Images from the library directory, that are shared across multiple # documents. # # 2. Images that are document specific. # # For library images this file ensures that they are copied in to the # documents directory so that they can be reference properly. # # For library images *and* document specific images, this file ensures # that the images are converted from their repository format to the # correct output format. # # # Using document specific images # ------------------------------ # # The images that each document provides *from the repository* are listed in # the IMAGES variable. # # We then need to build a list of images that must be generated from these. # This is to handle the case where a document might include some images as # bitmaps and some as vector images in the repository, but where, depending # on the output format, you want all the images in one format or another. # # This list of generated images can then be cleaned in the clean target # later # # This is the same for each format. To use IMAGES_GEN_PNG as an example, # the substitution means "First match, using M, all the components of # ${IMAGES} that match the '*.eps' regexp. Then, search/replace the .eps # in the matching filenames with .png. Finally, stick the results in the # ${IMAGES_GEN_PNG} variable." ${IMAGES_GEN_PNG} then contains the names # of all the .eps images listed, but with a .png extension. This is the # list of files we need to generate if we need PNG format images. # # The PDF generation, when it's looking for file 'foo', will first try # foo.pdf, and it will try foo.png. There's no point converting PNG files # to PDF, as they'll be used directly. However, we can convert the EPS files # to PDF, and hopefully get better quality. # IMAGES_EN?= LOCAL_IMAGES_EN?= # # The name of the directory that contains all the library images for this # language and encoding # IMAGES_EN_DIR?= ${.CURDIR}/../../../share/images .for _curimage in ${IMAGES_EN} LOCAL_IMAGES_EN += ${IMAGES_EN_DIR}/${DOC}s/${.CURDIR:T}/${_curimage} .endfor _IMAGES_PNG= ${IMAGES:M*.png} _IMAGES_PNG+= ${LOCAL_IMAGES_EN:M*.png} _IMAGES_EPS= ${IMAGES:M*.eps} _IMAGES_EPS+= ${LOCAL_IMAGES_EN:M*.eps} _IMAGES_SCR= ${IMAGES:M*.scr} _IMAGES_SCR+= ${LOCAL_IMAGES_EN:M*.scr} _IMAGES_TXT= ${IMAGES:M*.txt} _IMAGES_TXT+= ${LOCAL_IMAGES_EN:M*.txt} _IMAGES_PIC= ${IMAGES:M*.pic} _IMAGES_PIC+= ${LOCAL_IMAGES_EN:M*.pic} IMAGES_GEN_PNG= ${_IMAGES_EPS:S/.eps$/.png/} IMAGES_GEN_EPS= ${_IMAGES_PNG:S/.png$/.eps/} IMAGES_GEN_PDF= ${_IMAGES_EPS:S/.eps$/.pdf/} IMAGES_SCR_PNG= ${_IMAGES_SCR:S/.scr$/.png/} IMAGES_SCR_EPS= ${_IMAGES_SCR:S/.scr$/.eps/} IMAGES_SCR_PDF= ${_IMAGES_SCR:S/.scr$/.pdf/} IMAGES_SCR_TXT= ${_IMAGES_SCR:S/.scr$/.txt/} IMAGES_PIC_PNG= ${_IMAGES_PIC:S/.pic$/.png/} IMAGES_PIC_EPS= ${_IMAGES_PIC:S/.pic$/.eps/} IMAGES_PIC_PDF= ${_IMAGES_PIC:S/.pic$/.pdf/} IMAGES_GEN_PDF+= ${IMAGES_PIC_PDF} ${IMAGES_SCR_PDF} CLEANFILES+= ${IMAGES_GEN_PNG} ${IMAGES_GEN_EPS} ${IMAGES_GEN_PDF} CLEANFILES+= ${IMAGES_SCR_PNG} ${IMAGES_SCR_EPS} ${IMAGES_SCR_TXT} CLEANFILES+= ${IMAGES_PIC_PNG} ${IMAGES_PIC_EPS} ${_IMAGES_PIC:S/.pic$/.ps/} IMAGES_PNG= ${_IMAGES_PNG} ${IMAGES_GEN_PNG} ${IMAGES_SCR_PNG} ${IMAGES_PIC_PNG} IMAGES_EPS= ${_IMAGES_EPS} ${IMAGES_GEN_EPS} ${IMAGES_SCR_EPS} ${IMAGES_PIC_EPS} IMAGES_TXT= ${_IMAGES_TXT} ${IMAGES_SCR_TXT} .if ${.OBJDIR} != ${.CURDIR} LOCAL_IMAGES= ${IMAGES:S|^|${.OBJDIR}/|} CLEANFILES+= ${LOCAL_IMAGES} .if !empty(_IMAGES_PNG) LOCAL_IMAGES_PNG= ${_IMAGES_PNG:S|^|${.OBJDIR}/|} .endif .if !empty(_IMAGES_EPS) LOCAL_IMAGES_EPS= ${_IMAGES_EPS:S|^|${.OBJDIR}/|} .endif .if !empty(_IMAGES_TXT) LOCAL_IMAGES_TXT= ${_IMAGES_TXT:S|^|${.OBJDIR}/|} .endif .else LOCAL_IMAGES= ${IMAGES} LOCAL_IMAGES_PNG= ${_IMAGES_PNG} LOCAL_IMAGES_EPS= ${_IMAGES_EPS} LOCAL_IMAGES_TXT= ${_IMAGES_TXT} .endif LOCAL_IMAGES_PNG+= ${IMAGES_GEN_PNG} ${IMAGES_SCR_PNG} ${IMAGES_PIC_PNG} LOCAL_IMAGES_EPS+= ${IMAGES_GEN_EPS} ${IMAGES_SCR_EPS} ${IMAGES_PIC_EPS} LOCAL_IMAGES_TXT+= ${IMAGES_SCR_TXT} # The default resolution eps2png (82) assumes a 640x480 monitor, and is too # low for the typical monitor in use today.
