iprint utility
Prints the RGBA values for an image as text.
Synopsis
iprint [-H] [-C] [-F] [-x xoff] [-y yoff] [-w width] [-h height] ImageFileDisplays list of pixel values in RGBA order
-H in hexadecimal
-F in floating point 0. → 1.
-C in a compact form
Description
iprint displays the R, G, B and Alpha values for an image as a long list of ascii text. By default, all pixel values are displayed - one pixel per line, with the X and Y coordinates followed by the R, G, B and Alpha values. The range is 0 to 255.
Options
|
-x and -y |
Specify x and y offsets to be applied to the picture, and -w and -h options specify width and height of a subframe, limiting what is displayed. |
|
-H |
Indicates that the pixel values should be displayed in hexadecimal rather than the default decimal values. |
|
-F |
Indicates that the pixel values should be displayed in floating point format in the range 0 to 1 rather than the default decimal values. |
|
-C |
Indicates that the pixel values should be displayed in a compact form. Instead of each pixel on a separate line, each pixel is separated by two spaces, and each scanline starting a new line. This form is usable by other Houdini tools which utilise arrays. |
|
-A |
Indicates that the pixel values should be displayed in the form of a Houdini ascii channel file with no headers and one row per scanline. Any combination of r,g,b and a may be given to select which of the red, green, blue or alpha pixel values should be output. |
