Could you post some samples to illustrate?
Try this: Code: convert -density 300 2008 gmc sierra truck manual myfile.
Is there way to 0-pad the output file names to g etc?
It's not clear what you mean by "quality loss".To create thumbnail, the image just needs to be scaled down using either of the 'scale 'thumbnail' or 'resize' option.Pdfimages does not do the same thing that convert does when given a PDF as input.Pdfimages looks through the PDF for downgrade firmware 04.03 13 g embedded bitmap images and exports each one to a file.But your PDF was probably made for print, uisng higher DPI (300 would be pretty much standard).Edit: Just to explain the difference between image quality in your PDF files, and the quality of output images.Pdf2 g, the 2 in the bracket indicates the index of the page.Install, on ubuntu install it by typing the following in a terminal sudo apt-get install imagemagick, for windows get the binaries from the website.The delay parameter defines the delay of animation.
I convert a pdf file to jpg images by using ImageMagick like this: convert -density 600 foo.
For as many pages as there are in the pdf file.
It supports most image formats.
To get a single page from gm convert, add N (with N the page number starting at 0) to the PDF name, ie gm convert foo.This can be fixed using the 'density' option.Create gif animation of all pages."-quality" is then used to set the image compression quality for the final image, for JPG it's a range between 0 and 100, 100 being the best quality and lowest compression.Pdf11 g to get the 12th page from the PDF.Play around with the "density" setting, the images in your PDF have certain size and going above that will not improve image quality, quite the opposite.Perhaps cut the same section out of the poor quality and good quality versions (as a PNG to avoid further quality loss).Use a value of around 175 and the text should become clearer than before.Pdf2 g, the above will create a thumbnail image of height 300px and correct width according to aspect ratio of the original pdf.As a result, if what you have is a PDF that's just a wrapper around a series of bitmaps, pdfimages will do a much better job of extracting them, because it gets you the raw data at its original size.
