How to maintain high resolution of exported images

I am working with iphoto 5.0.4. When trying to export (share>export) an image as a 'Full Size' image (3264 x 2448 4.5 MB) to the desktop it appears at that size with 300 dpi resolution. However if I export the same file as 'Scale image as no larger than:' the resolution remains 300 dpi but the size is reduced to 2.4 MB while the dimensions remain the same. And finally if any cropping is performed or if I resize the dimensions of the image, the exported image will reflect the altered size but also the dpi is reduced to 72. What gives? Does that mean that the printed version will only print at 72 dpi? How can I create a smaller size image and still maintain 300 dpi resolution? I thank you in advance for your help.

My first thought would be to remove the "Scale all objects ... " vi property. I have been using LabVIEW for 10+ years, and I always found that function to work very poorly. I never use it. At least you could try removing that setting and see if your problem goes away.

How see the original resolution of an image in Photoshop CC

I need to see the original resolution of a jpg, but when I go to Image size it is in much higher resolution. the jpg is about 600K which makes me suspect it is in 72 dpi, but when I open it in Photoshop CC it is about 23 MB and in 300 dpi. I need to know what the original is, and Image size is where I used to go to find out before I switched to CC. Does anyone know how I can check the original size and resolution?

I mean the size and resolution that the image was in when received it. I
had it as a jpg from my client, and have made no adjustments myself so
far. You are correct that I was just assuming that something must be
wrong. What puzzled me is that when I looked at the info about the
picture by right clicking on it, it was 600K, but when I opened it in
Photoshop it was 23 MB. What is the explanation for that?

How can you save keynote slides as high resolution (300 dpi) images?

Apparently there is a way to save powerpoint slides as 300 dpi images, with some finagling, but not the mac version. Does anyone know how to do this in keynote? Or is there a relativley easy way to do it with free/cheap software? I can increase the dpi in photoshop, but it doesn't produce crisp images for obvious reasons.

how can you save keynote slides as high resolution (300 dpi)
to save individual images from each slide in Keynote;     file > export > images > TIFF (for optimum quality)
You are using the wrong terminology to describe creating an image file
- dpi ( meaning dots per inch ) is the measurement used in printing to create the number of print dots per inch that will be deposited on to physical media like paper or film   This is done in the printer settings box of the print driver and is dependant on how the individual printer can print..
ppi ( meaning pixels per inch ) is the measurement you need to use when creating the number of pixels in a digital image file. You establish image resolution in Keynote using the inspector;
Keynote > inspector > document > slide size
I can increase the dpi in photoshop, but it doesn't produce crisp images for obvious reasons.
You can resample images in editing applications such as Photoshop or Painter but what you are doing is adding non image information to the image to increase pixel count, this is called noise. As you state this is not the procedure to use in your situation.

How to make high resolution image?

Hi All, I am in an urgent requirement where I have few .tif images. There size is very high. When I am uploading, there resolution is not good and they are automatically converted to jpg.
Can some one tell me "How to make this image high resolution image" Is there any setting or tips and tricks?
Reply immidiatly,

The original image is in MDM. I think what you may be getting confused by is the thumbnail view. The thumbnail view is automatically generated to give you just a low res view of the original from within MDM, likely for the sake of performance.
If you go to the Images table and right click on the image and select "view original" you will see that the high res original that was loaded is still there. You can also create image variants through the Console to generate other versions of the original to use for web or print. I don't think you can change the defaults used for the thumbnail.

How do I maintain high resolution of my Publisher file when I convert it to PDF?

How do I maintain the high resolution of my Publisher file when I convert it to PDF (I do not have access to a PostScript printer). Am I correct in understanding that the simple answer would be to convert the .pub file into a .ps file and then save this as a PDF? Which is no use to me because every time I try to convert my Publisher file to PostScript, the process fails because it is looking for connection to a PostScript printer. I need to send a high resolution (minimum 300dpi) PDF version of high resolution MSPublisher files to a commercial printer. And time is running out!

Hi,
The version set information and the tag hierarchy are stored within the catalog. It sounds as though you haven't brought over the catalog from your old computer.
The recommended way to transfer elements from one computer to a new one is to use the Backup catalog to CD, DVD or Hard Drive on your old system and then use Restore catalog from CD, DVD or Hard Drive on your new system. Is this how you did it?
That should have preserved your version sets.

How to use high resolution image as glyphs in icon editor?

i want to use a hiigh resolution image in icon editor . how do i use it?

Icons can be up to 32x32 px in size, so first you need to reduce the resolution of the image. Save as .bmp, .jpg or .png.
From the icon editor, select Edit -> Import Glyph from File... and choose your image. Done.

