Image Resolution in Crystal Report

I am facing problem in image resolution when resizing big picture in crystal report.
Please help.

Thanks for your reply
The issue is the pictures (e.g. employee photos) are saved in Database as BLOB data type.
The report is loading employee photo into the report (e.g. employee card), but the loaded picture is coming up with much less quality than the original.

How do I change the image resolution of a photo?

Hi..,
     I am the beginner in Photoshop.
     I want to change one image resolution from 72 dpi to 300 dpi.
     So, I search and got one pdf for change the resolution of the image. In that they mention, take the "Printscreen" of the image and paste in the photoshop and change the mode(Index - flatten) and change resolution via the "Image -> image size -> Resolution".
     Like that i did, it changed correctly.
     After that I Open one already saved image file in Photoshop and do that same steps but the resolution was not changed.
So, now how to change that saved image resolution to 300 dpi...??
Regards.,
VISWA

Viswa,
To find the current resolution of your image, follow these steps:
With your image open in Photoshop, Image > Image Size (Like you've already done earlier).
Check the resolution as shown above. If it doesn't show 300, enter 300, hit OK and 'Save' your image.
Open the file and check again. If it still shows 72, post back with more details of the type of file you're trying to open in Photoshop and if possible, a screenshot so we can help.

Overprint Preview, RGB, Image Resolution Acrobat v9

I recently started using Acrobat 9. There is 2 things I'm looking in V9.
1- Overprint Preview
2- All image resolutions in a HiRes pdf. I see a custom check profile called "resolution of color & grayscale images is between..." but I want image resolution is ...
3- Flag any RGB images used.
ThankYou

I'm sorry what I mean if a pdf have 35 images I would to see the image resolution of all of them independently if they are 72 or 600 dpi.

Continuous tone image resolution lower than specified

The following message was posted in the incorrect forum; no legitimate solution to the problem was ever posted. I am re-posting it, as this is the same exact problem I am having, right down to the OS and version of Acrobat. Could someone please explain to me what this means and whether or not I should be concerned about it? I will also get two different kinds of results... one is a single number effective ppi on this error, such as 199, (which results in 200ppi if run through PitStop), and a two-number effective ppi, which we haven't been able to decipher, such as 501.357/179.55ppi (which should be a hi-resolution image).
Help?

> All text should export as vector, since it's all on a layer above any kind of image.
Is there any transparency in the text, though? If you float text over
an image with transparency, it MUST be exported as an image. If it is
floated over vector art with transparency, it MIGHT.
It's easy to assume that just because something is on top, it doesn't
ever need to be flattened. This is not in fact true.

You mean in its preflight? Unlikely, it isn't rocket science to
calculate ppi, so the numbers are probably right.
>
>Where is this "Continuous tone image resolution" turned on/off? Why is it important?
That's probably a reference to Distiller settings. I think we've
established that you aren't using Distiller.
>
>Is InDesignCS2 flattening to low transparency settings, even though my settings dictate high?
You'd probably need to ask in the InDesign forum. But bear in mind
that the flattener is free to use lower resolution if it thinks that
is all that is needed for particular effects.
Maybe you could reopen the PDF in Illustrator, and use that to select
the images in the flattened page. Might illuminate what is going on.

Finding image resolution in a PDF?

I am currently working to perform some maintenance for an app that formats and resizes documents, usually PDFs. The problem happens when certain files are uploaded with an unusually large image resolution (according to the Preflight Properties, 2222.222/2222.222 pt/in). The documents with this resolution come in with file sizes of 36"x24" and end up formatted to 8.5"x11". This leaves the text and a lot of information unreadable.
I am using Visual Basic with iTextSharp to interact with the PDFs that come in. I'm able to find the width and height in points of the document without issue. Finding the image's width/height pixel count is what is giving me fits.
Is there any way in iTextSharp that I can determine the pixel count for the width/height of a PDF Image, or am I heading down a dead end street here?
Thanks in advance for any help you can provide.

I hate to reply again, but I'm still stuck. I've been through the SDK and documentation and have had no luck finding anything to help solve this problem. I don't really need to extract the image per se, I just need to find the resolution of it. Could you possibly point me in a definitive direction in the SDK/Documentation that I could use? There are a couple examples that deal with Preflight but none dealing with the image in the PDF or its properties.
Thanks in advance.

