AddImageFromMemory

This method inserts an image from an imageBuffer (containing image data) into a PDF document and returns the index of the image.

Syntax

LONG AddImageFromMemory (
LPSTR imageBuffer,
LONG bufferSizeInBytes,
TxImageCompressionType compressionType
)

Parameters

imageBuffer

Image binary data buffer

bufferSizeInBytes

Size of the buffer in bytes

compressionType

Image compression type

Return value

This method returns the new image index. If there is more than one image in a buffer, then it returns the index of the most recently added image.

Remarks

The length of the memory buffer specified by the bufferSizeInBytes parameter and compressionType help determine the type of image.

The return value is an image identifier in the document's images collection and can be used in FlipImage, GetImageHeight, GetImageResolution, GetImageWidth, MakeImageGrayScale, MakeImageNegative, PlaceImageToCurrentPage, PDFPAGE_ShowImage.

Equivalent in new interface: IPDFDocument4::AddImageFromBuffer.