High Resolution HTML to Image Conversion

I am rendering a html file using JEditorPane and painting the pixels to a BufferedImage object. How can I make a higher resolution than 72 dpi.

    public static final double DPI = 72;
    public static final int WIDTH_PIXELS = (int) (WIDTH_INCHES * DPI);
    public static final int HEIGHT_PIXELS = (int) (HEIGHT_INCHES * DPI);
    public static void main(String[] args) throws FileNotFoundException,
            IOException {
        StringBuilder htmlCode = new StringBuilder();
        FileReader htmlFileReader = new FileReader("test.htm");
        BufferedReader htmlFileBufferedReader =
                new BufferedReader(htmlFileReader);
        String aLine;
        while ((aLine = htmlFileBufferedReader.readLine()) != null) {

        ImageIO.write(image, "png", new File("test.png"));
}How can I make this program to make a better resolution image?

I was profiling the application and found that iText was copying the whole image and running transparency checks for the 8.5 by 11 that I was doing at 72x4 dpi.
I found a way to do it more efficiently and it happens to take advantage of the vector text.
I used the PdfContentByte.createGraphicsShapes method to get a PDF Graphics2D object and I painted to that instead of painting to the java.awt.image. I did this in combination with disabling double buffering on the JEditorPane

How to maintain pixel size when exporting?

When exporting an edited image (ex: 20 MB) from Aperture to a desktop folder, I choose file>export>versions>jpeg original. When I open the exported image in the desktop folder (it opens in preview), the Tools/Inspector window says that the image is now only 2MB. This has not always happened. Can someone tell me what I might be doing or not doing that is causing this, or what settings I need to change?
Thank you.

golindy,
JPEG is a lossy format that relies on two ways of reducing the file size. The first is the lossy part that throws away data that is percieved to be unimportant for human vision, the resulting data is then further compressed losslessly using the same type of compression zip uses (this is why zipping a JPEG doesn't lead to further size reduction).
The more you throw away in the first part, the more likely the image is to suffer from 'compression artefacts'. The number you select on export determines how much data gets thrown away.
I don't know what '12' officially means for Apple, but from eyeballing files, it seems like it throws away pretty close to zero. So a file output with 12 is top quality.
Aperture has always worked the same way here, it hasn't changed during any update.
However, some things that may affect it are:
1) The effeciciency of the both compression algorithms seems to improve over time.
So a year ago, a 20 Mega Pixel image might compress down to a 5MB file using a quality setting of 10. Today that very same file may compress down to a 4MB file at quality 10. But it's important to note, the quality of the file will be the same, quality 10. All that has happened is the more efficient algorithm has allowed an extra 1MB of file space saving.
2) The raw converters periodically get improved with new rendering. One area that has continually improved in Apeture is noise supression and more natural sharpening.
These impact the first part of the compression process. A noisy image with harsh shapening will compress less than a clean image with more subtle sharpening. So better raw processing can also impact the exported size. Note, this one works in both directions, an improved conversion that resolves more details will output a larger file size, whereas an improved conversion that gives less noise will output a smaller file size.
So in your case, I think what was happening was you were not losing quality, just gaining file size efficiency, and now you have changed to quality 12, you are exploiting that file space saving by now outputting higher quality files.

How to get higher resolution previews in HDR Pro

I often make HDR images by exporting a bracket from lightroom into photoshop via right click>merge to HDR in photoshop. When the dialog comes up it is always a very low resolution preview. When I go to zoom in (cmd +) the resolution remains the same and I am zooming in on a pixelated image and the zoom is very limited. I am working from D3s files so there is plenty of resolution but it just doesn't show up in the preview. Is this simply the way it works or is there a way I can get a higher resolution preview. I'm not worried about rendering times either as I'm on a 8 core with 16gb or ram.
Thanks!

Liter Cola-
not sure if this is entirely what you want, but there are options in adjusting the preview for a 32bit HDR image. with a 32 bit image you can store the entire dynamic range of the HDR image:
"32‑bit Exposure
Option for adjusting the preview image for viewing 32‑bits-per-channel high dynamic range (HDR) images on your computer monitor. The slider is available only when the document window displays an HDR image."

What resolution to export images for projection?

I am trying to figure out what to set the tage parmaeters in Foto Magico for a slideshow to be projected. The only information I have about the projector is that "images are generally best at 1050 on thier longest side." Not very helpful. I have multiple dimensions - 4:3, square, etc. Just trying to figure out what to set the stage to so I can create an export parameter fpr my images at 1050 on longest side still have some black around. The only info I can find is HD resolution, which I don't want as it seems to be cropping my 4:3 images. Any thoughts or FM users?
thanks
Nancie

I agree it isn't very helpful...but that is all I have been told. Still trying to fiond out what the projector resolution is.
I am using a fit within...but everything I am reading about projectors tells me I should be able to use higher resolution for a projector. This is more of a Foto Magico question as it pertains to images coming from Aperture.
It is less the image resolution and more the slideshow settings I am trying to figure out. Maybe this is not the right place to post... Thanks Frank.

