I decided to break the gbScroller app into two parts. The first is posted in the forum as gbClientCapture.
It captures the area under the transparent dialog client, merging each new capture into a horizontal image for subsequent scrolling. I've not yet written the scrolling app.
The area between the Toolbar and Statusbar is captured and merged into a horizontal image.

Some new features come to mind:
1. allow using the arrow keys to more accurately position the dialog
2. with transparency, the resize with a mouse ability is limited to the caption and toolbar. Not sure why but I know I don't like it.
Not a feature, but I notice there is a tiny gap between the caption and toolbar. I'm not sure why. I thought the toolbar by default would be positioned immediately next to the caption.
And, another thing, I tweaked the various dimensions to make sure the client area is captured, without overlapping the toolbar, statusbar and dialog borders. But it seems to me that I should have been able to do a more exact dimensioning of the capture positioning/size.
Here's how I envision this working.
1. Call up the electronic copy of the music (PDF in this example).
2. Place gbClientCapture over the first row of music (resize as needed)
3. Click "Copy"
4. Scroll the PDF upwards until the next row of music is under gbClientCapture (that should be easier than moving the dialog itself.
5. Click "Copy"
6. Repeat until all rows of music are captured and placed in the "merge.bmp" file.
In this example, the Adele music sheet PDF is displayed vertically in my browser. The gbClientCapture is positioned over the first row, ready for "Copy". Then, instead of moving the dialog to a new position, I scroll the PDF upwards until the next row of music is visible under the dialog client area. Repeat Copying untill all rows of music are captured. With each capture the "merge.bmp" file is updated to contain the most recent capture.
