Number of rows in the image. 0x0101 ∙ 257
IG_ISIS_TAG_IMAGELENGTH contains the number of rows of pixels (height) in an image.
IG_ISIS_TAG_TYPE_LONG
All source and destination drivers, any many compression drivers.
An integer specifying the number of rows of pixels in the image.
IG_ISIS_TAG_IMAGELENGTH is reset to the full height of the page when several other tags are set; therefore the following dependencies must be observed:
IG_ISIS_TAG_PAGESIZE ∙ IG_ISIS_TAG_XRESOLUTION ∙ IG_ISIS_TAG_YRESOLUTION ∙ IG_ISIS_TAG_XPOSITION ∙ IG_ISIS_TAG_YPOSITION ∙ IG_ISIS_TAG_IMAGEWIDTH ∙ IG_ISIS_TAG_IMAGELENGTH
IG_ISIS_TAG_IMAGELENGTH is required by a number of image viewing applications as well as file writing drivers and any other processes that need to know the number of rows in the image.
