### 5.4. Export File

The “Export file” is opened when you try to save a file in a format which does not support several layers or transparency.

The file format does not support animation

Portable Network Graphics (PNG)

  Figuur 14.74. Export PNG file dialog

  The PNG format, a lossless format, supports transparency but doesn't support animation. So, you only can Flatten image, i.e merge layers into a single one, according to the mode you have selected for the image.

JPEG File Interchange Format (JFIF, JPEG)

  Figuur 14.75. Export JPEG file dialog

  The JPEG format, a compression format with loss, doesn't support animation nor transparency. The file will be flattened and transparency will be replaced with the background color of Toolbox.

The file format supports animation

Multiple-Image Network Graphics (MNG)

  Figuur 14.76. Export MNG File Dialog

  The MNG format is an animation format and supports 256 transparency levels (which, at last, are recognized by Internet Explorer 7). The dialog offers two options. Select Save as animation, since Flatten Image does not make sense here. Note that MNG images are not recognized by GIMP.

Graphics Interchange Format (GIF)

  Figuur 14.77. Export GIF File Dialog

  The GIF format, less sophisticated than the MNG format, supports 256 colors and 2 transparency levels only.

  The dialog offers you either Flatten Image or Save as animation. See the glossary ( GIF™ stands for Graphics Interchange Format. It is a file format with good, lossless compression for images with low color depth (up to 256 different colors per image). Since GIF was developed, a new format called Portable Network Graphics (PNG) has been developed, which is better than GIF in all respects, with the exception of animations and some rarely-used features. ) for more details about the GIF format.

  If you have not transformed your image into a 256 colors indexed image before, this dialog will ask you choose between Convert to grayscale and Convert to indexed using default settings. Be careful: an indexed image undergoes a severe loss of colors and the added palette can give it a size bigger and a quality less than if it was saved as JPEG.
