In all canvas training videos in unity, when creating a canvas, blue dots appear that you can use to scale the object. I don't have any:
enter image description here
How do I add them? Maybe my settings are not the same
The settings are not different. I believe what you are describing is the Rect Tool. You can either select the tool on the top left selection by clicking the icon with 4 vertex points or when you have the editor open, click T and it will automatically swap to this tool. The points on your UI image will appear and you will be able to scale it using them.
I have been searching on how to create a native top bar in Unity with menu item for Android mobile game (the 3 vertical dots and the back arrow) but I couldn't find anything.
So I was wondering if there is a standard Unity way to create a top bar like the native Android or I have to create a custom one?
Here is an image with what I am describing (yellow color is all the bar, and red color the 3 vertical dots)
Thank you.
There is no standard Unity way to create a top bar like the native Android. You have to create a similar UI that looks that the Android menu with the components Unity's UI system This can easily be done if you know the basics of Unity's UI system.
Breaking down the Android menu for Unity:
The three dots can just be represented with the Image or RawImage
component. If you decided to have 3 images(one for each dot) instead
of one image with three dots then use the VerticalLayoutGroup
to group all dots into one.
The search icon could just be a UI Button, Image or RawImage
component.It really doesn't matter. Any of these should work.
You will need a grey background image just the color from the Android
Menu Item. Again, this image will also use the Image or RawImage
component.
You will also need a Text component to show your "Action Buttons" text or any or text you wish to display in the menu.
Finally, group all the components mentioned above into a panel then
use anchor and pivot point to position the panel to the top of the screen.
If you still want to show the Android menu, it is still possible to do:
Create new Android project with Android Studio (Not from Unity. From there, create the
Android menu item.
Export your Unity project and import it into your Android
project in Android Studio.
Modify your Manifest and Activity class code to display your Unity
game as sub-view. You can find more information here. From there
you can even call Unity's function from your Android project with the
UnityPlayer.UnitySendMessage function if needed. Your game will run with any Android UI.
I don't recommend this because it would only work on Android. Also, each time you make changes to your game, you would have to export it again. This is annoying and time consuming. Use the Unity UI system to create this.
Here is my site:
http://smartpeopletalkfast.co.uk/pp/
The 'Shop by Category' menu on the left is made of images and uses PNGs. The PNGs look fine at normal zoom but when I zoom out in FF and also on my Ipad white lines appear where the transparency begins.
I know PNGs can cause lots of headaches cross browser but this seems like a different issue. I havn't tested with other browsers.
Thanks
UPDATE - Does anyone know a link to a site where a PNG with transparency is shown over a background image or color? I want to see if this issue happens to other people in case its impossible to fix.
UPDATE2- I think this only happens on ipad and mac, but not pc.
UPDATE 3 - Here is a screen grab from firefox mac when Im zoomed out:
The problem is that your PNGs actually contain white.
Take a look at your PNG with its alpha channel removed
and compare it to this modified version with the alpha channel removed
Here is the modified version with alpha channel intact: - it looks the same as your file, but the transparent pixels are grey and transparent, not white and transparent. Try this version on your site and it should work.
To help you further, we'll need to know what software you are using to save the images. For example, in GIMP you have to make sure that you select "Save background color" when exporting the PNG, but other software may work differently.
I'm putting an image in a crystal report (using Crystal Reports for Visual Studio 2005). The image is a product logo with a white background, and the report has a white background too. But when I run the report you can see it's not quite white. The off-white color is barely visible, but it is visible and more so when printed.
I've tried a variety of image formats, and tried transparent images too but they don't seem to work (transparent pixels show as black). When I use a different image I notice that the faint non-white color changes - as if it's a function of the colors in the image.
Anyone else encountered this? Any suggestions?
It can be solved directly in the report by checking the option: Retain Original Image Color Depth.
The docs says:
If you want images in your report to keep their original color depth when they are encapsulated, select this option. Otherwise, all images are converted to 8 bits per pixel before being encapsulated.
