New page

An [[Image file]], or "source image", stores a single 2D image, typically in RGB format with an optional Alpha (opacity) channel. This is not the same as a [[texture file]] used for 3D rendering, but an image file may be referenced as a source image by a texture.txt file.

A number of standard interchange formats are support by Trainz for image files. In some cases, limitations may be set on what features may be used in the image file- for example, specific types of compression or format options.

=Supported File Formats=

== PNG ==
PNG is a lossless compressed image format with alpha channel support. This is the best choice where compatibility with older versions of Trainz is not required.

== Targa (TGA) ==
Targa is a lossless image format with optional compression and optional alpha channel. This is a sensible choice for texture source images where compatibility with older versions of Trainz is desired.

== JPEG (JPG) ==
JPEG is a lossy image compression format with no alpha channel support. This is suitable for larger non-texture images, such as thumbnails, screenshots, etc. This format should generally be avoided for textures since it will typically lead to the image being compressed in a lossy format (JPG), decompressed, and finally recompressed again into another lossy format.

Since each open-edit-save cycle may further degrade the quality of a JPEG file, it is not recommended to store work-in-progress images in this format.

= Use in Texture Files =
Image files may be used as the source image for [[texture file]]s to be used in 3D rendering. Additional restrictions and options are present for images used as a texture; the [[texture file]] page should be consulted for details.

A single image file should not be simultaneously used as both a source image for a texture file and also for other purposes. When archiving content for distribution, [[N3V Games]] may perform a one-way conversion of all texture files into a device-specific format, erasing any source images used by the texture. In this scenario, the source image is no longer available for other uses.

= Color Space =
Images should use the SRGB color space except where documentation for the specific use-case indicates otherwise.
