Reading TIFF images without IMAQ vision

Hi,
Is there anyway to read TIFF images with LV 7.1 but without IMAQ vision? I know it's possible for PNG, BMP and JPEGs, but seems impossible to read TIFFs without IMAQ Vision.
Thanks.
Kian

LabVIEW doesn't do this automatically, but maybe someone has a VI they're willing to share.
Another possibility would be to use an external program to convert the TIFF to another format (BMP for example) and then to read in the BMP picture.
If you're looking to write something yourself, then this might help.
Hope this helps
Shane.

Error encountered while reading TIFF image, Image may be damaged of incompatible. Resave the image w

I am currently running CS3, windows XP, service pack 2, with recent update, 5.03 installed today.
I just opened a 500 page document not in sections where 90% of the document is a placed PDF.
The PDFS were placed using a sample Script that came with Indesign, that instructs the PDF to automatically flow each page after another.
When scrolling through quickly in the pages pallette, I get the follwing error:-
"Error encountered while reading TIFF image, Image may be damaged of incompatible. Resave the image with different settings and try again."
I click OK.
Then I get the following error.....
" Could not complete request because of database error. The File "ABC.indd" is damaged (Error Code: 3).
Click OK....
Then I get the following error....
Adobe Indesign is shutting down. A serious error was detected. Please restart Indesign to recover work in any unsaved Indesign documents.
Then I get the error.......
Indesign.exe has encountered a problem and needs to close. We are sorry for any inconveneince.
And I have two buttons to click....
Debug or Close.....
If I click Debug, it closes Indesign.
Within this window there is also a window to gather further information....I click it and it tells me...
"Indesign.exe....Error Signature AppName: indesign.exe AppVer: 5.0.3.662

To view technical inforamtion about the error report, clikc here....
"Then it creates an error report and tells me where the report is located along with a scrollable window of 0xc0000005 and heap of zeros."
The report conatains a whole heap of CHECKSUM ERRORS.
CAN ANYONE PLEASE HELP??
I had these errors before updating to 5.03 and the patch hasn't rectified anything!!

Open the .inx file in CS3 (that's what you have, right?) and save as a new .indd.
I'd also be tempted to open the tiff in Photoshop and do a save as to re-write it.
Let us know if it helps.
Storing files on the network leaves you more open tot he risk of file damage during transfer and save operations.

How to: Acquire an Image without IMAQ ?

It's possible to acquire an image with a GigE Camera in a labwindows project without the 'IMAQ' Vision Acquisition Software ?
I'm trying to make it with the include functions on "genicam.fp" module, but I don't know exactly how do it.
Thanks

1. So I presume that you do not have the Vision Development Module, or wish to deploy without a Vision Run-Time Licence. These both include IMAQdx as well as the vision software.
Yes, I have one license for the Vision Development Module, and for many commercial projects, I use it ... but the problem is that I need to develop a non-commercial project and can't assume the cost for a new license.
2. Most GigE camera suppliers provide an SDK that will allow you to access the camera. I suggest you go to your camera suppler's website. The cameras from NI are made by Basler, and their drivers and SDK's are here: http://www.baslerweb.com/Support_SW_Downloads-18498.html
Yes, my project is with a Basler Cam and I already installed the Pulon SDK software.
3. I have just done this myself with the Micro-Epsilon ScanControl laser line scanner. This uses a GigE interface; and there was suggestion in the Micro-Epsilon documentation that I could use IMAQdx and the NI vision tools. In fact it seemed easier to use the Micro-Epsilon DLL, so for this application I am not using NI-Vision or IMAQdx. I should note that while the Vision Run-Time licence is a pain, it is MUCH cheaper than anyone else's.
I think the same, I finished the project with a commercial NI license, but in this moment I study the possibility of develop it with a non commercial license for the cause described in point 1 (economic)
4. The alternative is to Google "open source gige camera sdk" This quickly turns up https://wiki.gnome.org/Aravis This states "Aravis has been tested successfuly with Basler, AlliedVision, Smartek and Dalsa cameras. Please see the Cameras page". But you did Google before posting, didn't you?
This option did not know, now I will.
Thanks for all.
PD: With the libraries of bassler for CVI Labwindows, I got open and close the camera, the problem that I dont know exactly what function should I use for a simple capture and happen several errors.

Why I can't subtract two images in imaq vision builder?

Hi,
I have many times tried but failed to get the objects in a image by subtraction with another image which is background, in imaq vision builder(ver. 6.0). I totally can't use the "operators" command under "greyscale" to subtract the two images becauee all commands under the "greyscale" are always unactivated after two images have been stored in 2 idfferent buffers. I really don't know why and this vision builder is so difficult to use, unbelievable! I followed the instructions in its Help and it's quite simple but I totally failed to make this operation!
Two samples of images have been attached and maybe it's very ease for you to filter out objects(fibers) by subtraction each other. Show me your scrip
t if you can. It's urgent to me.
Or the idea of the way I thought for filtering the objects is wrong? Point out please if you know.
Thanks and Merry Christmas and Happy New year!!

