The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Problems with Cropping Operation

Asked by spiritwithin in PHP Scripting Language, Web Images, Images and Photos

Tags:

Hello together,

i am working on an image processing automation tool for a printshop - having vast difficultes getting to a satisfying result with an IM -crop operation.

I have researched for hours, but i just can not get it right. I guess the problem is on my side - i am pretty certain, most people can tell me the correct command right away.

The goal is to resize and crop a given image to fit into a specific area on a template. If the resized image does not perfectly fit the target area, it must be cropped (in the vertical and horizontal center) so that it fits.

The commands i use are attached as a code snippet.

The result is always the same: the source image gets resized to fit either height or width of the area placed into. It does not get cropped. Therefore i always and up with my target image to contain the source image, but also thick white borders.

I would appreciate any help on that matter!

There is two more things i wondered about:

1.) The image quality of the result is not satisfying even though it never gets enlarged but rather shrinked and even though the source image is Hi-Resolution. I tried using -quality 100 -depth 8, but the result remains the same. Why?

2.) Is there a possibility to merge the two commands i use into one, so that imagemagick has not got to be launched twice - therefore saving time and cpu.

Thank you very much!
