Member Function Documentation

◆ setData()

void setData	(	[in] sequence< byte >	data,
		[in] IntegerBitmapLayout	bitmapLayout,
		[in] ::com::sun::star::geometry::IntegerRectangle2D	rect
	)
raises	(	com::sun::star::lang::IllegalArgumentException,
		com::sun::star::lang::IndexOutOfBoundsException
	)

Set raw data of a bitmap.

Set raw data of a bitmap, in the format as defined by getMemoryLayout(). With the given rectangle, a subset of the bitmap can be changed. If the internal data format's pixel are not integer multiples of bytes (i.e. if one pixel occupies less than a byte), the leftover content of the bytes at the right of each scanline is ignored and left unchanged in the bitmap. When setting subsets of the bitmap, the same scanline padding takes place as when the whole bitmap is changed.

When setting data on volatile bitmaps, always call isValid() before, and retrieve a new memory layout via getMemoryLayout(). At least under Windows, the memory layout can change for the same bitmap, if the user e.g. switches the screen resolution. Thus, this method will throw an IllegalArgumentException, if the memory layout changed between a call to getMemoryLayout() and setData().

Parameters

data	Data to set
bitmapLayout	Layout of the data to set. Must match this bitmap's current layout.
rect	Destination rectangle, within the bounds of the bitmap, to set the data in.

Exceptions

com::sun::star::lang::IndexOutOfBoundsException	if parts of the given rectangle are outside the permissible bitmap area.
com::sun::star::lang::IllegalArgumentException	if the given memory layout does not match this bitmap's layout, or if the given data sequence has too few or too many elements.

◆ setPixel()

void setPixel	(	[in] sequence< byte >	color,
		[in] IntegerBitmapLayout	bitmapLayout,
		[in] ::com::sun::star::geometry::IntegerPoint2D	pos
	)
raises	(	com::sun::star::lang::IllegalArgumentException,
		com::sun::star::lang::IndexOutOfBoundsException
	)

Set a single pixel of the bitmap with the given color value.

If the internal data format's pixel are not integer multiples of bytes (i.e. if one pixel occupies less than a byte), the color value is expected in the least significant bits of the single byte given as the color.

When setting data on volatile bitmaps, always call isValid() before, and retrieve a new memory layout via getMemoryLayout(). At least under Windows, the memory layout can change for the same bitmap, if the user e.g. switches the screen resolution. Thus, this method will throw an IllegalArgumentException, if the memory layout changed between a call to getMemoryLayout() and setPixel().