Okay, this is not quite as straightforward as it could be, but you can do image subtraction in Vision Builder. The basic idea is as follows:
- select first object image and copy it to buffer 1
- select "image >> get new image" and load your background image from a file.
- put this in buffer 2
- retrieve object image from buffer 1
- perform subtraction. Even though these images appear to be greyscale, they are actually saved as 24-bit RGB images, so you need to use the color operators instead. Vision Builder will only allow you to select steps that are valid for the image you have loaded. You could extract the luminance plane from all of your images to work with 8-bit images if you like.
I have attached below a background image, several object i
mages, my script, and the results of batch processing. You will need to edit the "get new image" step with the correct path to the background image on your machine.
Bruce is right though. This is a bit easier in LabVIEW.

Reading TIFF image in YcbCr photometric interpretation

Hi,
Can anyone tell me what needs to be modified in the following code snippet to read a TIFF image having the YcbCr photometric interpretation.
File file = new FILE(filename)
SeekableStream stream = new FileSeekableStream(file);
ImageDecoder decoder = imageCodec.createImageDecoder("tiff",s,null);
RenderedImage image = dec.decodeAsrenderedImage();
ScrollingImagePanel panel = new ScrollingImagePanel( image,image.getWidth(),image.getHeight());
The following code reads the image but assumes RGB photometric interpretation.
Any info will be helpful.
Thanks,
Panna

try this:
File file = new FILE(filename)
SeekableStream stream = new FileSeekableStream(file);
//add these lines
TIFFDecodeParam tiffparam = new TIFFDecodeParam();
tiffparam.setJPEGDecompressYCbCrToRGB( false );
//change the following line
ImageDecoder decoder = imageCodec.createImageDecoder("tiff",s,tiffparam);
RenderedImage image = dec.decodeAsrenderedImage();
ScrollingImagePanel panel = new ScrollingImagePanel( image,image.getWidth(),image.getHeight());
hope this helps!

How to overlay color image over a grayscale image without IMAQ?

I would like to display a color image over a grayscale image; I would like the color image look translucent. How would I do this without using IMAQ functions? I am currently displaying my grayscale image using Intensity Graph.

Transparency and overlays are really just arithmetic on the images. It
is either done by the windowing system or by you. At the moment you
can't set transparency on LV controls. You can set it on LV floating
windows on some OSes, but then you will need to have the windows lined up.
A more direct approach is to lighten or darken the color image elements
based upon whether they will display over white, black, or a shade of
gray. If the images don't have the same size pixels, this will have a
first step of resampling th
e images so they do. Then combine the pixels
using the transparency you were going to apply to the color and the
shade of gray beneath it. I'm being vague here because there are lots
of physical models for combining colors.
If I look in my paint program I see about fifteen, so this is where you
get to make a choice and decide if black behind a red pixel is black, or
dark red. It all depends on whether these are two transparent
images(acetate sheets) backlit, or is it a transparency over a
nontransmitting media like paper. Anyway, if you can be more specific
about what you want, none of this is hard, typically just scaling the
int32s, adding, and some sort of normalization.

How do you rotate a Tiff picture without using Vision Development software?

Hi:
Does anybody know how to rotate a TIFF picture in Labview if I don't have the complete Vision Development package?
I do have the limited Vision Acquisition software that allows me to do some basic manipulation but not rotate.
The pic is a binary string.
Thanks

Especially easy are the simple rotations (90, 180, 270 degrees)
see: http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=235791
But arbitrary rotations are not that hard either:
see: http://forums.ni.com/ni/board/message?board.id=BreakPoint&message.id=748#M748
(you could even use bilinear interpolation for extra fidelity since the pixels don't map 1:1 for arbitrary rotations, , see http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=166566#M166566)

Are 16-bit greyscale images in IMAQ Vision True 16-bit

Does 16-bit image in Vision control display true 16-bit grayscale (or is it really mapped to 8-bit)?
thanks,
Don

Most displays only provide 8 bits of each color (RGB). These can be combined to create millions of colors, but can still only display 8 bits of grayscale. Very few display are capable of 16 bit display, so the 16 bit images must be converted to 8 bit. It is useful that LV provides several options for the conversion.

Is there an example somewhere that shows how to acquire StillColor images using IMAQ Vision calls?

I need to be able to acquire images from both composite and RGB channels. I am also confused of how to display them and modify display settings as go from color to grayscale to binary.Thanks.

