Image Modes
 

Introduction

An image-mode is a global parameter that tells Chasys Draw IES how to interpret layers. For example, the “frame animation” image-mode tells Chasys Draw IES to treat layers as video frames, while the “imagelist--multi-res” tells it to interpret them as copies of the same image at different resolutions (e.g. what you find in an icon file).

The concept of an image-mode is unique to Chasys Draw IES and changing image-modes can drastically alter how the application behaves. It is therefore important to understand what the various image-modes are designed for and how they behave.

Some layer attributes, options and blend-modes may be unavailable when using certain image-modes. This is by design; such attributes may not make sense in the selected image-mode (e.g. blend-modes make no sense in image-lists because the items do not interact with each other). The rendering of the workspace may also change.

 

The “Composite” Image Mode

The first sub-mode of this mode is the default image-mode in Chasys Draw IES. The layers are interpreted as composite layers of a single image, and are combined to create a single final visual output as dictated by the blending-modes and other layer attributes.

Put differently, the layers are treated as transparent sheets of transparent plastic with images drawn on them, that can be stacked on top of each other, so that you can see the lower sheets through the transparent parts of the upper sheets as shown below:

There are two sub-modes under this group:

Normal

Everything works as explained above.

 

Clipped

The output is clipped in the workspace as well to give an editing experience that is similar to other image editors for those who are not used to free-style layering.

 

 

The “Image-List” Image Mode

In the image list image-mode, many images, possibly with different content and resolution, are treated as separate entities. The destination device then has a choice of images to choose from, depending on the intended display resolution and/or other factors. This mode is primarily used for creating icons and brushes, but may also be used for albums and the like.

There are two sub-modes under this group:

Everything works as explained above.

 

Multi-res

Chasys Draw IES assumes that the images only differ in resolution; the content is assumed to be the same. When viewed in Chasys Draw IES Viewer, only the highest-resolution image is shown.

 


The “Frame Animation” Image Mode

The frame animation image-mode is used for short videos, known as animations, by way of defining the frames individually. In this mode, only one layer is displayed at a time, one after the other, after a duration of time dictated by the frame delay layer attribute. It is analogous to the way an artist can draw a slightly different figure on each page of a pad of paper so that when you flip between sheets rapidly, the drawing appears to move. Shown below are two layers in frame animation mode:

NB: I think someone owns the copyright to this cartoon character. If so, copyright, them.

You are not limited to two layers, however. You can have a hundred frames in your animation if you so wish. Here is a more elaborate (but not detailed or physics-correct) example:

 

There are two sub-modes under this group:

Sub-mode Meaning
Normal

In editing mode (i.e. when using Chasys Draw IES Artist), all the frames are shown as separate entities that can be manipulated independently.

 

Onion-Skin

In editing mode (i.e. when using Chasys Draw IES Artist), all the frames are shown as one entity using the onion-skinning method of animation. This technique involves making frames translucent and projecting them on top of each other to mimic the method used in traditional cartoon animation, where the individual frames of a movie were initially drawn on thin onionskin paper over a light source. Doing so allowed the animators to draw new frames using the old ones as references, thereby making it easy to achieve smooth transition between the frames in the final video.

The image below shows the onion-skinning of the animation of Homer Simpson jumping:

The “Object Animation” Image Mode

The object animation image-mode is used for short videos, known as animations, by way of defining the behaviour of objects. In this mode, each layer that has some movement or change associated with it is assigned special attributes that define that behaviour, which Chasys Draw IES then uses to animate the layer in the preview window. The changes are defined against time in using the Animation Timeline window shown below:

The following attributes can be animated:

Attribute Meaning
x_pos, y_pos

The X and Y positions of the layer. These attributes can be animated to move the layer over time.

alpha

The transparency of the layer. This attribute can be animated to change the visibility of the layer over time.

Very elaborate animations can be created using such definitions; the animation below is an example done using this method:

There's only one sub-mode under this group:

Sub-mode Meaning
Normal

Normal timeline-based editing mode.

 

 

You can convert an Object Animation into a Frame Animation using the “Render Object Animation” option on the “Animation” menu in Chasys Draw IES Artist. This may be useful if you want to export the animation as a GIF or AVI file. Please note that the reverse cannot be done; you cannot convert a Frame Animation into an Object Animation. If the animation is too long or too big to be converted to a Frame Animation within the workspace, you can render it directly to a video file using the “Animation Renderer” device plug-in by going to the “File” menu then selecting “Send to Device”.
