Sprite Bear is an app for smart phones and tablets to create sprite sheets on the go and collaborate with developers and designers instantly to get updated through email, dropbox etc.
Sprite Bear precisely transforms the large number of art assets into the sprite sheets by overcomes smart phones and tablets memory and computing limitations over desktop. Sprite Bear have many options available in the settings to adjust things based on your project requirements .
Canvas:
All sprites added will be combined into the sprite sheet with updated settings will be rendered real-time in the canvas screen.
Assets Library:
All sprites added into the product will be available in the assets library where quickly sprites can be inserted or deleted from the sprite sheet. swipe the asset from the library brings options to add or delete sprite into the sprite sheet.
Auto Size:
Automatically adjust the size every time when new assets added. but also set the fixed size by setting the fixed width and height in the settings panel. assets which not fit within the fixed size will be flushed and will be listed in the “outside bounds” section in the assets panel.
Rotation:
Rotate the atlas frames, in order to save more space in the atlas, and perform more efficient frame packing.
Gestures:
Pinch gesture to set the zoom factor on the texture
Pan gesture to move the texture
Trim wth fuzz:
Trim the transparent and noisy area on the edges to reduce the file size and space by setting the trim fuzz factor on the settings panel.
POT (Power of 2):
The "Power of Two" rule is a fundamental necessity due to the way game engines work. Theres actually a long history associated with game and content development that has to do with the way computers manage and process data in limited chunks, rather than all at once, for purposes of efficiency. These chunks are important in regards to the "Power of Two" rule because they establish a set of hard coded, physical restrictions on media that must be conformed to, else a given games rendering engine will waste resources fixing the assets so they do. In essence "Power of Two" is a data optimisation, a necessity so images are as efficient and lite as possible whilst providing an appropriate visual experience.
Scale Variants:
Simply create all the sprites for the highest resolution then scale down your assets for the devices with the lower resolutions.
Create multiple scale variants in settings panel than apply scale value and suffix for a specific type of a device, scaling down from the Retina version of a device to non Retina display is simply scaling down by 0.5.
Texture Formats:
This specifies the graphics file format desired for the sprite sheet.

Png-8 (palette)
Jpeg

Tiff
Tga
Pbm (monochrome)
Data Formats:
This provides you the ability to select the format for your data files to match your game framework.

Cocos2d V2.0

Starling / AS3
Pixel Formats:
This specifies the pixel format to use in the texture file. These settings affect things like how many bytes are used per pixel of the graphic.
Sprite Bear applies the colour quantization according to the settings. colour reduction reduces the memory usage but still produce sufficient colours to build the target colour values.
