Imagemagick - Best print quality from a TIF to JPG conversion.

162 New Member
I am working with a TIF to JPG conversion that will result in the JPG being printed from a web page. My issue is the final JPG image prints VERY blurry.

The TIF file that has the following settings,

Pixel Dimensions - 9600x7200
Document Size - 24x18 inches
Resolution - 400 px/in
File Size - 236 KB

When using the command
Expand|Select|Wrap|Line Numbers
  1. exec("convert plat.tif -density 300x300 -quality 100 plat.jpg");
the code takes 63 seconds to run. Is this normal?

Then i run
Expand|Select|Wrap|Line Numbers
  1. exec("convert plat.jpg -resize 792x612 -quality 100 plat_resize.jpg");
to reduce the JPG to the PX size i need. the code takes 73 seconds to run. Is this normal?

When plat_resize.jpg is viewed in Firefox using a standard <img src> tag the image looks not as good as the original TIF, but "OK". Though, my final output is to print the image and this is where my main problem is. The printed image looks blurry and unreadable. How can i get it to look as good or as close to the original TIF as possible?

Here are the files being used and generated.

Thank much for all the replies to come.

I've been fighting with this for three days. Can anyone give me a clue as to what I need to do to make this script work? Win98 (first edition), PHP 4.3.3, Imagemagick 5.5.7 Q8, PWS 4.0 If the line with the system(...) call is removed, the script runs as expected. Otherwise, the command is executed and the image conversion is done successfully, but no response is returned from the server. After that, no more pages will be served and a...

Hi all. I'm creating a web-based application that uses PHP, MySQL & Apache on a Windows platform. What I need to do is create images on the fly with either GD or ImageMagick, display them on the web browser and then save the file. The tricky part is the format of that saved file - it needs to be an EPS format. The image won't be anything terribly exciting - just some basic shapes (boxes, circles, etc) and some text. No fancy colors,...

I'm looking for a way to print stuff from my program. I have searched and searched for a way to print and the only thing I have found is PrintFORM which only takes a picture of the form and prints it in image quality which is really really bad quality. Is there any way to print the text off my form the way it looks and everything? Like how PrintForm prints but instead printing the text in "text quality" and the images in image quality? Im...

I am trying to use ImageMagick to create thumbnails on the fly - without having to save the image to a file. I have gotten it to work by using passthru($cmd, $retval), but I want to use something else that will give me the complete output returned as a string that I can convert to a GD lib image resource so I can verify the operation worked before sending the Content-type header for the image. This works:...

Hi to all!!! I'm trying to convert a pdf file into an image, for example JPG or PNG format, with ImageMagick. I use the command line. For example: convert header.pdf header.jpg. But I obtain a bad result. The jpg's quality is very low. Why? I tried to use - quality 100 option but there isn't improvement. I think also that this option isn't active for the pdf conversion to an image format or not? I need some good ideas :D... Thanks to...
