# CGPSConverter

An opaque data type used to convert PostScript data to PDF data.

```
class CGPSConverter
```

## Overview

The PostScript data is supplied by a data provider and written into a data consumer. When you create a PostScript converter object, you can supply callback functions to invoke at various stages of the conversion process.

## Topics

### Initializers

[`init(info:callbacks:options:)`](/documentation/CoreGraphics/CGPSConverter/init(info:callbacks:options:))

Creates a new PostScript converter.

### Miscellaneous Functions

[`convert(_:consumer:options:)`](/documentation/CoreGraphics/CGPSConverter/convert(_:consumer:options:))

Uses a PostScript converter to convert PostScript data to PDF data.

[`isConverting`](/documentation/CoreGraphics/CGPSConverter/isConverting)

Checks whether the converter is currently converting data.

[`abort()`](/documentation/CoreGraphics/CGPSConverter/abort())

Tells a PostScript converter to abort a conversion at the next available opportunity.

### Instance Properties

[`isConverting`](/documentation/CoreGraphics/CGPSConverter/isConverting)

Checks whether the converter is currently converting data.

### Type Properties

[`typeID`](/documentation/CoreGraphics/CGPSConverter/typeID)

Returns the Core Foundation type identifier for PostScript converters.

### Instance Methods

[`abort()`](/documentation/CoreGraphics/CGPSConverter/abort())

Tells a PostScript converter to abort a conversion at the next available opportunity.

[`convert(_:consumer:options:)`](/documentation/CoreGraphics/CGPSConverter/convert(_:consumer:options:))

Uses a PostScript converter to convert PostScript data to PDF data.

### Callbacks

[`CGPSConverterCallbacks`](/documentation/CoreGraphics/CGPSConverterCallbacks)

A structure for holding the callbacks provided when you create a PostScript converter object.

[`CGPSConverterBeginDocumentCallback`](/documentation/CoreGraphics/CGPSConverterBeginDocumentCallback)

Performs custom tasks at the beginning of a PostScript conversion process.

[`CGPSConverterEndDocumentCallback`](/documentation/CoreGraphics/CGPSConverterEndDocumentCallback)

Performs custom tasks at the end of a PostScript conversion process.

[`CGPSConverterBeginPageCallback`](/documentation/CoreGraphics/CGPSConverterBeginPageCallback)

Performs custom tasks at the beginning of each page in a PostScript conversion process.

[`CGPSConverterEndPageCallback`](/documentation/CoreGraphics/CGPSConverterEndPageCallback)

Performs custom tasks at the end of each page of a PostScript conversion process.

[`CGPSConverterProgressCallback`](/documentation/CoreGraphics/CGPSConverterProgressCallback)

Reports progress periodically during a PostScript conversion process.

[`CGPSConverterMessageCallback`](/documentation/CoreGraphics/CGPSConverterMessageCallback)

Passes messages generated during a PostScript conversion process.

[`CGPSConverterReleaseInfoCallback`](/documentation/CoreGraphics/CGPSConverterReleaseInfoCallback)

Performs custom tasks when a PostScript converter is released.
