Saving image without encoding

Hi,
I'm writing an appliaction that reads jpg files from local file system, resize them and write to disk. During this process most time is taken by encoding bitmap data to jpeg file format. I'm wondering if it's possible to write bitmap data to file without encoding it. Is it really necessary to encode jpg data again as jpg data? or is there any way to do resizing really fast?

My bad, it's pretty obvious that when I have bitmap data it's no longer stored as jpeg data and I can't save it as jpeg on disk.
My problem was solved by very efficient 3rd party jpeg encoding library: http://segfaultlabs.com/devlogs/alchemy-asynchronous-jpeg-encoding.
Currently I'm trying to compile it's latest version because the version I have now has some memory leaks. Wish me luck

Saving image without bits loss/change

hi there,
I was trying to save an Image (which i created myself with MemoryImageSource, and proper bit manipulation where red bits hold some characters, very important)and then i saved the image to jpeg by by using BufferedImage and com.sun.image.codec pacakage...its very important that when i read back the saved image, the bits the pixels array are the same as they had been created....but i found them changing...though image looks almost similar....can anybody out there help me how can i recover the same bits in Image pixel array or save it properly using some other technique, so that when i read the image the bits are not changed???
helps would be appreciated a lot..and your name would appear in my software's about dialog..that's a deal..plz help...

What codec were you using.
You want one that has "lossless" compression.
i.e. GIF, TIFF, TGA, BMP, etc.
JPEG has "lossy compression" although as someone mentioned you may be able to call a method to force it to be lossless.

How to see all image file types when saving images without selecting "all files"

Hallo, and thank you fom reading.
I am a person who saves a lot of images online in different folders with different names like G - 456 or F - 35.
I have been using firefox 10.0.2 for a long time because of a bug (I guess) that made it easier to save images.
When I saved an image it would always show me all the image files in any folder I wanted to save it, and that way making it easier for me to save files with the right names.
Now with the newer firefox (currently 19.0) whenever I try to save a JPEG I only see the JPEG files in the folder and only way to see the others is by selecting "save as type" all files, but with this I also see all the files that are not images.
This used to save me a lot of trouble and a bit of time but I dont see anything in the options menu that can help me. Is there a way to recreate this function?
Thank you for your time.

I suspect this is a Windows problem. I am surmising the FilePicker uses the Operating System or Desktop facilities. Does Windows 7 offer any other file categories like ''images'' ?
I do not normally use Windows 7, but may the option depend upon the directory being an indexed one, I ask after finding this thread ''Bring File types tab back'' [http://www.windows7taskforce.com/view/819]
This question is a duplicate of [/questions/951764]
Normally I would lock the duplicate question, but in this instance I will leave it open as it is unanswered and someone may give a better reply.

Saved image displays differently outside Photoshop

When I save an image I've been working on in Photoshop, then open the saved file outside Photoshop, the image looks quite different than it does inside Photoshop, much drabber and less saturated. I have both Photoshop and the display program set to sRGB. I figure that I should have consistency within the monitor, whether it's calibrated or not. I'm sure I'm missing something basic here. I'd appreciate any help here, because my prints wind up drab, too. Many thanks!

I overlooked one switch in the Save dialog. Now the images display correctly.
Can you be more specific, please?
Were you saving images without a color profile before, and some application(s) in your system were displaying them improperly?
Problem is, in that case one wouldn't really expect to see the kind of difference you describe unless your document profile really wasn't sRGB IEC61966-2.1.
Is it possible you're editing your images in the Adobe RGB 1998 color space? That could happen if you're opening images through Camera Raw, as the color space it's set to deliver is configured separately (via the link at the bottom-center of the Camera Raw dialog) from the Photoshop defaults.
By the way, if you don't already know, you can easily set the status block in the lower-left of the Photoshop window to show you the color space of your current document:

Saving a image without a background

I did the tutorial on Removing Image Backgrounds with
Fireworks. That works great, but I don't know how to save a image
without a background. I am trying to save it for a website. I have
Fireworks 8.0. I tried to save it as a Alpha Transparency GIF file
, but the image is poor. I don't know the correct way of saving
this.
Any help would be greatly appreciated.

Official JPEG specs does not allow any transparency at all,
so save your
time and quit trying it. GIF only support limited colors (up
to 256), one
of that can be assigned as "transparent". So when FW exports
GIF from a
source file that have any partial transparency, it "premixes"
any partial
transparent color of source with "matte" color. In case the
latter
correspond to average color of your page background, and your
page
background is not too wild and colorful, and you are not
using too wide
partially transparent stuff, it normally work well.
Among the image formats common on the Web, only PNG provides
true partial
transparency. Alas, IE still does not correctly understand
that part of
PNG specs that was set years ago. So if you definitely
positevely can't
live without transparency things that are available in GIFs,
PNG plus
specific CSS and\or Javascript trics is the only way to go.
However, I'd
personally make sure I can't live with old limited GIFs
before going that
way.

Why do the file extensions (.jpg .gif .png) no longer appear when I click on a previously saved image to use that image's file name (particularly important when saving a series of images using the same root name)?

