Image To Display

To choose the image that shall be displayed in a Picture Graphic use this property.

Any supported image file can be selected from the file system. Supported formats are:

•Bitmap Windows Bitmap (*.bmp)

•JPEG Joint Photographic Experts Group (*.jpg, *.jpeg, *.jpe)

•PNG Portable Network Graphics (*.png)

•GIF Graphics Interchange Forrmat (*.gif)

•SVG Scalable Vector Graphics (*.svg)

•TIFF Tagged Image File Format (*.tif, *.tiff) (only single layer images. With multilayer images only the first layer will be used)

In general all images are scaled to size of the Picture Graphic object and converted to PNG format when saving the project.

Two exceptions exist:

•GIF images will neither be scaled nor converted. They will be saved 1:1 to the device so that GIF animations can be replayed.

•SVG images are also not scaled or converted when saving the project. They will be scaled directly on the target.

In general, please use images in the exact resolution that they will be displayed in on the device. Higher resolutions don't improve the quality, they lead to a higher memory demand and the scaling can produce a lower image quality.

Fit To Image Size

Enable this property to change the size of the Picture Graphic object to the size of the image selected with Image To Display property.

Default value: Enabled

Possible values:

•Disabled: Image will be scaled to size of Picture Graphic

•Enabled: Picture Graphic will be scaled to image size

The GIF properties are not displayed in the properties table of the Picture Graphic object.

They can only be accessed with the JavaScript functions getProperty() and setProperty().

WARNING: Using large animated gif images can slow down the device at runtime significantly. Testing gif images on the target device is strongly recommended!

The GIF properties allow to control the playback of GIF animations on the device. The following properties are available:

GIF State

Use the GIF State property to control the playback of the video. It can be started, paused or stopped. The values for the GIF State are integers, see below.

Default value: 0 (Stop)

Possible values:

•0 (Stop)

•1 (Play)

•2 (Pause)

Example for how to use this property in a JavaScript:

var objectID = 42;

//Start the GIF animation

setProperty(objectID, "GIF State", 1);

//Pause the GIF animation:

setProperty(objectID, "GIF State", 2);

//Stop the GIF animation

setProperty(objectID, "GIF State", 0);

Note that the default value is stopped. This means that each animation on each page has to be started manually in a script. If this is not done, only the first frame of the animation will be displayed.

GIF Speed

The playback speed of a GIF animation can be set with this property. If this property is not changed, the animation will run with the speed configured in the GIF itself.

Note that large GIF animations might run a little slow when playing them the first time (the images will be cached the first time it is run).

The value for this property is the percent speed of the original speed defined in the GIF (100% means unchanged speed).

Default value: 100%

Possible values: 1 ... 34359738367% (it is not recommended to set such a high speed)

Example for setting 50% (half) speed for an animation:

var objectID = 42;

setProperty(objectID, "GIF Speed", 50);

GIF Loops

This property is a boolean property that controls if the animation will loop to the start of the animation when it's end is reached.

Default value: true

Possible values:

•true - Begin at start of animation when end of animation is reached

•false - Stop animation when end of animation is reached

Integrated in GIF files is a number of loop repetitions information, so even if looping is set to true, after a certain amount of repititions the animation will stop. Sadly this information is hardly editable in GIF-editors.

Example for setting the GIF Loops property:

var objectID = 42;

//Stop animation when end is reached:

setProperty(objectID, "GIF Loops", false);

//Enable looping:

setProperty(objectID, "GIF Loops", true);

GIF Frame Number

It is possible to jump to a certain frame number of the GIF animation. Like this an animation can be played frame by frame or jump to a special frame.

Default value: 0

Possible values: 0 (first frame) ... number of frames of the GIF animation

If a number greater than the actual number of frames of the animation is set, it will be ignored.

Example:

var objectID = 42;

//Jump to frame 5

setProperty(objectID, "GIF Frame Number", 5);

Note: Frame counting starts at 0.
