PDF Export reducing dpi on jpeg images

Using Pages to create a book manuscript to submit to createspace.com which I have successfully done in the past. However createspace's automated reviewer indicates that the first 2 jpegs in the pdf have been reduced to 144 dpi, although the images are 3264 by 2448 uncropped. Identical images later in the book were converted without the dpi reduction. I've tried both replacing the photos and creating the pdf using both the PRINT dialog with photopaper setting and export with best setting. It seems to be a bug within pages--- any suggestions on workarounds?

Since you could be talking about any version of Pages, but are having problems that are usually associated with Pages 5, let's assume that you are talking about Pages 5.
Have you tried exporting the book from Pages '09 instead?

PDF Export - How do I resample images for 25% print?

Using OSX 10.6 and CS3 504.
I've built 6x large format pages at 1885mm x 600mm that will be printed on an HP5500. Content includes text, images, and objects with fills/strokes etc. All images have been resampled in Photoshop to produce an effective resolution of around 150dpi for printing at full size.
My printer is going to do a test print for me, at 25% final size. He has asked for images to be no less than 100dpi for 100% output. He has asked for Generic CMYK so I'm using the PDFx1a2001 preset.
As recommended on here in a previous thread, I've placed each of 6x pages of the 100% PDF (75mb) into a new document and scaled each down to 25%.
I then export to PDFx1a2001 again, and the resulting PDF is 45mb.
My question is, how do I give him the most efficient file that will:
take ages to transfer to him
not be too large for him to process
give me good enough quality to see how things look.
Do I need to change the resample numbers in the PDF export dialog? Or should this be OK?
Many thanks.

You can print the original PDF to a PostScript file at 25% and run it through Distiller if you have it. But I would just export a 100% file with images at 25 ppi and have the printer scale down when printing.

Keynote PDF Export and Color Profile

I have some color trouble with the pdf-exports of keynote: the color that is shown in the pdf does not correpond with the one in the keynote file. The pdf has more ”milky” colors. Maybe it is a color profile thing. But what profile doese keynote use for the screen? Or does it convert rgb-colors to cmyk? Anyway, how to sync exactly keynote and pdf colors for screen presentations?

There are a few things you can try:
In the PDF export box there is an Image Quality dropdown, where you can choose Good, Better or Best. Which are you using?
Alternatively you can just output the file as a PDF using the Print function. Your profile says you are using Mac OS X 10.4 in which case, in the print window click on the PDF button and choose Compress PDF to output a smaller file.
If you have since moved up to 10.5, this option is no longer available by default, but there is an Automator action that restores it here : http://www.apple.com/downloads/macosx/automator/compresspdfworkflow.html
The other thing to check is whether your graphics are at the actual size you need them or if you have scaled down a big picture, for example. The PDF will still contain information for the full-size image.
Re-sizing them in something like Photoshop to the size you need first before placing them in the presentation may help.
Finally, if you have Acrobat (Pro, not just the reader) you can use the Reduce File Size option in the FIle menu to compress the PDF you get from Keynote.
Post back with how you get on.

Keynote pdf export

Hi I am creating a graphic intensive presentation in Keynote, and wish to export this to i-web for an upload. How do I reduce the size of the export as a PDF.

PDF exports look terrible - white lines in text

I have been u sing indesign for years and years all of the sudden my pdf exports look terrible. The images are pixelated and the text has white lines
in it.
I used these pdf previews for my clients and I certainly cant use what Im getting from INDD right now. I have no idea what happened to cuase this.
Wish I could show you but any ideas would be great.
The following text has no formatting on it yet there are pixelated white lines? help?
Thanks in advance.

Wow - thank you for all the responses. Yes it still happened with different fonts, different sizes of font etc... So I looked at my export settings and noticed that it was set to High Quality Print - Modified. I Switched it back to High Quality Print and it appear to have cleaned it up quite a bit.
Thank you all for your speedy responses.

Photoshop Elements Upload to Shutterfly using JPEG images

I am trying to upload my Photoshop Elements 12 photobook as separate JPEG images. When I export the photobook to JPEG images the center of the 2 page spread goes onto both the JPEG of the left and right side of the individual JPEGs. Does anyone know how to avoid this problem?

