![]() ![]() Collapse AllThis method inserts an image from an imageBuffer (containing image data) into a PDF document and returns the index of the image.
|
| 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.
