2D Picture Control Export as JPG

Hi guys,
I've created a radar plot using a 2D Picture Control. However on attempts to export this by using 'Get Image' I end up with a complete white/black (depends on background colour) square box. So in short, the radar plot created out of 2 variables is not visible.
Any suggestions for exporting a .jpg file from a created radar plot from a 2D picture Control?
Thanks a bunch!

Have you tried the Picture to Pixmap function followed by one the Write JPEG Image file?
EDIT: The snippet is a modification of the shipping example. All that I had selected for the snipper were the three VIs and the wires between them. Nothing else was selected. The snippet posted is what I got. (Didn't have the Code Capture Tool installed on the virtual machine.)

PDA example: Reading a jpeg file into a picture control

Hi
Does anybody have a simple PDA example of how to read a .jpg file and show it in a picture control. The jpg examples I've found does not compile for PDA.

The hard way would be to write your own JPEG -> Bitmap / Array
de-compression routine. You will probably find example (C++) code at
the JPEG web site.

Save content of picture control as .jpg into excel file?

Is it possible to save the contents shown of a picture control as a jpeg file into an excel file along with other data? Is this possible without using ActiveX? If I have to use ActiveX how do I use this?
Thanks

Hello AndyBE,
ActiveX is definitely going to be your best bet. I�ve attached an example that should meet your needs. Let me know if this works for you.

A problem about saving the picture control'image in a child VI.

i want to use 'export image' method to get a picture control'image,so ,i have a child VI to use method 'export image',and a main VI to using the child VI,but when i run the main VI,there is no image is saved on the disk ,but if i open the child VI'frontpanel,then,i run the main VI,the image is saved on the disk,i want to know the reason why i can not get the image,when i run the main vi without the child 'frontpanel or blockdiagram is opened.

The behavior that Simon describes is not a hard and fast rule, and the Export Image method used to be a bit of an exception. It would supposedly update the controls of unopened FPs that used the method. Reality never quite matched what was described in the documentation if I recall.
If you pore over the detailed help you discover that this method works fine in SubVIs with some controls and not others. Look at the characteristic 'Loads the Front Panel Into Memory', for a Picture control it is 'No', for a Waveform Graph, for instance, it is 'Yes'. Caveat: Relying on this level of detail to be correct in the LV help is a bit risky. Best to try it yourself. Not loading the FP is a good hint that the method is not going to behave in a SubVI.
As to the problem at hand, a Picture Indicator is an odd choice to me to use this method. You have VIs in the Picture palette to convert pictures to image data and then export the image data to a PNG or JPG or BMP file directly. Anything you would draw and then export could be exported directly without drawing.

How do I apply a texture to an imported .stl file in 3D Picture Control?

Hi, I'm trying to apply a 2D image as a texture to an imported .stl file in 3D picture control. It works fine if I'm using a standard shaped mesh created in LabVIEW, however is there a way in which a texture can be applied to an imported model that isn't a standard shape, in my case a balloon. I've attached the an image of the Sub vi where I apply the texture. The object just shows up as a flat colour. Do I need to define how the image is applied to the mesh due to it being a non-standard shape? If so, any pointers would be appreciated.
Many thanks.
Oh, I'm using LabVIEW 2009 SP1.

Apologies, been trying all afternoon and then a couple of minutes after posting, I figured it out. Using a property node for the Scenemesh reference, I set the property TextureGenMode to Spherical and it appears to now display the texture on the mesh.

Inserting a small graphics in a picture control

Does any one have an example code for inserting a small graphics/8 bit bmp file (15x15) in a relatively large (240x360) 8 bit jpeg image at known location in LabVIEW using Picture Control? Thanks in advance.

Hello,
To read an image file (BMP, JPG, PNG) and put it into a picture control you can use the OpenG function "draw image from file", and then use the picture control property "Zoom" to fit it correctly.
Here's an example :
You can get OpenG functions from here.
Hope this helps.

A snippet of the code follows.

B) Inster all of the images
C) show the updated image.

Set 2d picture control image

I'm making some palette installers for ease of distribution for some libraries I have written. I'm following the example VIs (search the example finder for "palette API").
I'm having some frustration in setting the new palette icon; the icon constant is a 2d picture control but I can't find a way to drop my image into it, and I can't set it programatically as the 2d picture control VIs only allow me to draw shapes into it.
- Cheers, Ed

In cases like this I often resort to using a transparent classic path as an overlay to catch dropped files. If you do not plan on interacting with the picture control, it is quite easy. Otherwise it is just a few more events to control visibility when the mouse enters the VI with the button pressed.
Just run the VI and drag PNG, JPG, or BMP files to the picture control.