To check this option go to:
File -> Report Options -> Retain Original Image Color Depth.
Solution to this problem is using images with low color depth. It worked for 8bit PNGs.
If you are generating your own images with Adobe Fireworks you will need to export the image as 8-bit PNG. You can do it using the export tool then in the Options tab change the format to PNG 8 as show in the screenshot below:
If your image doesn't have too much color swatches (< 256) this will not affect the quality, otherwise yes.
It sounds as though the white in the image is actually off-white - have you tried printing the image from another app, such as a browser?
Take a look at this http://kenhamady.com/cru/archives/1480
When I export a png from Photoshop using "Save for Web & Devices" The white color photoshop was picking was actually 1/0/0/0 (CMYK).
In photoshop you can edit these colors before saving, I changed this color to be completely white which seemed to fix my issue.
Programmatically I found reducing the image to 16 bit color resolved the issue
Bitmap result = new Bitmap((int)250, (int)123, System.Drawing.Imaging.PixelFormat.Format16bppRgb555);
I found that even in Crystal Reports for Visual Studio 2012 images need to be of a lower color depth than what is defaulted by many modern editors. High Res images display horribly in the crystal report viewer.
Quick Fix
In GIMP -> Image Menu -> Mode -> Select Indexed As Color Mode
In Index Color Conversion Window
Use Web Optimized pallet.
Ta da. Enjoy.
I'm trying to create the icon for my iPhone app, but don't know how to get the exact radius that the iPhone's icons use. I've searched and searched for a tutorial or a template but can't find one.
I'm sure that I'm just a moron, but how do you get the rounded corners exactly right with your icon from Illustrator or Photoshop?
Edit:
What's the radius for the Retina iPad?
You can make four icons (as of today) for your app and they can all have a different look - not necessarily based on the 512x512 image.
corner radius for the 512x512 icon = 80 (iTunesArtwork)
corner radius for the 1024x1024 icon = 180 (iTunesArtwork Retina)
corner radius for the 57x57 icon = 9 (iPhone/iPod Touch)
corner radius for the 114x114 icon = 18 (iPhone/iPod Touch Retina)
corner radius for the 72x72 icon = 11 (iPad)
corner radius for the 144x144 icon = 23 (iPad Retina)
If you do create a set of custom icons, you can set the UIPrerenderedIcon option to true in your info.plist file and it will not add the gloss effect but it will place a black background under it and still round the image corners with these corner radii so if the corner radius on any of the icons is greater then it will show black around the edges/corners.
Edit: See comment from #devin-g-rhode and you can see that any future icon sizes should have a 1:6.4 ratio of corner radius to icon size. There is also a very good answer from https://stackoverflow.com/a/29550364/396005 which has the location of image mask files used in the SDK for rounding icon corners
To add a retina-compatible file, use the same file name and add '#2x'. So if I had a file for my 72x72 icon named icon.png, I would also add a 114x114 PNG file named icon#2x.png to the project/target and Xcode would automatically use that as the icon on a retina display. You can see this in action on the Summary page of the application target if you've done it right. The same works for your launch images. Use launch.png at 320x480 and launch#2x.png at 640x960.
After trying some of the answers in this post, I consulted with Louie Mantia (former Apple, Square, and Iconfactory designer) and all the answers so far on this post are wrong (or at least incomplete). Apple starts with the 57px icon and a radius of 10 then scales up or down from there. Thus you can calculate the radius for any icon size using 10/57 x new size (for example 10/57 x 114 gives 20, which is the proper radius for a 114px icon). Here is a list of the most commonly used icons, proper naming conventions, pixel dimensions, and corner radii.
