class wx.richtext.RichTextImageBlock(Object)

Possible constructors:

RichTextImageBlock()

RichTextImageBlock(block)

This class stores information about an image, in binary in-memory form.

Methods

---

__init__(self, *args, **kw)

Overloaded Implementations:

---

__init__ (self)

Constructor.

---

__init__ (self, block)

Copy constructor.

Parameters:block (wx.richtext.RichTextImageBlock) –

---

---

Clear(self)

Clears the block.

---

Copy(self, block)

Copy from block.

Parameters:block (wx.richtext.RichTextImageBlock) –

---

DoMakeImageBlock(self, image, imageType)

Makes the image block.

Parameters:

• image (wx.Image) –
• imageType (BitmapType) –

Return type:

bool

---

GetData(self)

Returns the raw data.

Return type:int

---

GetDataSize(self)

Returns the data size in bytes.

Return type:int

---

GetExtension(self)

Gets the extension for the block’s type.

Return type:string

---

GetImageType(self)

Returns the image type.

Return type: wx.BitmapType

---

Init(self)

Initialises the block.

---

IsOk(self)

Returns True if the data is not None.

Return type:bool

---

Load(self, image)

Parameters:image (wx.Image) – Return type:bool

---

MakeImageBlock(self, *args, **kw)

Overloaded Implementations:

---

MakeImageBlock (self, filename, imageType, image, convertToJPEG=True)

Load the original image into a memory block.

If the image is not a JPEG, we must convert it into a JPEG to conserve space. If it’s not a JPEG we can make use of image, already scaled, so we don’t have to load the image a second time.

Parameters:

• filename (string) –
• imageType (BitmapType) –
• image (wx.Image) –
• convertToJPEG (bool) –

Return type:

bool

---

MakeImageBlock (self, image, imageType, quality=80)

Make an image block from the wx.Image in the given format.

Parameters:

• image (wx.Image) –
• imageType (BitmapType) –
• quality (int) –

Return type:

bool

---

---

MakeImageBlockDefaultQuality(self, image, imageType)

Uses a wx.Image for efficiency, but can’t set quality (only relevant for JPEG)

Parameters:

• image (wx.Image) –
• imageType (BitmapType) –

Return type:

bool

---

Ok(self)

Return type:bool

---

static ReadBlock(*args, **kw)

Overloaded Implementations:

---

ReadBlock (stream, size)

Implementation.

Allocates and reads from a stream as a block of memory.

Parameters:

• stream (wx.InputStream) –
• size (int) –

Return type:

int

---

ReadBlock (filename, size)

Allocates and reads from a file as a block of memory.

Parameters:

• filename (string) –
• size (int) –

Return type:

int

---

---

ReadHex(self, stream, length, imageType)

Reads the data in hex from a stream.

Parameters:

• stream (wx.InputStream) –
• length (int) –
• imageType (BitmapType) –

Return type:

bool

---

SetData(self, image)

Parameters:image (int) –

---

SetDataSize(self, size)

Sets the data size.

Parameters:size (int) –

---

SetImageType(self, imageType)

Sets the image type.

Parameters:imageType (BitmapType) –

---

Write(self, filename)

Writes the block to a file.

Parameters:filename (string) – Return type:bool

---

static WriteBlock(*args, **kw)

Overloaded Implementations:

---

WriteBlock (stream, block, size)

Writes a memory block to stream.

Parameters:

• stream (wx.OutputStream) –
• block (int) –
• size (int) –

Return type:

bool

---

WriteBlock (filename, block, size)

Writes a memory block to a file.

Parameters:

• filename (string) –
• block (int) –
• size (int) –

Return type:

bool

---

---

WriteHex(self, stream)

Writes the data in hex to a stream.

Parameters:stream (wx.OutputStream) – Return type:bool
