Scaling of images without breaking the report l / h

IM in a situation where I need to scale images in terms for the container into which he kept...

Is there a formula to find the value of the scale that should be applied to the image (I put the maximum size of the container)? Any ideas would be very nice...

Thank you.

Welcome to the forum.

I'm not sure that understand the issue here.

Say you have an image of height and width b.  You want to scale to fit in a container of width x and height y.  Then the scale factor you use, to ensure that the image fills the container as much as possible, without upsetting the aspect ratio is simply

min (x/a, y/b)

For example, suppose that your image is 100 x 150 and you want to fit it into an area 30 x 40

the formula gives:

min (30/100, 40/150)

This, at what scale will fill all the way up, but not the width.

Hope it makes sense.

  • Replace images without affecting the interpretation?

    Hello group,

    I often move or rename files while working on a project, so AE reported as absent.  When I use "Replace Footage" to find images, AE changes the interpretation of the images, which affects the composite.  Does anyone know if there is a way to replace images WITHOUT affecting the interpretation of the images?

    Fine thanks

    Brian

    Apparently, there is no official way to replace without affecting the interpretation.

    But it might be a fairly easy way: don't forget interpretation > replace > Interpertation apply.

    It with the text of the interpretation rules file would make all automatic.

    If the TM drive storage is full TM automatically deletes the version the oldest files for the new incremental backups can be made. Thus, in this case you cannot restore the versions that TM deleted because it takes more storage.

  • Display of the image without covering the circle behind

    Dear all,

    I have a great difficulty to display an image without covering the 'circle' behind. I have a circle in the center of the screen. The circle is the circle of draw by draw .vi. After a while, a table is displayed in the Center. But the circle behind is still required to demonstrate. I used playback .jpg, etc... to display the image. When the image is on, however, it covers the 'ring '. I can't do it in re-trace the circle on top of the image due to timing because of the sensitivity of the search. Could you please provide suggestions? Thank you very much!

    Yonghe

    How about two indicators of photo?  One on the top that contains the circle but otherwise has a transparent background.

    The indicator of the photo that you draw your other image is backward in your z-order of the controls on the front panel.

  • Move items outside of loops without breaking the threads

    Hi all

    is it possible to spend a few elements and their son outside a loop without breaking the connections? He became a real pain when you have more items to move and reconnect everything one by one.

    Thank you very much!

    Today, there is no option to do this directly. Which would probably require less work is to detach the buckle, move objects and then draw the loop again, but it would depend on the amount of work is required to configure the loop (shift registers, etc.). You will probably be able to write script code to do this (or to move the code outside the loop and rewiring it), but I expect that the work required to write and test the code will be larger than the work required to do this. You could do a search for the Quick Drop 'remove and rewiring' plugin to see how it works, as it does part of the work.

    A few years ago, NEITHER showed a demo of an experimental tactile editor who had this behavior integrated, if at least they are aware of him and maybe you will see in BT at a given time.

  • How to delete an image without deleting the layer?

    I consider myself an intermediate photoshop user. Since the introduction of the CS6, I can't do something simple - remove an image without deleting the layer. I don't want the deleted layer because it has a clipping mask. The tech support agent told me to use the Eraser tool. It is not effective. Is there a way to do this? I don't understand why it is now so complicated. I'm so frustrated.

    Has CTRL or cmd to select all, and then press the delete key. Just make sure that the layer is selected first.

  • Scaling a 2D image without using the zoom factor

    I currently have a large 2D image and several smaller 2D iamges that overlap the magnified image.  The big picture is created with the draw in labview, while smal iamges are created with a png image.  Magnification on the enlarged image is 7, while 2D of png images must be scale par.21 to fit in the big picture properally.  As 2D images are stacked, while the rear image updates sometimes "flickers" through the small images.  To resolve this problem, I can combine images, but it does not work because different zoom factors.  Is there a way to reduce an image without using a zoom factor?  Is it possible that I have to scale the bitmap programmatically?

    Thank you for your time

    Hello

    I developed a BI letter when I display the logo dynamically. I have the image file stored in a BLOB of table field and then download the image using a procedure. I used the URL in my SQL report and changed the text of replacement on the image, but I still not able to view the image.

