      I am enjoying the new features in Version 310 (324). The new ribbon seems to be working well, though figuring out where the former buttons went takes a few seconds to locate.

      My problem is with the Background Images feature. It was kludgy—but workable—in previous versions, but now I am having some serious problems with it. At least in previous versions, when you assigned an image to a view perspective, it remained yellow and editable until you clicked on it to “lock” it.

      I have tried everything I can figure out in my attempt to resize and align the background image to the reference lines in a new model, to no avail. When I have the General/Edit window open, and the inserted image in the viewport is yellow with handles showing, I can’t click or move the handles because the Edit window is open (it flickers when the left mouse button is clicked). When I close the editing window, the image goes white and can’t be grabbed at all. This behavior occurs in both new models and with ones I have been working on for several years.

      Is this a bug that needs fixing, or am I missing something? I noticed you have already issued a new update (325) to fix several things in the 324 update.

      Thanks for your efforts. Overall, I really enjoy the program and have been mentoring several ship modelers in its use. But this problem has got me baffled.

      Hi Terrance,

      Thank you for your kind words, we work hard to make DELFTship as nice as we can. You are right that the background image system was kludgy, that is why we overhauled it. The manual should highlight most of the changes.

      Because we found that background images were becoming more important in multiple tools, we dropped the ‘show in’ check boxes, and made them available everywhere by default. You can then choose to show / hide them in each window as required.

      Placing, scaling, cropping, rotating etc can now be done from the background image window. In the 2D view you drag a red crosshair to the origin (the 0,0 coordinate of your perspective). In the 3D view you can then scale the image to fit.

      I hope you will find the use of this system!

      Hello Maarten.

      Thank you for your response.

      I think the new Background Images interface is going to work well.

      The problem I am having is when I have added an image using the Open button in the General window, I see this:

      Open-Image-small

      In former versions of the program, when the image is highlighted with the “handles”, you can resize the image to fit between perpendiculars and waterlines, etc., directly in the program window. However, if you attempt to adjust the image by grabbing the handles now, nothing happens. The General/Edit window flickers just like standard Windows dialog boxes do when you attempt to perform another function before closing the dialog box.

      So, when I click Accept in the Background Image General box, I see this:

      Saved-Image-small-1

      The image set in the program window is no longer highlighted and cannot be adjusted.

      It seems that the intent with the new interface is that the user identifies the origin in the new image, aligns the image horizontally, then resizes the image to fit the model guidelines (perpendiculars, stations, waterlines, etc.). I haven’t tried this, but it seems that it would require repeatedly resizing the image to adjusting the number of pixels to fit. Also, since the Resize dialog does not proportionally change width with height or vice versa, it seems you would have to first set one dimension using iterative changes, then adjust the other. Depending on the resolution and size of the base image, one has no idea how much to resize the image.

      It seems that permitting direct manual manipulation of the image in the program window is still the best method to resize background images.

      Again, if I am missing something, please explain, step by step, how this is supposed to work. The manual isn’t clear on process. It just describes what the different functions are intended to do.

      Thanks.

      Terry

      By the way, I have two monitors, so that is why the images in the previous post look the way they do.

      OK, I finally figured it out!

      There are two tabs in the Edit window that I failed to see. They are labeled “2D” and “3D”. In the manual, I thought these terms were referring somehow to the main program window, not the Edit window.

      2D-3D

      After figuring that out, resizing and positioning the image is very simple and intuitive.

      I did discover that to update the background image in the main program window, you have to switch views. The image doesn’t resize dynamically with changes in the Edit window.

      Sorry for the confusion.

      Hi Terrance,

      I’m glad you figured it out. Background images are used in various other modules of DELFTship too. That is why we decided to keep all editing features (including resizing) of background images central in the background images window wit the added advantage that continuous switching between the background image window and the hull modeling window is no longer required.

      Thanks Marven.

      I’ve had the opportunity now to import a full set of views for one of my collaborator’s projects. This new approach is so much easier in many important ways.

      I am promoting your software in the Model Ship World site. I think many modelers will want to use it for refining old plans that are notoriously inaccurate.
