The Y (height) can be positive or negative just fine and it draws fine. Has anyone seen this before or perhaps my calculation for the W/H aren't making the grade? This is working fine for me for the TopLeft and Bottom Left instances of this. This is my Redraw Method: g.DrawPicture(po.image, TopRightResizeAnchorX, TopRightResizeAnchorY, po.TopRightAnchorDestinationWidth,po.TopRightAnchorDestinationHeight, 0, 0, po.Width, po.Height) This is my calculation for the newWidth: Round( (Window1.CampusMapCanvas.qLastX - Window1.CampusMapCanvas.TopRightResizeAnchorX ) ) This is my calc for the new Height: Round( (Window1.CampusMapCanvas.qLastY - Window1.CampusMapCanvas.TopRightResizeAnchorY) ) TopRightResizeAnchorX = q.TopRightX // This is the current X position of the image for the anchor TopRightResizeAnchorY = q.TopRightY Thank you in advance everyone.

If either width or height goes negative, I would adjust the top/left and make it positive. I don't think DrawPicture handles negative width/height very well, although in your experience it would seem to handle negative height better than negative width. dim X, Y, W, H as integer if po.TopRightAnchorDestinationWidth >= 0 then X = TopRightResizeAnchorX else X = TopRightResizeAnchorX + po.TopRightAnchorDestinationWidth end if po.TopRightAnchorDestinationHeight >= 0 then Y = TopRightResizeAnchorY else Y = TopRightResizeAnchorY + po.TopRightAnchorDestinationHeight end W = abs(po.TopRightAnchorDestinationWidth) H = abs(po.TopRightAnchorDestinationHeight) g.DrawPicture(po.image, X, Y, W, H, 0, 0, po.width, po.height) Top mikecotrone Post subject: Re: Weird Issue with DrawpicturePosted: Sun Apr 14, 2013 8:42 am Joined: Tue Mar 05, 2013 2:33 pm Posts: 37 Location: North Carolina timhare wrote:If your mouse values are integers, you don't need to Round() them.

I will work on making the Width positive and see if the image will show on the "left" side of the anchor (reversed). Also so I am clear as describing pictures can be hard When I drag the bottom/top right I can have my height pos or negative as long as it is to the right/up/down from the anchor position. When this gets weird is when I drag the same bottom/top right now to the left the picture goes to 0,0 is seems and doesn't redraw to the left/up/down at that point. Also When I drag Left Bottom left and top left it doesn't show. But I can cross over to the Right/Top Right and it shows. The H is pos and neg while W is always Pos. However again when I drag to the left/top left the image is not drawn. Does that make sense? Thanks again Tim! _________________ Mike Cotrone - CCIE #8411 R&S, CCIE #8411 Voice Chief Technology Officer Onepath Systems, LLC Real Studio 2012 R2.1 Enterprise, Mac OS, Windows, Ubuntu Linux Top Display posts from previous: All posts1 day7 days2 weeks1 month3 months6 months1 year Sort by AuthorPost timeSubject AscendingDescending Page 1 of 1 [ 3 posts ] -- Over 1500 classes with 29000 functions in one REALbasic plug-in collection.
