I have a large number of jpg files that I need to ‘manipulate’ and then save as pdf files. The jpg files are images of line drawings.
I am using the Perl version of ImageMagick and all works well except…
The exception is the size of the pdf file. The pdf version of the image tends to be larger size on the disc than the jpg version.
However when I used the IRIS application the pdf image is typically a qurter or fifth of the size. IRIS cannot be used ‘automatically’ therefore this possible solution cannot be implemented.
I do not want to reduce the resolution of the image.
Can ImageMagick be used in a way to give a similar size reduction? If not are there other Perl based ‘tool’s that I can use to get the reduced size?
