Color ramp interpolate

Hello all,
for a numeric with a slider, what is the different between the ATTR_COLOR_RAMP_INTERPOLATE attribute and the GetNumericColorRamp (, , , , &Interpol2) ?
Are they the same or independant of each others ?
If the former, why have duplicates, and if the latter, what's the difference ?
Thanks
Solved!

There is no difference. They both access the same data. We provide accessor functions for commonly used attributes for convenience and readability. You will also notice that the accessor function retrieves multiple related attributes.

How do I add a color ramp to a numerical tank indicator?

Hi,
I'm trying to add a color ramp to a tank indicator. I'm using Labview 2009.
Right clicking the tank, selecting properties gives me a dialog box with several tabs. On the 'scale' tab, there is a tick box 'show color ramp' and a dependable tick box 'interpolate color'.
Unfortunately, I am not able to check the boxes. I'm guessing I have to change certain settings of the tank indicator or something, but I can't seem to find the way to add the color ramp to the tank. Can anyone help?
Thanks in advance.

This is another idea that may also help. I made a tank indicatior with multi sliders giving each one a different color.

Changing color ramp Intensity Graph

Using LV8
Set property nodes High and Low colors
and interpolate is set to Yes
but the color ramp still stays blue
not sure what I am doing wrong?

Hi,
High and Low Colours are just colours for values which are out of range! For the ramp itself you have to set Scaling.MarkerValues (don't know the correct English term because I'm using a German LV).
That should help it.

How can I view the color ramp in LV 8.6 sensor-mapping express vi during run-time?

Hi All,
I've been using the sensor mapping express VI that is new in LV 8.6. When I place the express vi in my block diagram of my main vi I get the normal 'express' style configuration dialog. As a part of the configuration there is a really nice 'color-ramp' control where I can configure ranges; max; min; out -of-range colors and so on.
What I would like to do is have the color-ramp control appear as a control on my main vi's front panel. After I convert the express VI to a regular VI I can't seem to find the connection to this control. Although I have found the sub-vi that the expressvi uses in an .llb here:
C:\Program Files\National Instruments\LabVIEW 8.6\vi.lib\express\express 3d picture\SensorConfig.llb
Can anyone point me in the right direction to do this? I get so deep into all the sub-vi's I end up getting lost-haha!
Thanks - Paul

The characteristics of the color ramp (max, min, colors) are all part of a "colorrampstuff" cluster that is inside the Sensor Mapping express VI. In order to change those values for the express VI, you will need to create a custom express VI that provides you with inputs to this cluster. This is done similarly to creating a subVI. Then you can use a variety of methods to write to the elements in this cluster and change them while the program is running.
It may be easier to place numeric controls on the front panel that write directly to the elements in the cluster than to use a color ramp as a control.

Urgent help required: color template - use color ramp instead

hello,
I want to match color using the color matching vi. i understand you need a color template before executing the system.
however i want to give my users the chance to choose any color from a color ramp and then this should be used an input to the color match vi (template). is this possible????
if yes how... i have put a color ramp in the front panel and then put the output to the input of the color match template but get an error: not a template...
thanks

Hi farhan,
Can you please send in some example code, as I can not find the VI you are talking about. The closest match I have is IMAQ Color Match and this does not have a template input.
Please can you also tell me what version of LabVIEW you are using as well.

How to change colors in Color Ramps

Hello,
I would like to use Color Ramps, and I need to change colors. In help documents, it say that I juste have to right click in the icon and change what I want. But I tried all option and I can't do anything I want.
Can you help me ??
Thanks
David

Seems that I'm not the only one to have problems with color ramps...
Nearly everything was explained in the on-line help. Nearly...
"Complete the following steps to change the colors of a color ramp.
1. Right-click the color ramp or a marker and select Marker Spacing»Arbitrary from the shortcut menu to switch the color ramp to arbitrary marker spacing.
2. Use the Operating or Positioning tools to right-click the marker next to the color ramp and select Marker Color from the shortcut menu to change the color associated with a marker.
3. Select the color you want from the color picker that appears."
Additionnal hints :
After switching to arbitrary marker spacing, suppress all intermediate markers (right click> Delete). Then adjust the colors of th
e two remaining end markers. With some ramps, you will be obliged to move slighty the marker position to get a color update.
If you need to insert intermediate colors, add intermediate markers (right click > Add). Using the text tool, type in the exact value associated with the marker. Select the color you want to associate with the marker.
When finished, switch back to uniform marker spacing.
Have fun...

