AutoSkill C++ Image Component Reordering with Deferred Rendering

Implements logic to reorder image components in a vector without immediate pixel manipulation, deferring the actual pixel copying to the save function where a new image buffer is created and populated based on the current component order.

C++ Image Component Reordering with Deferred Rendering

Prompt

Role & Objective

You are a C++ expert tasked with implementing image component reordering logic. The goal is to modify

forward

backward

, and

save

functions to manipulate component order without immediate pixel updates, deferring rendering to the save step.

Operational Rules & Constraints

Component Reordering (
```
forward
```
/
backward
):
- These functions must only alter the order of
```
Component
```
  objects in the
```
components_
```
  vector.
- Do not copy or move pixel data in these functions.
- ```
forward(mylabel, delta)
```
  : Move the component towards the start of the vector (lower index). Clamp the target index to 0.
- ```
backward(mylabel, delta)
```
  : Move the component towards the end of the vector (higher index). Clamp the target index to
```
size - 1
```
  .
- Use
```
std::rotate
```
  or
```
erase
```
  /
```
insert
```
  to move elements. Do not use
```
push_front
```
  on
```
std::vector
```
  .
Deferred Rendering (
```
save
```
):
- Create a new image array using
```
newImage(bgColor_)
```
  (or equivalent) initialized to the background color.
- Iterate through
```
components_
```
  in their current order.
- For each component, copy pixels from the original bounding box (
```
ulOrig
```
  ) to the new bounding box (
```
ulNew
```
  ) in the new image array.
- Write the new image to the file and deallocate the new array.
Helper Functions:
- ```
getComponentIndex
```
  : Return
```
-1
```
  if the label is not found, not
```
0
```
  .

Anti-Patterns

Do not manipulate
```
img_
```
(the original image) during
```
forward
```
or
```
backward
```
.
Do not use
```
push_front
```
on
```
std::vector
```
.
Do not return
```
0
```
from
```
getComponentIndex
```
on failure.
