PODOFO Impose est un logiciel en ligne de commande permettant de réarranger les pages d'un document PDF. Il est particulièrement utile pour créer des "impositions" -- des signatures et ainsi générer des livret à imprimer.

Son usage est le suivant:

for i in *.txt; do
podofoimpose pdf_list.txt 2in1poster.pdf superimpose.plan lua
done

• pdf_list.txt est un fichier texte contenant une liste de documents PDF à traiter
• 2in1poster.pdf est le nom du fichier de sortie
• superimpose.plan est le nom du fichier contant les instructions lua pour réarranger les pages

Superposer plusieurs documents

-- superimpose.plan
-- source: Pierre Marchand/Prince Charmand

-- Required
PageWidth = SourceWidth
PageHeight = SourceHeight

-- Records
i = 1
while i <= PageCount
do
        -- PushRecord(sourcepage, targetpage, rotation, x, y)
        PushRecord(i , 1 , 0, 0, 0)
        i = i + 1
end

Arranger plusieurs pages sur un format plus grand

-- arrange.plan
-- A lua plan for podofo-impose that arranges pdf pages onto a bigger page
-- Similar to Imagemagick montage command

-- The size of our target document. Here: an A3 (in pt)
PageWidth = 842
PageHeight = 1191

-- Computes the number of columns and rows
cols = math.floor(PageWidth / SourceWidth)
rows = math.floor(PageHeight / SourceHeight)
itemsPerPage = cols * rows


-- Records
currentSourcePage = 1
while currentSourcePage <= PageCount
do
    -- the current column
    currentCol = (currentSourcePage - 1) % cols
    -- the current x position
    x = SourceWidth * currentCol

    -- the current row
    currentRow = math.floor((currentSourcePage - 1) / cols) % rows
    -- the current y position
    y = SourceHeight * currentRow

    -- the current page
    currentTargetPage = math.ceil(currentSourcePage / itemsPerPage)

    -- PushRecord(sourcepage, targetpage, rotation, x, y)
    PushRecord(currentSourcePage, currentTargetPage, 0, x, y)

    currentSourcePage = currentSourcePage + 1
end
