Display .bmp files

How can I display .bmp files with java?

Yes using JAI - using core methods or just the codec.
You only need the jars. A full install on the desktop or server is not required but the C libs a full install provides MIGHT make things a little faster.

Loading bitmap (.BMP) files

I am writing a sort of Image Viewers with Flex 2 - loading
and displaying image files resided in local disk.
Using mx.controls.Image class, I could load and display the
JPG / GIF / PNG files at runtime.
But I could not do the BMP files with the Image class (or
control); what I get is only broken-image icon.
Still I don't understand why the BMP format files are not
included in the "Bitmap object".
How can I load / display BMP files in Flex 2 MXML
application?
Thanks in Advance,
Joseph

Hi,
I have tried the loader.unload(); method and now I get this
following error:
TypeError: Error #1009: Cannot access a property or method of
a null object reference.
at loadCorrect_fla::MainTimeline/clip1()
I am obviously missing the point here, but how am I doing
this wrong?
Kind Regards,

Want to display a .bmp file in reports

Hello there
I am trying to display a .bmp file on reports which I think is simple.the main problem is that After making changes to report we transfer the report file to Unix and then generate the report in unix and print it and in that process the report stops printing.
Thanks in advance.
Jha

make sure SOURCE FILENAME is valid in your LINK FILE pointing to the image.bmp
Report compiles nicely even with wrong source filename, only when opening layout editor an error message will appear.

Tranferring Display Data on an Agilent DSO6014L to a .BMP file

Hello,
I'm able to read the DSO6014L Scope Display Data into a .bmp file, but I can't open it. Windows say the file must be corrupted, or to large. My file is the the same size as the .bmp file that's saved to my memory stick on the scope. There's something different, but I not sure what it could be. Any ideas. Thanks.

Mal,
It looks like you are using the Write to Binary File VI, don't you want to use Write to Bitmap?

How to display a 16-bit bmp file

Hi,
i have a 16 bit BMP file available in a byte[] along with the BITMAPINFO information. how to display this in Java.
i was able to find the code for displaying the 8-bit/24-bit BMP file in Javaworld :Java Tip 43 .
Pls provide pointers to sample/example code if available.

Try JAI it supports 8, 16, and 32 bit image data types.

Why java only can display GIF file not jpeg and BMP ??

Did anyone know why java only can display GIF file not in jpeg and BMP ?? This is because the quality of GIS is not as good as Jpeg and BMP
any code to load the display process ??
thx guys !!!

you can do jpegs but im not sure about bmps.
The only thing ive noticed is that java cant support transparent jpegs, only transparent gifs

Cfdocument - using cf7 - displaying .bmp & .tiff files

I'm using CF7's cfdocument tag (with no hope of upgrading to
CF8 anytime soon). I'm generating PDFs and not able to display .bmp
or .tiff files in the PDF. This was a known issue in this version.
-Has there been a fix, hotfix, or scheduled fix?
-Is there a workaround?
Thanks -

You might take a look at iText. It is what cfdocument uses
behind the scenes. It is not as simple as using cfdocument, but it
should be possible.

.bmp files do not show as icons in the event library - I am having to convert them to .jpg to achieve a display

Although .bmp files are to some extent supported, I find that on importing them they do not show as icons in the event library. I am having to convernt them to .jpg files to produce this result. Am I doing something wrongly, or is this the experience of others as well?

Yes - I've posted one of the files to Dropbox and it appears perfectly in picture form on my IPad. So it seems there is nothing wrong with the files. I'm even more puzzled now! I'll try to upload a smaller (less than 2mb) file here. The files I am using in the project, which is a kind of family history using stills, are a complete mix of types - tif, jpg, Canon raw(cr2), psd and bmp. Some, including, I suspect, many of the .bmps are scans from old prints, as this one.

Preview doesn't display bmp image

Using Bootcamp, I saved a BMP image file of a windows screenshot. I can view the screenshot with Tiger & Preview properly, but when I open the file with Leopard & Preview, the entire image is blank except for the windows image resize buttons in the top right corner.
Using Leopard and Quicktime, I can view the image. Also I can display the image properly using Microsoft Word on Leopard. I cannot see the image when I insert it into Pages on Leopard.
Why is the BMP file viewable with only certain applications? Does Preview, under Leopard, no longer support BMP files?

