Hi there,

when trying to open a large .jpg-Picture (dimensions around 10 000 x 7500 pixels) MP only shows black. I created various new test-files in paint with those dimensions (I attached a rather pretty one) and MP fails to display it, so I'm fairly certain it's the sheer amount of pixels that is causing the issue. I tried waiting, in case the processing of those huge images just takes a bit, but after several minutes the screen was still black. The Thumbnails for the files are being created flawlessly, though.

MediaPortal.log (DEBUG-Verbosity) shows only this (MediaPortal-Error.log has no related entries):

Is this a (known) limitation of the plugin?

    The same thing, starting with 1.10, and ending with 1.14 ... big picture does not show. In memory of about 8000 or more in width...

    I have the same problem sometimes with images from my new digital camera (24 Mpix). But when I restart MePo 1.12 it usually works. I have made some backdrop images even for my "pictures" screen and the big ones seem not to be displayed all the time and I get a black screen until the following (smaller?) image is displayed. It seems like MePo is "causing" the problem over time. Is there a buffer or something which is not re-freshed???

    If the picture is more than 10,000 in width, the media portal does not show it at all. Rebooting does not help waiting for 30min as well. Just a black screen.

    works @ my PC. What amount of vidoe memory do you have? this picture in decoded form takes over 200MBytes, so you need at least 512 MBytes of memory (shared or dedicated).

    But I have the picture size about 30MB
    Same for me and the pictures are less than 15MB.
    don't forget- the images will be decompressed in memory, so count width*height*3 bytes per pixel.
    I get the exception
    System.OutOfMemoryException: Out of memory.
    at System.Drawing.Graphics.CheckErrorStatus(Int32 status)
    at System.Drawing.Graphics.DrawImage(Image image, Int32 x, Int32 y, Int32 width, Int32 height)
    at System.Drawing.Graphics.DrawImage(Image image, Rectangle rect)

    on line
    C#:
    g.DrawImage(theImage, new Rectangle(xpos, ypos, iWidth, iHeight));
    for images like 20k*15k, and i assume it is because this picture takes over 900 MBytes and thus doesn't fit into my 1GB graphic memory.
