• Best way to save the images streaming from the web to device?

  We have an app to browse a catalog this content of stream of a web server. There is an image for each product, some in JPG format and some in PNG format. Our server is fast and reliable, so everything worked without problems so far, but we would like to give users the ability to save data on their device, so they don't have to listen to every time. I've only worked with before SharedObjects, which are capped at 100kb and will not help in this situation.

  What would be the best approach for storage of images and keeping them is crushed in the updates? Save an uncompressed Bitmap uses too much storage space. Adobe's JPEGEncoder class is completely useless because it takes 10 to 30 seconds to save an image of medium size on a typical device. Also, he does not sense of re - encode jpg files, and we must preserve transparency in png.

  At the moment we are using a loader to retrieve images and using loader.content to access the image data in the code. Is it possible to save the image file in its original local format when downloaded with a charger? We would like the images stored in the application data and not available through the gallery. With regard to the registration of the data for each product (price, description, etc.), the built-in SQLite support would be enough or should we create our own files?

  Thanks for the tips!

  Ah, I got it. Existing files are checked as indicated cmholden. If the image is not stored locally, we use URLStream to load the image file on the web. We can then save the file directly via the ByteArray to the URLStream and then use our code existing loader to load the ByteArray even as a DisplayObject. I was worried there would be some downturn app to save the files, but the change in performance is negligible and of course once the images are saved on the device they charge a lot more quickly the next time the application is run!

• Photoshop is change the name of the images imported from Lightroom.

  Today I sent a batch of photos in Photoshop since Lightroom (via the Edit menu selection in). When I finished the work in Photoshop I selected SAVE, as I always do, only the photos are back in Lightroom under a new file name instead of the same name (as always in the past) with a suffix of .psd. It changed to Photoshop CC I'm not aware of. Both programs are up to date.

  In preferences, in the 'External editing' tab, you can specify a file name template that controls what filename is Photoshop.

• How can I remove the originals, I don't like to take when importing from a SD card?

  Hi all

  Just installed LR3 with Santa. Have been going through the videos and the Lightroom_3_Help PDF and PDF of Lightroom-GettingStarted_Lo but I can not understand how to remove files from the gitgo simply importing from an SD card or from my HARD drive (files already moved on the HARD drive but not yet slaughtered or imported into LR3). I was hoping that I could, at the LIBRARY, just r/c on a file that isn't obviously useful to keep and just remove it so I mustn't do it later. Looks like I could, thus, be able to focus more on the shots requiring a change.

  Also, need suggestions as to how I would like to import my files using the DNG, Copy, Move, or Add. First off, I'm not a pro at work but am an occasional serious amateur. I'm picky and I like things look the first time and I like options.  The pix already on my HARD drive is in the IMAGES folder. those that are imported from the SD card are transferred to the PHOTO folder. I have, in the past, moved the verssions transformed to another DESTINATION folder - now I still have the originals and I've dealt with copies to show and share.

  I understand that LR3 don't ND edition but I guess that if I don't keep a DNG so anytime I want a JPEG or PNG image that I open LR3 to make a. Since I've been taking a few hundred pix per year (although this will change with my new D5000) I won't load to the top of my HARD drive any time soon. So, is there a way I can make a DNG file, keep the original RAW or JPEG file AND save a JPEG or PNG copy turned in my DESTINATION folder in one swell foop?

  Thanks in advance,

  Phil in San Diego

  There is no need to delete the source; Select the photos you want to copy the source into your library and apply metadata and keywords that apply to all, then back up the photos that are now in the library, and then only have to format the SD card. Using this method, you will never have to worry about the photos of the source should be deleted, you simply focus on which those that are imported. Your also always make sure to have two copies of your work at all times and consider make a third copy you should kee off site to maximize the availability of your data disaster (and don't foget the catalogue Lightroom itself!).

• I use LR 6.5 on an iMAC. Files RAF Fuji originally, I imported from an SD card worked and exported in the form of PSD and then after saving the files on an external hard drive RAF erased from Lightroom. I now want to import some RAF b HD files

  I use LR 6.5 on an iMAC. Files RAF Fuji originally, I imported from an SD card worked and exported in the form of PSD and then after saving the files on an external hard drive RAF erased from Lightroom. I now have to import some RAF of the HD files but LR shows them as dazed out and said that they have already been imported when I hover over the thumbnail. I have this problem when importing files in the same HD Canon CR2, and who have been treated exactly the same. Anyone got a clue as to why this is happening? Thanks, Phil

  Hi Phil,

  If Lightroom then reads these as duplicate files, it shows that they are already present in your Lightroom Catalog.

  You can search by file name and check if the image is present in your library.

• I can edit a picture from iPhoto in EP 11. How to save the image in iPhoto library?

