Preview renders jpg incorrectly

I have one jpg image that gets rendered in preview, iPhoto or Aperture with a decidedly pink cast. However, when uploaded to my web server it renders correctly in Safari (but not if rendered by Safari locally). I have trashed previews prefs, done routine system maintenance, etc. without success. Any ideas?

Hi Robin
Not all .pdf's are created equal, and it is hard to analyse which application used to create .pdfs will open in other programs. Even within Acrobat, different versions will not be universally accessible in Preview which is known to not display some pdf's created in the later versions of Acrobat. I suppose you will just have to keep more than one .pdf viewer application handy to use when Preview fails.

Preview shrinks JPG's when added to PDF

I have an existing .PDF file, and if add a new page, then drop a .JPG file onto it, the picture shows very small with a large white border. In the Slideshow view it also appears very small.
If I open the .JPG on it's own in Preview, the picture shows as the correct size, but if I save it as a .PDF then re-open it has shrunk again. If I look at the info for the file, the dimensions are 612 * 792, whereas the .JPG file is 969 * 1331.
Why does Preview shrink .JPG pictures when added to an existing PDF, or saved as a new .PDF?

Edited to add - sorry, my description was slightly wrong.
If I open a single .JPG in a new Preview, and save it as a .PDF, the dimensions are fine. The issue only occurs if I try to add .JPG's to existing PDF's.
It also occurs if you use the shell to convert a single JPG image, i.e.
"/System/Library/Printers/Libraries/./convert" -f /users/me/downloads/cvg06300162.jpg -o /users/me/downloads/cvg06300162.pdf
- this gives the reduced size image as well.

Map Builder Preview rendering errors

I am having problems using Map Builder. I have wasted quite a bit of time trying to fix these problems assuming I was doing something wrong, or something was wrong with my data.
Error 1: I create a map using 2 themes. One theme is a geometry theme of topo edge primitives. The other is a topology theme of features built from those primitives. The geometry theme is assigned a red line style. The topology(feature) theme is assigned a blue line style. the geometry theme is listed first, to draw first. I expect to see the red overdrawn by the blue. The preview show red lines. When viewed in Acquis Data Editor, this map displays as expected (blue lines) and when a feature is removed (disassociated from the topo primitive) the underlying primitive shows up as red. When I stop and restart Map Builder, the preview rendering is as expected, blue on top.
Error 2: I create a map using 1 theme. This theme is a geometry theme of topo edge primitives. I assign node and edge styles. When I preview the map, the nodes (only one node per edge) are displayed at the center of the straight edges, at what appears to be mid-distance between the end points of the edges of the shaped edges (not on the edge), and in the center of rings created by edges that have the same start and end node. They look like they are attempting to be what ESRI calls label points. Again, when I view this map in Acquis Data Editor, the nodes show up on the ends of the edges where I usually tend to look for nodes to show up. Stopping and restarting Map Builder does not fix this rendering problem.
Are these known bugs and when can I expect to use the preview button reliably?

For the red line style, L.EDGE, the xml def is:
<?xml version="1.0" standalone="yes"?>
<svg height="1in" width="1in">
<desc/>
<g class="line" style="fill:#FF33FF;stroke-width:1.0">
<line class="base"/>
</g>
</svg>
For the blue line style, L.FEATURESTYLE, the xml def is:
<?xml version="1.0" standalone="yes"?>
<svg height="1in" width="1in">
<desc/>
<g class="line" style="fill:#3366FF;stroke-width:1.0">
<line class="base"/>
</g>
</svg>
For the geometry (edge primitive) theme, TOPO_EDGE, the xml def is:
<?xml version="1.0" standalone="yes"?>
<styling_rules>
<rule>
<features style="C.FACE"> </features>
</rule>
<rule>
<features style="M.NODE"> </features>
</rule>
<rule>
<features style="L.EDGE"> </features>
</rule>
</styling_rules>
For the topology(feature) theme, GLOBAL, the xml def is:
<?xml version="1.0" standalone="yes"?>
<styling_rules theme_type="topology" topology_name="MGF_TOPO">
<rule>
<features style="L.Featurestyle"> </features>
</rule>
</styling_rules>
For the base map, TEST2, the xml def is:
<?xml version="1.0" standalone="yes"?>
<map_definition>
<theme name="TOPO_EDGE"/>
<theme name="GLOBAL"/>
</map_definition>
As I said earlier, this does display blue lines after a restart of MapBuilder but upon first creating this map and themes, the initial display is red lines.
As to error 2: I understand now that Acquis probably does a specialty mapping of metatdata and uses the NODE$ table, applying the style definition for the edge theme (M.NODE) to display them.

