Script auto make selection snap to added guides line

问题

I need a script for Photoshop which can create a square or rectangular selection (use rectangular marquee tool) and it will snap to the guides line, no matter the position of the guides, sometimes with 2 guides sometimes I will add 4 guides. Or it'll be ok if the script make a selection from the guide to the bottom of the photo.

以下是一些其他选项，我期望的：
创建选择 1
创建选择 2

以下是翻译好的部分：

首先，应该理解 Stack Overflow 不是代码编写服务。此外，你应该包括一个代码的最小可复现示例。

好的，继续你的问题：

你可以获取选择区域的矩形坐标，只需将水平或垂直参考线添加到这些边界上。参考线的代码是从脚本监听器中提取的。

英文:

First up, should understand that SO is not a code writing service. Also, you should include a minimal, reproducible example of code.

Ok, on with your question:

You can get the rectangular coordinates of a selection with selection bounds.
It's just a case of adding a horizontal or vertical guide to those bounds:
The code for the guides was taken from the script listener.

  1. // Switch off any dialog boxes
  2. displayDialogs = DialogModes.ERROR; // OFF 
  3. // Top, Left, Bottom, Right
  4. var sb = get_selection_bounds();
  5. if (sb != undefined)
  6. {
  7. add_guide(sb[0], "v");
  8. add_guide(sb[1], "h");
  9. add_guide(sb[2], "v");
  10. add_guide(sb[3], "h");
  11. }
  12. // Set Display Dialogs back to normal
  13. displayDialogs = DialogModes.ALL; // NORMAL
  14. function add_guide(dist, dir)
  15. {
  16. var vert = true;
  17. if (dir.toLowerCase() == "v") vert = true;
  18. if (dir.toLowerCase() == "h") vert = false;
  19. var idMk = charIDToTypeID( "Mk  " );
  20. var desc1583 = new ActionDescriptor();
  21. var idNw = charIDToTypeID( "Nw  " );
  22. var desc1584 = new ActionDescriptor();
  23. var idPstn = charIDToTypeID( "Pstn" );
  24. var idPxl = charIDToTypeID( "#Pxl" );
  25. desc1584.putUnitDouble( idPstn, idPxl, dist );
  26. var idOrnt = charIDToTypeID( "Ornt" );
  27. var idOrnt = charIDToTypeID( "Ornt" );
  28. if (vert == true)
  29. {
  30. var idVrtc = charIDToTypeID( "Vrtc" );
  31. desc1584.putEnumerated( idOrnt, idOrnt, idVrtc );
  32. }
  33. else
  34. {
  35. var idHrzn = charIDToTypeID( "Hrzn" );
  36. desc1584.putEnumerated( idOrnt, idOrnt, idHrzn );
  37. }
  38. var idKnd = charIDToTypeID( "Knd " );
  39. var idKnd = charIDToTypeID( "Knd " );
  40. var idDcmn = charIDToTypeID( "Dcmn" );

这是创建矩形选择的脚本：

  1. // 获取活动文档
  2. var doc = app.activeDocument;
  4. // 获取参考线
  5. var guides = doc.guides;
  7. // 获取第一个水平和垂直参考线
  8. var hGuide1 = guides[0];
  9. var vGuide1 = guides[1];
  11. // 获取第二个水平和垂直参考线（如果存在）
  12. var hGuide2 = guides.length > 2 ? guides[2] : null;
  13. var vGuide2 = guides.length > 3 ? guides[3] : null;
  15. // 根据参考线计算选择区域的坐标
  16. var x1 = vGuide1.direction == Direction.VERTICAL ? vGuide1.coordinate : hGuide1.coordinate;
  17. var y1 = hGuide1.direction == Direction.HORIZONTAL ? hGuide1.coordinate : vGuide1.coordinate;
  18. var x2 = vGuide2 != null && vGuide2.direction == Direction.VERTICAL ? vGuide2.coordinate : doc.width.as("px");
  19. var y2 = hGuide2 != null && hGuide2.direction == Direction.HORIZONTAL ? hGuide2.coordinate : doc.height.as("px");
  21. // 创建矩形选择
  22. doc.selection.select([[x1, y1], [x2, y1], [x2, y2], [x1, y2]], SelectionType.REPLACE, 0, false);

要运行它，请创建一个扩展名为jsx的文件，例如：script.jsx，然后依次选择“文件->脚本->浏览...”并选择script.jsx文件。

英文:

Here script that creates a rectangular selection:

  1. // Get the active document
  2. var doc = app.activeDocument;
  4. // Get the guides
  5. var guides = doc.guides;
  7. // Get the first horizontal and vertical guides
  8. var hGuide1 = guides[0];
  9. var vGuide1 = guides[1];
  11. // Get the second horizontal and vertical guides (if they exist)
  12. var hGuide2 = guides.length > 2 ? guides[2] : null;
  13. var vGuide2 = guides.length > 3 ? guides[3] : null;
  15. // Calculate the selection coordinates based on the guides
  16. var x1 = vGuide1.direction == Direction.VERTICAL ? vGuide1.coordinate : hGuide1.coordinate;
  17. var y1 = hGuide1.direction == Direction.HORIZONTAL ? hGuide1.coordinate : vGuide1.coordinate;
  18. var x2 = vGuide2 != null && vGuide2.direction == Direction.VERTICAL ? vGuide2.coordinate : doc.width.as("px");
  19. var y2 = hGuide2 != null && hGuide2.direction == Direction.HORIZONTAL ? hGuide2.coordinate : doc.height.as("px");
  21. // Create the rectangular selection
  22. doc.selection.select([[x1, y1], [x2, y1], [x2, y2], [x1, y2]], SelectionType.REPLACE, 0, false);

To run it, create a file with the extension jsx. For example: script.jsx

Then File->Scripts->Browse... select the file script.jsx
