Re: 295 png import images
It didn't work here - 'filename' isn't a button property, and setting the icon to a url doesn't work either. However, you can make an image object act pretty much like a button, responding to mouse clicks and such.

Re: 295 png import images
Do you need to have all 295 layers presented at once in full resolution? Could you perhaps use thumbnails for initial button presentation and then pull in the detailed layers as needed? If you're layering the images, could you use a snapshot to contain the set of all underlying layers as a new layer is added? Best, Keith..

Re: 295 png import images
Hi Phil, The trick is to use an image, set the icon of the button to the id of said image, and then change the filename of the image; your button will automagically be repainted when you change the filename of the image control. As a quick test, I created a stack with a button and an image; I named the image control MyButtonIcon; and then I set the script of the button to: ## on mouseUp answer file Select an image for my icon if it is empty then exit mouseUp set the fileName of image MyButtonIcon to it if the icon of me is 0 then set the icon of me to MyButtonIcon end mouseUp ## When I click the button, I can go find an image file and the button gets it as a shiny new icon :-) HTH, Jan.

I guess even a dedicated image editing app like PhotoShop or Pixelamator would choke on this task!

Re: 295 png import images
Vector graphics is a tough nut to crack. Think postscript. Perhaps the better approach would be for someone to make an external that tied into a real postscript library (but then there is licensing) and provided some fairly basic commands that allowed the user to programmatically create real vector objects. But then of course people will want to edit those objects, and doing it natively in Livecode would be a nightmare. I suppose then the external would have to provide an editing window. Then people would want layers, and transparency effects and before you know it, someone just rewrote Adobe Illustrator! LOL! Maybe the better thing after all is to create vector objects in an app that is made for it, then export as a png?

Beyond the limits of RAM we have in nearly everything short of a supercomputer, on what monitor will you be able to display 295 images at 1900 x 2200px each? Even a single row of just 50 such images will require a monitor more than 100 feet wide. On even the largest consumer monitor only a very few of those images can be displayed at any given moment, with most of them cropped at the display's edge. Normal amounts of RAM and LC's native performance should be sufficient for displaying what's possible. If you don't really need to show 295 large images but instead will be showing only thumbnails, you'll want to generate the thumbnails one at a time first (won't take too long and if you cache them it only needs to be done once). If you're only showing a few at a time you should be able to swap out the filename of the source image on the fly as needed.

Re: 295 png import images
If you're layering the images, could you use a snapshot to contain the set of all underlying layers as a new layer is added? -- No, I need dynamic showing/hiding as a user peels on and off the layers to study how the art is applied to the page. But surely, at any given time, what the user sees on screen is only the layer being 'peeled' and the net effect of all underlying layers? So, you could use just two images in RAM at any time: layer n and a snapshot of layers 1 to n-1 You can store not only the 295 individual layer files but also 294 snapshot files of layer 1, 1+2, 1+2+3... 1+2+3...(n-1) When a new layer is added, create a new snapshot of the previous snapshot plus the last image. If the point of your app is to work down through the layers, you can pre-build the set of snapshots to be displayed under any specific layer. The order of layers could be defined in a list field, so you (or the user) can select the 'peel' and its underlying snapshot. This list could drive a loop routine that rebuilds the snapshots iteratively from layer-1 up. If the order of layers is changed, you know from how far back down the list the set of snapshots needs to be rebuilt.

Because everything is put into ram, I am hitting a wall. And I need to keep the images large enough to allow users see the page at actual size due to the art design is complex. Can the user insert/remove layers in any order or is there a definite sequence? If it's the latter then you could create 295 composited images - the first 'containing' only 1 layer, the last all 295. Store them all externally and just set the filename of a single image object. Add or remove a layer and you simply increment or decrement the filename. You could easily create these composited images in LC using just 2 overlaid image objects. If your filenames go something like orig001 to orig295 for the layer images and comp001 to comp295 for the composited images then you'd start off with orig001 (image 1) and orig002 (image 2) in the image objects and export a snapshot of these to create comp002. Then set the filename of image 1(bottom) to comp002 and the filename of image 2 to orig003 and export another snapshot (comp003). Keep going until you have 295 new images (orig001 also becomes comp002). Now you can use a single image object to display your composited layers and a couple of buttons to pile them on and take them off. Terry...
