Impossible to modify Image size with Directshow

Hi!
  i'm using an IDS ueye USB camera with directshow.
With its own software and other Dierctshow softwares, i'm able to modify the size of the image and the frame rate of the camera.
Unfortunatelly, with MAX is impossible to change the size of the image.
I can only choose between few video mode by a ring control, such as "1024x768 RGB32 15.00fps","1024x768 RGB24 15.00fps,"1024x768 RGB8 15.00fps". No way to select a custom format.
With other directshow softwares i can change the FPS, Width and Heught parameters without any problems.
As you can see in the attached image, the value of the size are disabled.
I attach even the AMCap .ini files.
Can anyone help me?Is it a bug of Max?

grepponline,
This is a limitation of DirectShow. The subset of defined interfaces for controlling the camera is fixed and limited and does not include facilities for things such as changing the width and height directly, only via the list of video modes the driver exposes.
What you are seeing is that DirectShow provides facilities that a driver can provide a UI panel that can be opened to control things in their driver directly. It seems that IDS's driver has a custom panel for controlling those things you showed in your screenshot.
Now, in IMAQdx we made a conscious decision not to rely on the camera-vendor-specific UI popup. There are many reasons for this, but the main reason is that IMAQdx cannot interact programatically with those panels. One would have to call some function in IMAQdx and then a random window would have to pop up that the user would have to interact with. We would also have no way to store these settings in our camera file like all the other camera settings, since DirectShow leaves it vendor-defined how the driver is expected to store any changes you make in their UI. 
As you mentioned, it makes sense for customers writing software using IMAQdx to be able to write software once and use it with any camera IMAQdx supports. Any saved settings in MAX are applied when you open the camera. If we relied upon the vendor-specific UI panels we could not give this behavior.
I would suggest you encourage IDS to provide more options in their standardized supported video modes DirectShow interface if you are not finding a mode that matches what you want. The other option would be to move to a camera technology that is more flexible with regards to configuring the camera in a generic way, such as firewire or GiGE Vision.

  • Can you lock aspect ratio, define border and image size with automated BatchCropStraighten?

    Hello everybody,
    I need to crop and straighten a load of scanned rectangular stamps that will start as a single scanned image, and I want to lock the aspect ratio to 1:1, define the top border size (such that the the borders on the sides will be bigger than those top and bottom) and specify the output image size.
    Does anybody know if this is possible using the automates BatchCropStraighten function?
    Thanks,
    Paul

    I know of no BatchCropStraighten feature in Photoshop.  Photoshop has a Plugin CropPhotosAuto that you access through menu File>Automate>Crop and Straighten Photos.
    On my windows system its "C:\Program Files\Adobe\Adobe Photoshop CC 2014\Required\Plug-Ins\Automate\CropPhotosAuto.8li". This plug-in is designed to help you scan several image with a single scan. All the plug-in does is to look at the current active document looking for what appears to be a scanned image and to create an additional document that contain a straighten version of the image the size of the image. No files are created nothing is saved only one document is processed even if you had several scans open in Photoshop.  When the Plug-in ends the current active document is the last document the plugin created.
    You may be able to program a Photoshop script that would fit the create documents to some size then add canvas that would make all the documents have the same Aspect ratio and size. The borders added would be equally sizes on opposite sides top and bottom the same left and right the same.  However the image aspect ration inside the borders may vary.
    I created a fake scan with five simulated images. Not straight and not all rectangles  and duped the document so two would be open the used File>Automate>Crop and Straighten Photos when the process finished I spread out the document so you could see all that are open in this screen capture.

  • Maximum image size with createImage() in applet

    hi,
    I am making a simple Horizontal scrolling stocks ticker. I made an offscreen image with all the companies,prices etc on the image and just change the x position of the image. My problem is that when the data increases the applet fails to create the offscreen image.Giving the following error:

    When the image width goes above 32767 this error props up. Also even if the image size is less than 32767, while scrolling if mouse or any other window comes over the applet the whole applet starts behaving funny i.e. the image scrolling on it disappears or gets converted into a rainbow.
    Please advise . Any help/comment is welcome. Thanx in advance .

    I'm having the same problem, did you ever find a solution for this?

  • How can I descreen and scale the target image size with a HP 8600 n911 premium?

