## **Обзор**

The [aspose.slides.lowcode](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/) module provides helper classes for common presentation operations. These helpers wrap frequently used object-model workflows in focused methods, so you can convert or merge files, collect shapes, and remove unused content with less code.

Low-code helpers are most useful when the operation applies to an entire file or presentation and the default workflow matches your requirements. Use the full [Aspose.Slides object model](https://reference.aspose.com/slides/ru/python-net/aspose.slides/) when you need fine-grained control over individual slides, masters, layouts, shapes, export settings, or relationships between presentation elements.

The following table summarizes the available helpers:

| Помощник | Для чего использовать |
| --- | --- |
| [Convert](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/convert/) | Конвертация презентации в другой формат с прямым вызовом file-to-file. |
| [Merger](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/merger/) | Объединение полных файлов презентаций одинакового формата. |
| [Collect](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/collect/) | Получение фигур из всей презентации для повторной обработки или анализа. |
| [Compress](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/compress/) | Удаление неиспользуемых мастеров и макетов и уменьшение данных встроенных шрифтов. |

## **Конвертация презентации**

Use [Convert.auto_by_extension](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/convert/auto_by_extension/) when the output file extension is sufficient to select the export format. The method opens the source presentation, determines the required format from the output path, and writes the result.

```python
import aspose.slides as slides

slides.lowcode.Convert.auto_by_extension("input.pptx", "output.pdf")
```

The [Convert](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/convert/) class also provides dedicated methods for PDF, SVG, JPEG, PNG, and TIFF output. Use the full object model when you need to inspect or modify the presentation before export or configure an export option that is not exposed by the selected helper. See [Convert Presentation](/slides/ru/python-net/convert-presentation/) for format-specific workflows and options.

## **Объединение презентаций**

Use [Merger.process](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/merger/process/) to combine complete presentation files with one call. The input presentations must have the same file format.

```python
import aspose.slides as slides

input_files = ["part-1.pptx", "part-2.pptx"]
slides.lowcode.Merger.process(input_files, "merged.pptx")
```

The helper is appropriate when all slides should be appended to one result without selecting or remapping them individually. Use the full object model when you need to merge selected slides, apply a destination master or layout, preserve sections explicitly, or reconcile different slide sizes. See [Merge Presentations](/slides/ru/python-net/merge-presentation/) for those scenarios.

## **Сбор фигур**

Use [Collect.shapes](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/collect/shapes/) when you need a collection of all shapes in a presentation. This is useful when the same set will be filtered, counted, or processed more than once.

```python
import aspose.slides as slides

with slides.Presentation("input.pptx") as presentation:
    shapes = slides.lowcode.Collect.shapes(presentation)

    for shape in shapes:
        print(f"{shape.name}: {type(shape).__name__}")
```

Use direct collection loops when traversal order, early exit, filtering before processing, or detailed parent-child control is important.

## **Сжатие содержимого презентации**

The [Compress](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/compress/) class can remove unused structural elements and reduce embedded font data:

- [Compress.remove_unused_layout_slides](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/compress/remove_unused_layout_slides/) removes layout slides that no normal slide references.
- [Compress.remove_unused_master_slides](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/compress/remove_unused_master_slides/) removes master slides that are no longer used.
- [Compress.compress_embedded_fonts](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/compress/compress_embedded_fonts/) removes unused characters from embedded fonts.

```python
import aspose.slides as slides

with slides.Presentation("input.pptx") as presentation:
    slides.lowcode.Compress.remove_unused_layout_slides(presentation)
    slides.lowcode.Compress.remove_unused_master_slides(presentation)
    slides.lowcode.Compress.compress_embedded_fonts(presentation)

    presentation.save("compressed.pptx", slides.export.SaveFormat.PPTX)
```

Remove unused layouts before unused masters so a master that becomes unreferenced after layout cleanup can also be removed. Save the optimized presentation to a new file if you may need the original masters, layouts, or complete embedded font data later. For more detail, see [Slide Master](/slides/ru/python-net/slide-master/) and [Embedded Font](/slides/ru/python-net/embedded-font/).

## **Часто задаваемые вопросы**

**Когда следует использовать low-code API вместо полной объектной модели?**

Use low-code helpers when a standard operation applies to a complete file or presentation and does not require detailed control over individual elements. Use the full object model when you need to select specific slides, control master and layout relationships, inspect intermediate state, or configure behavior that the helper does not expose.

**Можно ли с помощью Merger объединять презентации разных форматов файлов?**

No. [Merger.process](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/merger/process/) requires input presentations in the same format. Convert the input files to a common format first, for example with [Convert.auto_by_extension](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/convert/auto_by_extension/), and then merge the converted files.

**Что включает в себя Collect.shapes?**

[Collect.shapes](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/collect/shapes/) retrieves shapes from the presentation so they can be retained, filtered, counted, or traversed multiple times. Use direct collection loops when you need precise control over which slide types or nested objects are visited.

**Всегда ли Compress делает файл презентации меньше?**

Not necessarily. The result depends on whether the presentation contains unused layouts, unused masters, or embedded fonts with unused characters. If none of those are present, the corresponding [Compress](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/compress/) operations may not reduce the file size.

**Сохраняются ли изменения, сделанные Compress, автоматически?**

No. These helpers operate on the loaded [Presentation](https://reference.aspose.com/slides/ru/python-net/aspose.slides/presentation/) object in memory. After running [Compress](https://reference.aspose.com/slides/ru/python-net/aspose.slides.lowcode/compress/), call [Presentation.save](https://reference.aspose.com/slides/ru/python-net/aspose.slides/presentation/save/) to write the result.