  I found the useful help pages in the Forum.  I can now automatically open an image (which is stored in iPhoto) in PE11 to change.  And the editing is very good.  Where I am bamboozled is: How do I save the image changed in the iPhoto library?  Seems to be to save the image somewhere, modified but I'm not, and it does not seem to be saved in my iPhoto library.
  Someone knows what to do?

• VBAI 2012 "save the image calibrated to the file" issue

  Hello

  Under the State of 'Calibrate Image', 'Save the image calibrated to the file' option does not work correctly.

  With the exception of the type 'Point of Distance' of the calibration, the new image is ever recorded. I checked the calibration image .cal2 in the folder \ProgramData\National Instruments\Vision AI\Calibration Builder, each iteration the meta-data are updated but not the image.

  I have a camera calibrated with a grid (see picture) and using the model of the distortion. Working remotely can sometimes change and I need to take a recalibration. This step should be as simple as possible. Example: put a model calibration in the field of view, then press a button recalibrate.

  The problem mentioned above, it is impossible. Whenever I have to manually go into the choice of the State of the Image calibrate and update the calibration image myself. Otherwise, calibration is recalculated from the original image which is not best suited for the new working distance.

  Is there an easy way to make VBAI save a new image of calibration with each iteration?

  Or is it something that I did not understand this option 'save image calibrated to the file?

• Why you need to save the images in photomerge panorama?

  Hello.

  I don't understand why with the new version of the Photomerge panorama when I select "create panorama" the program asks me to save the images prior to their merger.

  In addition I don' t understand what foto I must record and in which format?  (all the? in JPG? in PSD?)

  Even after doing this (Save ALL images to merge as a JPG-copy) I can't go forward.

  Thank you to anyone to help me.

  See this other post.

  Panoramas - Error Message: the Documents must be registered before they can be merged

  The problem only arises with the images in a vertical position.

  It didn't happen with older versions of items, so I don't think that it can not be solved.

  You don't have any extra work if you work from the organizer and you export your files to the correct resolution.

• How to save the image of the host?

  Hello

  Anyone know of a way to save the image virtual host? I can't find any document about it.

  I installed ESXI 4 and installed the converter and converted a P2V in the ESXI4 host. I connect on the ESXI host from the web browser and it starts fine, but I can't find anything on the backup I just create the image.

  Any advice will be grateful.

  When you select the host from this view, look to the right and you will see the summary tabs, virtual machines, Performance, etc. and is the desired Configuration.

• Save the file imported into oracle directory

  Hello.
  I'm on a project where I need to import a CSV (imported by using app APEX 4.0.1) in a specific oracle (complete and functional) table, and then save the file imported to the server.
  This part of the savings on the disk where I have my doubts.
  I know that I can use utl_file to write the file to an Oracle Directory, but that I have to open the blob (file) twice: one for import to the table and the other to write to the disk - because I want to just save if the file is successfully imported.
  
  Is there a more direct way to do this?
  
  Thank you

  NO, you could use an external program to C and then to write a wrapper for an Oracle to store the BLOB in an Oracle Directory. : http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:6379798216275

• Save the Image as it goes back to the same place, even after re-booting

  After re-booting, save the image as must go to the main menu and I picked where to save the image. Currently, image tries to be registered on the same site as an earlier session. Is there a solution for this.

  Thanks jscher2000
  You said much more skillfully I did my question. I want indeed the last directory deleted to stop, so the first suggested location is the default folder, i.e. Downloads.Your suggested fix worked well and I thank you. I'm a little disappointed with Firefox that he had to go so deeply into their program for this fix. But I appreciate your expertise. See you soon.

• Save the image does not remember last location recorded for Firefox 9

  Just updated for FF9. I'm is not just disappointed, but which are checked the the bug that causes save slot to remember where it was recorded the last file of individual sites instead of just where the last file has been saved to has not been set. Why is this? How can be addressed?

  For example, I have save a folder A Motifake image and an image of ihasahotdog to folder C. Then come back to Motifake and save a picture. Instead of folder C, save under opens to the folder instead of the folder C. I have direct save as to save the image in A file. The I'll go back to ihasahotdog, save a picture and instead of A folder, save under opens to folder C.

  This bug also occurs with all types of files, not just of images.

  The FF developers know that the "added functionality" that started with FF7 causing the FF remember the last download save the folder based on the domain in the URL instead of use the last folder saved on annoys many users both directly and by the lack of preference to toggle. Yet they will not fix it.

  Why they do that little matter how much a good idea, they think it is, most users hate it and do not want? And what is this B.S. "is under development"? They added in an updated version, why can't they get out as fast as it was added?

  Firefox 11 should be released about 12 weeks after the release of Firefox 9, so it should be in March.
