Sun JDS Color Depth

I installed Solaris 10 06/11 on an x86 PC
I found that XSun drivers works well for my video and display
but when login to Sun JDS the Colors are limited.
all descussions I saw in the forum are about Display Resolution , But I think that it is a Color Depth Problem
Please Can any one tell me how to change the color depth for Sun JDS to be 24 bits only ?
Thanks

You typically use the 'fbconfig' command to change colour depth. Check the man page.

Need help with color depth on Ultra 5 (solaris 8)

I have always run Solaris on older equipment, and now I have a machine which is "new" to me, an Ultra 5. xdpyinfo tells me that this machine can do 24bpp color, but so far I haven't been able to figure out how to get the X server to come up in 24-bit mode. (Yes I rtfm'ed but I haven't found it yet.)
Since this is a used machine, I only have the Solaris cdroms, etc. (this is for 2.8 beta-01/01, btw), but not the simple docs which came with it. I didn't find it (surprizingly) in answerbook.
Please help if you know how to solve this one. Thanks

Hi, 
There's two things you have to do. 
First, you need to use the frame buffer configuration utility 
called fbconfig to configure the video card. 
Then, you need to copy /usr/dt/config/Xservers in 
/etc/dt/config/Xservers and edit the file to tell the X 
server what color depth to use. 
For example my copy of the Xservers file, configured for 
a standard 8-bit frame buffer on /dev/fb1 and a 24-bit frame 
buffer on /dev/fb0, contains the following line: 
<pre>
:0 Local local_uid@console root /usr/openwin/bin/Xsun -core -logo -dev /dev/fb0 defdepth 24 -dev /dev/fb1 left
</pre>
Be sure to check the man pages for fbconfig(1M) and Xsun(1). 
Hope this helps.

Solaris 10 - Changing default screen color depth

Hello,
I just upgraded a Sun Blade from Solaris 8 to 10. I have a rather old image display application (ftp://east.la.asu.edu/pub/software/pw-5.23.tar.gz) that is absolutely essential for my work, and it will not run under Solaris 10, either on the CDE or jave/gnome desktops.
The executable for this application was compiled using gcc on Solaris 8, and ran fine on Solaris 8 CDE (v1.4.3?) with the "Most colors for applications" color setting in Desktop Color prefs. With that setup, the application allocated 216 colors when starting up, which was sufficient. If the application could not allocate enough colors, it would use its own private color map, which caused window "flashing," but that was OK.
Under Solaris 10 CDE (v1.6.3) and gnome, the application cannot allocate enough colors, and cannot even start with its own color map.
I re-complied the application on Solaris 10 using Sun Studio 11, and the same problem occurs with the new executable.
I think that the problem may be related to default color depth. Right now, with xwininfo, my Solaris 10 CDE xterms are 24-bit true color. Unfortunately, I think that I may need to set my default color depth to 8-bit pseudocolor for the application to run. How can I change the default color depth of the CDE and gnome desktops to pseudocolor? I know that the application works on HP-UX CDE with the default depth as pseudocolor.
I cannot remember if I had somehow changed the settings for color depth on Solaris 8 to get the application to run. I do know that the xwininfo results for a Firefox browser window running on my Solaris 8 CDE desktop was 24-bit true color. I hope very much that this will be the case if I change my default depth to 8-bit on Solaris 10.
Any help that anyone can provide would be GREATLY appreciated. I am dead in the water without this imaging application. I am a member of the Sun Developer Network, and I don't know if I should post this message somewhere on the Developer Forums. Please let me know if I should.
Thank you in advance!!!!!

Hi,
In my first post there is a link to the code I am talking about. The code is public and available. It was created by Noel Gorelick at ASU. It is based on having an 8-bit Xserver running. There are few users of this code, but I completely agree with you that a new generation of unix-based imaging code needs to be developed that is system and Xserver independent. Optimal code should detect screen depth and open windows with desired color depth automatically, without "flashing.". That way, it could even run under Gnome, which allocates all but 18 8-bit colors for the desktop. Under CDE, the code allocates 224 colors for itself, which is great. The above code will create its own colormap if it cannot allocate enough colors, but there is flashing in that case. Have at it if you wish.
Best regards,
Sparcmaster

How to set color depth to Bitmap image with Java advance Imaging

i have to convert image one format ot bmp format and also set the color depth as 1 bit , 4 bit , 8 bit, 16 bit, 32 bit of image.
has any one done this before. please help me out .