Icon1024.png - 1024px - 179.649
Icon512.png - 512px - 89.825
Icon.png - 57px - 10
Icon#2x.png - 114px - 20
Icon-72.png - 72px - 12.632
Icon-72#2x.png - 144px - 25.263
Icon-Small.png - 29px - 5.088
Icon-Small#2x.png - 58px - 10.175
Also, as mentioned in other answers, you don't actually want to crop any of the images you use in the binary or submit to Apple. Those should all be square and not have any transparency. Apple will automatically mask each icon in the appropriate context.
Knowing the above is important, however, for icon usage within app UI where you have to apply the mask in code, or pre-rendered in photoshop. It's also helpful when creating artwork for websites and other promotional material.

Neven Mrgan on additional icon sizes and other design considerations: ios app icon sizes
Bjango's Marc Edwards on the different options for creating roundrects in Photoshop and why it matters: roundrect
Apple's official docs on icon size and design considerations: Icons and Images
Update:
I did some tests in Photoshop CS6 and it seems as though 3 digits after the decimal point is enough precision to end up with the exact same vector (at least as displayed by Photoshop at 3200% zoom). The Round Rect Tool sometimes rounds the input to the nearest whole number, but you can see a significant difference between 90 and 89.825. And several times the Round Rectangle Tool didn't round up and actually showed multiple digits after the decimal point. Not sure what's going on there, but it's definitely using and storing the more precise number that was entered.
Anyhow, I've updated the list above to include just 3 digits after the decimal point (before there were 13!). In most situations it would probably be hard to tell the difference between a transparent 512px icon masked at a 90px radius and one masked at 89.825, but the antialiasing of the rounded corner would definitely end up slightly different and would likely be visible in certain circumstances especially if a second, more precise mask is applied by Apple, in code, or otherwise.
I see a lot of "px" discussion but no one is talking percentages which is the fixed number you want to calculate by.
22.37% is the key percentage here. Multiply any of the image sizes mentioned above in by 0.2237 and you will get the correct pixel radius for that size.
Before iOS 8, Apple used less rounding, using 15.625%.
EDIT: Thanks #Chris Prince for commenting with the iOS 8/9/10 radius percentage: 22.37%
Important: iOS 7 icon equation
With the upcoming release of iOS 7 you will notice that the "standard" icon radius has been increased. So try to do what Apple and I suggested with this answer.
It appears that for a 120px icon the formula that best represents its shape on iOS 7 is the following superellipse:
|x/120|^5 + |y/120|^5 = 1
Obviously you can change the 120 number with the desired icon size to get the corresponding function.
Original
You should provide an image that has 90° corners (it’s important to
avoid cropping the corners of your icon—iOS does that for you when it
applies the corner-rounding mask)
(Apple Documentation)
The best approach is not rounding the corners of your icons at all. If you set your icon as a square icon, iOS will automatically overlay the icon with a predefined mask that will set the appropriate rounded corners.
If you manually set rounded corners for your icons, they will probably look broken in this or that device, because the rounding mask happens to slightly change from an iOS version to another. Sometimes your icons will be slightly larger, sometimes (sigh) slightly smaller. Using a square icon will free you from this burden, and you will be sure to have an always up-to-date and good looking icon for your app.
This approach is valid for each icon size (iPhone/iPod/iPad/retina), and also for the iTunes artwork. I followed this approach a couple of times, and if you want I can post you a link to an app that uses native square icons.
Edit
To better understand this answer, please refer to the official Apple documentation about iOS icons. In this page it is clearly stated that a square icon will automatically get these things when displayed on an iOS device:
Rounded corners
Drop shadow
Reflective shine (unless you prevent the shine effect)
So, you can achieve whatever effect you want just drawing a plain square icon and filling content in it. The final corner radius will be something similar to what the other answers here are saying, but this will never be guaranteed, since those numbers are not part of the official Apple documentation on iOS. They ask you to draw square icons, so ... why not?
People arguing about the corner radius being slightly increased but actually that's not the case.
From this blog:
A ‘secret’ of Apple’s physical products is that they avoid tangency (where a radius meets a line at a single point) and craft their surfaces with what’s called curvature continuity.
