Select the Bitmap

I know this is a vague question but could someone try to explain the steps involved in the creation of a selection on a bitmap? (similar to the in Photoshop selection tool). I'm not looking for any code I was wondering what is involved. Thank you.

OK, it's much more complex.

For the moment let's ignore touch screens.

So, basically, you are going to have to display the Bitmap, and then, when the focus is on this bitmap, display a kind of cursor/pointer.  You need to replace the painting and this match draw in front of your Bitmap image.

This slider will have to meet the navigationMovement.  The user must be able to "click" to select an area, or maybe to do the standard "drag" to select a rectangular area.  Once you have this area (you know where it is because you are viewing the cursor), you use getARGB on the Bitmap image, get rough ints, convert this back to a Bitmap, scaling it.

Make sense?

  • Select the color of bitmap images or grayscale in InDesign CC 2015.4

    Hi all

    Since InDesign CS1, I'm used to be able to import levels of grayscale or bitmap graphics, and then select the color in InDesign.

    I just had to choose the "Direct Selection" tool, click on the graphic and select another color.

    Since InDesign version CC 2015.4 it no longer works.

    No workaround is it available?

    Thank you

    Hi Robin,

    This is a bug with InDesign CC 2015.4.
    To set the end of August.

    So far, you could always leave the preview overlay mode on.
    So the bug is not visible.

  • How to change the bitmap image in blackberry

    Hello

    1. work on the version of BB storm (9500/9530 Simulator) is v4.7.0.75
    2 opportunity BB JDE 4.7
    3. the request is:

    I display a bitmap image by using the drawBitmap method. now I want to select a portion of the bitmap, and then I need to cut & paste the part somewhere in the screen (MSPaint we have option 'Select').

    is there any method that will make the similar operation (or) any idea to accomplish this in blackberry.

    Thank you

    Take a look at this thread and refers to the J2ME code:

    http://supportforums.BlackBerry.com/Rim/Board/message?board.ID=java_dev&message.ID=24929

    The 'trick' is getARGB() and setARGB().  As long as you check out relevant Bitmap Moose ARGB values, you should be able to create a new Bitmap.  That said, I never did.  Let us know how you go.

  • How can I clean the Bitmap Images imported

    Hi, I am using Flash 5. I have imported a .png image sequence and they look pretty rough and bitmap so I wanted to clean them.

    1. what I have to select each frame after import and adjust the settings of the bitmap for each image or I can doo this somewhere so it affects al images?

    2. I can't find the settings to clean up the bitmaps. I thought they would be in the Panel "Properties"?

    3. is it possible to set the pixelation or clean a .swf imported or is it better to clean the sequence before you save it as a .swf?

    Ideally, you should have images cleaned / correctly size / optimised before import you them into Flash.  Once they are in Flash, one thing that you can do that can help how the image appears, especially if manipulate you its size in Flash, is to set the image to allow smoothing.  This can be set using code or can be applied manually to the image in the library do a right-click, selecting Properties and by checking the option to allow smoothing.

  • Create a copy of the bitmap of a TextFlow object without the circumflex [cursor]

    Hey all

    I am currently working on creating a copy of the bitmap of a TextFlow object and I try to hide the caret. What would be the best way forward, using the Manager of focus 'unfocus' the TextFlow, or is it more direct approach available? I know there's a cursormanager in Flex, but it is a single AS3 project.

    Bravo for your thoughts, once again

    EMD

    Your SelectionManager has three properties of format of selection - targeted, blurred and inactive. Those that can be defined for SelectionFormat objects, which have parameters for the cursor. You can set pointColor in the background, or pointAlpha to zero.

    If you know the format of targeted selection is one, you might have code like this:

    var fFormat:SelectionFormat = mySelManager.focusedSelectionFormat;
    mySelManager.focusedSelectionFormat = new SelectionFormat(fFormat.rangeColor, fFormat.rangeAlpha, fFormat.rangeBlendMode, fFormat.pointColor, 0);
    // get the bitmap now that the cursor alpha is set to zero
    // then set it back
    mySelManager.focusedSelectionFormat = fFormat;
    
  • Change the bitmap image, remove background in Flash CS4?

    HI people, I tried to slide in Photoshop, a layer with a transparent background, and image but it becomes white in Flash, so I imported the psd image. However, the black background interfere with the placement of the image. In OLD flash, there was formerly a magic wand and the ability to select areas of the bitmap and delete, but it seems that the feature is now missing or hidden in the new flash.  I transformed the image bitmap and I don't want to follow, because it's a picture. So, without tracking, how you change the image as I am doing?

    Thank you

    Jeff

    The magic wand is in the same place in CS4 (select Lasso, and then it is in the area of the toolbar options).

  • which updates of the bitmap blocks

    Hi friends,

    He comes to issue credits and hope without required versions.

    We know that information will be retained in the freelist freeblock / bitmap blocks. lets say taken DBWR freeblock information (either from freelist / bitmap block) and inserted a few lines in a free block. This block is now "USED BLOCK". I want to know exactly who will be updated (any background process?) the status of the block of FREE USED in freelist / bitmap block.

    Thanks in advance.

