Image Generation

iOS and Android handles images differently. iOS use 1x..3x format and Android uses xxhdpi, hdpi format and so on. To overcome those quirks and seamlessly handle image handling for both OS, Smartface has auto image generation feature embedded in the Smartface IDE.

  • Create automated folder on /images **** directory if it doesn't exist Upload your highest resolution image to /images/automated folder. It will compress and resize the image accordingly.
  • Right click on the image
  • Select Generate auto-resized images
  • Images for different resolutions for both platforms will be generated.

You can use generated images on your project, like images://yourimage.png. For further information about how to use images, refer the document below:

ImageView
Supported Image Types

Only .png images are supported.

Special characters in image name are not supported

You cant use !@#$%^&*()_+-=[]{}|;':",./<>? in the image name.

Image name case sensitivity

Except for AppIcon and LaunchImage, all image names should be in lowercase.

Alternate generate method

You can also use the package sfImageProcessor to accomplish image generation. This package is installed by default on the boilerplate.

info

Multiple image selection is not supported at the moment. For bulk image generation, you can use the script mentioned below or generate them one by one.

Generating Launch Image

  • Name of launch image must be either
    • LaunchImage.png
    • LaunchImage.ios.png
    • LaunchImage.android.png
  • If LaunchImage.png is being used, then launch images for both platforms are generated
  • When the LaunchImage.ios.png or LaunchImage.android.png is being used then launch images for that specific platform are generated
caution
  • LaunchImage.ios.png

  • LaunchImage.android.png

    Is valid for CLI but not for IDE.

Building Smartface Apps
Use square sized launch image

Developers must edit original launch image to make it square sized so that our image processor module can perform resizing & cropping accordingly

info

The name of Launch Image is splash_image on Android.

So you if you want to change your splash image only on Android, you need to find the image with name splash_image from images/Android and replace it with your new image.

For Launch image, to handle different screen sizes better on Android, the developer should create a 9-patch image. The steps are explained below.

    • AppIcon.ios.png
    • AppIcon.android.png
