The library's source code can be downloaded from GitHub.Ĭopyright ©2010-2022 Angus Johnson - Image32 4. Of course, it depends on your definition old days as it could mean 80 column terminals, 640x480, 800圆00. In the old days it certainly felt much easier. Scalable Vector Graphics (SVG) are becoming more popular as an alternative to providing custom sized icons for the various target devices in use. These demonstrate some more complex features of the Image32 library. Simple SVG images in Delphi applications.

The Image32 ZIP package also contains an Examples folder with source code for a number of example applications. The dimensions of the bitmap is set to that of the page at the required output DPI. For that, we supply the canvas handle of a bitmap image. A TImage may hold a bitmap, icon, PNG, GIF or JPEG image. To add an image to a form or data module so that it is available for display by other controls, such as action lists and bitmap buttons, use a TImage List control instead. The RenderToDC () method requires a Windows handle to which page contents can be exported. TImage introduces several properties to determine how the image is displayed within the boundaries of the TImage object.

The remaining units, including Img32.Extra, Img32.Layers and Img32.Transform may be needed less frequently. Delphi Code For PDF-To-Image Conversion Following is a code example for converting a PDF to a high-resolution image. While the Img32 unit contains the core of the Image32 library, several of the following units will also very likely be needed:, , and to access image files (or Img32.FMX in multi-device applications) Img32.Draw and Img32.Vector for line and polygon drawing and Img32.Text for text rendering. The Img32 unit contains TImage32, so this unit must be added to the 'uses' clause to access the library. This works really well with even more extensions supported. As stated in Quick Start, the key element in this library is the TImage32 class which is required for all image rendering operations. Creating a PNG, JPG/JPEG is as simple as calling the Bitmap.SaveToFile with the correct file extension. > you can call Picture.LoadFromFile () without instantiating TGIFImage. > automatically at startup if you have its unit in your Uses clause), then.
> TPicture.RegisterFileFormat () method (which TGIFImage should be doing. Just about all the public structures and functions in the Image32 library are listed below. Now, with that said, if TGIFImage has been registered via the. Image32 - A 2D Graphics Library for Delphi Developers You can use LoadFromFile() and SaveToFile() for simple file loading/saving, and Assign() to/from other TGraphic classes.Img32 Img32.Clipper Img32.CQ Img32.Draw Img32.Extra Img32.FMX Img32.Layers Img32.Resamplers Img32.Storage Img32.Text Img32.Transform Img32.Vector Examples Img32.Panels TWICImage is used very similarly to the TBitmap. If your application is expected to run apart from these requirements, then you will need to recognize this yourself and handle your imaging differently. IMPORTANT: TWICImage is only available on Windows XP SP3 or higher operating systems and relies on DirectX runtime. The formats which are supported depend on the formats which are registered inside of Windows. It wraps the functionality of Microsoft's WIC image. WIC Image stands for Windows Imaging Component. This class, based on a TGraphic (just like a TBitmap), allows you to load virtually any type of image file.

The question is - how to load any format of image into a TBitmap?ĭelphi VCL's Graphics unit contains another class called TWICImage. The TBitmap is widely used as the most standard graphic for performing any type of imaging in Delphi. It is rather common that developers wish to load various types of files into a TBitmap for manipulation, such as JPEG, PNG, or TIFF.
