Weird behaviour of images in firefox 3

Hi all,
I have a problem with firefox 3 since it is compiled with the --enable-system-cairo option. here is a screenshot
when firefox 3 was in unstable I recompiled it without the option to avoid the problem and it was ok.
disabling the option now with PKGBUILD and the other build files from [extra] doesn't solve the problem.
I have cairo package up-to-date from [extra] .
any advice?
thanks

I know this probably doesn't really help, but I do know one of the big changes in ff3 was the way it handles images. They were trying to really speed up the image loading/display code. I noticed in a lot of the betas i got black images or partially black images (bars across the top of varying height). This progressively happened less and less as the beta releases progressed, but maybe this is a related problem?

[Solved] Firefox 3 betas give me some weird behaviour with images

I understand that there will be problems with beta software, however I seem to have memory issues with the firefox 2 series, so I thought I'd give the beta packages a try. I'm using the firefox-nightly package from AUR (firefox3b4), and I'm getting some weird behaviour. The same behaviour can be seen in all firefox 3 beta builds, however. It's hard to explain the problem, so here's a screenshot:
Notice that the image appears twice, once in the tab, and once in the tab toolbar next to the title of the tab. It looks like an attempted preview gone terribly wrong. Upon closing the tab, the tab toolbar shrinks down to the normal size and all is well. This happens with most images up to a certain size. Any one else experiencing this problem? Any suggestions? This is very annoying and I would like anyone's input on the problem.

Wow! This issue was solved in #archlinux by Nuked. Apparently I had some funky bits in my .mozilla directory. Removing it solved the problem. Remember kids, IRC is your friend. Anyone else experiencing weird stuff with their Firefox install should give this solution a try.

Strange behaviour writing images.

Hi All,
I am using the javax.imageio package to do (what I thought would be) simple image resizes on the server side. I am completely baffled by the following behaviour though:
* Images are resized correctly.
* When resized to be smaller than the original size, they are shown correctly in the browser.
* When resized to be larger than the original size, the browser shows an image of the correct dimensions but the bottom portion of the image is blank. The size of the blank portion is directly proportional to the size of the resize.
* When I get the servlet to write to a file instead of the ServletOutputStream, the image does not have the blank portion.
* When I get the servlet to write to a file, and then send the file to the ServletOutputStream the image does have the blank portion.
* The problem persists if I use an AffineTransform to do the scaling instead of using Image.getScaledInstance().
* No combination of flushing/closing/disposing resources seems to bring back the blank portion.
* Using a MediaTracker to wait for image operations to complete has no effect.
* Using Thread.sleep() to wait for image operations to complete has no effect.
* The problem persists regardless of whether I use ImageIO.write() or ImageWriter.write().
* Changing the response buffer size has no effect.
* ImageIO.setUseCache(false) has no influence.
* Both IE and Firefox show the blank portions.
* I think I am going crazy.
Here is the code which does the transform and sends the output (you don't see the declarations, but 'output' is just response.getOuputStream()):
                /* do the resize */
                transform = new AffineTransformOp
                    (AffineTransform.getScaleInstance(
                       ((double) width) / image.getWidth(),
                       ((double) height) / image.getHeight()),
                    AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
                scaledImage = transform.filter(image, null);
                /* write to a servlet output stream */
                i = ImageIO.getImageWritersByMIMEType(file.getContentType());
                imStream = ImageIO.createImageOutputStream(output);
                imWriter = (ImageWriter) i.next();
                imWriter.setOutput(imStream);
                imWriter.write(scaledImage);
                /* free resources */
                imWriter.dispose();
                output.flush();If anybody has any suggestions, I'm all ears!
Roger

* I think I am going crazy.Not crazy... just stupid:
response.setContentLength((int) file.getSize());I was setting the content length to the size of the original image.

Last night suddenly when I right-click-view-images in firefox, they appear centered and against a black background. It's usually meant to be a white background and the image appearing at top left. How to revert it?

I'm having trouble with something in firefox, it's quite minor but still bugs me. Last night suddenly when I right-click-view-images in firefox, they appear centered and against a black background. It's usually meant to be a white background and the image appearing at top left. I can't remember what I did to change this if it's my fault; if someone knows how to revert it I'd be thankful.

cor-el : thanks for the pointers! I wish the solution isn't an add-on every time ... if such long-standing behaviour is going to change, the least that could be done is put in an about:config option to get back the old behaviour.

