Strange lines in JPG export. Artifacts?

Hi guys,
I've been having a problem recently exporting files as jpgs. I have a template for my blog -- one for a horizontal image and one for two verticals. I export these as JPG high at 72ppi.
I've started seeing strange lines form on certain files. They're never in the same place twice and flipping anti-aliasing on and off doesn't change anything. I've created several different templates using different sizes and export resolutions and I'm still getting these lines. Any help would be appreciated.
I've included a link to the original file without the red circles.

The lines on my iPhone 2G are still there after it happend and after posting to this thread 3 months ago. There is no software solution for sure. It seems that, according to the following link:
http://www.modmyi.com/forums/general-iphone-chat/410391-grey-lines-iphone-displa y.html
2G iPhone users have to buy/install the entire assembly (glass, digitizer, LCD)
3G iPhone users can buy/install the LCD only.
Or make use of the warranty service...

Speckles in shadows AND strange lines in highlights

I've found that I get strange lines in highlights and intense constellations of speckles in shadows when changing treatment from colour to greyscale and back to colour in Lightroom 2.5. A reimported copy of the image will not display the effect. If I change nothing else, switching to library view makes the artifacts go away, back to develop and they reappear. If I change anything else, they are there to stay. The exported file includes the artifacts. My CPU is an Athlon XP (so no SSE2), OS is Windows XP SP3 32-bit. Images are from a Sony A700 fw v.4. Just thought I'd see if anyone else who wasn't on a PowerPC Mac is having these issues with this release as well?

Yes. At least one more non-Power PC user reported this.

JPG export preset in InDesign?

Hi all,
Is there a way to save my JPG export selections as a preset? I have to export JPGs of the same document for two different purposes and they have different export requirements. Is there a way to save my selections as a preset the same way I can save my PDF export selections as presets?
InDesign 7.0.4
Mac 10.6.8
Cheers,
Trish

I'm pretty sure it won't be your fault, but I don't seem to be able to fix it. Try this one but it exports the number of pages squared! For example a 4 page document gives you 16 jpegs, 5 = 25 and so on.
What am I doing wrong John? I added in this line: app.jpegExportPreferences.jpegExportRange = ExportRangeOrAllPages.EXPORT_ALL;
//Display a "choose folder" dialog box.
if(app.documents.length != 0){
var myFolder = Folder.selectDialog ("Choose a Folder");
if(myFolder != null){
myExportPages(myFolder);
else{
alert("Please open a document and try again.");
function myExportPages(myFolder){
var myFilePath, myPageName, myFile;
var myDocument = app.activeDocument;
var myDocumentName = myDocument.name;
var myDialog = app.dialogs.add({name:"ExportPages"});
with(myDialog.dialogColumns.add().dialogRows.add()){
staticTexts.add({staticLabel:"Base name:"});
var myBaseNameField = textEditboxes.add({editContents:myDocumentName,
minWidth:160});
var myResult = myDialog.show();
if(myResult == true){
//The name of the exported files will be the base name +
//the page name + ".jpeg".
var myBaseName = myBaseNameField.editContents;
//Remove the dialog box from memory.
myDialog.destroy();
//Generate a file path from the folder name, the base document name,
//page name.
for(var myCounter = 0; myCounter < myDocument.pages.length;
myCounter++){
myPageName = myDocument.pages.item(myCounter).name;
app.jpegExportPreferences.jpegExportRange = ExportRangeOrAllPages.EXPORT_ALL;
//Modify the following to change the Resolution. Enter a figure instead of 300
app.jpegExportPreferences.exportResolution = 300;
//Modify the following to change the colour space. the options are:
//JpegColorSpaceEnum.RGB
//JpegColorSpaceEnum.CMYK
//JpegColorSpaceEnum.GRAY
app.jpegExportPreferences.jpegColorSpace = JpegColorSpaceEnum.CMYK;
//Modify the following to change the jpeg quality. the options are:
//JPEGOptionsQuality.LOW
//JPEGOptionsQuality.MEDIUM
//JPEGOptionsQuality.HIGH

app.jpegExportPreferences.jpegQuality = JPEGOptionsQuality.MAXIMUM;
//Modify the following to change the Rendering Style. the options are:
//JPEGOptionsFormat.BASELINE_ENCODING
//JPEGOptionsFormat.PROGRESSIVE_ENCODING
app.jpegExportPreferences.jpegRenderingStyle = JPEGOptionsFormat.BASELINE_ENCODING;
//The name of the exported files will be the base name +

Extremely large jpg exported files - help!

