How to use a grayscale color model in converting a colored image

how to convert a colored image into grayscale using :
ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
int bits[] = new int[] {8};
ColorModel cm = new ComponentColorModel(cs, bits, false, false,
Transparency.OPAQUE,
DataBuffer.TYPE_BYTE);
please only this method , i don't need the "bandcombine" method cause i need to know that i have exact 256 grayscale colors, thanx in advance.

I went into mail preferences in the first place. I found the fonts and colors and picked the color I want but it doesn;t seem to be sticking?

I am able to get color images in the continues shot but when i try to snap a color image which i need for my processing i get only a monocrome image

I have been using lv_vfw.llb VI's for grabbing images from a CREATIVE WEB CAM ,i am able to get color images in the continues shot but when i try to snap a color image which i need for my processing i get only a monocrome image ,i have been trying to play around with the RGB weightings but i am unable to get a color iamge,it shall be of great help if you could help me in doing this as it is urgent for me.Thanks for your help.

vicky,
I am unfamiliar with the lv_vfw.llb, and have not used it before. However, I noticed that you stated that you are able to grab in color, just not snap in color. If this is the case, why not just perform a grab and then extract a single buffer from this grabbed data, which would likely be in color? This seems like a possible solution to the issue that you are seeing.
Other than that, I really don't know enough about the lv_vfw.llb to be of much help on this issue. Hopefully another member of this forum will be able to assist you with this software.

How to find out embedded raster image is Black&White or Color image?

Is there any possibility to find out the embedded raster image is Black&White, Gray image (or) Color image in "illustrator cs3" without using color mode shown in "document info" pannel. Kindly advice me, the possibilities and solution. And also any scripts avilable for this?
Thanks.

Or you could select the embedded image, and open the Window>Document Info panel. Select Embedded Images from the fly out menu on the Document Info panel. This should give you the color mode and more info on the embedded file in question.

Problem using IMAQ Array to Color Image vi

I am doing some pixel manipulation & while going from an image to an Image Pixels (U64) array using IMAQ Color Image to Array VI I cannot see the image once it is modified.
I am...
1) converting the image to the 64 bit pixel data using IMAQ ColorImage to Array.vi
2) doing the manipulation
3) converting back to an image using the IMAQ Array to ColorImage.vi using the 64 bit input.
What I get is...
1) a black image with data behind it... meaning... if I take the magnifier tool and go to the approximate locations of my image where I expect to find the manipulated data, it is there.
2) cast that image to a 32 bit image & still get a black image for the output. The data however is no longer there and appears to have been stripped.
3) no error's out of any VI's...
TIA

With Vision 2009 situation is not better.
It happened because U64 image displayed in full scale. So, if you have full range of intensities (from 0 to 65535), then you can see something. But if your intensities in small range, for example, 0...255 in all channels, then you will see black image.
Feel differences:
It should be possible to map U16 values into U8 display range with given range (like IMAQ WindDisplay Mapping does), but right now this feature available for I16 images only, not for U64. What you can do is following - map each channel to U8 (with linear LUT, for example), put channels together, then display 32 bit RGB instead of U64.

Bridge displays color images as b&w

I assume this has something to do with settings in Bridge CS4, my platform is MacBook Pro OS 6.8.10.
This question might confuse some people. To beging with, I do shoot my images in RAW files, I even have Bridge convert them to DNG files.
Upon download the images are displayed in color as they should be for RAW files. After editing images in Camera RAW, I convert most all images to sRGB. When some of those edited images come back to Bridge, they might be presented in B&W, though no color is lost to the file upon displaying in Photoshop, and I did not edit the file to be a B&W image. I have DNG, Canon RAW, Tif and Jpeg files, and most of these are displayed in color, but some are not, and I have not figured out the missing link just yet. So to be clear, I have Jpeg color images, displaying as b&w images, but they are color images. Only b&w images should be displayed as b&w.
This problems started once I learned I could edit one image in photoshop out of a series of images, then after editing, i could bring the single photo file back to bridge, and then copy/paste image settings onto a groups of images in Bridge, and all those images would then have the same adjustments made to them as a batch edit adjustment.
But now sometimes I get a B&W display on some images even when I do not apply a Bridge settings edits, and when I never edited the image for a B&W display. I has to a setting somewhere in Bridge, and I just have not figured it out yet.
Thanks in advance for all suggestions:

