TCustomImageList.WriteData procedure

Member of TCustomImageListpublicIn unit ImgList

Writes image data for the default resolution to a stream.

Declaration

pascal
procedure WriteData(AStream: TStream); virtual

Arguments

AStream

Stream used to store the image data.

Description

WriteData is a procedure used to write the image data for the default resolution to the stream specified in AStream. WriteData calls GetResolution using the value in Width to retrieve the default image resolution. The WriteData method in TCustomImageListResolution is called to perform the write operation using the specified stream.

Data compression is enabled when writing image data for the resolution. Data compression was not enabled in previous LCL versions to maintain compatibility with earlier versions of Lazarus. That backward compatibility is no longer possible with image compression enabled.

Use WriteAdvData to write image data for all resolutions in the image list.

Use ReadData to read image data from a stream.

Image compression was enabled as a default in revision 62583, and will be included in Lazarus versions after 2.0.6.