Exported Raw Conversion Image Resolution and Assigning a Color Profile, etc

In Aperture 1.1, although I set the exported Raw conversion image resolution to 300 dpi in the preferences, it continues to come out at 72 dpi which is something of an inconvenience. Also, is it possible to assign a color profile to the "exported version" so that it is congruent to my PS CS2 color workspace (if that is what its called). Is this program capable of carrying out a conversion as a background operation? Finally, can the layout windows be configured so that they remember how they have been used in the past? Thanks.

Iatrogenic huh! Cool!
Anyway, I'm not real clear on what it is you are trying to accomplish. Despite your obvious vocabulary skills, there seems to be some disconnect relative to what you are trying to accomplish. You are right that "exporting a version" in Aperture is roughly equivalent to what happens in ACR when you "Open" a RAW image into Photoshop. In both cases you have, hopefully, already done the adjusting of parameters you want prior to "exporting", or "opening". When you "open" or "export" you wind up with an "image" composed of pixels, whereas in the RAW adjustment phase you are just working with a temporary thumbnail and a set of mathematical instructions. Big difference, I suppose is that when you "open" and image from ACR into CS2, the resulting image is truly just pixels and has not had a "file type" applied to the file yet, until you "save" it, while in Aperture, if you "export" a file to CS2, or to the desktop, you end up with the file type already applied. Presuming you "export" a 16 bit TIFF or PSD, there is no operational difference.
I could be wrong, but with the new Bayer Demosaicing algorithms in Aperture 1.1, and the Camera RAW adjustments, you should be able to come up with an adjusted image that is VERY close if not identical to one done in ACR, with the possible exception of lens abberation adjustment. I was very critical of the RAW adjustments in 1.0.1, but I am very happy with the capabilites in 1.1. That said, I think there is still some room for improvement in user friendliness of some of the adjustments such as Levels.

Check image resolution and color

Please let me know whether it is possible to get the image resolution and color used in a eps file.

Sashi

You can specify the resolution for exporting, for document etc but resolution of the raster objects can not be retrieved.
Color space of the raster object can be retrieved using the rasterItems : colorants or imageColorSpace properties

Image resolution for Photoshop EPS bitmaps

Greeting all,
I've posted about getting image resolution before and have a script we've been using with great success but I just learned from my operator that the script never returns the resolution for Photoshop EPS bitmap files.
I'm using .Graphics(1)..ActualPpi(0) and most times works just fine except for the Photoshop EPS bitmap files. Photoship color EPS, gray EPS and a bitmap TIF saved from Photoshop works just fine. Everything except Photoshop EPS bitmap.
I've tried using .EPSs(1).ActualPpi but that yields the same result.
Is there somethnig I'm missing (again)?
Many thanks,
Ken

Hi guys,
I offer the following approach to solve the problem:
var myDoc = app.activeDocument;
var myAllGraphics = myDoc.allGraphics;
var myGraphic = myAllGraphics[0];
var myLink = myGraphic.itemLink;
var myLinkXmp = myLink.linkXmp;
var myCreator = myLink.linkXmp.creator;
if (myCreator.indexOf("Adobe Illustrator") != -1) {
    alert("The first link was created in Illustrator");
else if (myCreator.indexOf("Adobe Photoshop") != -1) {
    try {
        var myXres = myGraphic.actualPpi[0];
        var myYres = myGraphic.actualPpi[1];
    catch(err) {
        if (err == "Error: A value is not available for this type of image.") {
            var myXres = myLinkXmp.getProperty("http://ns.adobe.com/tiff/1.0/", "tiff:XResolution");
            var myYres = myLinkXmp.getProperty("http://ns.adobe.com/tiff/1.0/", "tiff:YResolution");
    alert("Resolution of the first link:\nX: " + eval(myXres) + " ppi\nY: " + eval(myYres) + " ppi");

Scanning of Film Prints by Processing Labs - Image Resolution

I shoot a fair amount of film, in addition to digital, so I usually scan my own photos to be able to use the image editor. I've asked around to the run of the mill photo labs (wally world, costco, kmart, etc) about having my images output to picture CD and there appears to be quite a bit of difference in the image resolution and output format they offer. Many of them can't top my basic flatbed scanner.
anyone have any insight into this, or suggestions for where I might go to get a 5MP output image tif?
Most of the photo labs offer jpg at around 1600 x 1200
thanks!