Trouble exporting to JPG

Probably a newbie question, but I'm stumped.
I've created an RGB AI file that consists of a picture with text overlaid on it. The text is a pale yellow (254,254,179). Everything works fine until I export it to JPG. When I do so, the yellow text changes to white. Picture, text style all remain exactly as designed in AI, but the text always goes white. I've run experiments, and this doesn't happen if the color is, say, a red or a blue.
What's going on? How do I fix this?
Thanks for any help.
EdB

I tried some text with your color and used save for web jpeg(low) then tried export to jpg and worked fine.
Open your .jpg in photoshop try moving your eyedropper set to 1 pixel over the image. Mine comes back with 253 250 180 on the jpg low quality. The color shifts when saving to .jpg for compression, and low quality changes the most. Your monitor calibration and color profile settings can be part of the problem. Try changing your illustrator >> edit >> colorsettings to:

Does lightroom honor my incamera picture control profiles?

I've been struggling with this question while importing photos from a Nikon D700.
Sometimes I switch to different picture control settings in Nikon depending on the shooting situation. I use D2x profiles for portraits frequently, but on import, lightroom seems to discard everything and applies "Adobe Standard" to all pics (RAW). Does lightroom care? Or is picture control profiles only apply to jpeg?
Please let me know what is the smoothest way I can import photos into lighroom without having to go through each photo and adjust colors. I'm sure there must be a way to import photos so that they at least reflect what I'm doing in camera.
Thanks in advance

The picture styles the manufactures provide are proprietary raw to JPEG processing in-camera. Only the manufacturers know that recipe.
a bit of a myth this. Manufacturers processes are not unknown. They are not secret in any way. The settings are applicable only to the manufacturers software (or the firmware for in camera production of jpgs). LR uses different (and superior) processing tools, so cannot apply them.
If you wish to use the in camera settings then you can
1 Shoot RAW plus jpg. The jpg will be processed according to the manufacturers settings.
2 Shoot RAW and use the propitiatory tools provided or sold by the manufacturer rather than LR.
Certain proprietary settings are actually shared and used by LR. The lens corrections built into m 4:3's cameras being an example. But the colour profiles, sharpening, noise reduction etc. in LR is different to that used by proprietary software such as DPP or Nikon Capture so these cannot be used directly. Adoe makes it's own camera specific profiles for every camera, these may not match the manufacturers. In the case of some Canon and Nikon cameras Adobe also produce alternative colour profiles which closly match (but are not exact replicas) the ones the camera manufacturer uses.
The "secret sauce" is not the information in the file, but the way each different RAW processing software uses that information. There is no right or wrong interpretation of the data and it is really down to individual preference between LR, Capture One etc. and the various manufacturers software. The biggest problem you have with using Canon or Nikon software is that it only works with Canon or Nikon cameras (which is of course the reason the manufacturers are keen on it). Whereas LR, Capture One etc. works with any camera.
The choice is all yours.

How can I draw dashed lines on a Picture Control?

I have loaded a *jpg map onto a Picture Control.
I then load a file of X-Y coordinates that make-up different legs which are connected.
I need to make these lines dashed. Before I spend time on adding new points in between
points and then alternate between "Draw line" &
"Draw point", I wonder if there is an easier
way of maybe changing the attribute of the
line with "Draw Multiple Lines" ???

I have been trying to draw dashed lines too. I have tried drawing a dash and then putting it in a loop. the loop executes after the user has lifted the mouse and then it gets the end point of the line. the problem is that the line appears only after the mouse has been pressed, dragged and released. I was wondering if you have managed to solve your problem. If yes then could you help me with it.

I am not quite sure if I understand what you are trying to do.
Sounds like you are trying to implement the zoom feature (increasing/decreasing the size of the picture inside a picture control, but not the size of the picture control itself). If this is what you are trying to do, then there is a property node in LabVIEW 7.0 that supports this feature (This property did not exist in LabVIEW 6.1). Please download the LabVIEW 7.0 evaluation version and run the attached VI.
Please let me know if this is not what you are trying to do.
Sincerely,