    I recently purchased an new HP 8600 n911 premium all-in-one, HP's top of the line all in one inkjet printer/scanner.  I cannot find any settings that permit me to descreen an image (such as one in a newspaper) or to adjust the size of the target image.  Is there additional software that will permit me to do this or am I missing something in the software provided by HP?  
    This question was solved.
    View Solution.

    You would need software form a third party to have this option.  The free software that comes with the 8600 doesn't have an option for that. Vuescan is the only software I could find that says it works with your pritner and has a descreen option.  You have to purchase it, but it will give you more advanced options than the software that came with the printer.

  • Most efficient way to handle Image sizes with respect to Mobile Screen Size

    Hi all,
    I and trying to find the best possible way to manage Images with respect to the size of mobile screen.
    If I have an image that is best fit on mobile screen size (176 x 144) then how can I make it best fit for (128 x 128) screen size ?
    rizzz86

    Hey Rizzz86,
    You could also scale down a higher resolution image to fit smaller screens, however you will find that resizing by factors other than 2, 4, 8 is harder to achieve with a decent quality and much slower on lower spec devices.
    You could also display 128x128 image centered on 176 x 144 screen with black borders around it.
    It will look not that bad (i.e. borders of 24 pixels top and bottom and 8 pixels left and right) and will cost you nothing in terms of space or processing.
    In the end having an image in 3 different sizes will not increase the MIDlet size by much, unless you are having tens of such images (for example custom UI elements).
    Best solution is to have a bit of both I think. Personally I use scaling down by factors that are powers of 2 and displaying with the black borders.

  • Reduced DVD image size with HD to SD footage in Encore

    Using CS5, when I encode an SD sequence from Premiere to Encore, all works well.  When I downconvert an HD project through AME it looks fine and shows full screen in Encore, but when I burn a DVD and play it, I get a reduced size image in the center of the screen.
    I'm shooting 1080 24p with a Panasonic HPX170 camcorder.  I create Microsoft AVI files using On Location.
    I use a Matrox MXO2 Mini with Max display unit, so I'm using  these Premiere project settings: 
    Matrox HD
    1990x1080
    [email protected]
    I'm exporting the Premiere timeline using the recommended settings in the Jeff Bellune CS4 tutorial for converting Premiere HD footage to SD for DVD burning
    FORMAT: MPEG2-DVD
    PRESET NTSC 23.976p Widescreen High Quality
    VBR 2 PASS
    Maximum Render Quality
    Min bit rate 2.8 
    Target bit rate 7
    Max bit rate 8
    GOP SETTINGS  M frames 3  N frames12
    Audio 48 kh PCM 16 bits
    Multiplexer NONE
    When I render files and build a project with Encore, the timeline and menu image appears full screen in the Encore monitor.
    When I burn the project to DVD, it displays properly in letterbox on a standard def tv.
    But, when I play the DVD on an HDTV, I get a great looking picture in proper aspect ratio, but it displays at about 3/4 size in the center of the screen with black surrounding it.  I can change the display setting on the HDTV to 'Zoom" and fill the screen with the picture without distortion.
    I have the same issue creating footage at 1080i 60 fps and 1080p 30 fps and building projects with appropriate settings in Premiere and Encore.
    I'm wondering if I'm missing a setting in AME or Encore. I thought I'd followed Jeff Bellune's excellent instructions on HD to SD settings in AME to the letter.
    I'd like to create DVDs that will play full screen on HDTVs and in letterbox on standard def TVs without viewers having to change the settings on their HDTVs.
    FYI, I'm shooting in HD, partially to get really clean keys during the edit, using the Ultra keyer in Premiere. This works great.
    Thanks for any assistance.

