I've tried googling for days, and test-installed nearly everything I have
found but cannot seem to locate the perfect program. I have a specific need. I need to be able to quickly and easily record the pixel locations of a great number of points within a picture. (I need to transfer many line drawings to a graph.) Is there some paint program that will not only tell me the exact cursor position (even mspaint does that) but that can at-the-click-of-a-button either put that information on the picture or transfer it to a text-type editor? Or is there a program that will allow me to enter text onto the picture at a very high zoom (while still displaying the pixel location coordinates)? MSpaint only allows one to enter text at normal zoom. Normal zoom is not accurate enough to locate the points I need, and "drawing" freehand text is painfully tedious if not near impossible at high zoom. Thank you kindly. -- Stu "If people put as much effort into their relationship with their mate as they do in being secretive about cheating on their mates, they wouldn't need to cheat." - U.N.Owen |

Ok, not execlty what you are looking for, but it just might work close enough for you: Photofiltre (http://www.photofiltre.com) What you could do: 1) load the picture with points. 2) if it not already so: convert to a non transparent RBG color picture (BMP or jpg) 3) choose the polygon tool (Aviable if you have selected the selection tool) 4) now trace the pixels you wnt by clicking on the exact location. 5) connect the last pont with the first one. 6) now you have a selction. Choose menu "Selection" >> "save Shape" 7) save the selection whereever you want. 8) go to the location you saved the selection 9) rename the file the file to .txt 10) The file contains a set of coordinates on each line, seperation the x and y coordinates with a ";" The first line tells you how many points there are. Now you can import the file in excel, or with find & replace make a cvs file out of it 2 points to remember: 1) The coordinates are relative of each other, (meaning the most left point is always 0 and the most upperpoint is also 0) so you might need to add a number on each coordinate. Just play around with it. You could also check into html image map editors, they coudl do about the same thing. MightyKitten |

On 09 Feb 2005 I could have sworn I heard MightyKitten sing a little
song and the words went something like this: > Ok, not execlty what you are looking for, but it just might work close > enough for you: > > Photofiltre (http://www.photofiltre.com) > > What you could do: > 1) load the picture with points. > 2) if it not already so: convert to a non transparent RBG color > picture (BMP or jpg) > 3) choose the polygon tool (Aviable if you have selected the selection > tool) 4) now trace the pixels you wnt by clicking on the exact > location. 5) connect the last pont with the first one. > 6) now you have a selction.
