Transparent border appears when I use Image Size to shrink an image (bug)

In CS2 (9.0.2) and CS3 (10.0.1), whenever I shrink an image using Image Size, my layers get a slightly transparent edge. As a game developer, I make tiling textures a lot, and this generally ruins their tiling-ness.
Try this:
- create a 32x32 image, make it white
- add a layer, fill it with black
- shrink it to 16x16 or 20x20, using any of the Bicubic resampling methods
- notice that the edge pixels of the black layer are slightly transparent. This is most noticeable in the corners of the image.
Is there a better place for me to report this bug? I haven't found one.

Haha, you mean it's a bug in the spec rather than a bug in the implementation? (Unless there is actually a reason someone would want it to work that way.)
Yeah Bilinear and Nearest Neighbor both avoid the problem, but of course the image doesn't look as good.
I work around it by duplicating all my layers before shrinking. The problem is obvious (in-game) with only one layer, but still subtle enough that it's usually invisible after duplicating. Annoying, but it works.

  • When I use a tool on an enlarged image the image freezes and I can't get it to move unless I change tools. I tried resetting tools and uninstalling and reloading CC. What should I do?

    When I use a tool on an enlarged image the image freezes and I can't get it to move unless I change tools. I tried resetting tools and uninstalling and reloading CC. What should I do?  Once any tool is used I can't change its size or move the image.

    Howdy,
    Sorry for the lack of info. It is Adobe Photoshop CC, I have been using
    CS5 and am trying the trial version of CC to see if it worth changing
    to. Any tool works once but freezes the tool sizing and image movement.
    I am also using the Beta version of Mac Yosemite. But the CS5 version is
    working fine.

    To move an iPhoto Library to a new machine:
    Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
    But however you do choose to link the two machines...
    Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
    Then hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
    and select the Library that you moved.  That's it.
    This moves photos, events, albums, books, keywords, slideshows and everything else.
    Your first option didn't work because you imported one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.
    Your second option didn't work because you simply referenced her library on the old machine.

  • Certain web forms have formatting options like those found in Microsoft Word. They don't appear when I use Firefox, but do with IE of course. Is there a way to get it to display?

    Certain web forms have formatting options like those found in Microsoft Word. They don't appear when I use Firefox, but do with IE of course. Is there a way to get it to display?

    That formatting feature for text areas is known as Rich Text editing. Easy to enable on the web page with one line of code to tap into the Midas package that Mozilla uses, but the users can't enable it themselves from within Firefox.

  • AVG Secure Search appears when I use Google Search from my Home page only.

    My home page is the Firefox default page with the Google searchbar. I like getting occasional messages from Firefox when I log in so I don't want to change my homepage. However, when I use the searchbar ''on my homepage only'', I get the unsatisfactory AVG Secure Search results.
    UPDATE: I now realize all the troubleshooting information I included in my original question appears under the "More System Details" link next to the question, not in the body of the question. I have copied it here to make it easier to see what I have already done to try to solve the problem, as well as describe the one clue I have that may be relevant:
    I have tried all the fixes on various threads, but my about:config is now pristine (no avg or isearch mentions; keyword.url is default). Closest solution is that at https://support.mozilla.org/en-US/questions/866327 , which requires changing my home page.
    Oddly, AVG Secure Search is ''not'' a problem when I use the Google toolbar or search from the Google website, only when I use the search bar that appears on my home (start) page. This is true even when I return to my home page--if I search from the Google search bar in the middle of the page, I get sent to AVG Safe Search. (isearch.avg.com).
    I read in one thread a suggestion to delete my chromeappsstore.sqlite file in my Profile folder. As promised, Firefox created a new one when I restarted it; however, the search bar in the middle of my home home page did not work at all. Tried this three times before restoring my original.
    I do not have an application that will open a sqlite file, but I tried doing so in Excel and found a cell containing the following:
    emoh.:moz-safe-aboutsearch-engine{"name":"AVG Secure Search","searchUrl":"http://isearch.avg.com/search?cid={7A3C25A0-E345-4507-AA31-D98F596A81A9}&mid=c48135235ba247d18ac1d14b344db451-addd29eab2809954d5abdf0b991a5b911a297819&ds=is015&lang=en&v=10.0.0.7&pr=sa&d=&sap=dsp&q=_searchTerms_"}
    I have no clue what that means, but it is the only thing I can find related to Firefox that still mentions AVG and isearch.avg.com.
    At this point my best guess (but it is a guess) is that the chromeappsstore.sqlite file is a key to the complete solution, but I do not have enough knowledge to go beyond and address it. I appreciate any help you anyone can offer.