Error when exporting to pdf - cannot read a jpeg image, but I do not know which jpeg image.

I have created a document (A5) in Indesign cs6 with 116 pages. Because I would like to print the book I want to export it to pdf. Normally this is no problem for me, but now I got the following error: "Error encountered while reading JPEG image. Image may be damaged or incompatible. Resave the image with different settings and try again." This is quite annoying as my book contains 631 links of which most are .jpg. Does anyone know how I can find out which picture gives the error?
What is remarkable is the following. As it is a very large file InDesign automatically splitted it in subsections (with names like 'A5 V' or 'A5 V3'). To get closer to the problem I tried to export each subsection (all between 3 and 30 pages) to pdf. But somehow I managed to do this, so one might think that there is nothing wrong with the document at all. But when I try to expor the document as a whole again I still get this error about the JPEG image. It takes a couple of minutes (somewhere between 30 and 40% of the exporting) before I get the error.
Is there anything I should have tried which I forgot? I hope anyone can help me with this problem.

If you are able to export as sections it's almost certainly not actually a problem with the image, but a problem of not enough system resources to finish the job. This is not uncommon with large complex PDF exports.
Try rebooting, then immediately open ID and try the export again first thing. If it works, great. If not, you can combine your sections into a single PDF in Acrobat Pro.

Poor Image quality upon PDF export

hi,
issue: images lose quality when viewed in PDFs
i've searched/read these and other forums for the past few days and have tried just about every suggestion out there in order to get better quality images in my PDFs and nothing works.. it's as if everyone is talking some theory without actually testing/proving what they're saying.
are pdfs inherently bad at handling raster images?
i have a few 800x1200 px renders (tiffs/jpgs) that i'd like to include in a PDF.. i'm using A4 landscape orientation because when viewed at full size on a 24" monitor, it's the size i'd like it to be (i'm not concerned with printing this pdf.. monitor only)
the images when view full size in the pdf are a bit smaller than viewing the original images full size however, the quality is a lot worse.
honestly, i'll try or retry your suggestions but at this point, i'm more/less looking for an explanation as to why this happens because from what i can tell, it's going to happen no matter what
gracias

Not sure what you are expecting.
well, i'm certainly expecting better quality than what i'm getting..
The jpg is contrasty and it is lower resolution than you need, but you did say that above. Which means I am not looking at what you are looking at.
The color space is srgb and the conversion from the tiff would have reduced the quality a little or a lot depending on your settings.
it doesn't matter if i use the original tiff or the jpg.. for all intents and purposes, let's forget i even have the tiff.. the jpg should look the same in the pdf (imo)
Did you print to pdf or Export? If you exported, did you use "Best" as your setting.
i've done all sort of methods.. but yeah, always at highest quality if said method allows such settings..
It has lost some contrast and is a little blurry. It looks to my eye like the degradation you get from setting the jpeg quality a little low.
well, no.. it has gone from something that is in focus to something that is out of focus.. if i open the jpg in photoshop and do a 'save as' jpg with the quality set to 3 (with 12 being best), i will get similar results as putting the jpg in a pdf.. (albeit, a different type of quality loss but just as bad)
you've seen the comparison but just in case someone else wants to look, check here:
http://homepage.mac.com/jeffhammond/Sites/imgs/origVSpdf.jpg
that's a screenshot showing the jpg on the right and the pdf output on the left (both viewed in preview)..
it's unacceptable.. but like i said earlier, i think this is an inherent aspect of pdfs and i'd settle for a decent explanation as to why it happens..
OSX has some very smart frameworks built in, which do make bitmaps displayed on screen in Cocoa apps look better than they should. Not exactly helpful if you simply want to see it unenhanced.
but still, if that's the case, why isn't osx doing the same thing to the pdf.. (and also, i highly doubt the actual quality of the image is being shown in the pdf but when i view the jpg, i'm being shown an enhanced view to the point of making an out-of-focus image being an in focus image.

