetch the data for the payment transfer medium. The file structure of the data is mapped from the structures -- DTADDEQ, DTADDET, DTADDEZ etc. Could you please suggest some table from which the data is being fetched for payment transfer medium.
Payment program -- SAPFPAYM
Payment medium format -- SAPLFPAYM_DE
Please correct me if I am wrong.
Please provide your valuable suggestion on this.

Contacts international 'phone format

Has anyone found an answer to this?
Like many of us I have many contacts in countries other than the USA and while I know you can change the street address format of individual cards to match a particular country format I have been unable to do so with the telephone number formatting. Maybe I've missed something somewhere?
This is what I am talking about. In the regular US telephone numbering when a contact's phone # is entered you get this: (555) 555 5555 or (555) 555-5555.
but when I enter say a French telephone number that should be displayed like: 05.55.55.55.55 it always deletes the spaces/periods and jams all the numbers together like this: 0555555555.
I have found the same problem with UK numbers and other countries too.
So, is there a fix for this that I am missing?
Thanks for any help / advice!

Use the full international format by prepending with +, then country code, city code, number
I'm not at my Mac to test, but I'm pretty sure if you set the country in the address field, it will use that country's (at least Apple's interpretation) format. When I return home, I'll try to see if there is a way to get the "correct" format using the country.

Single pixel formation in Intensity graph

I needed to capture a image using CCD camera. Though it has 16 bit resolution, i need to focus on ONE PIXEL.
The process goes like this. Save the image information in a spread sheet array and then find the max value of the array. Till this step, i am OK.
But how do i get to display this MAX value using intensity graph??
Intensity graph is 2D array which needs X and Y value.
So I need to get the X and Y value of the max value of array. I tried using the max index value of 'Max and Min' array function. But it is of no use since the value comes as 1Dimension but the intensity graph needs 2D information in the form of X and Y value.
Please help me on this. Thanks in advance.

Asking the same question in multiple threads does not help or get you an answer more quickly. Please be patient. Many of us who participate in the Forum do so as volunteers.
Now to your question. As you noted, you can use the Array Max & Min function to locate a pixel with the maximum value. If more than one pixel has that value, this function only reports the first occurrence of that value. The 1D output of the Array Max & Min function contains the indexes of the pixel. So the first element would be the row index (X value) and the second element would be the column index (Y value). What I do not understand is why you want to display just one value on an intensity graph. That seems rather meaningless. Please explain what you want the output to look like.
