PXC_AddImageFromHBITMAP doesn't release memory

[ondrejb]

Hello,
I noticed that the PXC_AddImageFromHBITMAP consumes (and doesn't release) quite large amount of memory - see the attached project.
The memory consumption increases with image size: for the small image in the attached project it takes about 5MB, for A4/300dpi it consumes about 40MB.

When using the PXC_AddImageW instead of PXC_AddImageFromHBITMAP, the memory usage is OK.

Steps to reproduce behavior:
1. Run the attached application
2. Create PDF by clicking the Create PDF button
3. Each time the button is clicked, the memory usage of the application is increased for about 5 MB (check in the Task Manager)

My configuration:
* PDF-XChange PRO 4 SDK, build 4.0.0.152
* VB.NET 2008, ver. 9.0.30729.1 SP (with SP1)
* Win Vista Business SP1

PXC_AddImageFromHBITMAP does not free bitmap handle passed to it, so it must be released in your code. See Remarks section in Bitmap::GetHbitmap method help - http://msdn.microsoft.com/en-us/library/1dz311e4.aspx Also see attached corrected sample. By the way, your code is less effective than using PXC_AddImageW or PXC_AddImageFromImageXChangePage - because of about three times larger memory usage.

Thank you!

Ad code efficiency - this was just a test/demo project; the real app inserts into PDF scanned images...
