ImageReader
(string "file", int "start",
int "end", float "fps", bool
"use_DevIL", bool "info", string "pixel_type")
ImageSource

ImageSourceAnim

ImageReader
is present in v2.52, it replaces WarpEnterprises'
plugin, with some minor functionality changes. As of v2.55
ImageSource
is equivalent, with some minor functionality changes.
ImageSource
is faster than ImageReader
when importing one picture.
file: template for the image file(s), where frame number
substitution can be specified using
sprintf syntax.
For example, the files written by ImageWriter
's
default parameters can be referenced with "c:\%06d.ebmp". As of v2.56 if the
template points to a single file then that file is read once and subsequently
returned for all requested frames.
start = 0, end = 1000: Specifies the starting and ending
numbers used for filename generation. The file corresponding to start
is always frame 0 in the clip, the file corresponding to end is
frame (end-start). The resulting clip has (end-start+1) frames. 'end=0' does
NOT mean 'no upper bound' as with ImageWriter
.
The first file in the sequence, i.e., corresponding to 'start', MUST exist in order
for clip parameters to be computed. Any missing files in the sequence are replaced
with a blank frame.
fps = 24: frames per second of returned clip. An integer value prior to v2.55.
use_DevIL = false: When false, an attempt is made to parse (E)BMP files
with the internal parser, upon failure (prior to v2.56) DevIL processing is invoked. When true,
execution skips directly to DevIL processing. You should only need to use this if
you have BMP files you don't want read by ImageReader
's
internal parser.
NOTE : DevIL version 1.6.6 as shipped with Avisynth does not correctly support DIB/BMP type files that use a pallette, these include 8 bit RGB, Monochrome, RLE8 and RLE4. Because the failure is usually catastrophic, from revision 2.56, internal BMP processing does not automatically fail over to DevIL processing. Forcing DevIL processing for these file types is currently not recommended.
info = false: when true, the source filename and DevIL version is written to each video frame (added in v2.55).
pixel_type = "rgb24": Allow the output pixel format to be specified, both rgb24 and rgb32 are supported. The alpha channel is loaded only for rgb32 and only if DevIL supports it for the loaded image format. (added in v2.56).
The resulting video clip colorspace is RGB if DevIL is used, otherwise it is whatever colorspace an EBMP sequence was written from (all AviSynth formats are supported).
Supported formats are:
ImageSourceAnim
(added in v2.60; requires 1.7.8
DevIL.dll) lets you import
animations (gif, ppm, tiff or psd). If there is a delay between the first and
second image in the animation, the framerate is set accordingly. If this delay
is zero, the framerate is set to 24 fps by default (and can be adjusted by
setting the fps parameter). Note that pixel_type is set to RGB32
by default. If the images in the animation have unequal dimensions, then the
dimension of the first image is taken and the remaining images are padded with
black pixels below and or to the right.
1.7.8 DevIL.dll can be downloaded here. Just put the DevIL.dll in your system folder (it will overwrite the 1.6.6 DevIL.dll which comes with AviSynth). Be sure to use the non-unicode version, because the other one will result in crashes when loading pictures.
DevIL.dll 1.7.8 requires the 2005 VC runtime libraries to be correctly installed: Visual C++ 2005 SP1 Redistributable Package (x86).
# Default parameters: read a 1000-frame native AviSynth EBMP sequence (at 24 fps) ImageSource()
# Read files "100.jpeg" through "199.jpeg" into an NTSC clip ImageSource("%d.jpeg", 100, 199, 29.97) # Note: floating-point fps available in v2.56
# Read files "00.bmp" through "50.bmp" bypassing AviSynth's internal BMP reader ImageSource("%02d.bmp", end = 50, use_DevIL = true)
# Read a single image, repeat 300 times ImageSource("static.png", end = 300, use_DevIL=true) # Much, much faster in v2.56
# Read a greyscale (8-bit) jpg: ImageSource("GoldPetals-8bit.jpg", use_DevIL=true)
# Read a greyscale (8-bit) BMP (using AviSynth's internal BMP reader): ImageSource("GoldPetals-8bit.bmp")
# Read a YV24 BMP (created with ImageWriter): ImageSource("GoldPetals-24bit.ebmp")
# Use a still-frame image with audio: audio = DirectShowSource("Gina La Piana - Start Over.flv") video = ImageSource("Gina La Piana.jpg", fps=25, start=1, end=ceil(25*AudioLengthF(audio)/AudioRate(audio))) return AudioDub(video, audio)
# Read an animation: ImageSourceAnim("F:\TestPics\8bit_animated.gif")
