resize the output

I want to change the size of output buffer. So I need to put my code in Frame_Setup according to the sample project 'Resizer'.

What embarrassed me is that only after calculation I can the expected size. But I can't get the image of entry in Frame_Setup.

I don't know how I can solve this problem. I will be grateful if you can give me advice.

BTW, it is not necessary to calculate the size of each time before rendering. What I need exactly becomes input image the first time

I get Frame_Setup function. So I can make sure what is the size of the output video.

Sorry, I gave an ambiguous answer.

You cannot change size during a rendering call, however when you call for a

new made, you'll get a call of Frame_setup firstly, during which you can change

the same size if the frame has been previously made.

  • How to resize the swf output resolution

    Hi all

    is it possible to resize the output swf resolution once the project has been saved?

    I record a request with size 986 x 906 and wouild need t proportionately reduce by 15%.

    How can I do this?

    Thank you

    You did not mention the CP version used. I'll assume that it is CP4. First, you will need to resize the CP file and then republish it. Setting to the scale can lead to loss of quality, but downscaling is especially acceptable if the difference is not so great and you keep the ratio width / height of the same. This is the workflow:

    • Project menu, scale
    • Since you want to reduce by 85% of the original, you can put 85% as a percentage of width and height, but if you keep 'keep proportions' enabled (recommended) with a long
    • the options "If the new size is smaller" will now be available: you can choose to have the upscalees legends or do the editing manually after the scale of the project
    • you won't have to "reframe" (which would have cut the part of the slide if the report is not maintained, which is not your case).

    And then resize...

    Hope this works,

  • Resize the video Square (before Render or after)

    What is your best way to make the video room (example 1000 x 1000) in the output of resize settings I guess? I want to be able to post to a total size of squares. I know it can take a few steps, but did not know if anyone knew a good method or trick.

    Drop your video mockup standard in a new computer the same cadence and the size you require. There is one thing that can clog up the idea however. If you offer a mp4 then there are specifications of frame size that follow or the codec it is auto resize the output. If you want just a black frame your video all about, say back to YouTube, then just create a shape of 1000 X 1000 pixels layer and use as a reverse follow Matt in a model of standard size to your main nested model or place the shape layer on the bottom and enable transparency preserve on all layers above the shape layer.

  • How to clear the output buffer, possibly resize and burn again, before you begin the task of output

    I use PyDAQmx with a USB-6363, but I think the question is generic to DAQmx.

    I have an output buffer that I want to be able to (re) write to without starting the task output.

    More specifically, I have a graphical interface and a few sliders, the user can move.  Whenever the slider changes, a new set of values is loaded into the buffer output through DAQmxWriteAnalogF64.  After you set the value, the user can click on a button and start the task output.

    In some cases the change in cursor does not require a change in buffer size, only a change in the data.  In this case, I get the compalint following DAQmx as they tried writing:

    The generation is not yet started, and not enough space is available in the buffer.

    Set a larger buffer, or start the generation before writing data more than content in the buffer.
    Property: DAQmx_Write_RelativeTo
    Value: DAQmx_Val_CurrWritePos
    Property: DAQmx_Write_Offset
    Corresponding value: 0
    Property: DAQmx_Buf_Output_BufSize
    Corresponding value: 92

    In other cases the change in cursor requires both change in the size of the buffer and data modification.  In this case, I get the following, but only after that do a few times each time increase the size of the writing.

    DAQmx writing failed because a previous writing DAQmx configured automatically the size of output buffer. The size of the buffer is equal the number of samples written by channel, so no additional data can be written before the original task.

    Start the generation of before the second writing DAQmx or set true in all instances of writing DAQmx Auto Start. To gradually write to the buffer before starting the task, call DAQmx Configure an output buffer before the first writing DAQmx.
    Task name: _unnamedTask<0>

    State code:-200547
    function DAQmxWriteAnalogF64

    I tried to configure the output via DAQmxCfgOutputBuffer buffer (in some cases, by setting it to zero or a samples, then save again, in an attempt to clear it) but that doesn't seem to do the trick.

    Of course, I can work around the problem by loading data only when the user clicks the end button, but not what I'm asking here.

    Is it possible to "remake" the writing of output before you begin the task?

    Thank you

    Michael

    Today I have no material practical to validate, but try unreserving task before writing the new buffer:

    DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Unreserve);

    With a simulated device, he made the error go away in case the buffer is the same size.  You will need to validate if the data are in fact correct, but I think it should be (unreserving I would say reset the write pointer so the old buffer are replaced with the new data).