Take a look at the example code here: http://forum.java.sun.com/thread.jsp?forum=20&thread=560573&tstart=0&trange=15
I took an image that was 24 bits/pixel (I guess) and converted it to an indexed color model (8 bits/pixel).
Is that what you mean? (It's also easy to convert to 16 or 15 bits/pixel: use TYPE_USHORT_565_RGB or
TYPE_USHORT_555_RGB.)

AMD FireGL GPU + Creative Cloud app = Color Depth & other Issues

Hello, I am writing this post to help anyone who may have ran into the same issues I am seeing with my AMD FireGL graphics adapter when using the Adobe Creative Cloud app on a windows 7 PC.
I ran into a problem installing and setting up the Creative Cloud app on my new workstation that has an AMD FireGL graphics processor.
First off, the system is new (dell precision m4800, with an AMD FireGL V M5100 GPU), and has all the most current drivers and updates available.. that is to say, this is not a hardware issue.
The system operates just fine outside of the Creative Cloud app, but when I installed and attempted to login to Creative Cloud for access to download Illustrator, etc., the Creative Cloud app would open up and then only display a blank white page. No graphics, no data, just white.
When I got stuck at this point I called Adobe support and spoke to a rep who had seen the issue before. The rep worked around the blank white page in CC by loading the windows device manager and manually disabling the AMD FireGL GPU device to re-install and login to the Creative Cloud app.   This temporarily forced windows to use the default/dummy VGA graphics driver supplied with windows.   With windows using the dummy 256-color vga driver we were able to get the creative cloud app running and get me logged in to install my design software. HOORAY!--or so I thought....
At this point I assumed the issue was resolved, but I found that there was a new issue popping up every time I rebooted my system. Windows would load and log me in using the 32bit color depth setting, but as soon as the Adobe Creative Cloud app started up, my color mode would switch to 256 colors... D`oh!
Obviously I don't want to run at only 256 colors, and neither should you! Adobe, why does my color depth change to 256 colors every time the Creative Cloud app is loaded?
If you want to temporarily reset the color depth to 32bit, you can go to Control Panel -> Display -> Adjust Resolution -> Advanced Settings -> Monitor Tab -> & select "True Color (32bit)" from the Colors drop-down menu. Using this method will allow Adobe Creative Cloud app to continue running 24/7, however this is only a temporary fix, which will need to be applied every time the system is rebooted, or any time a user logs off then back in.. Frankly, its a bit of a PITA, so why bother?
The permanent fix is simple.. go to Start -> & do a Search for "msconfig".   Once found, run the msconfig utility and switch to the "Startup" tab, where you will be presented with a list of boot time startup items. Find the one labeled "Adobe Creative Cloud" and disable it by removing the check mark from the corresponding check box.   Then click OK. You will be warned that a restart may be required.. go ahead and re-start.   This time, when the system boots, Adobe Creative Cloud will not load, and your color depth will remain at 32bit. YAY!
If need be you can always load up Creative Cloud manually from the start menu if you need it, but it will knock your color depth back to 256 colors. Thus far i have had zero issues using adobe photoshop or illustrator without first loading the Creative Cloud app, so it isn't required. If i need updates or need to access other features within the Creative Cloud app i can, but it doesnt need to run 24/7 to use other adobe apps.
The short explanation is that Adobe is failing to fully and properly support the AMD FireGL graphics platform. The adobe rep i spoke to essentially said the same thing, but made certain to blame the graphics device and not adobe software--sure thing boss.   The truth is that the FireGL and its varients have been on the market as long or longer than the nvidia products that are supported fully by adobe.
It is clear that Adobe has made a choice not to fully support AMD Workstation graphics (FireGL) since not only is the Creative Cloud app broken and causing problems, but also no graphics acceleration features work in any of my installed adobe apps.. I basically get a message saying "please us a supported graphics processor". Seriously, how is FireGL not "Supported"?
I am not an AMD or FireGL fanboy.. Frankly I cant stand AMD graphics adapters and I genuinely prefer nVidia on my personal systems. At home, my 5 year old $100 nVidia gaming card is fully supported in all the adobe apps..
At work, however, I have no choice what hardware is provided to me and this lack of FireGL support has negatively impacted my productivity more than once. Admittedly, nvidia has much more market share than AMD in the workstation graphics realm, but that does not mean adobe should just ignore AMD completely!
Hopefully this post will shed some light on issues with Adobe Creative Cloud app and FireGL graphics cards that others may be experiencing.
Good Luck!

