When use_DevIL=true, execution skips the internal parser and goes directly to DevIL. When use_DevIL=false, an attempt is made to parse files with the internal BMP/EBMP parser upon failure – that is, for all image files which are not (E)BMP – DevIL is utilized. When false (the default), give the Developer's Image Library ( DevIL) lower priority, using the internal BMP/ EBMP parser whenever possible when true, always use DevIL, bypassing the internal parser. Any missing files in the sequence are replaced with a blank frame. The first file in the sequence, i.e., corresponding to start, MUST exist in order for clip parameters to be computed. ' end=0' does NOT mean 'no upper bound' as with ImageWriter. The resulting clip has ( end - start + 1) frames. The file corresponding to start is always frame 0 in the clip, the file corresponding to end is frame (end-start). Specifies the starting and ending numbers used for filename generation. If you see the error message ImageReader: error 'could not open file' in DevIL library it may mean that a file was not found or does not exist see Notes below. If file points to a single file (no sprintf pattern), then that file is read once and the image subsequently returned for all requested frames.
For example, the files written by ImageWriter's default parameters can be referenced with "c:\%06d.ebmp". Template for the image file(s), where frame number substitution can be specified using sprintf syntax. ImageSource(string file, int start, int end, float fps, bool use_DevIL, bool info, string pixel_type) string file = "c:\%06d.ebmp" See ImageWriter for more details.ImageReader(string file, int start, int end, float fps, bool use_DevIL, bool info, string pixel_type) * "EBMP" is an Avisynth extension of the standard Microsoft RIFF image format that allows you to save raw YUY2 and YV12 image data. ImageSource("static.png", end = 300) # much, much faster from 2.56 ImageSource("%01d.bmp", end = 50, use_devil = true) # Read files "00.bmp" through "50.bmp" bypassing Avisynth's internal BMP reader # Read files "100.jpeg" through "199.jpeg" into an NTSC clip The resulting video clip is RGB24 if DevIL is used, otherwise is whatever the EBMP was written as (all AviSynth formats supported).Įxamples: # Default parameters: read a 1000-frame native Avisynth EBMP sequence (at 24 fps) Info: when true, the source filename is written to each video frame (added in v2.55). Useful if you need extra performance when reading standard Microsoft BMP files.
When true, execution skips directly to DevIL processing.
Use_devil: when false, the first file is attempted to be parsed as an AviSynth EBMP,* then defaulting to the external DevIL libraries. The first file (i.e., corresponding to 'file' after 'start' is substituted in) MUST exist in order for image parameters to be read in correctly. ('end=0' does NOT mean 'no upper bound' as with ImageWriter). Start, end: if a frame not in this range is requested, a black frame is returned and no file I/O is done. If file points directly to a single filename, then the resulting clip is a static image. For example, the files written by ImageWriter's default parameters can be referenced with the ImageSource default above. It is useful (and faster) when importing one picture.įile: name of the image file(s), where frame #'s can be specified using " ". As of v2.56 ImageSource is equivalent, with some minor functionality changes. ImageReader is present from v2.52, replacing WarpEnterprises' plugin. ImageSource(string file = " c:\%06d.ebmp", int start = 0, int end = 1000, float fps = 24, bool use_DevIL = false, bool info = false)
