Hi,



I have no Idea anymore. Please help.



filterRecord-%26gt;advanceState() failed with errorcode filterBadParameters == -30100.

inData is set, but outData is still 0 after calling advanceState().



If I ignore this error message an proceed I'll see something like a high magnified version of the original pixels. filterRecord-%26gt;advanceState() is called for creating the preview image.



All I could debug is that it must have to be an issue with the size of inRect or/and outRect.



So my quesion is:

In which case do advanceState() return with this error code?

What could be gone wrong?

What can I check?

In which range should the image rects (in, out, mask) be?

Perhaps you are requesting a Rect that's larger than what Photoshop will give you.



gFilter-%26gt;inputRate will reduce the size of what Photoshop will give you. To figure out what Photoshop can give you, you might want a function like:



VRect getScaledFilterRect()

{

//This is an accessory function that calls GetFilterRect

//---but also scales it--- to account for gFilterRecord-%26gt;inputRate

//This is typically less dangerous than GetFilterRect()

VRect returnRect = GetFilterRect();



ScaleRect(returnRect, 1, gFilterRecord-%26gt;inputRate); //I can't remember if you call gFilterRecord-%26gt;inputRate or something %26lt;%26lt; 16



return returnRect;

}



Make sure that your inRect() isn't larger than GetFilterRect *after* it's been scaled.



Your problem might be something entirely different of course...
