# FAQ - Image Collector

I found an animation, but it consists of many files numbered from "animation0001.png" to "animation0020.png" how can I easily import it?

The graphic I got all have some weird background color, how can I easily change that color to be non opaque?

The animations I constructed are quite nice, but they use a lot of memory, since all images are forced to the same size an all have more or less space that isn't needed, can I do something about that, like crop the images?

TT saves all data to some weird xml-format I don't like. I need to save the data in some other format like XXX or YYY, can I use TT to save it another format?

I don't like that the animation of an ImageSequence is allways starting at the same index. How can I change that?
You can check the "Random" checkbox in the "images" section in just above the ImageSequence display. When this checkbox is checked, the animation starts with a random index.

Wording:
Image
Is a file in a graphic format (png, jpg, bmp)

ImageInstance
The ImageInstance is the smallest graphical entity used by TT. It usually is a part of an image. It contains in itself the knowledge of which image it is part of, the coordinates in the corresponding image and the height and width. Many ImageInstances can be put in sequence - and thus building for example an animation.

ImageSequence
Is a single entity in an ImageCollection. It is called "Sequence" since it can itself be a sequence of many ImageInstances, usually resulting in an animation. An ImageSequence can be an animation, if it consists of many ImageInstances or can be a still image, if the sequence consists of only one ImageInstance.

ImageCollection
Is a collection of ImageSequences into one file. The file is saved as a XML file.