Roundness / Residual - weird behaviour

Hi,
I've been experimenting to understand "roundness" in Find Circular Edge - which seems to be the residual from "circle fit". I noticed some weird behaviour, and to understand it, I wrote a program that scales the width of a "perfect" circle from 0.5 to 1.5.
I expected some glitches, jumps,.. due to discretization, rounding,.. etc, but then I stumbled upon behaviour that makes no sense: When I detect a circle that is partly outside of the image, the roundness is suddenly at very low value.
To visulalize, I'm talking about such an image:
The roundness behaves like this:
I am not sure if it is just my vi (I'm attaching the example picture and the experimental vi), but can anyone explain this behaviour and give me some idea how to avoid it?
Thanks,
Birgit

The results of the "roundness" aka residual have a glitch once the detected circle is outside of the image.
Allow me to add a "normal" picture with a low residual of 0.17
High residual of 21,3
This behaviour sort of models how well the shape fits with the calculated circle.
And that's what I expect.
However, in the second the algorithm "finds" a circle that is outside of the image boundaries, the residual "jumps" and is suddenly very, very low, as if one had a shape that would fit with the calculated circle.
This, for example, has a residual of 0,27

[SOLVED] Weird behaviour after formatting USB installation media

Hi, I have noticed this weird behaviour with USB drives I used to install Arch linux with. I format them using fdisk and mkntfs but after replugging them in, the udevil daemon mounts them again as ARCH_2013...[something] and even the directory tree exists! This happens also when I use mkntfs without the -f flag (initializing with zeros). I also checked the other files in /dev/sd* in order to make sure that my drive does not appear twice, but there is only sda (my HD) and sdd (or sometimes sdb, sdc,...) which must be the USB drive, also according to dmesg.
Any ideas?
EDIT: I wrote something about not seeing any files when manually mounting but that was my bad, I only tried mounting /dev/sdb1 but mounting /dev/sdb brought me the same files as devmon showed.

I am assuming you used dd to write the image to the disk. You can use it to remove the contents of the disk as well.
You should make use of the arch wiki, it is quite helpful.
https://wiki.archlinux.org/index.php/US … tion_Media
You can use this to zero out the entire device:
# dd if=/dev/zero of=/dev/sdx bs=8M // x is the letter assigned to the usb drive. Be careful, The dd command is destructive.
It may take a while to zero out the entire disk, depending on the size. After that use fdisk/cfdisk or gdisk/cgdisk to create the partition table and partition.
To create the filesystem type, this one, ext4:
# mkfs.ext4 /dev/sdx // or create a vfat
then create the label:
# e2label /dev/sdx1 USB_STICK_LABEL
Use my suggestion as a last resort. Read the wiki, most of what I have said is in there anyway.

For the second time today images in Firefox have disappeared and, as I was Sincing two computers at the time, now they BOTH have the same problem.

Earlier today, the images on Firefox completely disappeared. Nothing I did fixed this issue; not restarting in Safe Mode, not disabling individual add-ons, nothing. No other browser was affected. After a little over an hour of this, the images suddenly came back with no changes from me. A little less than an hour ago, the same issue started happening, this time, though, I was using Sinc to transfer data to another computer and now both of them cannot display images in Firefox. Please fix this.

Make sure that you do not block (third-party) images, the permissions.default.image pref on the about:config page should be 1.
*http://kb.mozillazine.org/about:config
Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.
Make sure that you allow pages to choose their own colors.
*Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"
Note that these settings affect background images.
See also:
*http://kb.mozillazine.org/Website_colors_are_wrong
There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.

Error and weird behaviour in executable launch

Hello folks,
This post is regarding a weird behaviour i am experiencing with an executable i built.
LABVIEW version(Includes Runtime engine) LV2012 SP1 f3
DAQmx: 9.6.1
The behaviour is listed below in detail.
In a nutshell, the exectuable runs on the development computer but does not run on the Target computer. Also, Irresepctive of which PC i run the executable on, i cannot access the block diagram even after enabling debugging everywhere.
On the target PC, the app fires up but does not run further, no error codes appear on the screen, it's like the app freezes after firing up. And to add to the misery, i cannot access the block diagram to debug and know what's going on.
Also, I have tried including the dynamic vis to my build script. No bueno.
What I see on running the app is addressed below:
TARGET COMPUTER:
DAQmx 9.7 and LV2012 SP1 f4 RTE have been installed manually.
App does not run: No broken run button, the app launches but does nothing when the vi is run. No error messages.
The block diagram is still inaccessible, even after selecting the “Enable debugging” option in the build specifications.
DEVELOPMENT COMPUTER:
The app launches and runs perfectly.
The block diagram is still inaccessible, even after selecting the “Enable debugging” option in the build specifications.
DAQmx 9.7 and LV2012 SP1 f4 RTE were not installed as the app recognized the already installed Labview environment.
Additional steps that I have tried,
Created and ran only an executable on the target PC, the attempt was unsuccessful. The vi showed similar characteristics as mentioned above in the target PC section.
Created and ran an installer with additional install options(LV2012 f4 RTE and DAQmx 9.7)on the target PC, the attempt was again unsuccessful. The vi showed similar characteristics as mentioned above in the target PC section. No error messages.
Tried both the steps mentioned above on the development computer and the attempts were successful. .
To the best of my knowledge, I believe, the issue here is with the environment I am creating for the executable and the installer to run with/off of. After having carefully followed the installation procedure for the Run-Time Engine and the DAQmx drivers, I still do not know what I am missing.
Please advise.
Thanks guys,
RP.