    Here is the way to get rid of the problem once and for all:

  • I have been organizing my bookmarks into folders. There are a bunch of bookmarks that appear on the Bookmarks Menu that do not appear when I used the Organize Bookmarks option. Therefore I can't organize them. How do I get at them and move them to folders

    I used Organize Bookmarks to put some bookmarks in folders. When I had done all the bookmarks that appeared outside of folders in the Organize Bookmarks window, I closed it and looked at my bookmarks menu. Under my folders were some other bookmarks that I hadn't seen in Organize Bookmarks and when I used it again, they still weren't visible. Therefore, I couldn't move them into folders.

    Update - I discovered that the entire list of bookmarks can be accessed in the Organize Bookmarks window by clicking on the icon for Bookmarks Menu.
    This seem like odd interface behaviour to me.
    All the other software I use follows the pattern that an icon with a triangle to the left, which you click on to expand the menu tree downwards, shows the entire contents of the category when you click on the triangle. In other words, you don't get a different response by clicking on the icon from what you get by clicking on the triangle.
    It also seems odd to me that when an unsorted bookmarks folder is automatically provided that unsorted bookmarks would not be placed there by default.
    Anyway, by getting the list of bookmarks displayed this way I was able to simply right-click on items in the list and delete them, as I thought I should be able to do. Problem solved. Organize Bookmarks interface found to be somewhat unintuitive.

  • "Border" appears when I click on a button

    Hello,
    I'm creating a rollover button graphic to open a friend's
    webpage. His logo is a circle; I am creating a rollover effect that
    depresses the circle when you rollover and click.
    Here's the strange problem, and this has come up before: when
    you click on the button in Firefox, a "border" appears where I
    created a slice. This doesn't happen in Safari. It's a bit
    disconcerting, as it takes away from the effect.
    I'm sure there's a simple fix. Any ideas? Thank you in
    advance.

    That's actually an accessibility feature built into the
    browsers. It
    appears in IE as well as Firefox. You can override it, but
    that's not
    recommended.

  • Why does the message '500 internal server error' appear when I use any search engine?

    I am able to type a web address and use the internet successfully but when using ANY search engine I get the '500 internal server error' message. This appears if I type in a word to search '''bold text'''and the result is the error message. I have recently uninstalled rapport and hitman pro. Please help.

    Did you check your security software (firewall)?
    Which security software (firewall) do you have?
    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

    There are options depending on exactly what you want to do and why you want to do it.
    In general: these are options in the File -> Export dialogue. The Jpeg Quality setting refers to file size, the Size option refers to dimensions.

  • Image size for 4:3 format appears somewhat zoomed in when viewed on my TV

    I am using Final Cut Express HD to create movies and have just started using iDVD '08 to create dvds, and have run across something bothersome in iDVD:
    When I view the iDVD movies on my TV that were created in a 4:3 format (640x480 resolution) in Final Cut, the image appears somewhat zoomed in versus what I see on my computer. This is causing problems with the composition of the image as it appears on the TV screen that do not appear when viewing the movie on my computer. Here's how:
    When viewd on the TV:
    1) the TV image's edge is zoomed in about 5-10% on all four sides relative the image edge as viewed on the computer screen
    2) when the scale of an image is reduced over time from 100% to something less (e.g. 50%) based on motion/scale keypoints in the clip's motion tab), the image detail starts zooming out but with the image size still filling the TV screen, then somewhat afterwards, the image size on the TV grows smaller as zooming out progresses.
    Overall this disparity between computer screen image size and TV screen image size is causing two miscues with how the movie shows:
    a) the composition of the picture is altered because it defaults to being somewhat zoomed in relative to the image I see when creating the movie on my computer, with whatever image I have on the true edge (per the computer screen composition) not appearing on the TV screen and
    b) the timing of changes in image SIZE relative to audio or other video cues is thrown off in a way that seems difficult to predict when designing the motion effects in Final Cut.
    Any advice on how to fix this?

    Hello phdtobe,
    what you're experiencing is overscan - a normal phenomenon with CRT monitors - and has nothing to do with neither FCE nor iDVD.
    Try using the "Action Safe" setting in FCE's Viewer to see the "crop area".
    hope this helps

  • My keyboard will not appear when i am using Notes App

    My on screen keyboard does not appear when I use Notes app. The + sign (to add a new note) does not function to create a new note
    Does anyone have any answers
    Thanks

    Try closing the Notes app completely and see if it works when you re-open it : from the home screen (i.e. not with Notes 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Notes app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
    If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