Minor correction... I called my GPU the FireGL, which is the old market name.. The current, proper market name is FirePro.. same line, just new branding after AMD purchased ATI.

Font Smoothing/Clear Type disabled on RDP Session, color depth low

Hello
One of our customers has a new laptop Asus G771JM-T7021H with Windows 8.1 on it. The graphics, font etc. is good as long as he works locally. When he connects to the terminal server (2012R2) via RDP, the resolution and font is hardly readable. It seems that
the clear type is disabled, everything is blurry and pixelated. The color depth seems to be very low. We've checked the RDP-configuration and the graphic card driver but couldn't find anything wrong.
Any ideas?

Does duplicating layers from an 8-bit PSD reduce the color depth of a new 16-bit edit?

I have been using several versions of Photoshop over the years starting with CS3, then CS6, and finally CC. Through 2012, all my RAW files were converted using 16-bit color depth in ACR. However, in examining my files recently, I noticed all were in 8-bit color-depth, which likely happened once I upgraded to CS6 and ACR left 8-bit as the default. As such, I now have hundreds of images that I wanted to edit in 16-bits that have been converted to 8-bit starting with my ACR export. The files are all RAWs from cameras like the Canon 5D, 5D Mark III, Olympus OMD EM5, and Sony RX100.
I have 8-bit PSDs of my edits of these files which contains multiple layers. I use features from the Nik and Topaz collections for noise reduction, contrast enhancement, black and white conversion, and sharpening. I also use layered Photoshop features like Selective Color. I want to know if I can simply duplicate the layers from the 8-bit PSD files onto a new 16-bit RAW converted background layer rather than re-edit each and every file. There would be no change in the crop of other reasons why the layers would not match up, but I am concerned that duplicating those layers might throw away the benefit of moving to 16-bit since they were created in an 8-bit color-depth.
As a test, I looked at a few files where I had pushed the shadows and colors to an extent and duplicated the layers from an 8-bit conversion to a 16-bit conversion and could see no difference. I am not sure if this is because Photoshop has become very good at reducing color-depth without a perceptible difference or if I am throwing away information in moving the layers.
I work off of a fairly modern computer and a top-end Eizo CG276 self-calibrating monitor and good video card. I am extremely sensitive to color and shade changes as well.
Thanks for any help, I am a bit stressed at the thought of re-editing hundreds of files from step 1, but it is important to me that I not throw away color information and it is better I start re-editing now rather than years from now.

While raw file contain a 8Bit jpeg previews image in some color space. The RAW sensor data is not a color image and has no color space and the bit dept of pixels depend on the manufacturing. Most sensor produce one value for each pixel 10 to 14 bit seems to be common. Sensors only measure the light intensity not color. If front of each pixel sensor is a color filter which lets Red or Green or Blue light be measured for intensity.
A RAW converter can convert your sensors RAW data into a color RGB image in any color work-space in 8 or 16 bit color depth. No Adobe update went around and scanning your computer looking for 16bit color depth images and convert all of them to 8bit color. Your ACR workflow settings may have been change from 16 bit color to 8 bit color by you or set to 8bit by some update or script used. So you current ACR work-flow setting may be converint tou raw datya into 8bit RGB images. As long as you have you raw files you can reprocess these to produce 16Bit color RGB Image by makinf the proper ACR work-flow settings. You can also change your 8bit image to 16 bit image mode. However this will not recover any color quality lost or posterization that has set in.. It will give you a bit more latitude using Photoshop filters which may help you not get banding posterization.

Display-Color-Depth

Hi there.
After an application-crash (After Effects) and cold restart my monitor-color-depth suddenly switched from millions of colors to maybe several hundreds of colors. I've tried cleaning the caches, throwing out preferences-files (out of library) and also resetting the color-depth by using third-party-applications. Still not working. I suppose it's some kind of problem in one of the preferences-files in the library, but I don't know which one.
The "About This Mac" section shows that the monitor would show some "Millios Of Colors".
As I can not work like this I made a new user-account. In the new user-account everything runs smoothly but for sure I would like to use my old user-account with all my settings and preferences instead of switching to a total blank one that I have to modify again to fit my needs. Does anyone have an idea what could be wrong or how to succesfully force the display to display millions-of-colors again?
When I log into my old user-account the display first shows normally, then switches to "hundreds-of-colors" after a split-second. Is there any way to slow down this process and monitor which preference-file the computer is loading in exactly this moment?
Also weird: when I connect to my old user account via remote access / screensharing (vnc://...) then the display looks normal from the remote computer.
Any ideas would be welcome. Don't know what else to do...
Cheers, Aeiou

What does it say if you go to About This Mac -> More Info -> Graphics & Displays -> Pixel Depth
1: Try resetting the PRAM.
2: Go to System Preferences -> Displays -> Color -> Select another profile or calibrate
3: Go to System Preferences -> Universal Access -> Slide the Contrast bar all the way to the left
Might end up just being a plist to snag though.

