you wrote about comparing unlike programs,

and I asked,

can you clarify this for me - suppose I have a set of purposes, e.g.
altering color, inserting text, cropping, what have you; is it
unreasonable to compare 'different animals' in respect of ease of use
and quality of results in relation to specific ends like this?

(btw I compare apples to oranges all the time and indeed I prefer one
to the other. I don't call them both 'citrus fruit' though, I do call
them 'fruit' or food (actually, breakfast).)

why can't we compare "different animals" according to specific ends?

you replied that

It depends on the specific ends. Then decide on the type of tool you wish to use. Once the type of tool is selected, then compare the different versions of that type tool.

and here we agree.

then you wrote:

Let's say you want to disassemble an engine. How about a '57 Chevy? What kind of tool do you want to use?

The first is to select the correct tools. Metric? Whitworth? SAE? The first two are obviously are not the right solution. They won't work worth a hoot. You can force them, but it would be a PITA to use.

Which type of SAE tool? Wrench? Ratchet and sockets? Air tools and sockets? You decide on air tools and sockets. Now is when you compare the tools. Who makes the best air tool, for you, to do the job. Snap-on? Cleveland Pneumatic? Mac? MacTool? Cornwell?

Now you have a valid basis on which to compare tools, as the all do the same basic job in the same manner. Compressed air to turn the sockets to remove nuts and bolts.

That does not mean the air tool is always the best solution. Sometimes the wrench is the best solution.

let me interrupt the 'car talk'; you take back with one hand what you gave with the other. we can compare things according to our 'specific ends'. but that doesn't imply that our specific ends always require 'the best solution'! good enough is often good enough.

put another way, the 'the best solution' may not require including the optimally appropriate selection of tools.

we could have other ends that don't require this kind of optimality. this is usually the case for casual users of image programs and of other things like selection of car or place to have dinner.

And of all the variations of wrenches available, it might be a more specific wrench, an angle head wrench for example, is the best choice.

If you're specific end is to manipulate individual pixels in a bitmapped graphic, you use an image editor. You don't use a vector drawing program for that. Years ago, I used a couple of programs that claimed to do both, and in the end they did neither very well.

if your specific end includes this sort of optimality, yes; otherwise not so much. I'm not sure how this optimality condition slipped in.

This is where you need to know what kind of specific tools are out there. In the case of computers, what types of software is available, and a general idea of their capabilities.

In your scenario, your first decision is what kind of graphic image is it? Bitmapped or vector? (In they auto example, what's the measurement system used? Metric, Whitworth, or SAE.) If bitmapped, you're changing individual pixels. If vector, you're changing areas. They are different situations, requiring different tools.

A bitmapped image is a painting. A vector graphic is your car. Would you use a spray can to touch up your painting? A paint brush to paint your car? Although, I knew a guy that did that!

Here's an example:

I've a friend who wanted to take a picture, place numbers over it and create a clock face. The only software she knew about was Photoshop Essentials. And I don't know how much time she'd spent on the project with no success. But she was frustrated.

After getting details from her, I did the job for her in 15 minutes in Inkscape, learning how to do it at the same time.

She had never bothered to learn what other computer tools were out there, and what they were capable of.

yes, it's good to know different tools. of course not _every_ use of some suboptimal tool causes hours of wasted effort, may even spare effort.

this all was a bit of a digression from my question why we cannot compare 'different animals'. seems we can.