    Pavan - a disciple to Oracle wrote:
    Hi Aman, thanks for the update. but in one of the positions, sybrand mentioned that freelist will there be in PGA.
    Please refer to the free in the buffer cache blocks

    + 1) this may be different for the free lists and bitmaps. Free lists are / were stored in pga. Bitmaps I'm not sure. I need to check it out. They are stored in the database, so it is likely that they are in the buffer cache. +

    can you please explain a little more...

    Hmm interesting!

    Well, as I don't know about Oracle at all so I can't say that its right or wrong. Sybrand is a very high and competent guy and his very rare he gets something wrong so the best would be to wait for him to come and explain it.

    That said, the segment has a property called free list and this also shows in the properties of the Segment and the dictionary, _tables.  For example, look here,

    SQL> select * from v$version;
    
    BANNER
    --------------------------------------------------------------------------------Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production
    PL/SQL Release 11.1.0.6.0 - Production
    CORE    11.1.0.6.0      Production
    TNS for Linux: Version 11.1.0.6.0 - Production
    NLSRTL Version 11.1.0.6.0 - Production
    SQL>  create tablespace test datafile '/u01/app/oracle/test.dbf'
      2  size 3m
      3  segment space management manual;
    
    Tablespace created.
    
    SQL> create table test (a number) storage(freelists 2) tablespace test;
    
    Table created.
    
    SQL> select table_name, freelists from user_tables where table_name='TEST';
    
    TABLE_NAME                      FREELISTS
    ------------------------------ ----------
    TEST                                    2
    

    Now, if the Freelist is created in the PGA, it would mean that his will be the specific property of the session which will be there after the closure of the session which seems wrong isn't? So in my humble OPINION, its there in the segment itself, not in the pga and so are the bitmap blocks. If you want to see them being created, you can see them.

  • Unable to select the file in the dialog box in the Sierra

    I'm unable to select an image file in the "save for Web" in the finder window "save under" in Photoshop CC running on the Sierra.

    There are times where I need to save a new image using a similar name by selecting the existing file, which matches the name in the dialog box "save under".

    The use of Photoshop CC in Sierra I am unable to do so due to the inability to select the existing files in the Save-as the finder window.

    I thought at first that was Adobe, but later, I noticed that I can not save for web browsers and other programs. I installed the beta updates on Sierra, but also which did not set. I hope be fixed so I can move on to Sierra. It was not such a problem in previous versions.

    Unfortunately, your discovery is correct. I just met for the first time. I was shocked, but apparently it will work in list view. View miniature not a reason any.

  • cannot select the disk to install the update of the Sierra (Macbook Pro 13 inch, late 2011)

    I downloaded the update of the Sierra and proceeded with the installation. However, I noticed that even if I could move the pointer autour, I couldn't make selections on tapping the trackpad. I managed to get past the first steps by using the 'tab' key (keyboard) to make selections and 'space' to make the confirmations. However, arriving at step 'select the disk where you want to install Mac OS', the 'Tab' and 'Space' technical has stopped working. Now I'm stuck here. Can someone tell me please how to go beyond this?

    Looks like it's a problem of trackpad? Or in any case a trackpad issue connected with installation of Sierra? I would take the MBP for a Genius Bar...

  • Impossible to select the uniqueness

    I'm unable to select unique characters in documents Pages by using my trackpad. I click on w/one finger, then check the box on the other hand, as I always have done and can do in this online editor. The character will show in blue light, but as soon as I raise my left finger of the trackpad to type, the highlighting disappears. For awhile, I thought that it was not possible to replace a selection in a document typing, as typing would be always inserted beside the original characters. This feature works sometimes, but does not work most of the time.

    Pages using 5.6.2 & El Capitan.

    I'm not on a Mac at the moment, but you can use a combination of arrow keys + shift + option keys to select the different characters, words, lines, paragraphs and documents together.

    Experiment.

    Hi nothing Jack,.

    I understand that you are not able to choose which audio track plays for your Quicktime movies. I know it's important to understand the language in your videos, so I'm happy to provide some clarification for this.

    When you watch a video in Quicktime format, use the menu bar to select view > languages. From here, you can choose which you do not want to use the audio track.

  • UI of Firefox is slow by typing or selecting the text (after update 33.0)

    After the 33.0 update, I noticed that typing a backspace in any area on a Web page or even in the Firefox address bar is slow to echo, on a lag of 1 second. Also, by selecting the text typed (to remove a TI, etc.) by a click-and - drag quick selects the entire, but when I click in the dialog box to deselect, the part which has not been posted as selected initially, is selected for a moment before the string whole hilite selection disappears.

    What makes the browser very cumbersome to use.

    This seems to be new to 33.0. I tried to reset Firefox, but it does not solve the problem. No problem in IE 11.0, so I do not think that the malware. I have also to keep all s/w and run avast/zonealarm for safety. I've never had an infection of malicious software on this machine. Win7 Home Premium 64-bit, 8 GB of RAM. The use of resources is low, so not out of process control.

    I have request the latest Microsoft "Patch Tuesday" updates 15/10, the same day that I updated to Firefox. This can complicate the diagnosis. But even once, IE was not affected, then, how the different Firefox UI for basic keyboard/screen I/O?

    If there is an easy way to "downgrade" to the 32.0.3 prior revision, I could try to confirm. Help, please!