    I always get errors when you try to change the size of buffer if (on my 6351 simulated).  I posted some similar mistakes about the reconfiguration of the tasks here, I guess it is possible that this issue has also been set at 9.8 (I always use 9.7.5 on this computer).  If the behavior is still present in the new driver, and also appears on real hardware (not just simulated), then it seems that this is a bug of DAQmx someone at OR should be considered.

    I wrote a simple LabVIEW VI that captures the error in order to help people to NOT reproduce it:

    The best solution at the moment would be likely to re-create the task if you need to change the size of the buffer (or avoid writing data until you are sure what will be the size of buffer).

  • Resize the internal SSD flash drive

    I recently updated my original internal 750Go disc drive for a new card SanDisk Ultra II 960 GB SSD. Before installing, I cloned the original of this new SSD drive. After installation, I realized there was an amount unallocated free space (209,91 GB) I have involuntary partitioned. I tried to resize the disk several times through various tutorials and searches on google with no luck. Can anyone help?

    Data sheet:

  • Automatically resize the borders of text to the other bars

    I have another script action puzzle im trying to figure out.

    My program has two lines of text, stacked one on the other.

    they adjust to another, depending when the text is entered so that it remains a pretty square.

    the problem is that I can't get the text on the top bars to resize the text on the bottom bar.

    Note, it works the other way around, the background text resizes the text at the top of the page.

    any help would be apperciated.

    Here is my code

    addEventListener (Event.ENTER_FRAME, strehrows, false, 0, true);

    function strehrows(event:Event)

    {

    If (MovieClip (parent.parent) .textSelect == textArray100 ["pair1"], false, 0, true)

    {

    textArray100 ["pair1"] .autoSize = TextFieldAutoSize.LEFT;

    textArray100 ["pair13"] .autoSize = TextFieldAutoSize.NONE;

    textArray100 ['pair13'] .width = textArray100 ["pair1'] .width;

    } else

    If (MovieClip (parent.parent) .textSelect == textArray100 ["pair13"], false, 0, true)

    textArray100 ["pair13"] .autoSize = TextFieldAutoSize.RIGHT;

    textArray100 ["pair1"] .autoSize = TextFieldAutoSize.NONE;

    textArray100 ["pair1'] .width = textArray100 ["pair13"] .width;

    }

    }

    Copy and paste the code that you use.  I can't debug code which is related but not the same as the code you are using.

    In addition, use the trace() function to check the values that you have control and copy and paste the output too.

    for example,.

    addEventListener (Event.ENTER_FRAME, strehrows, false, 0, true);

    function strehrows(event:Event)

    {

    trace (MovieClip (parent.parent).textSelect.name, textArray100 ["pair1'] .name, textArray100 ["pa ir13"] .name);

    If (MovieClip (parent.parent) .textSelect is textArray100 ["pair1"])

    {

    textArray100 ["pair1"] .autoSize = TextFieldAutoSize.LEFT;

    textArray100 ["pair13"] .autoSize = TextFieldAutoSize.NONE;

    textArray100 ['pair13'] .width = textArray100 ["pair1'] .width;

    } else

    If (MovieClip (parent.parent) .textSelect == textArray100 ["pair13"], false, 0, true)

  • Resize the image and maintain proportions

    Hi all

    I'm trying to resize large JPEG images and maintain proportions. I actually managed to write the code, but it's huge, so I wonder if there is an easy way. The next question is about the image resolution. I resize the photos that are 600 and more dpi. Is there a way ColdFusion can resize and reduce the resolution to 72 dpi?

    Thanks for the tips and links

    tomtomtom wrote: And these thumbnails come in a resolution of 600 dpi 
    

    No, they don't.  The files have no IPR - one INPUT (and OUTPUT) devices have IPR.

    Files have the resolution, depth of color, of compression and file format.

    You mix up the quality of OUTPUT with the FILE data.

    You have an image file which is 100px by 100px.  This is the data FILE.  The file has so 10 000 pixels of data (not much for a photo).

    Now if you want the OUTPUT to a monitor at 72 dpi 10 000 these pixels will be appear in a box ~1.38 inches on ~ 1.38.

    If you output to a printer at 300 dpi, it will appear in a box ~0.33 x ~0.33 inches.

    The quality of the image file is the same, but the output determines how small the points are for each pixel, and therefore the size of the overall picture.

    Things that affect the quality of the image file are how many points there are in the file (resolution) how these points are pressed (compression) and file (lossless and lossy) format and how many colors can be used for each point (color depth)

  • Does anyone have a work around for the design on PowerMac G5 2005 flaw that causes noise interference on the outputs? (Audiophile, sound engineer)

    OK, here's my problem - I have a set of audio interface Protools Digi 002 via Firewire 400 on a PowerMac G5 I was lucky enough to be given last year. I finally managed to connect my home recording studio system, he wire of mixer etc, but when I listen to the music coming from the outputs of the Digi 002 there in a great cacophony of audio interference, so much and so well, when I mount the system I can move my pointer between two monitors and it plays a different frequency of buzz. Everytime I open a window, Soft etc it is more electronic noise.