Maximum Image Quality for PDF Export

I'm having a pretty big pain with some of my images, and I wanted to make sure that when i'm exporting my document to a PDF, I'm getting the very best resolution possible. I've attached a screenshot of the settings I'm using... are these the best settings I can set for getting the best resolution from my PDF
export?

First, the cost of printng isn't necessarily directly related to quality. There are too many factors such as full color and additional spot plates, the size of the run, and the size and type of the press to make any judgements based on price, not to mention the skill and standards of the printer. And then you still have many printers willing to do the same quality work at a variety of prices depending on location, market, and how busy they are. Kind of like making a genearlization about the price of a car.
@ Luke, setting downsampling to none will guarantee that all images are sent at full resolution, but that isn't necessarily a good thing. As already pointed out there is no advantage in sending more data than required to print the image. The OP has alread chosen ZIP compression, which is lossless, so he isn't introducing any jpeg artifacts, so all the downsampling is doing is setting a ceiling above which images will be downsampled. Images below that threshold will be sent at full res.

How to reduce the image size of a jpeg image?

How do I reduce the size of an iphoto jpeg image?

What do you mean by size? The dimensions? The File size?
There are options depending on exactly what you want to do and why you want to do it.
In general: these are options in the File -> Export dialogue. The Jpeg Quality setting refers to file size, the Size option refers to dimensions.

Bridge Exports Changes Resolution from 300 to 72 dpi, resizing my image

I like to use Bridge (CS5) to export my photographs for printing, and frequently I will use the Export feature to resize the images (e.g., 5x7 vs full size), but every time I export it recharacterizes the images as 72 dpi, vs the 300 dpi I prefer.
Consistent with some of the previous postings (~2 yrs ago) I have seen on this topic the exported images are now "sized" much bigger (29"x20" for what should have been ~5"x7"), and hence expectantly I haven't lost any resolution, but it's aggrevating to have the dpi changed.
Can anyone tell me how to export without having the dpi changed?
And while I'm at it, can anyone confirm that I'm not loosing image resolution?
Thanks so much!!

Can anyone tell me how to export without having the dpi changed?
Can't find any other settings to change and just having tested it I can confirm that it sets ppi (it is pixels per inch -ppi- for a digital file which is made from pixels and dots per inch -dpi- from the ink dots of a print ) to 72.
And while I'm at it, can anyone confirm that I'm not loosing image resolution?
You already stated yourself that you did not loose pixels, therefor the size of the files stays the same. It is just a mater of figures. 300 ppi means a larger concentration per inch and 72 pixels per inch means a smaller concentration of pixels per inch. Given the same amount of pixels for both settings this means a smaller image dimension for 300 ppi and a larger image dimension for the 72 ppi.
300 ppi is some 'magic' number from printed press, but it really depends on the need of the job related printing machine. If you have a small image and need to look closely it should have a larger concentration per inch to reflect its sharpness.
However theoretically you would almost have the same visible quality when printed on 72 at billboard sizes. That's because you always have a large distance between your eyes and the bill board. If you look closely you will see the dots (because the billboard is a product of ink dots…) but of course it is not meant to study at that close range.
The same is for judging sharpness on your computer. Ideally you do so at 100 % for correct judgement at real size pixels. But in reality there will be almost no situation you will study a print at that same distance
Any thoughts on why these would be different? And am I fretting over things unncessarily?
Only guesses, the use a different algorithm or calculation scheme, in my case I tried a Canon Raw (converted to DNG) without any ACR settings then the basics applied and found that Bridge export jpeg 11 creates larger files then using PS.
But there are some other concerns I have and that certainly would make me fretting in use of export module:
First of all I almost never use it, merely in this cases for testing, because using the menu tools give a shortcut to Photoshop / Batch and inhere I have created several dedicated resizing and resaving actions that also places the files in preset folders.
But with this small test I found out that
a: it changes ppi to 72 ppi, not a very big deal but I did not asked for it nor did I wanted it.
b: it converts my Adobe RGB color space to sRGB and I certainly did not want that without my explicit wish for this conversion, so this is more then a bit worrying to my concern.
c: it seems to apply a sharpness that I certainly did not want to happen without my knowledge, and this rules the use of the export module out completely.
Since I only tried a DNG file without settings or retouch/developing in Photoshop the jpeg generated by PS was not very sharp. This makes sense to me because I have set my basic ACR to apply sharpening only to preview. There are a lot of different sharpening theories around but I use one in PS itself. So I was a bit shocked to learn that the export module did all those for me unwanted and not adjustable settings putting me completely out of control…
So if you want to have full control about things happening under the hood yourself just start creating actions in PS, it is very easy to record an action and even more easier to play it. Instead of every time dragging files to export module and always recheck the image options (it seems to reset itself always to jpeg quality 8 on my system) only select the files you want to resize and choose menu tool / Photoshop Batch and select the wanted action. hit OK and your almost done, PS does the rest.
The great thing of the latest PS CS6 action pallet is the extension with a so called 'insert conditional' that let's you create an 'if - then else' action for both landscape and portrait resizing actions so you don't need the 'constrain to fit' or 'fit image' option. Just once create an action for both resizing dimensions and then create a new action with insert conditional. choose If image is landscape play action…. / else play action….
It is really a very productive way. I have a lot of actions (organized in sets for better overview) and even one that creates 4 different sizes in 4 different folders using 1 go in Bridge