My comment came about for 3 reasons:
1) I have come across quite a lot of people who either buy or save up for DSLRs who don't need them. They just think it's the only route to good pictures. The reality is that, in some cases, they never get a good pic because the cameras are too complex. The main thing is to be aware of the options.
2) For the last 15 years of film photography [I gave up film 3 years ago], I used SLRs. There really wasn't a choice. I started out with a bag full of lenses, which I lugged around. I missed loads of pictures because I hadn't lugged it. In the latter few years I started using "super-zoom" lenses - 28-200 and then 28-300. The effect was that I just didn't need any other optics. I was still carrying a camera weighing about 1Kg, but that was an improvement.
3) For me, photography is about taking pictures. Period. I come across so many people who are obsessed with all the equipment. They buy all the mags and are always hankering after something new. I sometimes wonder if they ever take any pictures [other than all those "test shots"]. I've had the same digicam for 3 years. I might upgrade it soon, but I'm not in a hurry.

Wrong image resolution for TIF file

Under OSX 10.6.2, the image resolution using Preview application is wrong for FAX MultiPages TIFF files.
If I open up a file with this resolution:
Image size: 1728 x 1081 pixels
Image DPI: 204 x 98 pixels/inch
Color Model: Gray.
The image always show up all squeezed vertically which tells me the Preview application is not processing the DPI properly. When using the size menu from tools, it assumes the resolution is the same for vertical and horizontal which is wrong.
I'm unable to use the Preview application to read FAX TIFF files with the standard FAX resolution.
How do I open up a trouble ticket with Apple developers to fix this issue? I believe it's a software design issue assuming that all TIFF files use the same resolution for both horizontal and vertical DPI. The Preview application should be able to handle different DPI for horizontal and vertical resolution.
We're a small business and we are running the whole office with Mac Minis and iMac with a Mac Mini Server of course. We love it, but we have this annoying bug which I don't have any way to fix it.
Thank you,

Here's a sample of the tif file from our fax machine you can download:
http://www.hmnet.net/warp2/fax-standard.tif
Download the file on your desktop and try opening it. You will see the square at the bottom will look like a rectangle. With the right resolution, it should look like a square, not a rectangle.
If I open the file with Windows picture and fax viewer, the resolution is fine and the square looks like a square. But the same file on Windows with Quicktime fails to open and it complains about a corrupted file.
On my MAC, the file opens with Preview, but the resolution is wrong.
Maybe the FAX server is not formatting the TIFF file properly, but we can't fix that since there's no more support for it. But the Windows app is able to open it up with the right resolution. So maybe it's just some code change to do in the Preview app.

Low image resolution in ipad

I had the new iPad for 3 months now but recently when emailing photos taken with the iPad to friends has been changed from 1936x2592 to 240x320. I couldn't find any settings to change the image resolutions. I am not sure why the resolution is being compress while emailing to people.

Thanks for your reply
The issue is the pictures (e.g. employee photos) are saved in Database as BLOB data type.
The report is loading employee photo into the report (e.g. employee card), but the loaded picture is coming up with much less quality than the original.

Poor displayed image resolution?

I've just started using FormsCentral I've inserted an image created in PhotoShop and saved both as a jpg (600dpi) and as a png. But the displayed image resolution (in FormsCentral preview) for either format is terrible. What have I done wrong?

If the space the image is placed in is smaller then the image size then our servers scale it down to fit. The best thing to do is make sure the image is not wider than the page and not taller than the space. Also save it at a lower web dpi so we don't reprocess it on the server.
Hope that works for you.

How to change image resolution in oracle forms.

Hi Experts,
I am working on oracle forms 10g (Windows7 OS). Can we get the image resolution of an image item in oracle forms? Can we resize the image in terms of resolution?
I have a requirement where user can upload only 1280x720 size images. Either i have to validate the image resolution and give them a message saying 'Only 1280x720 size images are allowed' or simply i have to convert the image to be upload to 1280x720 size and save in the database. If someone could give the solution for the above problem that would be very much appreciated.
Thanks,
Pramod SR

1. You need to resample.
2. You can automate the process.
1.
Open one of the images.
Go to Image > Image Size
Set the units to Percent (100)
Change the resolution to 300 ppi (not cm!)
Make sure Resample is checked
2. automation
Test the above steps to make sure it works.
Record the steps as an action.
Make a droplet from the action.
Drag the folder with the images to the droplet.
