"Thumbnails" container

Revision as of 23:58, 3 February 2010

Any asset may specify a thumbnail or preview image. The exact usage of this image may vary depending on the asset kind and the build of Trainz, but the following usages are historically common:

• 32x32 - standard icon representation for display in lists.
• 128x64 - ‘kind traincar’ list icon in Surveyor.
• 512x512 - ‘kind traincar’ preview image in Surveyor.
• 240x180 - Download Station thumbnail image - mandatory.

Note: The Art files directory in previous versions of Trainz may now be replaced by the Thumbnails container.

Any number of thumbnail entries may be present, however it is recommended that no more than 3 images are used. The specified width and height must match the actual width and height of the image file in pixels.

Supported image formats include:

• 32-bit uncompressed targa (.tga) - this supports an alpha channel
• 24-bit windows bitmap (.bmp)
• Jpeg (.jpg)

When displaying an image, the closest-sized image required by the function (in terms of pixel dimensions) will generally be used in Trainz.
