Hello,
Maybe you could use ImageMagick to show one page of the pdf as an image ? This is what I have implemented on my project : first page of pdf files can be pre-viewed before user uploads the whole file (if needed). In your case, pre-viewing could be parametrized to show page ‘n’ of the pdf file, probably. In my project, pre-viewing image is generated when pdf file is uploaded and saved by admin in myproject/media/files directory. Once pdf files are in media directory, users can preview those pdf files and tnen upload them, if needed (only first page can be pre-viewed by user. This is an implementation choice). http://www.imagemagick.org/script/index.php <http://www.imagemagick.org/script/index.php> Implementation principles/credit can be found here : http://www.yaconiello.com/blog/auto-generating-pdf-covers/ <http://www.yaconiello.com/blog/auto-generating-pdf-covers/> I am attaching the signals file_post_save file_pre_save, for information. Cheers. Django 1.8 Python 3.4 Note : to install ImageMagick: sudo apt-get install libmagickwand-dev imagemagick libmagickcore-dev The convert command allows to convert any page of pdf file into png image (for instance), eg : convert -thumbnail 1280 test.pdf[0] test_1280.png Several parameters exist to tune image quality (in my case, need to use density, trim and quality). *models.p**y* […] ########### # SIGNALS # ########### from django.db.models.signals import post_save, pre_delete from django.dispatch import receiver from myproject.settings import MEDIA_ROOT import subprocess # What to do after a File is saved - receiver definition def file_post_save(sender, instance=False, **kwargs): # This post save function creates a thumbnail for the File file = File.objects.get(pk=instance.pk) command = "convert -density 300 -trim -thumbnail %s %s%s[0] -quality 100 %s%s" % (file.thumbnail_size, MEDIA_ROOT, file.file, MEDIA_ROOT, file.thumbnail) proc = subprocess.Popen(command, shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, ) stdout_value = proc.communicate()[0] post_save.connect(file_post_save, sender=File, dispatch_uid="file_post_save_uid") # What to do before a File is deleted - receiver definition def file_pre_delete(sender, instance=False, **kwargs): # This pre delete function deletes file and thumbnail from media directory file = File.objects.get(pk=instance.pk) command = "rm %s%s %s%s" % (MEDIA_ROOT, file.file, MEDIA_ROOT, file.thumbnail) proc = subprocess.Popen(command, shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, ) stdout_value = proc.communicate()[0] pre_delete.connect(file_pre_delete, sender=File, dispatch_uid="file_pre_delete_uid") -- You received this message because you are subscribed to the Google Groups "Django users" group.