I was previously loving LR3 - used the trial for a month, decided to buy it - had really no problems. The big issue for me is now the jpg export file sizes that are being created. I run all my photos through the develop module to adjust the basics as well as draw in masks, and previously I had no trouble exporting the files as jpg, with the limit of size at 600kb and resized to 960x640 (original photos from 5Dmk2 RAW).
Then I bought the license. From then on it seems that now whenever I do the same exact export it doesn't work! I also used to use the output quality slider and set that at 100% and would get around the same file sizes, but now I'm getting files 2-3x the size of the previous exports. All of the photos have minimal metadata (10 keywords or so, that's it) and the same metadata was present in the exports in the trial version.
Playing around with more export parameters and reading around on this forum led me to try and minimize exif data - this didn't even work - files could not meet the requirements or they still ended up 2-3x the size they used to be.
The interesting part is that when I would delete all development history and set the file back to the original pre-edited RAW and export there would be no problems!
Could it be possible that LR is adding the development data into the metadata that it is attaching to the photo??
This has completely shut down my photo workflow and really is making me regret buying this otherwise wonderful tool.

This data results from heavy use of the local adjustment brush. Choosing "Minimize Embedded Metadata" upon export really should solve this problem for you. Please try again specifying this option.
But then, by doing so, you lose any other metadata (keywords etc.) also. To have complete control on what metadata gets written into the JPEG upon export, you could use Jeffrey’s “Metadata Wrangler” Lightroom Plugin.
I noticed one strange thing within the XMP data in your JPEG:
The data seems to be formatted differently than what I see with JPEGs I export ("HasExtendedXMP"), which I don't know where it comes from.
For further investigation, would it be possible for you to upload the Raw file and the XMP file belonging to it to somewhere (e.g. www.yousendit.com) and post a link to it here?

Strange lines

I create tutorials for a company. Ever since I started using
Adobe Captivate 3 (over a year), strange lines appear in the
rendered version of certain screen shots. These lines only appear
in a consistent group of screen shots. I have tried every angle I
could think of to get rid of them including:
Exporting the existing backgrounds and inserting them into a
new project.
Taking new screen shots.
Importing the project into Flash 8.
Pulling out my hair.
Again, these lines do not appear in the project until I
render it into a flash file and run it.

Welcome to our community, Scoot
Have you tried the following? Right-click the slides
exhibiting the behavior and choose Properties. Then adjust the
Quality. Perhaps JPEG or something else.
Cheers... Rick

Serious Problem with Export Artifacts

Using 1.5.2 I just worked on about 50 nef images. Most were processed in Apeture, some I exported to CS2 and back. As I work images, little symbols appear in the little thumbnails, telling whether its a master or sometimes there's a couple of symbols in a black box in the thumbnail. They don't show in the actual previews. For some reason when I exported out of Aperture finished images, 1st as original sized Tiffs and then a follow jpg set these issues popped up.
1st: Tiffs all exported as PSD's inspite of selecting exoport as tiffs 16bit.
2nd and worse: Many of the psd files and jpgs exported the symbols and the black box from the thumbnails.
This has never happened before and is quite disasterous as I was exporting these to burn on to a dvd for a finished project for a client.
Any ideas? I don't want to have to go back and reprocess the images.
Let me add that I selected which versions I wanted to export from and selected them all at once and batched export as it were.
I'm going back and exporting individually and am still getting these artifacts.

Never seen anything like this Barry.
Snake oil would be to trash your plist and retry.
G.
Its wierd because it will save to Tiff 8 bit. Also, if I removed all adjusments it reverts to normal probabl because on the non-destructive editing. So I just removed all adjustments and re did a couple of them, stamped the metadata and it seems to be fine now.

JPGs exported from Lightroom 5.6 will not open in other applications

Recently I have noticed that jpgs exported from Lightroom 5.6 can not be opened in Canon DPP 3.14 and can not be resized using Image Resizer plugin. Both of these I use frequently.
I have seen mention of this issue re other applications also. Does anyone know if there is a solution?
I am using Windows 8.1 64bit. 5D Mark ii

This was an issue with 5.5 (the placement of some of the internal headers of the jpgs was changed and some other applications, including DPP, could not open them), but was corrected in 5.6. I just checked on it by exporting a jpg and opening it with no problem in DPP 3.14.15, Windows 7 x64. Are your jpgs old ones from LR 5.5?

