Âfbfade gradually displays an image on a frame buffer, one randomly chosen pixel at a time.
(âhigh resolutionâ)Assumes 1024 by 1024 pixels for default input image size instead of 512 by 512. Explicitly specified sizes override the default, and if actual input image size is smaller than requested, the actual size will be used. If output frame buffer size is not specified, the revised input size will be requested for output. If actual output frame buffer size is greater than requested, only the lower-left portion of the frame buffer will be used. Actual sizes depend on details of specific frame buffers.
Inputs the image to be displayed from the specified frame buffer or pix(5) file, instead of using pure background (which fades out the image already on the output frame buffer).
Specifies input image width and height.
Specifies input image width.
Specifies input image height.
Specifies output frame buffer width and height.
Specifies output frame buffer width.
Specifies output frame buffer height.
Outputs to the specified frame buffer instead of the one specified by the ÂFB_FILE environment variable (or the default, if ÂFB_FILE is not set). If this is the last option specified, the Â-F is optional.
The following shell script can be used to produce a slick âslide showâ:
fbclear for âi âin â*.pix do fbfade â-f $i sleep â15 done fbfade
