Good day Radaee. Please tell me, there was a need to display landscape thumbnails, but the place should be reserved, as in the picture of thumbnails 5 and 6.

tell me in which method this can be fixed. Thanks!

The layout is measured in PDFViewThumb.vLayout, the default behavior is to calculate the scale factor based on the thumbnail max height and use the same scale factor for all pages.

You will need to calculate the landscape ones with different scale factor, and adjust the values passed to
m_pages[cur].SetRect(left, top, m_scale);

thanks, it turned out to reduce individual thumbnails, but now another problem has arisen: when a lot of these small thumbnails and scrolling starts flickering (disappears and reappears), can this be fixed or is it due to the distance between the thumbnails

Hi Radaee, there were 2 questions:
1. There is a document in thumbnail mode (380 pages - 380 thumbnails), on each thumbnail an additional frame is drawn around the perimeter, a rectangle under the page number and the number itself. The problem is that after scrolling, you must wait about 15 seconds before flipping the screen so that it does not hang.
2. There are thumbnails (I enclose the figure), when passing the upper border of the screen from A to B, everything on the screen disappears, when you reach point B and then everything restores



Help solve these problems, thanks.

We aren't able to replicate the issue with our testing documents.
could you provide us the pdf file you're using?