Yammer asked a pertinent question that remains unanswered—is that “settings” badge (small lines-triangles-in-a-circle) shown on the B/W image thumbnails (at least). If you’re not sure, then include a screenshot of a few Bridge thumbnails where some are color and some are B/W, using the little camera icon on the web version of the forum messages.
And the answer is NO!. I only have those showing up associated with the .DNG files (Camera RAW)
Another similar question would be if you see a B/W thumbnail in Bridge, try doing a right-click (or whatever the Mac equivalent is) and choose Open in Camera Raw. Is the image in B/W or color in Camera Raw.
A <Control Click> (on MAC), opens the .jpeg file in b&w, as shown in the thumbnail.
Can you upload three versions of one of the images that display as B/W: the original PSD/raw/TIF file, a normal Save As JPG that is in color, and a Save For Web JPG that is B/W? Use something like http://www.dropbox.com/ and post a public download link to the images, here.
NO, I thought I explained that real well. Only the .jpeg file that was saved through the "Save for Web" processing ( that is, the a jpeg the goes through greater compression to reduce image file size for web display), is the image file process that produces the b&w thumbnail in Bridge ONLY. All opened images, of various file formats (ie: DNG, Psd, Tif, Jpeg, & Jpeg for Web), all present Color presentations (for editing in Photoshop, and or in display browsers). It is only the thumbnail of that particular jpeg formatting processing for Web Images that produces the b&w image "THUMBNAIL" in Bridge.
When you Save As JPG or For Web, are you ever overwriting the original image with a new one or do you always save the PS-edited image with a new name?
No, never. I leave my RAW files, as RAW originals, and work on newly names images files.
A theory about what is happening is that Bridge uses Camera Raw to generate its thumbnails, and the images that are B/W have some embedded Camera Raw setting, perhaps pasted from a different filetype, that makes CR think the image should be rendered as B/W, but when you open the images on Photoshop, you are opening them directly, without using the Camera Raw plug-in, so any embedded settings are ignored, and the image displays in its original state without the settings having been applied.
It makes since, (what you are saying), and it certainly does respond in that fashion. Your suggestion to open Ctrl Click, or Right Click to open the thumbnail in Camera RAW, was an interesting test, and the response was to open the previously save color image with a b&w thumbnail, into Camera RAW as a b&w image. So Camera RAW is responding to what is in the xmp settings that describes this images thumbnail to be displayed b&w. It is weird that a browser does not.
As to what is in the window selections for the "Save for Web" editing windows, Presets for jpeg are :
Progressive
Optimize
Embed Color Profile
And I use Embed Color Profile.
Even the Preview button at the bottom of the window, shows the color image as displaying color.
I vaguely remember about a year ago doing some CS 4 Photoshop and Bridge web tutorials from an unnamed tutoring website and guy named D_k_ . It is his fault. Just kidding, I actually enjoy those tutorial.
**** Okay, this is perhaps originating from Camera RAW presets, where you can apply previously made settings to other images and then saved them as Presets. Though I don't have this checked in Camera RAW ( still something goofy is going on there), I did find that in Bridge I can reset the individual "saved for Web" image thumbnail back to the the color image by :
Right Click (Ctrl Click, MAC) on the thumbnail
menu down to the "Development Settings" and select :
"Previous Conversion", and this presents the color thumbnail.
I have now tested all the Camera RAW settings in Camera RAW, by opening an image in each one of these :
Image Settings
Camera RAW Defaults
Previous Conversion
Custom Settings
and then reducing image file size, and saving for the web, while changing file name, and each and every one of these Settings produces a Sepia Toned thumbnail. I found out the images were a subtle Sepia Toned image by enlarging the Bridge Thumbnails bigger for a better view. So I can correct the thumbnail after it has been created, but so far, I can't get the thumbnail to be correct on first creation of the web saved jpeg image file. Regular jpeg image file thumbnails save correctly.

IMAQ FFT of a color image

In LABVIEW 2011 Is there a way to do an IMAQ FFT on a color image? The only thing that seems to work is on gray scale images. When I try to use a color RGB(U32) image, the FFT vi errors out with "Invalid ImageType".
Any suggestions?
Thanks in advance.