    Jeff,
    I went back and checked all the PAR settings and looked at the monitors in 100% mode.  Didn’t solve the problem, but here’s what I found.
    I’m using an avi film clip shot at 1080 24p on the Panasonic HPX170P.
    In CS5 Premiere, I checked the interpret footage setting on the clip.
    It read: Pixel Aspect Ratio: DVCPROHD(1.5)
    I right clicked the timeline to see its properties and saw: PAR 1.5.
    When I checked the monitor at 100% it zoomed in to a close-up of the middle of the image, compared to a full-screen image in “fit.”
    In AME, I used the settings from your Scaling HD to SD using CS4 tutorial and the 1080 24p option.
    When I changed the monitor view to 100% and switched back and forth between SOURCE and OUTPUT views, the SOURCE view was tightly zoomed into the center of the frame, and the OUTPUT view was slightly zoomed in, only losing a bit of the sides of the frame.  Unchecking "Aspect Ratio Correction" squeezed both source and output monitor images horizontally. I rechecked "Aspect Ratio Correction."
    I imported the encoded clip into Encore and checked its PAR.
    The PAR was set to “SQUARE 1.0”
    The 100% view in the monitor was just slightly zoomed in from the “fit” view.
    I tried changing the PAR on the clip in the project window to “Conform to:SD NTSC WIDESCREEN 1.2121.”
    This did not change the 100% monitor view.
    I saved the project and burned a DVD, but saw no change in the menu or clip size. Still small image centered.
    Next I changed the PAR on the clip in the Encore project window to: “Conform to Anamorphic 1.333.”
    This shrank the 100% view to show a letterbox view of the clip, showing the entire clip image.
    I saved the project and burned a DVD.  On the DVD, the menu appeared unchanged, still small and centered. The clip played in full 4:3 aspect ratio, not distorted, with the edges side cropped.
    Any other PAR settings I missed I should access and change?
    Any additional things for me to try?

  • Sei image size with IMAQdx

    Hi, I am using IMAQdx to acquire 640x40 NTSC images from an Euresys Picolo card (DirectShow compatible). If I acquire the image with vision tool from Euresys (Multicam), the image is acquired in the correct format.
    If I acquire the image with grab function from IMAQdx, I see an image of 384x288 pixels in format RGB32.
    It is possible to adjust the image format acquisition from IMAQdx settings?
    Thanks,
    Claudio

    Hi, I am now able to acquire the image with Labview. I have made the correct settings in DirectShow filter (using GraphEdit) and now I acquire NTSC video at 30 fps.
    There is still a problem. In DirectShow filter i have set video resolution to 640x480, but when I acquire image with IMAQdx grab function, the video resolution on image display is 320x240. Do you have some suggestions?
    Thanks,
    Claudio

  • Reducing image size with Preview?

    I notice that Preview's "adjust size" option can considerably reduce the size of some images i got from internet. For instance, with a 366 KB JPEG image, after clicking on adjust size, there would be a line at the bottom of the window that says: 101 KB (was 366 KB). And i know this new smaller sized image has the same quality as the original because when i compare both images at maximum zoom, i see no difference in the size, color or position of the pixels. So, does anyone know how this size reduction method can be applied simultaneously to many images or to an entire folder? Or do you know any software (preferably free) that does something similar without quality loss?
    Thanks in advance

    Then change the subsampling rate or turn it off in the PDF Optimizer.  But realize that in doing so you trade the quality for a larger size.

  • Image size with SL1

    Hello,
    We just got an SL1 and it seems like the images are much wider than they are high, so wide that they look funny. When you take a vertical picture, the image looks very tall and skinny when viewed on the computer. We have it set to the 18mp high quality setting and the pixels match what the camera says, but it doesn't look right on any screen. 
    When I resize regular landscape images for my blog to 2000px wide, the height is only 1333px.
    Typically when I resize them (on my old point and shoot) they would be 2000px x 1500px. 167 pixels is a lot once you get down to uploading lanscape images to places like pinterest.
    This narrow appearance also makes pictures look funny when uploaded anywhere to the web, like facebook or craigslist. 
    Any help/insight would be greatly appreciated. 
    See image below, extra tall and skinny....
    Thanks!
    Ace

    Also note that according to you your old camera was shooting in the 4:3 ratio (2000 X 1500)

  • Correlating image size with DIV size

    Dreamweaver gives me the option called Draw AP DIV.
    (I am guessing this means to define the boundaries of an absolutely positioned Div)
    When inserting an image into a DIV that is created in this manner, is there a way to constrain the size of the image
    to equal the boundaries of the drawn DIV?

  • Wrong image size with a Nikon D70 and another issue

    Hi everyone!
    I'm a photography student and I switched a few weeks ago. I've been using Adobe Lightroom under Windows for months, now I'm trying Aperture.
    I own a Nikon D70, which is a 6 Mpix camera. The resolution of the pictures should be 3008x2000 pixels. With Aperture they are 3024x1998... It's *neither the good ratio neither the native resolution* of the camera.
    What should I do?
    Also, although I set up my camera in MTP mode, it *won't work in tethering mode*. It came back from the Nikon service center with a Nikon D70s firmware, but it should work as well, right?
    Thank you for your help!

