Re: Object is not an image when Crop command
Thanks Wilhelm for share :) I modified the oval graphic to one polygon with irregular shape and work! :) I read the discussions and I understand more about the masking issues. I don't see difference between some scripts respecting the edges problem. Also I haven't clear the comparation of rgb pixels...

Re: Object is not an image when Crop command
Hi Scott, Thanks for the stack. Very cool the effect. But I need to move the masked object, and your idea of use the BackgroundPattern inspired me and I found one solution that at first step solve my problem. I have a image and some graphics polygons over. The user select one of them and extract the image inside the edges of the graphic. And then the user can move if they want or duplicate. the selectedobject is the polygon on mouseUp lock screen put the rect of the selectedobject into tRect import snapshot from rect tRect of image picture put the id of last image into tSnapshotId set the backgroundpattern of the selectedobject to tSnapshotId delete img id tSnapshotId set the layer of the selectedobject to top set the ink of the selectedobject to srcCopy unlock screen end mouseUp What you think about? Can I have any problem of memory if I use more graphics with backgroundpattern? And other question to explore :) How can empty the area of the image that is inside the graphic? Modifying the imagedata? Or select a range of pixels and asign a new color?

You can modify pixels of an image, but maybe it would be less complicated to overlay a colored overlay object where you want it and create a new snapshot to apply as the backgroundPattern.

Re: Object is not an image when Crop command
Hi, You can modify pixels of an image, but maybe it would be less complicated to overlay a colored overlay object where you want it and create a new snapshot to apply as the backgroundPattern. This is what I doing but I can't erase the background or overlay with the new color. The objective is to change the wall color with the shadows and some of the details. Imagine a red wall, I create a poly with the shape of the wall, then I create a snapshot and put it as backgroundpattern into the poly. Then I can change the color of it to white but I loss the major of the shadows and details, only I can play with the blendlevel to show of the detail but this is borrowed. Any idea how to deal with this? Also I read the article of Kevin about the imagedata, maskdata and alphachanel. I don't know if is posible extract some chanel to use as shadow...

Object is not an image when Crop command
Hi List, I try to crop a image with the rect of a graphic. tObject is a graphic selected by the user. img picture is a image loaded by the user from disk The user move the graphic over the image and crop it, but only I get Error: object is not an image?? The graphic is irregular polygon, I mean that is not a rectangle or a box.. The code: put the rect of the selectedobject into tObject crop img picture to rect tObject Any idea? :) Salut, Josep -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/Object-is-not-an-image-when-Crop-command-tp2171784p2171784.html Sent from the Revolution - User mailing list archive at Nabble.com. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Recently, Devin Asay wrote: Crop only works with a rectangle. There may be others on the list who have figured out how to use an irregular shape as an image mask. You can't. You can only group the graphic and image and use combined ink effects. Very limiting. You can see the Spotlight demo on this page as an example: http://www.tactilemedia.com/site_files/software/tutorials.html Alternatively, you can set the backPattern of the graphic to the ID of the image, but there's no control over how the image is positioned relative to the graphic. I imagine one could use the hidden point technique of a polygon (adding a space before an after a point in the polygon's point list) to establish left and top offsets for the backPattern, effectively offsetting the image within the graphic. But this will only work with polygon graphics.

Re: Object is not an image when Crop command
Mmhh.. but with the backpattern in correct position how crop only these shape... Sorry for my questions, never I must fighted with graphics issues in Rev until now... :) The following is posible? 1 Export the snapshot ruled by the rect of a polygon over one part of the image. 2 Load the exported image and superpose the same graphic and make transparent the difference. I don't know if I explain myself. 3 Save as transparent the image 4 Load the transparent image over the original image. It's for simulate painted walls, and I need extract the windows, picture frames and other nice stuff... :P Salut, Josep -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/Object-is-not-an-image-when-Crop-command-tp2171784p2172800.html Sent from the Revolution - User mailing list archive at Nabble.com. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