Sporadic strange lines in my screen

It happens sometimes that strange lines appear in my screen for some miliseconds XD. It's a short time but it finishes being unconfortable.
I'm using xorg with xf86-video-intel, i've got direct rendering and i'm using the gnome desktop. Any idea?

i have the same problem. about a day after i got my ipod little lines appeared on the screen, when i have my ipod on it looks like i have little lines of water on the screen so it makes the pixles look messed up. i guess they must be sratches but i dont want a big protective case for my ipod. any suggestions?

Dotted line is not exported correctly form Indesign to pdf

My dotted lines do not export as exactly round dots but with kind of "erroded" outlines. Has anyone encountered the same problem yet? How can I solve it? I used the "export for high res print preset". Thanx!

With "manually", Bob meant you cannot do it in InDesign (which must make it as good as 'manual', in his opinion ).
Using Acrobat Pro, all you have to do is open the PDF and start the Forms Wizard. It's the top item under the Forms menu. You'll be amazed at how well it does:
All I did was start the wizard and hit "OK"!
(hey! that image was supposed to end up inbetween! jive editor showing a tantrum, again.)

Strange lines appearing behind itunes

I went away for the holidays, and when I got back I booted up my 2006 iMac. Today for the first time, there are strange lines appearing behind iTunes whenever it is open but not the active window. I tried quitting and restarting iTunes, but the lines come back. I wish I could upload a screen shot of what this looks like on my desktop, it's very weird. It does not happen behind any other program window. Only iTunes. The lines appear as if they are extensions of the iTunes window formatting, in line with the side bars, etc. Has anyone else experienced this? Any tips for getting it to quit?

I just wanted to add that I am also seeing the same problem: strange lines around the borders of the iTunes window. The most obvious ones are a set of four vertical lines running parallel to both sides of the iTunes window, although there are other strange bits as well, mostly around the top corners of the window, as well as a single thin horizontal line above the top of the iTunes window. These unusual lines started appearing "out of the blue" sometime in the past few weeks -- as in, not right after an update or any other configuration change to my mac... The only change I can say I did recently was to update to OS 10.6.6, although I know others who are running 10.6.6 and aren't having this issue with iTunes. I also wanted to add that in my case, I only see these strange lines when iTunes is the active window. Further to that, updating to iTunes 10.1.2 does not fix the problem, unfortunately.

How do I change the white background color in a b/w line drawing jpg?

How do I change the white background color in a b/w line drawing jpg?

Just put a Solid Color Layer atop it and set it to Blend Mode Multiply or

• invert Selection (cmd-I)
• create a black Solid Color Layer
• put whatever below that Layer

Strange lines on my screen

Recently I have noticed strange lines appearing on the screen of my MacBook Pro - they appear and disappear randomly. I have noticed it especially on and around icons, as well as around the edges of Finder windows. Today it escalated to the point where I couldn't see anything on the screen (see attached screenshot). My computer is about 3 years old and I haven't had any problems with it.
I just recently upgraded to Mavericks - could this have anything to do with it? The problem started shortly thereafter.
Please help!!

Multi-threaded JPG export

The slowest portion of my application is the conversion from a generated INDD file to JPEG. More CPU power seems to be the only solution at this point, but because IDS is single threaded, 3 of the cores on the server sit idle during this.
Is it possible to implement a plugin or Javascript script that exports each page in a separate thread, or similar, thus using all available cores during the export process?

Hi,
I think it is possible in InDesign 5 via "asynchronousExportFile". You can also create multiple server instances and let each instance generate a jpg export.

Strange lines in pages while browsing (Render errors?)

Strange lines that look like render errors show up while browsing, and seem to be triggered by moving the mouse & scrolling. I've also noticed that this problem seems to only occur when the browser is maximized. Rolling over links makes the link text pop ot from behind the lines.

hello, please try [[Upgrade your graphics drivers to use hardware acceleration and WebGL|updating your graphics driver]] - this should be the right link for your system: www.geforce.com/drivers/results/56378
or in case this doesn't solve the issue, disable hardware acceleration in ''firefox > options > advanced > general''.

Strange line on my homepage

Help. I can't get this strange line off my home page as it appears in Safari or any other browser. However, when it is open in iWeb, the line does not appear no matter what I do. Here is my url: http://web.mac.com/kerririchardson

It looks like iweb generated a different CSS for the Welcome page than other page.
You can fix that by changing the Welcome.css file, Welcome.css is located in Welcome_files folder.
Open it with a text editor and search for: graphicshape_styledefault
In that block, you see: *border: 1px #751b96 solid;*
You either remove it or change 1px --> 0px