Hey guys,
So, got the application to work. Almost.
The problem was that the executable was missing the hardware config from the Device.
Now, the new issue is as following:
The goal of the vi is to generate a report of the test conducted. So, the way the vi works is that, the second the vi is run, an empty word file is created with only the company logo,
Field headings, which are populated after the test is conducted.
The logo is a .jpg file, which has a relative path into the executable.
The field heading are String constants wired into a 'concatenate strings.vi' which are in turn wired to into the report generation vis.
What's happening is that when i run the app on the target pc, Only the logo appears on the word template. Even when i conduct the whole test and stop the vi, the results aren't populated in the word file. Which is a little weird.
Does any one know whats doing that?
Please refer to the attached word files.
Right - It is the file format desired.
Wrong - It is the file format achieved.
Please advise.
Thanks,
RP.

Brandeis U. switched to Gmail; since then I cannot display images in Firefox 3.6.13

Brandeis U. used to have its own email system (bmail), which linked to Firefox flawlessly. Brandeis switched to Gmail recently, which I do not like. After linking Firefox 3.6.13 to the Gmail, I can see my mail as text only, with urls linking to images. I found that in Gmail one has a choice of text only or images. You can chose "Always display images," but you have to do this for each site; however this does not carry over to Firefox. I have not been able to find the equivalent of "Always display images" in Firefox. Is there one? Also, after migrating to Gmail, when displaying old messages which used to show images in bmail, they now show text only.

Images in firefox won't load on android

Can you please update to Firefox 19?

Every time I right-click an image in Firefox 3.6.12 to view image size info it says "Unknown (not cached)". Any ideas on why this could be happening and how I can stop it? My OS is Ubuntu 10.10. If you need any more info let me know.

Can't show the image in Firefox

I have a problem to show the image in Firefox. They can show
in Explorer. Does anyone help me with this? You can visit the site:
www.norskbrannsikkerhet.no to see the problem.

The problem is the source for the image, you have
<img src="X:\CVS Norge\94 Prosjekter\945
Trading\SovReflex\Bilder\Thumbs\litenalarmpakke_it400.jpg"
alt="test"
border="0" align="top" id=""
onclick="MM_goToURL('parent','produkter/prodDetal.cfm?ProdID=21');return
document.MM_returnValue" />
So the source for the image is referring to a filepath, ie
X:\ rather than a
web path, so you`ll only see the image on your computer
connected to the X
drive. You need to change it to a web relative path, and then
it will work.

HTML Link -AS2 fine, AS3 weird behaviour

Hi Guys, I'm working on a project at the moment, and am
seeing weird behaviour with the way my swf handles html links
inside dynamic textboxes. When rendered as a AS2 file, the link
works on a release as expected. When its inside a AS3 file the link
will only work if the user right click and chooses 'open in new
window' was there a change in behaviour how AS3 handles these
links, or is there now an declaration needed to be made to allow
these link to have the old behaviour?
The project calls for xml data and embedded in that is a html
link. Originally I thought it might have been the way I'd formed
the xml so I tried with a hardcoded version instead (dynamic
textbox, add text -> highlight -> add link through properties
tab). But I still see the same behaviour between the as2 and as3
versions.
Any help would be greatly appreciated.
Cheers.

Actually, the ''href'' attribute is supposed to direct the browser to a new URL, etc., not run a script. Instead, use the ''onclick'' event attribute:
''<a onclick = “$('.div-feedback').fadeIn();”></a>''.
Happy coding!

Playing a series of jpeg images on Firefox (like a video)

We are having a problem playing a series of jpeg images on Firefox (like a video). It works perfectly on IE, Chrome and Safari.
Here you can see a demonstration of the problem: [http://www.youtube.com/watch?v=8tG0zuoMbLM http://www.youtube.com/watch?v=8tG0zuoMbLM]
Our code just loads one Jpeg after another. For some reason this causes Flickering with FF.
'''How to replicate the problem on our website'''
You can observe the problem by actually visiting our website. Please follow the link below (use firefox):
http://www.camba.tv/CameraView.aspx?c=fudraste
On this page select “Recorded Images” tab and then click “Play” below the image. Please increase play speed by clicking button with”>>” symbol. Once the images are playing you will notice a flicker in Firefox but the same page will not show flickering in Safari or chrome.

Export to QuickTime Conversion. In format set Image Sequence. In Options pick the format, TIFF would be better than JPEG, which a lossy format. Make folder. Save the images. Process in Photoshop or whatever. Import the images set to one frame or use QT Pro to convert it back to a movie.
