FileOpenRaw

Path

[File|Open Raw|Predefined] or [File|Open Raw|Interactive]

Usage

The predefined menu item will read a raw unsupported file directly, using the current settings available. These settings are either from a previously interactive read or from a currently loaded raw predef input file. See also "File|Raw Predef Load".

With the interactive item you can attempt to read unsupported formats without compression. It allows you to supply information about header and image layout, needed to extract the images from the file. Note that this will override any loaded predefined properties. After the file selection dialog you will be asked to enter some header information:

Header Information

Total number of images

Entry for the number of images to read.

General header offset (bytes)

Entry for the size in bytes of a global header structure that needs to be skipped once at the beginning.

Image header offset (bytes)

Entry for the size in bytes of a header structure to be skipped before reaching the actual image.

Repeated image header (true/false)

Toggle button: the above image header size is repeated before each image in the file.

Swap pixel bytes (true/false)

Toggle button: wether the bytes of pixel values need to be swapped between little or big endian. (pixel endian <> host endian)

Identical images (true/false)

Toggle button: the following dialog dimensions and pixel types are identical for all images.

Continue

Button to continue...

Cancel

Button to cancel

After giving the header structure, you will be prompted to define an image structure.

Images Information

Offset in Bytes

Give an absolute offset in bytes to the image data. This ofcourse overrules all previously defined offsets.

Columns

Entry for WIDTH / COLUMS (X) dimension.

Rows

Entry for HEIGHT / ROWS (Y) dimension.

Pixeltype

Radiobutton to select pixeltype.

Next

Button to select next image.
  or

Finish

After all input, begin the reading sequence ...

Cancel

Cancel the whole procedure.

When the images are not identical, you will see this kind of dialog with a Next button until the structure of the last image was given. At the end you will see the Finish button which will initiate the reading procedure. In case all images are identical, the image structure must be given only once.

After a successfull attempt, you can always save your settings for later usage. Details can be read on the following Raw Predef Load & Save page.
