Convert images using Python language
Convert Images, Photos and other to build Python image processing applications.
Aspose.Imaging for Python via .NET API contains different image processing features for programmers. Programmers can use it in source code to convert raster and vector images, such as photos and pictures to PSD, PDF, APNG, BMP, TIFF, GIF, PNG, DICOM, HTML5 CANVAS, WEBP, WMF, EMF, SVG, JPG, JPEG2000 and other image formats. API contains not only features for conversions, but also different filters, graphics processing, memory strategies, crop, resize, adjust and another used operations.
How to convert Image to BMP, JPG, PNG
Using Aspose.Imaging for Python via .NET API, cross-format conversion is easy process. Here are few common examples such as image to bmp, image to jpg, image to png. Process is to load the image using Image.Load . Create an object of selected image format options with specified settings. At the end call the Save Method .

How to convert SVG image to Raster BMP, PNG, JPG
Conversion of SVG image is the same, Load SVG image, Use needed image saving options and calling the Save method. Image API provides SvgRasterizationOptions for setting PageWidth, PageHeight and raster images use their VectorRasterizationOptions property for initialization and getting SvgRasterizationOptions options.
