Thelibrarian mfc5/1/2023 Modern applications, including those with the new Ribbon toolbar, require several image strips with different sizes and different color depths. If you want to include 2 sizes of icons for example in an application, you must create 2 different image strips. It results in "aliasing" on borders for icons with rounded shapes.Īll icons in an image strip have the same size and the same color depth. In other words, a pixel is either 100% transparent or 100% opaque, there is no variable transparency. The other issue is the poor quality of the borders (around the icons) because it does not permit smooth transparency. The problem of this method is that if you use a pixel of that color in your icon image (not the background), it will be converted as transparent. Usually, the color used is a flashy green RGB(0,255,0) or magenta RGB(255,0,255). Each pixel that have this exact color will be converted as transparent when the image is loaded in the toolbar. It permits creating nice toolbars with smooth edges and shadows.įor color depths 24 BPP or less, the transparency is coded by using a fixed color. In 32 BPP images, the transparency is natively coded in the alpha channel. Image lists support image strips in different color depths: 4 BPP (16 colors), 8 BPP (256 indexed colors), 24 BPP (RGB true color) and 32 BPP (RGB true color with alpha channel). This image is called an "Image Strip" or "Bitmap Strip": That way, all the images are added automatically in one single operation. Instead, it is much easier to use a wide bitmap containing several images placed side-by-side. To populate the toolbars, you can add each image separately from an icon file (ICO format), but this is not recommended. The Images Lists are created in background, so you don't have to deal with this. Note that modern UI SDKs and developement libraries such as MFC permit associating the images directly to the toolbars. First you must create and populate an Image List, then associate it to the toolbar. This is done through Image Lists objects ( read more about Image Lists). When you create your toolbar, in addition to creating the buttons, you must populate it with the images you want to associate with each button. In this lesson, we'll see how to modify/create images used to populate icons in toolbars: image strips.Įach command in a toolbars is represented by a button containing an icon. This model never forgets my network information, and printing from my Laptop and Phone have proceeded without issue thus far.If you're a developper, you probably use toolbars in your applications. I just need to enter a 4 digit code and the scanner knows where to send it. I easily set up a shortcut and it remembers my Google Drive information. I primarily purchased this model because I wanted an automatic scan to Google Drive feature from an inexpensive home printer. Connection to my home network just seems to happen simple and automatic and it doesn't lose or forget that connection. It literally took 5-10 minutes to set up and the instructions were accurate. The Brother line of products, including this model, is a refreshing change. Expensive ink and ink subscriptions are just another pain I don't need. Web connections are difficult and always need to be maintained. HP's products have become increasingly difficult to use and expensive to maintain. This is probably a review against HP more than a review for Brother. Very glad I went back to the Brother brand