Weird colours with QuickTime sources, broken preview renders & crash at exit (CS4)

Hi erveryone,
I have a strange problem in Premiere Pro CS4: Allmost all QuickTime MOV that I put in the timeline show weird, broken colours. At first I thought this was a problem with a specific codec, but I have now tried several codecs and pretty much every one shows up equally broken. The only codec that seems to work fine is the one that my Canon EOS 550D produces (1080p, H.264 I believe), but that one does not play smoothly (not that I would expect it to do on my machine). Strangely, H.264 in lower resolutions fails again. Other containers seem to be unaffected. Here is a screenshot of the effect:
Also, my preview renders (when rendering the effecs on the timeline) are similarly broken. They behave a bit erratically. Sometimes they are just black, showing nothing and sometimes they show a still frame of one of the previously viewed videos. Colours are messed up in a similar way, so I suspect a connection. Here is the same clip from the screenshow above, preview-rendered:
Also, upon exiting Premiere, it usually crashes. This is less of a problem, but still very weird behaviour.
Any ideas how I could solve this?
Infos about my system which might be of relevance:
Adobe Premiere Pro CS4 (education version)
Windows Vista 32bit (SP2, all current updates installed)
4GB RAM
Intel Core2 Duo
ATI X1300 Pro 256MB (with newest available driver)
QuickTime 7.6.6
The system has been freshly installed (from factory image - hence the older OS) so no malware or anything similar should mess anything up. Only software installed except the Creative Suite is Google Chrome.
On my laptop (Win7 64bit, Intel i5, no separate graphics card, same QT version) none of these problems appear.
Greetings,
Florian

I think I found the solution. Some further digging revealed that I did not have as previously assumed the latest driver for my graphics card installed. I was mislead because the manufacturer (Dell) did provide some updates, but not all of them (none in the past two years to be exact). I grabbed the newest driver kit from the ATI website and installed it. Strangely, the installer produced several errors and I get another error message at startup, but I think only the control software was affected and not the driver itself.
After some first tests, QuickTime movies behave as expected, the preview renders are working again and the crashes on exit are also gone. Yay!
Strange how much trouble a driver which is otherwise working perfectly can cause.

IMac crashes when previewing some jpg files

When I preview some jpg files using quicklook my Mac crashes, I get the same result when using get info on the same files. Other jpg files can be previewed without this problem. All jpg files open fine in Photoshop and can be saved with a different filename but the problem still exists with the new file. The files do not cause an issue on other iMacs. Does anyone know what could be causing this?

AE CS5 Preview rendering

When I render previews with the RAM preview button, I often get just a short sequence and then rendering stops automatically.
Now I thought this is due to RAM shortage.
Thing is, when I press the normal play button, I first get a realtime playback of the rendered part and then rendering is continued.
When I try the RAM preview button again, it just renders the same short sequence.
- Why can't the RAM preview button render more, while the the normal play button can?
- Why do preview renders often disappear when I try to render some more with the RAM preview button?
I find myself pressing the preview render button over and over, with very unpredictable outcome of what will happen: rendering extra material or deleting the existing preview and render another part. Is there any way to take control over what RAM preview does?

Thanks, this helps in understanding a bit what happens.

Ideal Preview rendering szize?

I'm confused about the ideal preview rendering size. My monitor res is 1152x864. I rendered the previews at 1640 or whatever it is, and my 130 GB files collection produces an 18 GB library. This seems huge.
Do I need the previews rendered at that size, given my monitor res? I thought the LR produces 1:1 previews when needes.
Guidance please!
Thanks!
Reid

So what about this idea?
Why not make all those previews easily accessible from outside LR? They could be named the same as the images they refer to and be stored in a corresponding folder structure. Why that? To be able to use them in other applications without having to open LR and export jpegs first! I'll happily set aside enough disk space even for 1:1 jpeg renderings as previews. (Sounds exactly like what Aperture already does ;-)

Preview rendering stops prematurely : Why?