Resolution Decrease.vi ‏46 KB

Thank you for the prompt reply Daniel.
What we are attempting is a de-resolution of a hi resolution image to simulate what a 1-4 reduction in resolution using a fiber optic taper will look like to a customer without having to built a very expensive actual optical system. If it proves to be an acceptable resolution, then we can move forward. The point is we need a fiberoptic imaging system due to environmental issues prevernting having an actual camera up close to the work being inspected.
So the idea is to convert the image to an FFT, remove any frequency component above the resolution we would see through the optical magnification, then recreate the image via a reverse FFT. Does that sound feasible or is there a simpler method of simulating a lowering of the resolution of an image? We can work on the gray scale image, as I believe this will prove acceptable for our demonstration. If color is required, we can talk about splitting up the color planes.
Warm regards,
Randy

Convert color images to black&white bitmaps

Hi,
I have black&white scans of public domain books (image format). I use an OCR software to convert them to indexable PDFs (image+text format). However, the OCRed PDFs are insanely big: a 27 MB scanned PDF leads to an indexable PDF of 728 MB! And unfortunately, my OCR software doesn't have output settings, so I have to find a way to compress the files using Adobe Acrobat 9 Pro.
Using Advanced Options > Optimization does reduce the file size, but not significantly. The problem seems to be that my OCR software converts the black&white scans to color images, and encodes them as such inside the PDF. So I need a way to set the image modes back to black&white. I tried using the Advanced Options > Preflight dialog, and selecting "Convert to black&white". However, the resulting PDFs stay about the same size! It seems that "Convert to black&white" converts the images to grayscale, instead of to bitmap.
Any help would be appreciated!

I mentioned "bitmaps", because when I open the original PDF and right-click a random page and select "Modify image..." and open the image in Photoshop, the mode is set to "Bitmap mode": meaning 1-bit mode, containing either black or white pixels. However, when I do "Modify image..." for the OCRed PDF, the mode is set to "RGB Color Mode". I think this explains, in part, the huge size of the OCRed PDF.
Maybe this table will make it more clear:
Original PDF (Bitmap Mode, 132 dpi)
Size: 27 MB
OCRed PDF (RGB Color Mode, 300 dpi)
Size: 728 MB
Now, from the table above, it's clear that I have to reduce the image resolution. So, using the Acrobat's PDF optimizer, I tried the following settings:
Optimized OCRed PDF: Try 1 (Downsample to 132 dpi, JPEG compression)
Size: 733 MB
Optimized OCRed PDF: Try 2 (Downsample to 132 dpi, ZIP compression)
Size: 449 MB
But 449 MB is still huge for a single book. And I don't want to reduce the resolution under 132 dpi, because I will loose quality. Clearly, if the original document is just 27 MB, I should be able to squeeze the OCRed document too. But I don't know how.

Oracle Reports - Unable to generate report with colored image in bitmap mod

Hi,
I am using Oracle reports 6i.
I am generating a post script[.ps] file using bitmap mode.
The layout contains an image. The image is stored in oracle database which is colored image.
But when the report is generated same is being generated with gray color.
Could any one advise on resolving this issue? The objective is to generate the report with colored image and not gray or black&white

What kind of images do you have? Reports only supports a few formats, e.g. JFIF. So, if you have JPG images with EXIF meta information in the header, you have to remove those first.
when the report is generated same is being generated with gray color.What happens if you sent the output directly to the printer?
And what happens if you create a PDF file instead of Postscript?

Color images not rendering; b/w images rendering

Hello,
My production environment is running Oracle 11.2.0.3.0 and APEX 3.2.1.00.12; my development environment is running Oracle 11.2.0.3.0 and APEX 4.1.1.00.23. The development environment was just upgraded to APEX 4.1
I have external files of jpeg images (55,000+) on both systems. There is a mix of b/w and color images.
I'm using OHS in both environments for my Apache interface. I've checked Firefox and Internet Explorer; same results for both.
On the production system all images render as expected, both color and b/w; on the development system b/w images render correctly, but color images do not. They did render correctly before the upgrade to APEX 4.1. There has been no APEX code changes at this point; both screen sets are identical.
I'm using a stored procedure based on the sample image processor code modified for the external files . The digital image catalog table includes a BFILE column pointing to the image file (using file name and directory name to create the BFILE column).
The render code is
<img src = "#OWNER#.obtain_image?p_ref_item = #REF_ITEM_ID# height = "200" />
The stored procedure code:
<CODE>
PROCEDURE obtain_image (p_ref_item IN NUMBER)
AS
v_Mime VARCHAR2(255);
v_Length NUMBER;
v_FileName VARCHAR2(2000);
v_Bfile BFILE;
v_LOB BLOB := EMPTY_BLOB();
BEGIN
SELECT img_mime_cd, bfile_locn, img_file_nm
INTO v_Mime, v_Bfile, v_FileName
FROM digital_img
WHERE ref_item_id = p_ref_item;
-- Obtain the Lengh of the blob
v_Length := DBMS_LOB.GETLENGTH (v_Bfile);
DBMS_LOB.FILEOPEN (v_Bfile, DBMS_LOB.LOB_READONLY);
-- Set up HTTP header
-- Use an NVL around the mime type and if it is a null, set it to
-- appplication/octet - which may launch a download window from Windows
owa_util.mime_header (nvl(v_Mime,'application/octet'), FALSE);
-- Set the size so the browser knows how much to download
htp.p('Content-length: ' || v_Length);
-- The file name will be used by the browser if the user does a "save as"
htp.p('Content-Disposition: filename = "' || v_FileName || '"');
-- Close the headers
owa_util.http_header_close;
DBMS_LOB.CREATETEMPORARY(v_LOB, true);
DBMS_LOB.LOADFROMFILE(v_LOB, v_Bfile, v_Length);
DBMS_LOB.FILECLOSE(v_Bfile);
-- Download the blob
wpg_docload.download_file( v_LOB);
EXCEPTION
WHEN OTHERS THEN
DBMS_LOB.FILECLOSEALL;
END;
</CODE>
Has there been some change in the handling of color images in APEX 4.xxx? I've checked the forum and don't see any such discussion. I've also looked through the release change letters and see no such information.
Any suggestions for where to look next?
Thanks,
George

