It reads like English is not your native language while it is mine I failed every English course I took so we may have a hard time communicating.  Still I will try to have a go at it.

If the image does not have a 3:4 aspect ratio you must either crop away some of you image pixels to make it have a 3:4 aspect ratio or you must size your image to fit within the 3:4 aspect ratio area you want and have white border on one side or two borders  on opposite side of equal size.   I think from what you wrote what you want is to not crop any pixels and size the image onto a 3:4 aspect ratio canvas you want.  You can do that with two steps in Photoshop.

Step 1 menu File>Automate>Fit Image then in the Fit Image dialog enter one of your 3:4 aspect ratio like width 3000 and height 4000.

The Fit Image plug-in will resize your image to fit within an area that size if you image does not have a 3:4 aspect ratio the image will be resized smaller then width 3000 and height 4000 however the images longest side will either be 3000 or 4000 pixel in other words portrait will be either be 4000 pixel high but less the 3000 or 3000 pixel wide  with a height greatrer then 3000 pixels but less then 4000 pixel high.   Landscape will be 3000 pixels wide  and less the 3000 pixels high.

Step 2 menu Image>Canvas Size in the canvas size dialog leave the anchor point the center white square in the center if you want two borders or move it to one of the corner spots if you want a single border. Then enter the same sizes you used in the Fit Image dialog

When i run this script i my shirt image was croped

but i loss shirt image little bit in hands so i dont want crop in square image just i want canvas height  in 3/4 ratio

if (app.documents.length > 0) {

var docRef = app.activeDocument;
var WidthRatio = 3;
var HeightRatio = 4;
var boundTop;
var boundLeft;
var boundRight;
var boundBottom;

// Image's aspect ratio is greater than the desired ratio
// so crop out left and right areas of the Image
if ((docRef.width / docRef.height) > (WidthRatio/ HeightRatio))
{
boundTop = 0;
boundLeft = ((docRef.width - (docRef.height * (WidthRatio/HeightRatio))) / 2);
boundBottom = docRef.height;
boundRight = ((docRef.width + (docRef.height * (WidthRatio/HeightRatio))) / 2);
bounds = new Array(boundLeft,boundTop,boundRight,boundBottom);
docRef.crop(bounds);
}

// Image's aspect ratio is less than the desired ratio
// so crop out top and bottom areas of the Image
if ((docRef.width / docRef.height) < (WidthRatio/ HeightRatio))
{
boundTop = ((docRef.height - (docRef.width * (HeightRatio/WidthRatio))) / 2);
boundLeft = 0;
boundBottom = ((docRef.height + (docRef.width * (HeightRatio/WidthRatio))) / 2);
boundRight = docRef.width;
bounds = new Array(boundLeft,boundTop,boundRight,boundBottom);
docRef.crop(bounds);
}

// bounds = new Array(10, 10, app.activeDocument.width - 10, app.activeDocument.height - 10);
// docRef.crop(bounds);

boundTop = null;
boundLeft = null;
boundRight = null;
boundBottom = null;
WidthRatio = null;
HeightRatio = null;
docRef = null;

}


You have to do the fit image thing and then add canvas to make the canvas have a 3:4 aspect ratio.  The Fit Image Plug-in that ships with Photoshop is a Script in Photoshop Presets/scripts folder.  You can get the logic out of it to do the fit part.  The problem is you started the other thread

when i have above 3000 pixels image must resize 3000

when i have pixels between 2999 px to 2501 px i want to resize 2500 px

when i have pixels between 2499 px to 2001 px i want to resize 2000 px
when i have pixels between 1999 px to 1501 px i want to resize 1500 px

when i have pixels between 1499 px to 1101 px i want to resize 1000 px

don't change image when have 3000,2500,2000,1500,1100 pixels

This does not take into account an image orintation Portrait or Landscape and their aspect ratios. This thread your writting about Portrait Canvas with a Aspect ratio of 3:4  You must fit your images into this 3:4 Portrait Aspect Ratio Area. Your images will fall into  Four groups.  One its a portrait image with a 3:4 Aspect ratio. Two it a portrait with an aspect ratio that is wider then 3:4. Three its a Portrait Narower then 3:4. Four the image is a Landscape width is larger then height.  When these get fitted to 3:4 Aspect Ratio. The ones in the First group are perfect no bordere. Two will have small borders on top and bottom.  Three will have small borders on both sides.  Four will have large borders on top and bottom.

Script in the other thread should work if all your images have a portrait orintation for it first changes your non 3:4 aspect ratio portrait  images to have a 3:4 aspect Ratio by adding canvas then changes the Image size based on the image height given the sizes you wrote about is height.  This script may fail if an image has a landscape orintation my brain is telling me but it has been known to make errors. It may work could just be the cobwebs in my brain not letting me see the answer.
