** [bugs:#515] Raster display in low memory situation**
**Status:** open
**Milestone:** OJ_future

This ticket follows ticket #513.
After correction of the bug reported by Roberto Rossi in #513 two problems are
left over.
Images are not loaded permanently in memory, but when they must be shown,
RasterImageLayer evaluates if they fit in memory before trying to display. To
evaluate if the image fits in memory it multiplies the number of pixels by 4
bytes (usual pixel deep for a color image). This evaluation should be more
precise and take into account 1 bit images (b&w) or 64 bits float values.
Also in the case a black and white image is not displayed, the little symbol in
the LayerNamePanel stay colored instead of turning to gray.