    I created a test in oracel.apex application

    PKTEST workspace

    user pktest

    pass 123test

    I checked the old post and is therefore but it does not work.

    Solve the problem.

    There are several cause to the problem.

    to start the process

    PROCEDURE SAMPACC. "" DISPLAY_COMP_LOGO "(number p_refno)

    is

    l_logo blob.

    number of l_length;

    Start

    -You can select one of your own table where you store the image

    Select

    colo_logo, DBMS_LOB. GetLength (colo_logo)

    in l_logo, l_length

    create a public SYNONYM DISPLAY_COMP_LOGO for . DISPLAY_COMP_LOGO;

    Grant execute on DISPLAY_COMP_LOGO to anonymous, public, APEX_PUBLIC_USER

    then connect to aid the user in the system database, and then set it to the current schema

    for example, Alter session set current_schema APEX_040200

    for apex 4.2

    change the following function to include the name of the procedure you

    APEX_040200.wwv_flow_epg_include_mod_local

    After modification, the function should look like this. If you have a false return after start this comment.

    and call the procedure with parameter example

    Select apex_application.get_g_base_href |' #OWNER #. DISPLAY_COMP_LOGO? P_COLO_REFNO =' | COLO_REFNO as company_location COMPLOGO

    create a template and insert an image where you want to display the logo.

    Select the image and right click and select Format on the property dialog box and the image passes to the last tab and enter the following text in the alt text field

    URL: {//COMP_LOGO}

    Save the template and upload in your application, then go to the report query and select the model.

    You can run this in your application. If you test in the report query report then you must change the #OWNER # of your schema name.

    I used my own company site table in the explanation. I created an application in apex.oracle, but it does not work because I can't change the function as

  • How to change the resolution of the image without shrinking the image in Photoshop?

    Hello world. In Photoshop, if you change the resolution to 300 to 72 image it automatically changes the size of the image (narrowing it) but if export you for the web, he transforms it in 72 DPI without changing the size of the image! How can we just change the image resolution in photoshop while keeping the image of the same size (pixels high and wide) on screen? It is a problem because if the resolution is higher than the text is smaller! (when I put text) if I really need all my images 72 dpi without their shrinkage. Does anyone know how can this be achieved? Thanks a lot for your help.

    Uncheck resampling in the dialog resize. Frankly, if you post on the web, all that really matter is the pixel dimensions. The 72 dpi is really meaningless. A lot of post of places they need to 72 dpi, just to try to do that people don't give big files, but you submit something within the propler pixel size, it can be any dpi.

  • Export only a single layer as an image without hiding the other layers?

    I know I can just do a single visible layer, and then save PNG, for example . But my question is: I have to do all the other layers in order to save invisibile only my one layer as image? Or is there a way to record only a single layer (or a few at a time) without hiding the rest of them?

    If you have Photoshop CC, you can use the new Adobe generator to export single layers without worrying about the other layer visibility.

    If you do not have CC or you do not use the generator, you must either turn off layers or fooled into a new document. Photoshop itself cannot save a single layer in a document of several layer.

    so I am very confused if the error is in the report or the table/data type definition itself.

    Or {noformat}) {noformat}

    The problem is in the settings of the P4_PICTURE element in the form on page 4. The Type of storage has been upgraded with WWV_FLOW_FILES of the Table, so the uploaded images were going to the repository of integrated files, not the BLOB on your CATEGORY table column. So the fundamental problem is that there are no images in your table to be included in the report.

    I changed the element P4_PICTURE Type of storage to a BLOB column specified in the attribute of the Source element, has added the additional column information and the IMAGESource and changed column PHOTO report 3 Format page mask download image, and the picture I have uploaded via the updated form the appears.

    That's right, use the handles, hold down Cmd + Shift at the same time to constrain the proportions.

    To zoom in, try CS5 spring tools.  When you work with photos etc handles, hold down Z and draw around where you want to zoom in or click on as needed.  Then, once you have zoomed in to where you want to go to release Z and you return to your selection tool.