Jerry,
I have attached a CVI example for doing stillcolor acquisition. If you are using LabVIEW, there should also be shipping examples for stillcolor acquisition under labview\examples\imaq\imaq color.llb
To configure your imaq board for stillcolor acquisition, please refer to the following KB

Reading 8kb tiff image and then writing into backend. please help

Hi All, Please Help ..
My aim is to read a tiff image which of 8kb 1732x717 size, and then store it into backend.
what I did is read the image into bufferedImage and then used tiffencodeparam with compression_none but the problem is size is too much after encoding.
code sample
BufferedImage image = ImageIO.read(tiff_filename); to read tiff image
to write tiff image
TiffEncodeParam p = new TiffEncodeParam();
p.setCompression(TiffEncdeParam.COMPRESSION_NONE);
FileOutputStream out = new FIleOutputStream(tiff_filename);
ImageEncoder e = ImageCodec.createImageEncoder(""TIFF,out,p);
e.encode(image);
out.close();

I got all my pictures AND everything else back, folders, ratings, keywords etc
Fortunately I had a backup of the entire iPhoto library folder, it was about 3 months old (I know shame on me) so I didn't want to just use the entire backup folder and lose 3 months of photos.
So I just copied the AlbumData.xml file and the Library6.iPhoto file. PRESTO all my pictures were back WITH all the folders,keywords etc, etc intact!! (up till the 3 month old backup point).
Then I just re-imported the missing 3 months worth of pictures from the original folder in the iphoto library folder. So all I had to recreate was 3 months worth of customization. WHEW!!
Reading through the discussions it seems there is a fair number of users where iPhoto would go empty, but they knew the images were still on the computer. I am not a programmer, but it seems silly to me the their are files that get re-written everytime iPhoto closes....computers crash. and then what happens to the files? Mine got corrupted, lesson learned BACKUP more frequently!!
Thanks to Old Toad who steered me to the Library6.iPhoto as a possible troublemaker in another thread!

Editing metadata in a TIFF image

Hi everyone,
I'm trying to edit TIFF image metadata using ImageIO v1.1 APIs, but something goes wrong...
For a TIFFImageWriter I get the following results:
writer.canInsertEmpty = true
writer.canInsertImage = true
writer.canRemoveImage = false
writer.canReplaceImageMetadata = false
writer.canReplacePixels = true
writer.canReplaceStreamMetadata = false
writer.canWriteEmpty = true
writer.canWriteRasters = false
writer.canWriteSequence = trueSo editing metadata with writer.replaceImageMetadata is not possible (I verified this, an exception is thrown). I thought I could remove an entire image and reinsert it with new metadata, but as you can see writer.removeImage is unavailable, too.
How can I edit a TIFF image without rewriting it to a totally new image file?
Any help will be appreciated,
Giuseppe

Huh... I am in bitmap... OK, how would I go about changing to RGB? Not a complete novice, but never had a similar problem before.

Scale and rotate a tiff image

How do you scale and rotate a tiff image without running out of memory?
I have been trying to scale the image and rotate it before i pass it to the DisplayJAI but i keep running out of memory.
code i use to rotate the image.
private Image rotateImage(boolean rotateRight)
Image img = imageHolder.getInUseImageIcon().getImage();
Image rot = null;
int imageWidth = imageHolder.getInUseImageIcon().getIconWidth();
int imageHeight = imageHolder.getInUseImageIcon().getIconHeight();
int buffer[] = new int[imageWidth * imageHeight];
int rotate[] = new int[imageWidth * imageHeight];
try
MediaTracker tracker = new MediaTracker (this);
tracker.addImage (img, 0);
tracker.waitForAll();
PixelGrabber grabber = new PixelGrabber(img, 0, 0, imageWidth, imageHeight, buffer, 0, imageWidth);
try {
grabber.grabPixels();
catch(InterruptedException e) {
e.printStackTrace();
if(rotateRight)
for(int x = 0; x < imageWidth; x++)
for(int y = 0; y < imageHeight; y++)
rotate[(x*imageHeight)+y] = buffer[((imageHeight-y-1)*imageWidth)+x];
else
for(int y = 0; y < imageHeight; y++)
for(int x = 0; x < imageWidth; x++)
buffer[(y*imageWidth)+x] = rotate[((imageWidth-x-1)*imageHeight)+y];
for(int y = 0; y < imageHeight; y++)
for(int x = 0; x < imageWidth; x++)
rotate[((imageWidth-x-1)*imageHeight)+y] = buffer[(y*imageWidth)+x];
rot = createImage(new MemoryImageSource(imageHeight, imageWidth, rotate, 0, imageHeight));
catch (Exception e)
e.printStackTrace();
return rot;
this is the code i use to scaled the image.
Image scaled = originalImage.getImage().getScaledInstance(
(int)(currentWidth * 1.5),
(int)(currentHeight * 1.5),
Image.SCALE_FAST);
I tried this method, it works and does what i want but the scrolling and loading is too slow.
public void paintComponent(Graphics g)
Graphics2D g2D = (Graphics2D)g;
g2D.rotate(Math.PI/2, (int)dimension.getWidth()/2, (int)dimension.getHeight()/2);
g2D.drawImage(image, 0,0,(int)dimension.getWidth(), (int)dimension.getHeight(), this);
Help plss.
