If you want to make manual color and exposure corrections, there are half a dozen sliders to let you do exactly that. In our tests, this worked particularly well on landscapes but wasn't always great for other subjects. You can also choose individual photos to enhance with the software's one-click optimization tool. Importing pictures is a breeze, and once they've been added to the pool, you can select several at once to rotate or mirror, saving you valuable time. Its interface is clean and uncluttered, and utterly devoid of ads (although you'll need to submit an email address before you can start using it). This delay allows LiveCode to process any other events that may have occurred ‚Äì mouse clicks on the folder tree for example.If you've got a lot of photos that you need to edit in a hurry, Ashampoo Photo Optimizer could be the best free photo editor for you. The last thing the "processImage" handler does is call itself using the "send" command but with a small delay. The "processImage" handler processes a single image file into a thumbnail (as outlined in the section above). Luckily, LiveCode provides a simple way to loop through the list while still allowing responsiveness to other events ‚Äì the "Send" message loop.įirstly, the reloadThumbnails function starts the processing loop up by sending itself the "processImage" message right away ‚Äì tFiles contains the list of image files send "processImage tFiles" to me in 0 millisecs However, doing things this way means that the application is locked up and unresponsive until all images have been processed ‚Äì there is no-way to change folder, view an image or even cancel the listing until all files have been processed. When it came to processing the list of image files into thumbnails I did it first using a simple loop repeat with line tFile in tFileList Again, you can look up import snapshot in the Dictionary for more information on how to use this versatile command. You can see exactly how I used this in the Image Browser, the script is at the bottom of the "thumbnailView" group script, in the function called "processImage". Optionally, save the thumbnail image to disk cache Clean up after ourselves delete the last image delete image "Foo"ĩ. Put the data of the snapshot into our thumbnail set the text of image id tID to the text of the last imageĨ. Create a snapshot of the temporary (resized) image import snapshot from rect ( the rect of image "Foo" ) of image "Foo"ħ. The image will be automatically resized to fit the new temporary imageĦ. Set the filename of the temporary image to the image on disk set the filename of image "Foo" to tFileĥ. Create a temporary blank image of the correct size for the thumbnail create invisible image "Foo"Ĥ. Create the new empty thumbnail image create image in group "thumbnailView"ģ. By default, the global paintCompression property is set to "rle" in standalones and "png" in the development environment but we want it to be "png" in standalones too. This specifies the compression format used for storing an image. Below you will find the main steps to achieve this.ġ. The easiest way to achieve this is to use the import snapshot command. This file can then be written out to disk to create a thumbnail cache. What we actually want to achieve is to create a thumbnail that just contains that actual data of the smaller, resized image. Although this will work, you will very quickly run out of memory if you try and load in thumbnails of a folder containing several hundred large images. However, when you resize an image in LiveCode you still retain all the data that was in the original file. As you know, it is very easy to load images and resize them ‚Äì and you would be forgiven for thinking that this is all that is required to create a thumbnail view of an image file.
