# ESP_IMAGE_EFFECTS
2+
3+
ESP Image Effects (ESP_IMGFX) is an image processing engine that integrates basic functions such as rotation, color space conversion, scaling, cropping, and more. It serves as one of the core components of Espressif's audio and video development platform. The ESP Image Effects module undergoes deep reconstruction of underlying algorithms, combined with efficient memory management and hardware acceleration, achieving the triple characteristics of high performance, low power consumption, and low memory usage. Additionally, each image processing function adopts a consistent API architecture design, reducing the learning cost for users and facilitating rapid development. This engine is widely applicable in various fields, including the Internet of Things, smart cameras, industrial vision, and more.

# FAQ
63+
64+
---
65+
### 1. Why is image data size alignment and address alignment recommended?
66+
- Image data size alignment and address alignment are recommended for hardware compatibility and performance optimization.
67+
- Alignment improves cache efficiency, reducing memory access latency and enhancing overall performance.
68+
- SIMD instruction sets, such as those requiring data size alignment to 16 bytes, benefit from alignment.
69+
---
70+
71+
### 2. Why Concurrent Access to `esp_imgfx_*_set_cfg` and `esp_imgfx_*_process` is Prohibited？
72+
1. **Reason**
73+
- Modifying configuration parameters with `esp_imgfx_*_set_cfg` directly impacts `esp_imgfx_*_process`, making concurrent access unsafe in multi-threaded environments.
74+
2. **Solution**
75+
- Ensure atomicity between configuration updates and processing in multi-threaded scenarios by using mutexes or atomic operations.
76+
---
77+
78+
### 3. Reasons for `esp_imgfx_*_process` Returning `ESP_IMGFX_ERR_DATA_LACK`
79+
1. **Reason**
80+
- Input image buffer size is smaller than configured requirements, causing data lack errors (e.g., mismatch between configured 1920x1080 and input buffer size of 1920x720).
81+
2. **Solution**
82+
- Obtain required input dimensions with `esp_imgfx_get_image_size` and allocate sufficient data buffers accordingly.
83+
84+
---
85+
86+
### 4. Reasons for `esp_imgfx_*_process` Returning `ESP_IMGFX_ERR_BUFF_NOT_ENOUGH`
87+
1. **Reason**
88+
- Output image buffer size is smaller than configured requirements, leading to buffer not enough errors (e.g., configured for 1920x1080 but output buffer allocated for 1920x720).
89+
2. **Solution**
90+
- Pre-calculate output dimensions with `esp_imgfx_get_image_size` to match requirements and adjust buffer sizes accordingly.
91+
92+
---
93+
94+
### 5. Can the configuration parameters be reset?
95+
Yes, users can reset the configuration parameters by calling esp_imgfx_*_set_cfg. After that, esp_imgfx_*_process should be executed with the updated configuration.
96+
97+
---
98+
99+
### 6. What's reason of the build error `If use esp32p4, please use idf v5.3.`?
100+
1. **Reason**
101+
"Currently, compilers above version 5.3 have a compatibility issue, so P4 must be compiled with version 5.3. This will be fixed in a future update."
102+
2. **Solution**
103+
- Use idf5.3