Line Color and color shadow in smartform with release 46c

Hi, we have a sap system release 46c.
We are developing a smartform, the smartform have a template with multiple box,lines and columns.
We want that the lines will be in one color and some of the box will be filled with a color.
Is possible have color lines in smartforms in release 46c ?
Is possible to fill a box with a color in a smartform in release 46c?
Thanks in advanced.
MANUEL
PS. We are using a template to draw the box.

When you Creating Lines in Tables OR when you creating Templates in SMART FORMS,
You can specify FILL COLOR for each CELL/ROW/COLUMN of Table or Template.
For that you must choose Item(table/template) in Tree in smartforms.
Then you must choose Cell(s) which you want to color-fill, and then choose color from "Shadowing" OR "Shading" ("Оттенок" on Russina) color-menu.

Problem of acquiring color image

Now I try to acquire color image but show in grayscale real time with filter it before. The result is so slow on monitor. How can I do to acquire the filter image faster.Any help very appreciated.

First make sure that you have the most efficient kind of aqusition running.IMAQ LL Ring Without Timeout is the most efficient continous aquisition scheme I know of.
The you must make sure that your conversion and filetering code is efficient. As far as conversion is concerned make sure and use the extract color plane VI and extract the luminance plane. This is the fastest way to do color to gray scale. You can play around with Vision Builder and the Script>>Performace Meter Option until you get a filtering script which is faster than your frame rate.

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.

Convert grayscale to colored images

Hi
I am stuck with my program.
BufferedImage gray = new BufferedImage(bi.getWidth(), bi.getHeight(), BufferedImage.TYPE_BYTE_GRAY);
Graphics g = gray.getGraphics();
g.drawImage(bi, 0, 0, null);
g.dispose();using the above code, i have converted a colored image to a grayscale image.
now my problem is, i want to convert that grayscale image back to colored.
is there any way to do so?
please help
thanks

I am no expert in this, but I believe that when you lose the color information, it is lost forever never to be retrieved, that the basic premise of your program is incorrect. So, perhaps you can store information on what "filters" were applied (I'm not familiar with this "filter" concept) and in what order, and then after you have completed all the gray image processing, apply these filters to the stored colored image and then save it.

I hired a commercial artist to create a color image for the cover of a self published book. I want a black and white image for the inside. The commercial artist has not responded to this request. How do I determine the format of the color image, I'm guess

I hired a commercial artist to create a color image for the cover of a self published book. I want a black and white image for the inside. The commercial artist has not responded to this request. How do I determine the format of the color image, I'm guessing it's Illustrator's formatting but I don't know. How can I find out if Illustrator will open the file and allow alterations? The image opens only in Apple's Pages software?

rons,
It seems that all you have is a raster image, presumable PNG24 or JPEG, in RGB.
It may have been created as raster artwork in Photoshop, or it may have been created as vector artwork with the help of Illy, or as a mixture of vector and raster artwork in either application, or both combined.
If you just need to have a raster representation in black and white based on the current colour image, you may try this, in a new RGB document (View>Smart Guides are your friends):
1) File>Place the image (you may tick Link or untick and have it embedded);
2) Create a rectangle with black fill (R = G = B = 0), at least as large as the image, and place it behind the image (you may ClickDrag with the Rectangle Tool between opposite corners, then Ctrl/Cmd+X+B);
3) Select all and in the Transparnecy palette flyout click Make Opacity Mask with both Clip and Invert Mask ticked.