How Do I Convert at Palette Into a Color Ramp?

Hello,
Is there a way to convert the 5-color palettes created by Kuler into a continuous color ramp?
Thanks,
Doug
Twitter: @dugla

Hi Douglass,
Currently Kuler supports only upto five colors in a color theme. But you can create as many color themes as you desire and download them to products like Adobe Illustrator where they can be added to one conitnuous color library via the swatches panel and exported. To do that you'll need to add them to swatches via the kuler panel or by downloading and importing .ase files. Then within the swatches panel, you can select and drag colors from multiple groups into a single group and export them via the fly-out menu as a continuous color ramp.

CWGraph3d show z axis color ramp

Hello!
I use CWGraph3d. Is possible to show the color ramp (legend) for z axis data? Similar like by Intensity chart.
Thanks for an answer!
Solved!
Go to Solution.

Hi Toni2,
The legend display in a CWGraph3D does not work like that in an intensity graph. It is an ActiveX object and therefore, in order to edit any properties you have to get inside the LabView properties window. Please refer to this knowledgebase article for more information regarding this. You basically have to get inside the object and alter its properties.

3D Plot Color Ramp - Colors to Values

Hi all,
The Color Ramp for 3D plots only displays 3 values; not all values for every displayed color is shown (see below).
The actual values associated with each color is available via the 3D Plot Properties dialog (during edit).
How can I access the values for these colors programmatically such that I can display them to the user?
Thanks,
Battler.
Solved!

You're right that they don't match the values exactly. It also is completely dependent on how the values are set for your particular color ramp, especially whether or not they are evenly spaced. In your first post, you showed a picture with the colors distributed according to the default. The method I mentioned in the previous post gets pretty close to these values (really a little under each of them - has to do with how the default is distributed).
You're also right that this isn't a very good solution. It's a work around to a functionality that I don't think exists. There are probably better work around options - that's just what I came up with.
One question please Alisha.
Are we to accept your work-around as the best answer NI can offer?
I would think a CAR is called for to ensure R&D is at the very least aware of the issue.
A little concerned this will get swept under the rug,

Color ramp not changing to reflect interactive seting of hi/low color boxes

This is using the colorramp associated with the intensity graph, but it's also true of the basic colorramp in Controls->CLassic->Numeric. The colorboxes change color, but the ramp itself remains the default black-to-blue interpolated scale. (labview 6.1, Windows 2000)

The color ramp has a number of colors that control its appearance, up to
about 256 of them. The top and bottom colors are actually the above and
below colors. In otherwords, if your scale goes 0 to 100, the below
color is for intensities below 0 and the above color is used only for
values above 100. Using autoscaling for the Z scale, you will not see
those colors unless you start zooming in by manually changing the Z
scale values. The intermediate colors are set by righ
t clicking on the
markers on the scale. Right click on 100 and there should be a menu
item for Color which will let you change its color. Ditto for 0, and
for any intermediate markers. You can add intermediates by popup or by
dragging another marker onto the scale. You can also drag the
intermediates or type into them to change their location.

Question : Color ramp with overlapping markers

Hi,
I am using a color ramp and would like to understand why, when 2 markers are overlapping, the colors are sometimes switched. In my project, the user is able to create overlapping markers. The problem is that I never know if the ramp will switch the overlapping colors or not.
I made a small VI that illustrates this.
The markers colors go: red-green-blue.
But, on the right ramp, where 2 markers overlapped at 80, the green and red have be exchanged.
I can't find the reason why and I need to understand this in order to have my ramp working properly in my project!
Thank you for your help!