    Strange! I had tried with the camera in PTP mode a few days ago, it wasn't working. Trying again now and it works! I must have done something wrong. Thank you anyway!
    Then I tried again the Search tool, I didn't noticed the date range restriction on the first time, now I can see a few threads about that "problem". Although I'm really not satisfied with this "issue", it seems to be this way by design and not a bug.
    Thank you everyone for your help!

  • IE incompatible ? Image size.

    Hi,
    I know very little about HTML, CSS and the like but as a photographer I upload gallery webs all the time for clients etc. I generate these in PS CS2 or iView MediaPro and then upload to my server (shared web hosting).
    With a current project requiring a 'site' type environment I decided to try iWeb. Before visiting this site please note that due to image sizes with iWeb it's a bit on the heavy side and if you're using IE on a PC BEWARE of crashes! Safari may even crash as has done with me.
    http://www.kura-images.com/camping
    Remarks and problems :
    1. As you can see my site does not resemble any iWeb template - using the 'modern' template I basically threw everything away and designed from scratch. It's a great WYSIWYG appli in that sense - no code - just drag and drop, resize, add some effects etc. I published regulary to a folder as a way of double checking but was impressed with the 100% WYSIWYG capability of iWeb
    2. Image size is a MAJOR problem. My concerns are specifically with the gallery pages generated from the photo page temps. Thumbnails at 16ko is too big and the motor that generates the large image files uses a single parameter (800pixels largest dimension) that cannot be changed in any pref settings etc. It also uses a compression factor which is a tad too high. Using Image Ready or the PS gallery web function (driven by Image Ready) I can get as good visual quality for my web-optimised JPEGS for 65% of the file size.
    Note : I tried this file swap as a test
    I changed one image in the folder for the "activités" page (activities_008) - I made a smaller thumbnail in ImageReady and created a 600pixel version of the large file; I replaced the images in the folder with these and checked the site. The thumb appears no problem in a smaller size (btw 6ko vs 16ko - that's a big diff when you apply it to 250 images !). SlideshowJS however has instructions to open the image at main size as determined by the slideshow index file creation generated by iWeb. And that's written as 800pixels. So on opening the 600 pixel image I'd replaced, slideshowJS opened it to 800pixels (not pretty). The only way to rectify that was to go into the source code in the relevant 'activités' js file, find the codeline for the image 008 and change the values manually. And I'd have to do that with 250 line of code ! That rather defeats the prupose of having a nice easy application to produce your galleries.
    3. Upload to my server via Transmit was trouble-free. No problems publishing to a non .mac server.
    4. Problem with the page titles. The names you give to pages determines the URL. Any spaces means you get the %20 thing and if, like me, you're writing in French the accents mean that iWeb has to get around the problem in a different, and not very practical, way. iWeb creates a random character line as a name, and uses that as the URL for pages where accents appear in the title. When the assets and index page are published those long character names appear on the index file and folder.
    I also think that may lead to compatability issues with certain servers.
    5. But here's the BIG PROBLEM !
    I had 4 people with PC's and IE (God bless 'em) check out the site. 2 reported repeated crashes of IE (unexpectedly quit exe. error). No problems with the homepage - just when clicking on some of the photo pages. What is really strange is that neither had problems when accessing the 'La Soirée' page, but both had problems with all the others. Apparently the crash came after IE tried to load the page, succeeded in loading a few thumbnails and then stopped and crashed 5-10secs later.
    6. EVEN WORSE !
    I have gone back to my site several times, emptying Safari cache each time, and have succeded in stalling definitively Safari's attempts to load certain pages. Just stops with partial page upload. I then have to quit Safari and re-open to be able to access any web page (even other sites). Sometimes it's OK, sometimes not.
    This site goes officially live on wednesday morning but for now it's a no-goer. Just too erratic and not IE compatible.
    PLEASE, any suggestions ?
    Many thanks in advance

    Yes, it is best to avoid spaces and accents and special characters if you can. If you must have them in your navigation links, then don't use the iWeb nav bar. Instead give your pages very short simple names with the Inspector, uncheck the box for "include in nav bar," and just create ordinary hyperlinks for page navigation. I don't know if this will help with IE compatibility, but it can't hurt.