How to insert a pdf or jpeg image into a blob column of a table

How to insert a pdf or jpeg image into a blob column of a table

Hi,
Try This
Loading an image into a BLOB column and displaying it via OAS
The steps are as follows:
Step 1.
Create a table to store the blobs:
create table blobs
( id varchar2(255),
blob_col blob
Step 2.
Create a logical directory in the database to the physical file system:
create or replace directory MY_FILES as 'c:\images';
Step 3.
Create a procedure to load the blobs from the file system using the logical
directory. The gif "aria.gif" must exist in c:\images.
create or replace procedure insert_img as
f_lob bfile;
b_lob blob;
begin
insert into blobs values ( 'MyGif', empty_blob() )
return blob_col into b_lob;
f_lob := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen(f_lob, dbms_lob.file_readonly);
dbms_lob.loadfromfile( b_lob, f_lob, dbms_lob.getlength(f_lob) );
dbms_lob.fileclose(f_lob);
commit;
end;
Step 4.
Create a procedure that is called via Oracle Application Server to display the
image.
create or replace procedure get_img as
vblob blob;
buffer raw(32000);
buffer_size integer := 32000;
offset integer := 1;
length number;
begin
owa_util.mime_header('image/gif');
select blob_col into vblob from blobs where id = 'MyGif';
length := dbms_lob.getlength(vblob);
while offset < length loop
dbms_lob.read(vblob, buffer_size, offset, buffer);
htp.prn(utl_raw.cast_to_varchar2(buffer));
offset := offset + buffer_size;
end loop;
exception
when others then
htp.p(sqlerrm);
end;
Step 5.
Use the PL/SQL cartridge to call the get_img procedure
OR
Create that procedure as a function and invoke it within your PL/SQL code to
place the images appropriately on your HTML page via the PL/SQL toolkit.
from a html form
1. Create an HTML form where the image field will be <input type="file">. You also
need the file MIME type .
2. Create a procedure receiving the form parameters. The file field will be a Varchar2
parameter, because you receive the image path not the image itself.
3. Insert the image file into table using "Create directory NAME as IMAGE_PATH" and
then use "Insert into TABLE (consecutive, BLOB_OBJECT, MIME_OBJECT) values (sequence.nextval,
EMPTY_BLOB(), 'GIF' or 'JPEG') returning BLOB_OBJECT, consecutive into variable_blob,
variable_consecutive.
4. Load the file into table using:
dbms_lob.loadfromfile(variable_blob, variable_file_name, dbms_lob.getlength(variable_file_name));
dbms_lob.fileclose(variable_file_name);
commit.

Converting a pdf document to a jpeg image C#

HI There,
How can I convert a pdf document to a jpeg image using c sharp? I need to do this on a web application. If someone can help me out with some code that would be great.
Sean - thanks in advance

The information provided by Aandi is unfortunately out of date. The Adobe PDF Library is obtained through Datalogics and has a JNI, Java, and .NET interface available. Additionally while the Adobe PDF Library with the .NET interface would provide the functionality you seek it is overkill.
PDF2IMG from Datalogics has a COM component available that can be accessed via C# to convert PDF to most image formats.