I tried using the link you provided to report the problem to Apple, but it wouldn't log me in. Do you have to be a developer to use Bug Report? If so, perhaps a developer could confirm this as a problem, and report it.
I posted the offending BMP file to my iDisk account: http://idisk.mac.com/rush1-Public
Problem: On a Leopard system the BMP is not displayed properly using Preview or Pages, but it is viewable using QuickTime or MSWord.

Why the value of 24bit bmp file read by the labview different from the original

when i use labview to read a bmp file,it looks just fine,but the the pixel value is dfferent from the original,how it changed,can i change it back

right... Your "result" indicator is an I16, it goes from -32768 to 32767... so that's not enough, before the 2 for loops, just after the Integer to colour value VI you should place a convertion node to convert to i64 and also change you result display representation to i64.
See attached VI.
Hope this helps

Are GIF, BMP files not supported?

Are GIF, BMP formats not supported? When I hit the import button, GIF and BMP files are not displayed.
If I put a *.* into the File Name box, then those file types appear. If I select a BMP or GIF and attempt to import it, I get the message "no photos were found to import". I've searched the LR help files for terms GIF and BMP and found zero results. Anyone?

Supported files are the RAW formats, JPEG, TIFF, and PSD with maximum compatibility on during save. If I forgot one, someone will probably correct me. I'm pretty sure gif, bmp and png are not supported.
Which camera do you have that produces gifs and bmps?

Emailing .BMP Files

'Some' .BMP files that are emailed to me simply show up as an icon at the end of the message with 'filename.bmp' posted below it.
I thought that maybe it wasn't downloaded so I would refresh the email or click on it to try to get it to download but it doesn't change anything. I can't get it to display from the email. It doesn't seem to be a size issue.
Going into the mail from my computer I can detach the picture and transfer it over to the iPhone through sync and view it without a problem. Any ideas on what we are doing wrong?

You were right again.
Seems this also helped answer my earlier incompatibility issue too. Looks like the iTunes software converts all pictures to .JPG when you load them onto your iPhone. Pictures that I have in my sync folder have been converted to .JPG when I select them to mail out to someone else. It's also quite picky about the exact format of the .JPG incoming from outside sources.
When I use an external email source to email myself a .BMP it does not display the picture, just an icon with the filename displayed below it.

Open .BMP files

Hi
On SP 2013
Having some BMP files ...now it opens up within IE
- how do I force it to open in Paint?

Issue
When you inserted an image, it was displayed as a thumbnail instead of a full image.
Solution
If the image you insert is not associated with the MS Paint application, it will not display correctly
To correct this issue, you will need to force a .bmp file extension association with MS Paint. Follow these steps:
In Windows Explorer, find a .bmp file and select it.
Right-click the .bmp file. Click Open With.
In the Open With dialog box, select MS Paint if it is in the list. If not, click Browse and search for the MS Paint application. It should be located in theC:\Windows\system32 directory.
Select the Always use this program to open the selected file check box.
Click OK.
Now the .bmp extension will be associated with MS Paint.
If you are not able to associate the .bmp extension with MS Paint, you can override the setting in the registry:
On the Start menu (Windows), click Run.
In the Run dialog box, enter regedit.
In the Registry Editor, locate the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.bmp
Right-click the (Default) entry. Click Modify.
In the Edit String dialog box, under Value data, enterPaint.Picture.
Click OK.

Why do JPEG files show up as BMP files when I email

Can someone help me send a full size JPEG Picture to a windows user without it changing it to a BMP file? I have chosen 'Always send windows-friendly attachments' and chosen 'Full Size', but it comes across as a .BMP file instead of JPEG.
Please help

If the person is using Yahoo on the other end they have to view your attachments by clicking on the "search shortcuts" and "my attachments". Then they will see the attachments as jpgs and have an option to download them. I am not sure what is happening because jpegs that I send by editing them in Adobe Photoshop Elements and dragging into mail attach in Yahoo normally.
Yahoo may be using bmp files to display the files when the actual file is actually a jpeg.
