Saving nonlinear calibration info into a compressed PNG or with no image data
I need to save nonlinear calibration info into the flash memory of a camera. The flash memory available is limited. Fortunately saving a monochrome compressed PNG image is well within the available space.
However, IMAQ Write Image And Vision Info File 2 saves only uncompressed PNGs. Is there a way to save compressed or without image data?
Does the newest version of Vision save any differently?
Thanks ahead for your reply,
Ferenc
I've solved the problem myself.
Under the Calibration Learn Setup for the IMAQ Learn Calibration Template VI I had Learn Error Map and Learn Correction Table set as true. This increased the file size from 240kB to 84Mb.

Does any one know what i need to change. When i'm dragging an image into pages it ends up with the images info and web address rather than the image itself. What should I do?
Thank you.Try dragging the image to the desktop and then to the Pages document or
Select and copy the image and paste it into the document.
It could be that the webpage is making it impossible to knick the image. I have encountered that a few times. -
Saving png photos with different names..
Hello guys,
I am not not so familiar with Labview so i would like some help. I have a Vi which is actually controlling 32 RBG lights.We use DMX protocol..everytime one led is on then we take a picture and then the led goes off..Then the second goes on end so on..we have 8leds in 4corners..So we have corner1_led1,corner1_led2 untill corner4_led8 .So in the end we have 32 png photos saved.What i want is to save the photos with different names and the numbers to start from 1 instead of 0.. For example if we select white light and save the images as "new" the images are going to be named "new_white_0_0" instead of "new_white_1_1" . Do you have any idea how i can change it?
Attached current photos names and Vi.
Any comment would be helpful.
Thank you.

I noticed from your VI that you do a lot of string concatenation to build the file name/path, you can use the format into string and build path VIs to make the block diagram look a little simpler. You could also update the deprecated functions (e.g. the open file) with the modern equivalents.

I am having trouble exporting InDesign CS6 files into JPGs or PNGs
I am not able to complete the export of an InDesign file into JPG or PNG, it has worked fine for me in all other versions except for this one, I keep trying, it takes me all the way to the output setup dialog box and it just doesn't do anything after that. I have looked into all the folders I have to see if by any chance it was saved in a different location but basically there's no trace of anything created.

i followed Michal BLOG /people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14
Requirement :
1) I am able to get the Target file name as same as the source file name when i check the ASMA in Sender & Receiver Adapter , with out any UDF...............this thing is OK
2) I took One field extra in the target structure Like "FileName" & I mapped it Like
Constant(" " )--UDF-----FileName
I Checked the Option ASMA in Both Sender & Receiver Adapters
Here iam getting the Target File name as same as Source file name + Source File name Info in the Target Field " FileName".
I Dont want to get the Target File name as same as Source file name. I want like Out.xml as Target file name.
If i de-select the Option ASMA in Adapters means it is showing " null" value in the target field "FileName".
Please Provide the Solution for this
Regards
BopannaHi All,
Iam able to do this by checking the Option ASMA in only sender adapter itself

I have 2-3 image in my canvas and i want to save it in .psd format means each image will act as a different layer when we will open the saved file in photoshop.
Thanks & Regards,
Parthno dear there is not any option as u suggested.
rightnow i am using my canvas and making the bytearray of it and then I am saving this bytearray with .jpg/.png format with the JPEG/PNG Encoders. but what it does? It makes a single .jpg file of canvas so if there are 3 images in it than it will save entier canvas as .jpg.
I want to save each image as different layer and finally the canvas should be save in .psd format show i can open that .psd file in photoshop..
thanks for the replies
Thanks and Regards,

In Aperture under INFO at bottom it says Badges; if it has an Icon in the block it compresses JPEG image down to KB? Using mail, using drop box with my Aperture and can't figure out how to get rid of 'Badges with the Icon in the box to be able to send full size. Also have been using: "onOne Software" an add on editing program thats awesome, works as a stand alone, Aperture, & Lightroom.
Bottom Line I can't send to lab my web page, or individule without it compressing. Even created a desk top folder droped & dragged in ZIP & still Compression?See this link: Aperture 3 User Manual: Understanding Badge Overlays
The badges in the Info panel have nothing to do with compression. The tell you, if your image has keywords attached, if it is a raw or jpeg image, if has been externally edited, or if it is referenced.
When you send an jpeg using mail, you need to set the image size in Mail to "Acual Size", otherwise will Mail compress the image. For example:
If you have really large images, Mail may not be optimal, because the server of the recepient may refuse to accept large Mail attachments. In that case export the image from Aperture in the resolution you want with "File > Export" and compress it as a zip file. That will not reduce the quality.
Send the zipped file, if it is small enough, otherwise upload it to an ftp-server.
The receiver can uncompress it.

Can I sync Address Book and iCal to put contact info into iCal?
I use Address Book as a contact/customer list and use iCal to prepare my schedule for work. I usually type in the name of the customer I want to see in iCal. Is there anyway to import or drag names out of Address Book into iCal so the location & contact info will be included? I don't want to invite the customer. I just want to input the info into iCal so I don't have retype a name that is already in my Address Book.
If I have customer "xxx" in Adress Book and I am planning on visiting this customer tomorrow. Is there anyway for me to transfer/import this info to iCal without physically typing "xxx"? When I look at my appointment I would love to see the contact info for "xxx" in iCal when I click on individual appointments.
I hope this makes sense.Hi,
You can link to the Address Book entry with a URL. See my script +Link to Address Book+ on this page http://www.nhoj.co.uk/applescripts/ which creates a link from the currently selected person in Address Book. These can then be added to the URL field in iCal or the notes field if you have more than one per event.
Best wishes

Importing into a compressed table
Is importing into a compressed table effective?
I mean is data get compressed when using imp utility to load into a compressed table?
from the oracle doc :
Compression occurs while data is being bulk inserted or bulk loaded. These operations include:
·Direct Path SQL*Loader
·CREATE TABLE … AS SELECT statement
·Parallel INSERT (or serial INSERT with an APPEND hint) statementA quick journey over to the SQL Reference manual, where things like table-create options are defined, gives us the following comment:
table_compression
The table_compression clause is valid only for heap-organized tables. Use this clause to instruct the database whether to compress data segments to reduce disk use. This clause is especially useful in environments such as data warehouses, where the amount of insert and update operations is small. The COMPRESS keyword enables table compression. The NOCOMPRESS keyword disables table compression. NOCOMPRESS is the default.
When you enable table compression, Oracle Database attempts to compress data during direct-path INSERT operations when it is productive to do so. The original import utility (imp) does not support direct-path INSERT, and therefore cannot import data in a compressed format. You can specify table compression for the following portions of a heap-organized table:

I do not get this error with other tables and this file only with this table. Any help would be greatly appreciated, let me know if more info is needed.Thanks that did work out for me. However, I am still curious why I am getting that message in the Enterprise Manager. Well I was able to upload my info into the database and it was a better solution too.

How can I get the script Export Layers to Files to export compressed pngs?
I would love to be able to take advantage of Photoshop's compressed png when using the script Export Layers to Files. I there a way I could modify the script to do this?
TIA!!!
========================
I found it ... I needed to add a line to the pngSaveOptions (around line #886) ...
var saveFile = new File(exportInfo.destination + "/" + fileNameBody + ".png");
pngSaveOptions = new PNGSaveOptions();
pngSaveOptions.interlaced = false;
// trying to compress png files
pngSaveOptions.compression = 9;
docRef.saveAs(saveFile, pngSaveOptions, true, Extension.LOWERCASE);
break;
=========================It does. The standalone XML Export was only offered by itself
in the
registration incentives. Sorry.
