large pictures can't be displayed (1 Viewer)

[bta489]

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???

But when I restart MePo 1.12 it usually works.

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.

@HomeY
Are there any ideas?

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).

 

[ajs]

so you need at least 512 MBytes of memory (shared or dedicated).

1Gb ... But I have the picture size about 30MB ...

 

[LennyW]

Same for me and the pictures are less than 15MB.

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)

on line

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.

XNView and Windows Viewer It shows them properly on any computer, my examples