CS3: PDF-Export Transparency Issue when Image-Links are missing

I have a Layout with a transparent Frame on the top most Layer. For this Workflow-Step I do not have access to the original Image-Links, so I guess that all I see are the embedded Preview-Pictures and InDesign reports that all Object-Links are missing.
If I export this Layout as JPG, the resulting JPG looks like the WYSIWYG in InDesign, which is suitable for this workflow-step. However when I export as pdf, the Frame is not transparent anymore. Instead it is filled with white color and covers the rest of the Layout. In Adobe Reader I can actually select the wrongly covered Picture at the border of the frame and copy&paste it somewhere and it looks fine.
When I provide the original Frame-Picture and repair the missing Link in InDesign, PDF-Export works fine.
I have installed & updated InDesign on a new Mac OS X 10.4.11, so all settings should be default.
Transparency Blend Space is set to CMYK. I tried all default PDF-Export Profiles and tried a lot of different settings in the pdf-export dialogue including different PDF-File-Versions, Simulate Overprint on/off, Color-Conversion disabled, disabling Picture-Compression and much more. I also tried to Print a PS-File and then use the Distiller: same result.
I use Adobe InDesign CS3 V 5.0.2 and tried Adobe Reader 8.1.2 and Adobe Acrobat Pro 8 to display.
Any Ideas?

Transparency flattening REQUIRES having access to the high-resolution images to get good results. One of the slogans I teach printers is "Fatten before you flatten." Meaning, replace the low-res images with high-res images.

CRXIR2 image from blob field and some fonts not displaying in PDF export

I used CRXIR2 developer edition to create a report linked to a SQL 2000 database table. There is a blob field containing a JPG image that is different for each record in the table. I am using VB.NET code with ASP.NET 2.0 to programmatically change the temp file to a local folder for easy cleanup, open this crystal report with the 11.5.3700.0 version of the assemblies, set the datasource to a DataTable extracted from the DB, and then export to a PDF file.
The code for creating the PDF is:
        Dim TempRoot As String = MapPath(".") & "\temp\"
        Dim oldTmp As String = System.Environment.GetEnvironmentVariable("TMP")
        System.Environment.SetEnvironmentVariable("TMP", TempRoot)
        Dim objReport As New ReportDocument()
        objReport.Load(MapPath(".") & "\CReports\" & ReportName)
        For lnX As Integer = 0 To objReport.Database.Tables.Count - 1
                objReport.Database.Tables(lnX).SetDataSource(resultTable)
        Next
        Dim objDestinationOptions As New DiskFileDestinationOptions()
        Dim objExportOptions As New ExportOptions()
        Dim objFormatTypeOptions As New CrystalDecisions.Shared.PdfRtfWordFormatOptions()
        Dim pdfName As String = "test.pdf"
        objDestinationOptions.DiskFileName = MapPath(".") & "\temp\" & pdfName
        objExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat
        objExportOptions.ExportDestinationType = ExportDestinationType.DiskFile
        objExportOptions.ExportDestinationOptions = objDestinationOptions
        objReport.Export(objExportOptions)
        objReport.Dispose()
        System.Environment.SetEnvironmentVariable("TMP", oldTmp)
When I run the site locally in VS2008, everything works fine and a PDF contains the graph and all the fonts are correct.
However, when I run the exact same site from a web server running IIS6, the PDF generated does not have the image, and some of the fonts are substituted (all of the necessary fonts are installed on the IIS server).
Please help!

Hi Don,
I am able to see the image and export from the CR Designer on my machine running XP. However, I installed the designer on our IIS server running Server 2003, and the image does not show in the designer preview on that machine.
I found another forum thread that you are involved in (1902383) that seems to be dealing with this exact issue, and it looks like there may not be a resolution.
I am going to try a different route - instead of pulling in the SQL Image field directly, I am going to write it out to a temporary file and pull it in by altering the graphic location of the picture object in the report.
I'll let you know how that works.
Pete