Need help : how to upload high resolution pictures

Hi, can anyone help me out with this. whenever I'm adding any pictuers to my site they looks kinda cr*py. the reason it because it's resizeing the image to a much smaller resolution.
question :
1. how do I upload a full res. image?
2. also if anybody knows how I can prevent people from downloading those images?
- thanks in advance

Maruf ~ Welcome to the discussions.
1. iWeb > Preferences > make sure +“Optimize images on import.”+ is deselected.

Another trick is to place a transparent, borderless Shape over your images.

How to find out resolution of an image?

Hi, all
Most common image formats (DIB, JPEG, PNG, TIFF and perhaps others) store the resolution of the image in pixels per inch (or other, similar units). I haven't found a way to find out this information using the Java libraries. Neither the AWT image classes nor the snazzy JAI classes seem to read & store this information, let alone make it public.
Is there a way to determine the resolution, short of poking through the header of the image data myself?
Thanks

Here's the solution (hopefully no one else ever has to track it down - the documentation is very well hidden by Sun).
                         ImageInputStream imageInput = ImageIO.createImageInputStream( fil );
                         Iterator it = ImageIO.getImageReaders(imageInput);
                         ImageReader reader = null;
                         while (it.hasNext()) {
                              reader = (ImageReader) it.next();
                              System.out.println(reader.toString());
                         reader.setInput(imageInput);
                         ImageReadParam param = reader.getDefaultReadParam();
                         BufferedImage bimg = reader.read(0, param);

Satellite P200D: How to get higher resolution with HDMI on external monitor

Hi,
i have problem with my notebook P200D. I want to use my book with extern LCD in resolution 1680x1050.
In analog connection i have reached this resolution, but the quality of the output is bad.
I see some waves on the screen of LCD. And colors are little bit different.
Notebook has hdmi output too, so I have bought hdmi/dvi cabel, which is working, but i have reached only the resolution of 1200x1020.
Cabel is signgle link, it exists dual link cabel, but i am not sure if this sloves my problem. I have read that the hdmi output in the Toshiba notebooks is only single link.
So i cant reached higher resolution than 1200x1020... Is it true?

Vlada I do not know what you mean with bad picture but if you can use the right resolution the picture must be simply brilliant. I am afraid you can not set the right resolution (1680 x 1050) and because of that you are not happy with analog connection.
About HDMI usage I can just say that I have tried to connect Qosmio G30 to my HD Ready LCD TV. I have just switched to the TV using FN+F5 key combination, checked graphic card settings and set it to the center. The picture was perfect and I didnt change resolution.
It is very interesting theme and I hope someone else will post own experiences.
Bye and good luck!

How to maintain the resolution of vi in different monitors

Hi friends,
Using Labview 8.0 i created an exe of the application. every vis i set the vi properties just like the attachment below. after installing the exe in a higher resolution monitor, when i open a sub window - 1st time its comming correctly but after stoping that sub window , if i open that subwindow once again than the resolution(size of the vi) of the window is changing.
in my application i want to take the print out of that window , 1st time print out is comming correctly but due to this resolution problem next time it taking 2 pages for printing.
please help me for that.

This behavior, and the ugly graph cursor display introduced in labview 8.0 is the two properties I dislike most in labview. The problem with your font is that Labview scales the font size depending on the settings selected in Display properties->Appearance->Font Size. If the defualt fonts are used. You find these windows settings by right clicking in the on an icon free area in your desktop. The font scaling will apply to the standard font types in Labview like application, system, and dialog. If the font settings are different in your development computer and the target computer, the front panel may look god on your computer, and totally messed up on the target computer. This will also occur if you have used some fancy fonts not installed on the target computer.
One solution to this problem modify the Labview ini file so both the target and development system have the same font settings. You will find more about it here http://wiki.lavag.org/LabVIEW_configuration_file/Fonts . A more cumbersome method is to not use application, system, or the dialog font style. If you are distributing an exe application you may create your own labview.ini file with the correct settings for the standard Labview fonts, and include it in the installer. Anyway I can not see why this "bug" not has been fixed. It has been like this at least since Labview 3.1. If you write a Word document you certainly not want the font size to change depending on the windows settings.
Here is the what I have inserted in the Labview ini on my computer. Is also include this as custom ini file then I make applications. The labview.ini is pure text
FPFont="Tahoma" 13
BDFont="Tahoma" 13
appFont="Tahoma" 13
dialogFont="Tahoma" 13
systemFont="Tahoma" 13
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

My first thought would be to remove the "Scale all objects ... " vi property. I have been using LabVIEW for 10+ years, and I always found that function to work very poorly. I never use it. At least you could try removing that setting and see if your problem goes away.