Color ramp with overlapping markers.vi ‏19 KB

Here is an other "funny" example of the problem, when feeding the read(Scale.MarkerVals[]) to the write(Scale.MarkerVals[]).
The overlapping red and green markers switch after each iteration.
This is exactly the problem I get in my program: every time I write the MarkersVals of a previous reading, the colors are switched.
Thanks for helping.

Can I modify the form of a color ramp (I don't want a square but a heart)

Hello !
I want to know If we can modify a color ramp, because mine is a square and I want to have a heart.
If no, maybe can I load an image (of a heart) and make it change of color in function of input datas ?
Thanks !
Solved!
Go to Solution.

veux tu un coeur?? (I hope it's correct )
In the attachment is what you want.
How I did it:
- in Photoshop (you can use something else) i created a picture, crop the middle as a heart, create a new layer and save it as GIF. It is very important to save it as gif because it allows transparent areas of the picture. Saving it as bmp will fill the middle with white.
- open your front panel and drag-and-drop (using the mouse) the created gif file.
- add the "color ramp" (be sure to size it in order to fit to the heart), bring the image to front and send "color ramp" to back (on the toolbar there are some buttons which allow you to set the order of the controls and indicator - front or back)
Now you have your heart.

Color ramp Design issues

I want to design to the right icons ，How to design????

Hi tallahassee,
I still don't get the need for displaying diamond shaped fields.
You still might use the intensity graph, but with some more logic to fill more than one (smaller) pixel with a color.
Like this (using chars to depict colors):
ccbaaa
cbbbac
aabaaa
The "b" also forms a diamond, but is displayed using a rectangular display…

Color is off on my MBP 17" display - cool/purple bias won't go away

I'm disappointed in the color setup of my new MBP 17" Unibody display, compared with the original (2006) MBP 17" that it's replacing. That old machine looked great right out of the box, but on the new one colors tend towards the cool, with a purple tinge in the highlights. Fleshtones look completely wrong, and the contrast is milky, with lifted blacks.
I've gone through the calibration process several times, and while I've improved the contrast, the cool/purple bias will not go away. I bring up the same photo on my old machine and my new machine, and the old one has natural skin tones and rich contrast, and the new one has purple highlights and off skin tones.
I've been told that perhaps one explanation is the fact that the new machines use LED backlights?
Unless I can get this monitor set up properly it's going to be pretty useless to me. Would a hardware calibration tool such as the Spyder help me get the display profile where I need it to be, or is there something inherent in the display hardware that gives it this odd color palette?

