2019-05-31 Thread Dmitriy Sedov 
when i use Image with big images, i use code like this:|
Image {
onSourceSizeChanged: {
if( sourceSize.width > 3264 )
sourceSize.width = 3264
if( sourceSize.height > 3264 )
sourceSize.height = 3264
}
cache: false
asynchronous: true

Re: [SailfishDevel] ListView , Image with large height and EGL errors (AL13N)

2019-05-31 Thread AL13N 

I actually did:

width: parent.width
asynchronous: true
cache: false
sourceSize.width: width

for this thing; the height it still like 8000 pixels high, even with 
width == the jolla1 pixel width.
thing is, i get black for those long images, and an EGL Texture error. 
short ones are done fine.


but, if i do the image on its own, then it works fine. so, it's 
something to do with the ListView and the way it instantiates it...

Those who don't like the idea of hardcoding 3264 (or any other number) 
in their code, can query GL_MAX_TEXTURE_SIZE instead:

I have a qml only app...

i found out experimentally that the limit is at 4096 for Y; but only in 
a ListView; if i do regular images, then there is no such limit... 
(which seems weird)