    He took a while to limit, but after reading this excerpt from wikipedia, it seems that it was a fault common to this particular model until Apple released the revised version of the B of the G5 (?);

    ' The first versions of the dual processor G5 have problems of noise . The first is ground loop- based interference,[5] that sometimes causes noise seeps into the outputs audio analogue. This bug has been fixed in Rev. B G5.'

    and

    ' Well that the noise problems do not prevent computers affected work, they asked problems for audio professionals and enthusiasts as well, especially for models to liquid cooling, which had been expressly designed as mechanically quiet for listeners. "

    Well, that's no euphemism - in fact it makes the mac completely useless for my needs, I need the outputs clean digital noise to send for outboard effects/EQ/etc.

    As it was a common fault, I was hoping someone might be able to shed some light on a workaround solution, as I can't imagine recording ground studios just stop until this has been fixed by releasing a new G5?

    The only idea that I came up with so far is to buy a transformer of isolation, but I'm not entirely convinced that will solve the problem?

    Any help on this would be greatly appreciated!

    Thanks in advance

    Have you tried CHUD Tools & turn off NAP mode?

    The first versions of the dual processor G5 have problems of noise . The first is ground loop- based interference,[5] , which causes sometimes analog audio output sound leaks. This bug has been fixed in Rev. B G5.

    The second problem of noise came from his "tweets", which can be triggered by power fluctuations. For example, display or hide the Dock makes a short beep. Many blamed the power supply used in the G5 as the cause, but this theory has never been confirmed. A very effective workaround is to disable microprocessors 'siesta' using Apple CHUD Tools, but this was not recommended by Apple. This noise problem has not set until the generation of dual-core G5s was produced, but it does not affect the model of "Late 2004" (at least there have never been reports). Draw of power fluctuation has been later attributed to the lack of power management features in processors simple heart. [6] Apple eventually posted information bug tweets on its support site. [7]

    Although noise problems did not prevent the computers assigned to work, they were problematic for audio professionals and enthusiasts as well, especially for models with cooling liquid, which had been expressly designed as mechanically quiet for listeners.

    https://en.Wikipedia.org/wiki/Power_Mac_G5

    Just one last note on the use of CHUD tools to disable the 'Nap' on the G5 Dual functionality: restart your machine reactive 'Nap '. You may have already seen this on the Apple forums. Kind of a bummer - although I rarely shut down my machine. In any case, running with 'Nap' off today seems to have resulted in a significant increase in general speed/responsiveness for me (I'm still running the stock 512 MB RAM, with another 1 GB on the way).

  • How to resize the name of add-on Firefox

    The names of some add-on are too big on the toolbar (top) 31 FF. How can I change my name or resize the icons?

    You must use the DOM Inspector to find the ID of each button and set the text of the label max width (this will add an ellipsis) or provide a new text for the label.
    You can do this with the code in the userChrome.css file.

    Add code to the file userChrome.css below default @namespace.

    Here is an example for extension changer TFS:

    @namespace url("https://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */
    
    #themefontsizechanger-toolbarbutton .toolbarbutton-text {

  • can't resize the window of firefox, so I can create the shortcut on the desktop

    You can see the 3 buttons at the top right of the window frame: (_) to minimize, maximize/restore, close (X)? If these buttons are not visible, Firefox may be in mode "full screen". The F11 key toggles between the normal modes and full screen.

    When you use the middle button on the title bar that toggles between maximized and resizable, is visible in the lower right of the Firefox window? If so, you should be able to click and drag up and to the left to resize the Firefox window. If it is off the screen, you should be able to resize the window in two steps: drag the upper left corner of the window down and to the right, and then drag the window to the top of the screen.

    Not sure it's the right answer, but please give it a try.

  • Cannot resize the window as we have after the new update for Firefox

    This morning, Firefox installed an automatic update, and after that, I can't resize the window to a smaller proportion. First of all, let me explain why I do this.

    We have a local Web page to work where we can keep track of some of the statistics, and it is the only area that I need to post. This area I used to reduce the FF window, move until it was in my opinion and freeze it above all other windows (custom AHK script).

    The problem now is that FF resize to the size, it stops at a certain minimum width. Height is no problem, I can resize the height until he is "gone", but the width to a static limit stops.

    Example: Earlier I was able to resize to 500px width, but now it stops at 700px width and will not go lower. Earlier, this could go, like, 10-20px width.

    A bug, or is there a reason for this?