How to fix gray background on images without checking "retain color depth"

I have a cover page on my report where the user can insert a logo image. The problem is that if the logo image has a white background it will turn the white background gray. I have figured out how to resolve this by checking "retain original image color depth.u201D The problem with this is that all the images in my report are larger so the report pdf file size goes from 3mb to 30mb. Is there a way to make the logo image appear as normal without having to check the retain color depth? I have tried adjusting the image in photoshop several different ways but havenu2019t figured it out yet.

That is exactly why the option is there. And why it is unchecked. Most people prefer to have smaller report size. The choice is small reports with the option unchecked and the loss of picture quality, or bigger reports with the option checked, retaining the picture quality. THis a by design and is not consiered to be a "bug". If you post the issue into the [idea place|https://ideas.sap.com/community/products_and_solutions/crystalreports] perhaps it will get picked up as an enhancement, but that it the best I can suggest.

W500 - switches to 16-bit color depth after disconnecting LCD TV

Hi guys,
My W500 always changes the screen color depth to 16-bit when I select "Notebook only (factory default)" on Fn+F7 menu, after watching movies on LCD TV. It happens both on Display Port and VGA connector. I have set "separate displays" (no desktop cloning). I remember having the same issue with old T61p. How to prevent that from happening?
cheers,

Color depth

What is color depth of macbook and is it possible to change it? from 32 to 16bit. if so does it improve system performance?

Hi dog,
apple macbook (at system preference) doesn't offer that 16 - 24 - 32 bit depth, but it offer 256 - thousands - millions color.
I think it might make the gpu task easier, but I doubt you will notice the improvement.
Better get more memory to improve your overall system and the gpu shared memory as well.
Good Luck.

Color Depth Choices Removed...Any other way to change?

SL removed color depth choices in displays. We use display link adapters (USB video cards) for extra external monitors (email/web etc) and setting the display to thousands increased performance dramatically. Now we are stuck at millions...
Anybody have some command line fu to change the display color depth?

Changing Color Depth

I need to change the color depth of an external monitor, but it seems this has been removed from 10.6! How can I change the color depth of an external monitor? Thanks!

You can improve the framerate only if your application is fillrate limited, if it is polygon limited you will see no difference.
But yes often you get increased framerates, but beware that using 16 bit colours will on NVidia mean you also use 16 bit Z-Buffer, which can lead to annoying rendering artifacts.
You have two ways to set the colours:
1) Change desktop colours to whatever you wanna use.
2) Use exclusive fullscreen mode, and set colours.
How about rewarding me some duke dollars for that answer? :)

Will mountain lion supports a 10 bits color depth?

Just wondering if and when it will, and how much it affects color accuracy in photography comparing to chain that supports a full 10 bits per channel color depth.
Thanks in advance for your answer.

Its a big deal for me sadly, Lion is still somewhat buggy and I fear it always will be, and now 10.8 comes along, I don't want my main machine to be part of the IOS family. For myself its time to move on from Apple. Great machines but I liked OS X being different to IOS, now the line between both is far to blurred and seeing the same thing on every machine almost is not what I personally want, this is not innovation in my mind just assimilation, time to look for something else why my iMac still has some value.
Then please be realistic. The announcement just came out and people are already arguing over the cost or if it will be free. That will be well down the track. Just get on with using either Lion or Snow Leopard, whatever you prefer and worry about ML when it is released!

How can I watch video encoded with 10-bits color depth correctly via Adobe Flash Player?

When I watching video on a site, one of those video said it is encoded with 10-bits color depth and require Flash Player 10.2+ and non-trident browser to watch it correctly , but with the latest flash player available installed and ising the Firefox, why I still found green vertical bands over the video which is a sign of improper rendering? How can I fix it? Platform using: android 2.3.6 with Texas Instruments OMAP4430.