You don't need to apply corner radius to icons for iOS. Just provide square icons. But if you still want to know how, the actual shape is called Squircle and below is the formula:
The answer from dbarnard has the formula to calculate the correct radius, but since you were looking for the templates, all the masks and overlays can be found in this directory:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/System/Library/PrivateFrameworks/MobileIcons.framework
(path is for recent versions of XCode. For older version it will probably be inside /Developer/).
As others have noted, you should NOT mask them yourself, but you can use these to check how your icons will look once masked.
(credits for this finding goes to Neven Mrgan IIRC)
The corner radius of the 57 x 57 pixel icon is 9 pixels.
As others have said, you don't want to round your corners. You want to ship flat (no layers or alpha) square graphics. Apple changed the mask they use for rounding your corners in iOS7 and then again in iOS8. You can find these masks inside your Xcode application bundle. The path changes with every new SDK version they release. So, I'll show you how you can always find it.
find /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs -name 'MobileIcons.framework'
At this very moment, the path found by that command is /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/MobileIcons.framework but don't trust that. Use the command to find it yourself.
That path points to a directory with these files (again, at the time of this post)

As you can see, there are a lot of different masks, but they are named pretty clearly. Here is the AppIconMask#3x~iphone.png image:
You can use that to test your icon to see if it will look okay after it is masked. But, don't round your corners. If you do, when Apple changes those masks again, you will have artifacts.
All the previous answers to this question are now out of date. Since at least May 2015, Apple requires you to provide square icons with no rounding:
Keep icon corners square. The system applies a mask that rounds icon corners automatically.
https://developer.apple.com/ios/human-interface-guidelines/graphics/app-icon/
If not considering stroke, the exact radius is actually 10px for 57x57 icon.
I get this info from iconreference.
Update (as of Jan. 2018) for App Icon requirements:
https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/app-icon/
Keep icon corners square. The system applies a mask that rounds icon corners automatically.
Keep the background simple and avoid transparency. Make sure your icon is opaque, and don’t clutter the background. Give it a simple background so it doesn’t overpower other app icons nearby. You don’t need to fill the entire icon with content.
The iphone rounds corners for you, all you need is a square 57x57 png icon and u should be good
When designing my app icons with Photoshop, I have found that no integer corner radius fits the device's mask exactly.
What I do now is create an empty project with Xcode, set a completely white PNG file as the icon, and turn off the preset bevel & gloss. Then, I run the app and take a screenshot of the home screen. Now, you can easily create a mask from that image, which you can use in Photoshop. This will get you perfectly rounded corners.
There are two totally conflicting answers with large number of votes one is 160px#1024 the other is 180px#1024. So witch one?
I ran some experiments and I think that it is 180px#1024 so drbarnard is correct.
I downloaded iTunes U icon from the App Store it's 175x175px I upscaled it in photoshop to 1024px and put two shapes on it, one with 160px radius and one with 180px.
As you can see below the shape (thin gray line) with 160px (the 1st one) is a bit off whereas the one with 180px looks just fine.
This is what I do now in PhotoShop:
I create a canvas sized 1026x1026px with a 180px mask for main
design Smart Object.
I duplicate the main Smart Object 5 times and resize them to 1024px, 144px, 114px, 72px and 57px.
I put a "New layered Based Slice" on each Smart Objects and I rename slices according to their size (e.g. icon-72px).
When I save the artwork I select "All User Slices" and BANG! I have
all icons necessary for my app.
I tried 228px radius for 1024x1024 and it worked :)
You don't need to apply corner radius to your app icon, you can just apply square icons. The device is automatically applying corner radius.
WWDC 2022 brought good news!
Now, Xcode 14 automatically generates all the required app icon sizes based on a single input icon 1024x1024 pix (Single Size). However, if you need an old-school approach, choose All Sizes from dropdown menu.
So, all you have to know now is the radius of input icon which is 180 px.