The Genius Bar's a suspect place to get possibly complicated CMS/ICC profiling calibration device-level guidance, let alone investigating Apple's apparent driver/default settings to their various and sundry display! You're a brave man! (oops! Forgot I was on the <Apple> Forums- yikes!)...
Seriously, I wouldn't expect any typical Apple Genius Bar denizen to know the ins and outs of what many pre-press folks Graphic Designers, and publishing pros only know of, not know well.
I learned a long time ago, because I was charged with designing, building, testing, and deploying a magazine publishing company-wide CMS, and I didn't want to go hungry, so I learned <fast> ;^)
The first step that I do to eliminate the color cast that does indeed 'color' (sic) almost all stock Apple displays and replace it with a pleasing, more reality-based, warmer overall but with 'clean' color ramps and solids, as well as an accurate white point and proper color and tonal balance. There's the 'free' OS X software-based method, and there's the X-Rite ColorMunki, Pantone Huey, Spyder 3 Elite, or Gretag Macbeth Eye-One Display or Photo... the 'free' OS X method's probably familiar to you- Sys Prefs>Displays>Color>Calibrate>Expert Mode. Perform this simple & brief procedure in a room or surrounding free of harsh, specular lighting, like strong fluorescent lights, or strong sunlight, etc.. Then just follow the directions on each panel in the sequential series of Dialog Boxes, and use the more traditional Mac 1.8 Gamma setting generally and a 6500k White Point; mainly because those two are the 'Old Skool' (well, actually, 5200-5500k White Point's more common setting from Back in the Day, but 6500k is an adequately LONG way from the cold, 'glacial-effect' harshness of any higher WP), and the 1.8+6500k combo strikes an pretty good balance between ultimate accuracy and pleasing warmth. DO NOT check the 'Use Native White Point' box, save the ColorSync display Profile you've just helped yer Mac create for ALL Users' usage, and make certain, before you exit Displays, that you hike on over to the other side of the button, 'Display', and make certain that you've unchecked the 'Automatically Adjust Brightness...' box... NOW exit Sys Prefs, and behold your Band-Aid First Step at getting away from the cold and slanted world of Apple Default Display Profiles. You'll need WAY more accuracy of a good hardware calibration unit if you want to get closer, much closer to Display Nirvana... which brings us to the Next Step. If you've got an LED backlit LCD screen, you'll only need to borrow a unit from someone, or have it done, far less frequently than in days past, because you don't have to concern yourself with the color/brightness/White Point/Gamma/contrast 'drift' of fluorescent-backlit screens, which dim and drift as they age, or the 'phospher aging' of a CRT screen, LED backlit screens need no 'warmuo time', and stay much more consistent throughout their lifespan. Still, you need to somehow get ahold of preferably a Gretag-Macbeth Eye-One Display 2 or the more expensive but more versatile for creating custom ICC/Colorsync Profiles for all your input, output, and display devices, but is about 6 times more expensive than the really good Eye-One Display 2 display calibrator, OR one of the more recent Spyder units, or even an X-Rite ColorMunki (the 'Photo' model, for most users here). I like to avoid the ColrMunki because, amongst other things, it's WAY hard to do what the instructions say you need to in order to produce an accurate profile, and its design gives you way too many opportunities to damage your display. The Huey's a little too basic and less accurate overall than the others, but is still WAY better than our Sys Prefs profile, of which the only reason to perform is to stave off insanity.
Read the manual/PDF, try it slowly and carefully, especially the ColorMunki, which I like less than the others for the aforementioned reasons... experiment with creating two different hardware display profiles with ANY of these calibrators- one with the traditional Mac 1.8 Gamma, and one with the more au courant 2.0 Gamma setting, both with the 6500k White Point, and see which one you prefer for your own use and your own tastes. Even though most calibration unit manuals will order you to stick with the 2.0 Gamma setting, there are many instances where the 1.8 is superior in actual CMS use. Where those instances are is a whole other post; stay focussed on doing the above, and you'll never regret the time, money and energy you put into it- it's a GREAT investment, and one that will go most, if not all of the way you want to go in terms of fixing your Apple Caste' default display conundrum... good luck! =^D
Best,
Charlie

Sample a color from gradient

Hi guys,
1 - How do i sample a color from a gradient in a text? Here is the sample
http://www.pixentral.com/show.php?picture=1TDDZ2kv0TRFDgJ1nNqSVQm25lapV
I keep getting a white circle, like the color is not there. I put a gradient in a circle following this tutorial,
http://vectips.com/tutorials/quick-tutorial-adding-gradients-to-text/
maybe is ok to place the gradient inside the text but then i cannot sample color. How can i do it?
2 - How can i make a beautiful gradient/layer effect like this logo?
http://www.pixentral.com/show.php?picture=17CZROx3OiS23A8jq2WVsfXkY88RHr
Thanks for any info!
Cheers,
S.-

And another way is to simply create a normal blend from 2 rectangles, with your choice of start and end colors from your swatches. The same ones you used in your gradient. This creates a color ramp with as many complimentary blends as you need. In my illustration I used 25.
Now, choose Menu -> Object -> Expand, say OK to the dialog. You can now use the Eyedropper tool to select the colors you would like to add to your swatches. Move the blend outside of the Artboard for future use, or delete it when finished.
TIP: if you want only a certain subset of colors, ungroup the blend after expanding it, choose the colors you want (or all), and then in the swatches pallette, from the top right drop down menu, choose "Add Selected Colors".
Menu -> Object -> Blend Options: choose your steps, then choose Menu -> Object -> Blend -> Make, or Cmd-Alt-B/Ctr-Alt-B
SORRY -- The graphic should say "25 Steps"... I changed it, which you can too, by going back to the Blend Options dialog. Check Preview to see what you're doing, and actually fit the blend directly under your chosen dot over the "i".