Hello.
I am using a large photo (3072 x 2304) and animating the anchor point to create the pan and zoom effect between two keyframes.
The comp is set at:
1440 x 1080 (1.33)
29.97fps
The preview rendering stops prematurely. What are normally the reasons for this?
Is the photo too big?
Any tips would be appreciated.
Simon

What do you mean by "prematurely"? There's only so much frames one can squeeze into physical RAM at full res... Lower the comp resolution to Half or Quarter to extend the preview.

BLOB column -- no preview for jpg file

Hi,
I'm trying to create something close to the sample application with some other products. I have a table with BLOB column for the products jpg files. However, I have encountered the following challenge: the preview is not working.
http://i39.tinypic.com/2vtbn90.png
Can someone please advise?

Well that explains the problem. The url NEEDS to be a viable url to an image -- a procedure needs to be called to (in essence) spit out the blob to a mime-type of jpeg so the browser can display it. Although there are several ways to achieve this -- since you basically see it "working in one place but not another", take a look at how the working image's URL is generated on the page where it's working.. APEX offers an item type that can display an image, but you can also use PLSQL code to insert such in the rendered output anywhere. If none of this helps, there are many hits via google that discuss all of this in the detail you'll need.

Can I turn Lightroom previews into jpgs?

I recently lost my original raw (CR2) files for a set of photos. They were imported and edited in lightroom 4.1. I still have the lightroom catalog but the photo previews are occompanied by the warning "The file name "#####.cr2" is offline or missing". I am aware they are missing, the only version of the photos I still have is the LR preview. I am wondering if anyone knows of a way to extract the image information in a lightroom preview and save it as a jpg. (Not including doing a screen capture of the preview).

If you don't mind the colors being off, then the Adobe solution John Beardy linked to above may suffice (no icc profile assigned means colors will usually be interpreted incorrectly).
If you want the colors to look right, then use PreviewExporter instead (proper icc profile assigned):

When I add my composition to the Adobe Media Encoder from After Effects, it renders out incorrectly?

Why is it that when I add my composition directly from after effects to the adobe media encoder, it renders out of the adobe media encoder incorrectly? By that I mean the video comes out a little scrambled- parts of it overlap other parts. Is this an issue with 'dynamic link'? Did I do something wrong? I'm working in CC.

I also don't understand what you are saying. What do you mean by "parts of it overlap other parts"? A screen shot might help.
What were your render settings in AME? (Format, Codec, data rate, etc.)
What is in your AE comp? If footage, tell us what format, codec, etc. Tell us what effects were used too.
What exact version number of AE CC are you using?

Very Slow preview rendering for lightroom 5 on import

I am seeing very very slow rendering of preview images only when using the import function in lightroom 5. By slow, I mean for a shoot of 60 shots in raw, it could take 30 minutes before I can preview them all in the pane to see which ones I want to actually import. This was not an issue with lightroom 4. It is not an issue when using lightroom. Previews are fast there, even for images I've never pulled up before.
My hardware is a PC, with an intell i7 chip, and 16 gig of memory. My nvidia graphics card has the latest drivers.
I've seen a few others reporting this issue, so I'm trying to log it as a bug. Even though the dial up support text on the adobe lightroom says available 24/7, it now plays a voice recording that says only available m-f.
Brad

I'm having the same problem using Windows 7 (64b). I just took a shoot over the weekend for a significant birthday event. Now I can't load the photos. The work-around doesn't work as the program freezes before I get the chance to select the camera under "files".
I recently upgraded from 3.6 to 5 as I was also noticing a slowdown in the import function. That turned out to be a bad move I think. I also deliberately cleaned up the CF card and removed all my video recordings, as this seems to be reported as part of the problem, but to no avail.
This seems to be a pretty major bug to have in a major release that's been around for a while now, that I'm expected to pay for, and no sign of a resolution to date!

Lightroom preview and JPG color difference.

