I've got something fairly simple I want to do.
I'm using ImageMagick to convert some PDF to files to PNG images, and I'm experiencing some quality problems because the generated image has very low quality.
I played with the density, resample, interpolate and filter flags of the convert command, but I did not manage in having an high quality image like I would make a screenshot from a PDF reader (which preserve the vectorial quality of the PDF
I can't help with you immediate issue, but I have used the ffmpeg library in my own programs before. I learned just enough to do what I needed to do.If practical - or particularly if you will do this type of this more than once, and you know some C - you may want to write a small program that does this all in one pipeline rather than converting the entire video to images, imagemagick ea

Hi all,
Quick question about the quality of images on my HOX.
They are absolutely terrible, for a HOX, especially when one of their major selling points was the apparantly, amazing camera?
The quality of images out doors, is acceptable, but again for a camera such as the HOX I think they should be better.
But indoors, they are almost un-viewable they are that bad.
Im no camera expe
I am familiar with convert-resize % for decreasing a size by percentage but what is the command to increase an image from say 700 pixels to 800 pixels??? Horizontal width should resize, too. I need to preserve the overall quality and look of the image as best as possible.

Mogrify -resize geometry
that appears to be what I need to resize the images.
Wherever there is data, there shall be analytics.