I save a lot of images using firefox, often times from a large batch or series of images. It used to be that I would click on a previously saved image and the entire file name including the file extension (i.e. image_example.jpg) would appear in the "save as" line. Now when I click on a previously saved file, the file name appears without the file extension (i.e. image_example). Which means I have to manually type .jpg every time. For a large collection of images that I am hoping to use the same root file name and then add chronological numbers at the end, this has become incredibly frustrating, especially as it is a previously unnecessary task.
I am using a new Macbook Pro and maybe there's something Apple related to this...? It did not happen on my old PowerBook G4. I have file extensions turned on in System Preferences.
It should be noted that I have searched high and low and have even gone into the Apple Genius Bar where they were just confused as I was and of course ended by urging me to use Safari (shocker!) as it has all kinds of new extensions and bells and whistles. I seriously feel alone on an island with this dumb, hard to google problem. Thanks so much for any help anyone out there might have.
I mean: is this as simple as changing a setting in about:config?
Your assistance is greatly appreciated.

Thanks for your response Mylenium, however like I mentioned multiple times, I did change all of my trackpad/scrolling settings in system preferences. And if I wanted to use a normal mouse (or a tablet), I would've gotten an iMac instead of a MacBook Pro. I travel often and work all over the place, not always with access to a decently sized workspace that would be required for using a mouse or tablet.

How to resize large images without losing quality

Hello I have an image that I am trying to use as an email. Right now it is 2108 pixels. And for an email it should be 600 px. I created this image in illustrator as vectors and type.
Whenever I go into image size and i change it to be 600 pixels it gets extremely blurry. I have also tried converting this to a smart object... doesnt work. How do I resize my large image to be smaller without losing quality???

here is an example sceenshot of the opening dialog (.ai opened directly in Photoshop)
your illustrator vector should be rastered sharp at 100% actual Pixels in Photoshop
that is where you want to evaluate sharpness in Photoshop...
then File> Save for Web & Devices (and drag that saved file icon into an open web browser)
still no joy, embed your saved image here using the forum's camera icon...

N96 capturing but not saving images

Hi,
I've had an N96 for ages without issue but recently it has stopped saving images.
Camera works fine, can take photos and they display on the screen as captured but then, unlike before, they are not automatically saved.
Have checked memory space - loads left
Restored camera settings - no change
Have checked other folders and "all photos" rather than just gallery - still no sign of latest image(s)
Any help..?

Rob, the option to retain the original Raw file (in this case CR2) is in conversion to DNG done from the Library module, not to conversions done during importation when Copy as DNG is selected, because in this case the original remains on the card.
CDPhoto, if, on the Import page, you select Copy instead of Copy as DNG, your files on the hard disc will be CR2s. If your really do want them converted to DNG, in the right side panel select File Handling/Make a Second Copy To: and designate a location. The second copy will be CR2.

Saving Images to disk

I'm going to be making some graph Images, and I'm curious about saving them to disk. I've considered using Quicktime for Java, because quicktime supports so many image types and I need this versatility. The main problem is that, either way, I don't know how to save an Image to a file.
Any pointers would be much appreciated: websites, sample code using QTJava for saving images, etc.

Hi Xander
I think u want to convert the image ( which u draw as graph)into gif or jpge formate for this purpose u can use ACME
Gif/jpge encoder it is free ware (and it is writen in pure java)for converting image into gif/jpg formate and u can save it into ur hard disk
U can down the encode from www.acme.com
and use for encoding the image
just down lodad the packae and put that package in the current directory and import the package as
import Acme.JPM.Encoders.*;
in ur class where u encode the image
and for encoding the image here is the sample code
FileOutputStream out= null;
try{
File fc=new File("gif/" + "testgif"+".gif");
fc.createNewFile();
out = new FileOutputStream(fc);
}catch(IOException e){System.out.println("Gif Directory not Found");}
try{
GifEncoder encoder = new GifEncoder(image,out,true);
encoder.encode();
} catch(IOException e){System.out.println("File can't be created");}
I think this will help u

Newly saved images not showing in Library

When using LR 2, I export to PS CS3 to make some final corrections. I save these final images as both a PSD and JPG. When first using LR 2, the newly saved images were showing in the Library>Folders section immediately (without having to synchronize). I was making some preference changes recently I must have changed something that I didn't intend, because now the only way I can get the saved images to display is to synchronize. Anyone know what I need to change back to get my images to immediately show in the Folders (which also allows them to show in the grid and film strip) again?

This is discussed in excruciating detail in this thread:

Saving image to a folder not working on azure

I am saving image
files to a folder in my application and saving its path in database . Image uploads working fine when I am running locally
and its path is also storing.When I deployed it on azure it
gives an error that " An error occurred while processing your request ". I have two tables in my database . First one where text is saved is working fine on azure but image upload thrown this error.
I am using this code
to upload
image and its works fine when I am running locally. Need help ?

Hi,
Have you made any progress ?
May I ask what application is it that you are running ? You mentioned that it works locally but not when deploying to Azure. Have you checked the connections strings?
If you are still having any difficulty in understanding the code, perhaps you could post it on the below blog.

Data type for Saving Image in SQL database

Hi,
Which is the best way for saving images in the database? Filestream or Varbinary(max)?. Will the Varbinary max comsume much space or it will only take the actual size of the data?

I've used FILETABLE for storing images in SQL 2012
You can configure it to have transact and non transact access if you want