I'm a Photographer. Using Windows Vista and a brand new Dell 24" HC LCD monitor. Freshly calibrated with a MonacoOPTIX calibration kit. The profile generated is my default monitor profile. After calibration, I looked at some of my past photographic work and the colors looked very saturated to me. And the images all looked a bit brighter as well. I was working in an uncalibrated environment before so I figured thats why my pictures looked different. I shoot in RAW (Canon) and I always (and still do) export all of my work as sRGB.
Yesterday I was working on a personal image and noticed my preview in Lightroom looks a bit different than the output in JPG. I verified my settings and I am outputting to sRGB. I'm expecting my preview and and the JPG to match almost exactly.
See the screenshot here: http://lifesharephoto.smugmug.com/photos/256400141_Qy7np-L-1.jpg
Notice the web version is much brighter and more staurated?
Why would that be?

Lou, you are using a non-managed browser. No matter how much you calibrate, it will not show you correct color, even if you use sRGB. This is because your monitor's gamut will differ slightly from sRGB. IE7 is not color managed, even though Microsoft promised it would be a long time ago. Currently only Safari is color managed. Firefox 3.0 beta can color manage if you enable it in the settings. There is unfortunately nothing you can do about it and you have to realize that even if you do everything right, your audience will see different colors. They will all cluster around what you saw in Lightroom though and you should absolutely not trust your IE7 display, even if you calibrate. Only your monitor has that specific response. Other people will see more saturated greens, or more saturated blues, or the opposite. There is no predicting. It will all cluster more or less around sRGB though.

Problems Rendering Jpg/Png

I'm working on a project where we have tiff images and we break them into the individual pages, then we save those pages into memory streams in order to convert them into byte arrays so we can put that in a datatable column and bind that table to a report that has a OLE blob field that renders the image.
The problem I'm have is that in less than 1% of images the report fails to render the image and throw the following error:
Error in file tempReportPath.rpt: The request could not be submitted for background processing
I have analyzed the error and it only happens when the image is saved in the memory Stream and byte array as a compressed format: JPG/PNG/ Etc. Saving the image as a bitmap does not produce this problem, but the bitmap memory footprint makes it unusable for this project.
See code below.
Public Shared Function GetPicturesBytes(ByVal FileFullName As String) As Byte()()
        If Not IO.File.Exists(FileFullName) Then Return Nothing
        Dim tiff As Image = Image.FromFile(FileFullName)
        Dim dimension As New Imaging.FrameDimension(tiff.FrameDimensionsList(0))
        Dim frames As Integer = tiff.GetFrameCount(dimension)
        Dim Result(frames - 1)() As Byte
        For index As Integer = 0 To frames - 1
            tiff.SelectActiveFrame(dimension, index)
            Dim ms As New MemoryStream()
            tiff.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
            Result(index) = ms.ToArray()
            ms.Dispose()
        Next
       'This way because the file remains locked until the Image is disposed!!!
        tiff.Dispose()
        Return Result
    End Function
   Private Shared Function GetImgTbl(ByVal doc As DataTable, ByVal MRN As String, ByVal patienName As String, ByVal refId As Integer) As DataTable
        Dim imgTbl As New DSDocs.DocsDataTable()
        For Each rw As DataRow In doc.Rows 'wrap.Documents.Rows
            Dim docs()() As Byte = GetPicturesBytes(docFullName)
            If IsNothing(docs) Then
                imgTbl.AddDocsRow(Nothing, (Doc not found!!!),more,Data)
                Continue For
            Else
                For index As Integer = 0 To docs.Length - 1
                    imgTbl.AddDocsRow(docs(index), other,table,data)
                Next
            End If
        Next

Hi;
You don't mention which version of Crystal Reports you are using, or if you have installed the latest service packs.
We saw a similar issue recently, and our findings were:
- Crystal Reports 2008 with Service Pack 2 seems to handle images better than other versions
- Bitmap (BMP) files seem to work better than JPGs

Macbook pro retina 15 inch running Yosemite extremely slow previews/rendering

Hello,
So I got the newest version of Macbook pro retina 15 inch (mid-2014) basic model with 16GB of RAM, updated the OS to Yosemite, got Adobe CC on board, was happy for a second until I tried to edit stuff in After Effects. Preview plays at 13 fps at best when rendering something basic as a shape going from one point to the other. If you add footage it is 7fps or something. Already tried some options that were suggested on other threads like disabling App Nap but so far nothing helped. Please help me out, I'm really getting frustrated because of this.
Also, it takes ages to render final comp form Premiere Pro as well.
