Member Function Documentation

load()

IJB & IJB::load

(

const File &

filename

)

Load the given .ijb file.

Exceptions

Lox::Exception	if the file does not exist
Lox::Exception	if the file is impossibly small (no content?)
Lox::Exception	if the file cannot be opened (permission problem?)
Lox::Exception	if the file is not a valid .ijb bitmap
Lox::Exception	if the file has an invalid size (width, height, or length)

Here is the caller graph for this function:

extract_image()

Image IJB::extract_image

(

)

const

Extract the image data from contents, and re-build a new user-viewable image.

Instead of calling this directly, see the image stored as img.

References IJB::RecIJB::data, IJB::RecIJB::height, rec, and IJB::RecIJB::width.

const Image &

new_image

)

Exceptions

Here is the caller graph for this function:

create_browseable_image()

const IJB & IJB::create_browseable_image

(

const bool

force = false

)

const

Create a PNG file in the same directory as the IJB, and name it so it is obvious which image corresponds with each .ijb.

Parameters

force

Images are only written if they don't already on disk, unless true is passed in which forces the image to be re-written.

Member Data Documentation

contents

VBytes IJB::contents

The entire contents of the file is loaded into this vector.

Referenced by load(), set_new_image(), summary(), and ~IJB().

rec

const RecIJB* IJB::rec

Pointer to the bitmap record. Should point to nullptr or the first byte of contents.

Referenced by create_browseable_image(), SessionComponent::edit_description_field(), extract_image(), load(), SessionComponent::paintCell(), set_new_image(), summary(), and ~IJB().

file

File IJB::file

.ijb file.

Referenced by create_browseable_image(), load(), set_new_image(), summary(), and ~IJB().

img

Image IJB::img

The image file extracted, rotated, and flipped from the .ijb file.

This is automatically done by extract_image() when the .ibj file is first loaded in load().

Referenced by SessionComponent::buttonClicked(), create_browseable_image(), load(), SessionComponent::paintCell(), set_new_image(), and ~IJB().
